I am making a website using html, css, flask and jinja2.
I have a page working on a flask server, the buttons and labels etc. are displayed, but the css stylesheet I have is not loaded in.
How would I link a stylesheet to a jinja2 template. I have looked around on the internet but cannot find out how.
Here is the css stylesheet link; should I change this, or the python code?
<link rel="stylesheet" type="text/css" href="styles.css">
here is my flask code:
#app.route('/')
def resultstemplate():
return render_template('questions.html', head='Welcome!')
here are the locations of the files:
/python-code.py
/templates/template.html
/templates/styles.css
All public files (the ones that are not processed, like templates or python files) should be placed into dedicated static folders. By default, Jinja2 has one static folder called static.
This should fix your problem:
Move /templates/styles.css to /static/styles.css
Update your code with following code, that will be translated into correct file location:
<link rel="stylesheet" href="{{ url_for('static', filename='styles.css') }}">
More info on static files in Jinja2 is here.
<link rel="stylesheet" type="text/css" href="styles.css">
href value must be within quotes.
make sure the file name and path are proper
OR try the below
<link rel="stylesheet" href="{{ url_for('static', filename='styles.css') }}"/>
The order of handler might cause the problems:
url: /stylesheets static_dir: stylesheets
url: /.* script: helloworld.application
will work instead of
url: /.* script: helloworld.application
url: /stylesheets static_dir: stylesheets
you should use the super() block style .
see the code below:
{% block style %}
{{ super() }}
<link rel="stylesheet" href="{{ url_for('static', filename='css/styles.css') }}"/>
{% endblock %}
Tried almost every solution on Stack Overflow. It only worked for me when I placed the static folder in the same directory as my run.py file.
I changed my folder structure from:
app/
views
static
templates
run.py
To:
app/
views
templates
static
run.py
I guess moving the run.py instead would work too. Have a look at this Jinja Templating Tutorial for extra info. Not sure why I had to change the structure for it to work though.
To add to what's been said here, be sure to update Jinja2 to v2.10, as lesser versions seem to cause this same bug. Cheers!

I know this is a duplicate question, but I was trying to add a favicon.ico file to my site on localhost:8000 made with Django. The favicon exists on templates\articles (in an app called articles), and I've tried everything on stackoverflow, youtube, and used realfavicongenerator.net, but nothing works. Do I have to define the Django URL/view for the ICO file, as localhost:8000/favicon.ico brings up error? Here's my (simplified) code by the way:
<title>Newsreed | Articles</title>
<link rel="shortcut icon" type = 'image/x-icon' href="favicon.ico">
What should I do, because I've been struggling with it for several days now and tere has been no solution on anything.
I like to use:
https://www.favicon-generator.org/
They let you upload an image to