Problem with serving pictures in Django - python

I'm trying to create my first site in django and I've run into a problem. I'm trying to serve pictures,but it isn't working correctly. I have it set up in the following way:
In settings.py:
MEDIA_ROOT = 'C:/Users/John/Documents/My Dropbox/Infostuff/filmsite/media/'
MEDIA_URL = 'localhost:8000/static/'
ADMIN_MEDIA_PREFIX = '/admin-media/'
In urls.py:
(r'^static/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT}),
It looks like this in the template page:
<img src="{{MEDIA_URL}}{{a.picture.url}}">
And it is parsed to this:
<img src="localhost:8000/static/portrets/0000138_Leonardo_D.jpg">
When I open the html page it doesn't display the pictures (I get the broken picture icon). If I however go to view the source and copy the above url and past it directly into my browser it does load the picture. What am I doing wrong?
I'm using Django 1.2. I'm not using Apache yet, because I would first like to get it working in a development environment.
PS: This is the first time I'm asking a question on this site, if I did something wrong, please tell.

use:
MEDIA_URL = 'http://localhost:8000/static/'
or
MEDIA_URL = '/static/'

Your MEDIA_URL should just be '/static/' - or, if you must, 'http://localhost:8000/static/'. Otherwise your browser is interpreting the localhost as part of the path, not the domain.

Ok, I feel very stupid...
I had to change
MEDIA_URL = 'localhost:8000/static/'
to
MEDIA_URL = 'http://localhost:8000/static/'
and then I had change
<img src="{{MEDIA_URL}}{{a.picture.url}}">
to
<img src="{{a.picture.url}}">
Thank you for your time.

What version of Django are you using?
Can you post the generated HTML code? if the URL works when you copy and paste in the browser, it might be an html issue as well.
Have you looked at this page yet?
http://docs.djangoproject.com/en/dev/howto/static-files/
Update:
Can you post the model for a? is a.picture an image field? If so, then you don't need to put the MEDIA_URL in your img src, since it is already an absolute url and it should include the MEDIA_URL already. try removing that and see if it works.
<img src='{{a.picture.url}}' />
For more info see this page.

Sending Email with Image inside the body of the html - Django [duplicate]

I'm new to Django and I'm trying to learn it through a simple project I'm developing called 'dubliners' and an app called 'book'. The directory structure is like this:
dubliners/book/ [includes models.py, views.py, etc.]
dubliners/templates/book/
I have a JPG file that needs to be displayed in the header of each Web page. Where should I store the file? Which path should I use for the tag to display it using a template? I've tried various locations and paths, but nothing is working so far.
...
Thanks for the answer posted below. However, I've tried both relative and absolute paths to the image, and I still get a broken image icon displayed in the Web page. For example, if I have an image in my home directory and use this tag in my template:
<img src="/home/tony/london.jpg" />
The image doesn't display. If I save the Web page as a static HTML file, however, the images display, so the path is correct. Maybe the default Web server that comes with Django will display images only if they're on a particular path?
Try this,
settings.py
# typically, os.path.join(os.path.dirname(__file__), 'media')
MEDIA_ROOT = '<your_path>/media'
MEDIA_URL = '/media/'
urls.py
urlpatterns = patterns('',
(r'^media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT}),
)
.html
<img src="{{ MEDIA_URL }}<sub-dir-under-media-if-any>/<image-name.ext>" />
Caveat
Beware! using Context() will yield you an empty value for {{MEDIA_URL}}. You must use RequestContext(), instead.
I hope, this will help.
In production, you'll just have the HTML generated from your template pointing to wherever the host has media files stored. So your template will just have for example
<img src="../media/foo.png">
And then you'll just make sure that directory is there with the relevant file(s).
during development is a different issue. The django docs explain it succinctly and clearly enough that it's more effective to link there and type it up here, but basically you'll define a view for site media with a hardcoded path to location on disk.
Right here.
I do understand, that your question was about files stored in MEDIA_ROOT, but sometimes it can be possible to store content in static, when you are not planning to create content of that type anymore.
May be this is a rare case, but anyway - if you have a huge amount of "pictures of the day" for your site - and all these files are on your hard drive?
In that case I see no contra to store such a content in STATIC.
And all becomes really simple:
static
To link to static files that are saved in STATIC_ROOT Django
ships with a static template tag. You can use this regardless if
you're using RequestContext or not.
{% load static %} <img src="{% static "images/hi.jpg" %}" alt="Hi!" />
copied from Official django 1.4 documentation / Built-in template tags and filters
In development
In your app folder create folder name 'static' and save your picture in that folder.
To use picture use:
<html>
<head>
{% load staticfiles %} <!-- Prepare django to load static files -->
</head>
<body>
<img src={% static "image.jpg" %}>
</body>
</html>
In production:
Everything same like in development, just add couple more parameters for Django:
add in settings.py STATIC_ROOT = os.path.join(BASE_DIR, "static/")(this will prepare folder where static files from all apps will be stored)
be sure your app is in INSTALLED_APPS = ['myapp',]
in terminall run command python manage.py collectstatic (this will make copy of static files from all apps included in INSTALLED_APPS to global static folder - STATIC_ROOT folder )
Thats all what Django need, after this you need to make some web server side setup to make premissions for use static folder. E.g. in apache2 in configuration file httpd.conf (for windows) or sites-enabled/000-default.conf. (under site virtual host part for linux) add:
Alias \static "path_to_your_project\static"
Require all granted
And that's all
I have spent two solid days working on this so I just thought I'd share my solution as well. As of 26/11/10 the current branch is 1.2.X so that means you'll have to have the following in you settings.py:
MEDIA_ROOT = "<path_to_files>" (i.e. /home/project/django/app/templates/static)
MEDIA_URL = "http://localhost:8000/static/"
*(remember that MEDIA_ROOT is where the files are and MEDIA_URL is a constant that you use in your templates.)*
Then in you url.py place the following:
import settings
# stuff
(r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}),
Then in your html you can use:
<img src="{{ MEDIA_URL }}foo.jpg">
The way django works (as far as I can figure is:
In the html file it replaces MEDIA_URL with the MEDIA_URL path found in setting.py
It looks in url.py to find any matches for the MEDIA_URL and then if it finds a match (like r'^static/(?P.)$'* relates to http://localhost:8000/static/) it searches for the file in the MEDIA_ROOT and then loads it
/media directory under project root
Settings.py
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
urls.py
urlpatterns += patterns('django.views.static',(r'^media/(?P<path>.*)','serve',{'document_root':settings.MEDIA_ROOT}), )
template
<img src="{{MEDIA_URL}}/image.png" >
If your file is a model field within a model, you can also use ".url" in your template tag to get the image.
For example.
If this is your model:
class Foo(models.Model):
foo = models.TextField()
bar = models.FileField(upload_to="foo-pictures", blank = True)
Pass the model in context in your views.
return render (request, "whatever.html", {'foo':Foo.objects.get(pk = 1)})
In your template you could have:
<img src = "{{foo.bar.url}}">
Your
<img src="/home/tony/london.jpg" />
will work for a HTML file read from disk, as it will assume the URL is file:///home/.... For a file served from a webserver though, the URL will become something like: http://www.yourdomain.com/home/tony/london.jpg, which can be an invalid URL and not what you really mean.
For about how to serve and where to place your static files, check out this document. Basicly, if you're using django's development server, you want to show him the place where your media files live, then make your urls.py serve those files (for example, by using some /static/ url prefix).
Will require you to put something like this in your urls.py:
(r'^site_media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': '/path/to/media'}),
In production environment you want to skip this and make your http server (apache, lighttpd, etc) serve static files.
Another way to do it:
MEDIA_ROOT = '/home/USER/Projects/REPO/src/PROJECT/APP/static/media/'
MEDIA_URL = '/static/media/'
This would require you to move your media folder to a sub directory of a static folder.
Then in your template you can use:
<img class="scale-with-grid" src="{{object.photo.url}}"/>
I tried various method it didn't work.But this worked.Hope it will work for you as well. The file/directory must be at this locations:
projec/your_app/templates
project/your_app/static
settings.py
import os
PROJECT_DIR = os.path.realpath(os.path.dirname(_____file_____))
STATIC_ROOT = '/your_path/static/'
example:
STATIC_ROOT = '/home/project_name/your_app/static/'
STATIC_URL = '/static/'
STATICFILES_DIRS =(
PROJECT_DIR+'/static',
##//don.t forget comma
)
TEMPLATE_DIRS = (
PROJECT_DIR+'/templates/',
)
proj/app/templates/filename.html
inside body
{% load staticfiles %}
//for image
img src="{% static "fb.png" %}" alt="image here"
//note that fb.png is at /home/project/app/static/fb.png
If fb.png was inside /home/project/app/static/image/fb.png then
img src="{% static "images/fb.png" %}" alt="image here"
I've had the hardest time figuring this out so I am making this post to explain as clearly as i can, what worked for me, to help someone else.
Let's say you have a project called project_name. and an app called app_name. your root directory should look like this:
/app_name
/project_name
manage.py
DEVELOPMENT.
while in development mode, your CSS and JS files should be inside ./app_name/static/app_name/..
however your images should be inside ./app_name/static/media/..
now add these to settings.py :
If this not already there, add
STATIC_URL = '/static/'
This tells Django where to find all the static files.
MEDIA_URL = '/media/'
This points Django to the folder where your images are, after it loads static. In this case it is /media/ because our images are in /static/media.
next, you should put this in the individual template where you need the image (I thought putting a single {% load static %} in the general layout.html template would suffice, it didn't):
{% load static %}
<img src="{% static image_name %}>
depending on how you set up your project, image_name could be the exact name of the image file like "image.jpg", a variable for an image field like user.image etc
lastly, go into the project_name urls.py (same folder as settings.py) and add this line to the end:
from django.conf import settings
from django.conf.urls.static import static
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
basically telling Django to use a work around so you can see use the images in development.
That is all. your project will now display images while you are writing and testing your code(development)
PRODUCTION.
When you want to deploy your project, there are some extra steps you need to take.
Because Django does not serve images as static files during production, you have to install a Middleware called Whitenoise.
http://whitenoise.evans.io/en/stable/#installation
pip install whitenoise
Then add the following to settings.py:
look for MIDDLEWARE and add just under django.middleware.security.SecrutiyMiddleware:
'whitenoise.middleware.WhiteNoiseMiddleware',
Next we have to define our paths, this is because in production Django will basically collect all the static files from all our apps and rearrange them in a single folder.
Add the following to settings.py:
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
This tells Django where to put static files when it collects them. In this case we are telling Django to put the files in the root folder. so after collectstatic runs our app would look like
/app_name
/project_name
/static
manage.py
Then add:
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
This tells django where to put files that a user who on our site uploads..
Next,we want to go up and change Debug to False.
Debug = False
Debug mode is used for testing in development, and in production you don't want your app displaying error codes and the names of files and lines where something went wrong. potential security threat. Once you turn debug mode to false, Django changes how it serves the static files. so ordinarily, if you were to run your app now, you won't see the images..
with these done, now you are ready for production. to test that everything is okay, you can run:
python manage.py collectstatic
(type yes if prompted)
Django will collect all the static files and arrange them as necessary. if you run your project now, with debug still turned off you should see your images. you can even now delete the individual static folders in app_name or any other apps you have, if you want because Django will not use them in production. Once debug is off, Django only uses static from the collected static folder.
You can now deploy your project
If you give the address of online image in your django project it will work.
that is working for me. You should take a shot.
Also check that the problem may not be due to path, but file name or extension. While failing to dislay an image added to base.html template, the error was found related to image file extension. If you are storing the image in jpeg format, use .jpg as the extension in the img tag
<img src="{% static 'logo.jpg' %}" alt="Logo">.
Just give a try copying static folder from base path to public_html folder.
cp -r static/ ~/public_html/

Django admin site not loading CSS

Not sure what is going on, but my admin page on my Django site isn't loading any CSS. Not sure if it has to do with python manage.py collectstatic but ever since I served my static files using this, my admin page doesn't load with CSS and instead, it's plain HTML. This same issue is happening with a few projects of mine when using collectstatic. Any ideas? They'd be appreciated. Since I don't know what the issue is or where to start, I'm not sure what code to provide. If you want to see anything, let me know.
I've noticed when I viewed the source of the admin page and clicked on the css links (<link rel="stylesheet" type="text/css" href="/static/admin/css/base.css">), the base.css file seems to be corrupted maybe ? What the base.css looks like All the other css files when clicked are readable. What the other css files look like
Add the following code to the settings.py file
PROJECT_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = os.path.join(PROJECT_DIR, 'static')
STATIC_URL = '/static/'
After that add the following in the URL:
static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

Django Static URL not rendering images correctly

I'm writing a view that displays a set of images on a page.
This is the model
#models.py
class Movie(models.Model):
title = models.CharField(max_length = 500)
poster = models.ImageField(upload_to = 'qanda/static/movie_posters')
#index.html
<img src = "{{ STATIC_URL }}movie_posters/{{ movie.poster }}"></a>
When I runserver, the image doesn't appear. The URL the image is trying to load is
http://127.0.0.1:8000/static/movie_posters/qanda/static/movie_posters/image.jpg
When the URL it should be trying to load is
http://127.0.0.1:8000/static/movie_posters/image.jpg
My assumption is that since movie.poster is located at 'qanda/static/movie_posters', when I render it on HTML, it is loading the Static URL (127.0.0:8000/static) and then the location 'qanda/static/movie_posters' at the end. How do I make the image render correctly?
There are two pieces of how image url is calculated.
First in your settings.py you define MEDIA_ROOT. MEDIA_ROOT specifies an absolute folder on your computer where media will be stored. So for example for these settings:
MEDIA_ROOT = '/abs/path/to/media/'
and if you have a field
models.ImageField(upload_to='movie_posters')
then images will be stored at:
/abs/path/to/media/movie_posters/
/abs/path/to/media/movie_posters/poster.jpg <- example
This deals with where media is stored on your hard drive.
Second piece is how to calculate urls for these media files. For that you define MEDIA_URL in your settings.py. That essentially maps a URL to your MEDIA_ROOT location. So then if your MEDIA_URL is:
MEDIA_URL = 'http://localhost/media/'
Then if you want to access an image stored at movie_posters/poster.jpg which has an absolute path of /abs/path/to/media/movie_posters/poster.jpg, its URL should be http://localhost/media/movie_posters/poster.jpg. You can compute the URL by doing:
{{ MEDIA_URL }}{{ movie.poster }}
Please note that I am using MEDIA_URL instead of STATIC_URL. Those are not the same thing. Computing urls like that however is not very neat. Thats why Django's ImageField and FileField have an url attribute:
{{ movie.poster.url }}
Django will then compute the proper url depending on your MEDIA_URL setting.
Note:
For all of this to work, you have to have a separate media server running. Django does not serve any media files. In development it is only capable of serving static file (not same as media files). So in development one nice trick to serve media files is to use Python's simple web server. For that, open a new terminal (on Linux and Mac) or Command Prompt (on Windows) window/tab and navigate to your media folder. Then just execute the following command there:
python -m SimpleHTTPServer 8090
and make sure your setting is:
MEDIA_URL = 'http://localhost:8090/'
and then Python will serve your media files. That works nice for development.
If you want to serve your media just using the development server you can add this for the time being to your urls.py
urlpatterns = patterns( ...all your awesome urls...) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
you can define a custom template tag which returns the basename of the URL like this:
from django import template
import os
register = template.Library()
#register.filter
def getBasename(myURL):
return os.path.basename(myURL)
this should go in your custom template tags (eg. customTemplateTags.py) file within your templatetags directory of your app.
Then you can use the filter in order to get only the image filename, not the entire URL.
{% load customTemplateTags %}
<img src = "{{ STATIC_URL }}movie_posters/{{ movie.poster.url|getBasename }}"></a>

Django static files won't load

i'm a Django newbie working on my first project and having a problem with static files.
I have created a simple auth system using django.contrib.auth consisting of two templates: mysite/templates/index.html and mysite/templates/registration/login.html. I have global static content in mysite/static which I want to be able to access on all templates rendered by all apps.
mysite/templates/index.html contains <img src="{{ STATIC_URL }}pics03.jpg"/> which renders as "static/pics03.jpg" and loads fine when I visit the url localhost:8000/
mysite/templates/registration/login.html contains <img src="{{ STATIC_URL }}pics03.jpg"/> which also renders as "static/pics03.jpg" and does not load when I visit the url "localhost:8000/accounts/login/"
In my urls.py I have:
urlpatterns = patterns('',
url(r'^$', 'mysite.views.home'), # plays index.html template
url(r'^accounts/login/$', 'django.contrib.auth.views.login'),
In my settings.py I have:
PROJECT_DIR = os.path.dirname(__file__)
STATICFILES_DIRS = (
# Put strings here, like "/home/html/static" or "C:/www/django/static".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
os.path.join(PROJECT_DIR,'static'),
)
STATICFILES_FINDERS = (
'django.contrib.staticfiles.finders.FileSystemFinder',
'django.contrib.staticfiles.finders.AppDirectoriesFinder',
)
STATIC_URL = '/static/'
STATIC_ROOT = ''
I was under the impression that Django should be looking for global static content in STATICFILES_DIRS, but it doesn't find the static content for login.html even if I change the url in there to an absolute path to the static folder. Can anyone shed any light on this?
Your problem is that you arent listening to the URL "/static/" nowhere in your urls.py
If you serve your application via a webserver like apache or nginx then this is normal as the webserver would handle the static files itself.
For development Django comes with a built-in static server
to urls.py, at the very end add
from django.contrib.staticfiles.urls import staticfiles_urlpatterns
urlpatterns += staticfiles_urlpatterns()
What this does is to add the /static/ url and let you serve those without a webserver.
This is equivalent to
url(
regex=r'^static/(?P<path>.*)$',
view='django.views.static.serve',
kwargs={'document_root': settings.STATIC_ROOT,}
)
some people will tell you that you need to wrap the URL-rules in a "if settings.DEBUG" to use the dev-only rules, but this isnt needed at all and actually i find that to be a bad advice.
Are you having trouble when using the build in runserver or are you serving using Apache or similar? I've struggled with this a bit. The documentation I follow is: https://docs.djangoproject.com/en/stable/howto/static-files/
The second part is key when you are ready to deploy. You need to define a static root (which will be empty to begin with) and run the manage.py collectstatic command to move the static files from throughout your project into that folder. Then you can serve them from there.
Does changing STATIC_ROOT='' to STATIC_ROOT='/' help?
It seems to me the only difference is that static/pics03.jpg (relative path) exists on the home page, but doesn't on the other.
The absolute path /static/pics03.jpg exists in both cases. If changing STATIC_ROOT doesn't help, just add a / to the beginning of the urls.

How do I include image files in Django templates?

For about how to serve and where to place your static files, check out this document. Basicly, if you're using django's development server, you want to show him the place where your media files live, then make your urls.py serve those files (for example, by using some /static/ url prefix).
Will require you to put something like this in your urls.py:
(r'^site_media/(?P<path>.*)$', 'django.views.static.serve',
{'document_root': '/path/to/media'}),
In production environment you want to skip this and make your http server (apache, lighttpd, etc) serve static files.
Another way to do it:
MEDIA_ROOT = '/home/USER/Projects/REPO/src/PROJECT/APP/static/media/'
MEDIA_URL = '/static/media/'
This would require you to move your media folder to a sub directory of a static folder.
Then in your template you can use:
<img class="scale-with-grid" src="{{object.photo.url}}"/>
I tried various method it didn't work.But this worked.Hope it will work for you as well. The file/directory must be at this locations:
projec/your_app/templates
project/your_app/static
settings.py
import os
PROJECT_DIR = os.path.realpath(os.path.dirname(_____file_____))
STATIC_ROOT = '/your_path/static/'
example:
STATIC_ROOT = '/home/project_name/your_app/static/'
STATIC_URL = '/static/'
STATICFILES_DIRS =(
PROJECT_DIR+'/static',
##//don.t forget comma
)
TEMPLATE_DIRS = (
PROJECT_DIR+'/templates/',
)
proj/app/templates/filename.html
inside body
{% load staticfiles %}
//for image
img src="{% static "fb.png" %}" alt="image here"
//note that fb.png is at /home/project/app/static/fb.png
If fb.png was inside /home/project/app/static/image/fb.png then
img src="{% static "images/fb.png" %}" alt="image here"
I've had the hardest time figuring this out so I am making this post to explain as clearly as i can, what worked for me, to help someone else.
Let's say you have a project called project_name. and an app called app_name. your root directory should look like this:
/app_name
/project_name
manage.py
DEVELOPMENT.
while in development mode, your CSS and JS files should be inside ./app_name/static/app_name/..
however your images should be inside ./app_name/static/media/..
now add these to settings.py :
If this not already there, add
STATIC_URL = '/static/'
This tells Django where to find all the static files.
MEDIA_URL = '/media/'
This points Django to the folder where your images are, after it loads static. In this case it is /media/ because our images are in /static/media.
next, you should put this in the individual template where you need the image (I thought putting a single {% load static %} in the general layout.html template would suffice, it didn't):
{% load static %}
<img src="{% static image_name %}>
depending on how you set up your project, image_name could be the exact name of the image file like "image.jpg", a variable for an image field like user.image etc
lastly, go into the project_name urls.py (same folder as settings.py) and add this line to the end:
from django.conf import settings
from django.conf.urls.static import static
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
basically telling Django to use a work around so you can see use the images in development.
That is all. your project will now display images while you are writing and testing your code(development)
PRODUCTION.
When you want to deploy your project, there are some extra steps you need to take.
Because Django does not serve images as static files during production, you have to install a Middleware called Whitenoise.
http://whitenoise.evans.io/en/stable/#installation
pip install whitenoise
Then add the following to settings.py:
look for MIDDLEWARE and add just under django.middleware.security.SecrutiyMiddleware:
'whitenoise.middleware.WhiteNoiseMiddleware',
Next we have to define our paths, this is because in production Django will basically collect all the static files from all our apps and rearrange them in a single folder.
Add the following to settings.py:
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
This tells Django where to put static files when it collects them. In this case we are telling Django to put the files in the root folder. so after collectstatic runs our app would look like
/app_name
/project_name
/static
manage.py
Then add:
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
This tells django where to put files that a user who on our site uploads..
Next,we want to go up and change Debug to False.
Debug = False
Debug mode is used for testing in development, and in production you don't want your app displaying error codes and the names of files and lines where something went wrong. potential security threat. Once you turn debug mode to false, Django changes how it serves the static files. so ordinarily, if you were to run your app now, you won't see the images..
with these done, now you are ready for production. to test that everything is okay, you can run:
python manage.py collectstatic
(type yes if prompted)
Django will collect all the static files and arrange them as necessary. if you run your project now, with debug still turned off you should see your images. you can even now delete the individual static folders in app_name or any other apps you have, if you want because Django will not use them in production. Once debug is off, Django only uses static from the collected static folder.
You can now deploy your project
If you give the address of online image in your django project it will work.
that is working for me. You should take a shot.
Also check that the problem may not be due to path, but file name or extension. While failing to dislay an image added to base.html template, the error was found related to image file extension. If you are storing the image in jpeg format, use .jpg as the extension in the img tag
<img src="{% static 'logo.jpg' %}" alt="Logo">.
Just give a try copying static folder from base path to public_html folder.
cp -r static/ ~/public_html/
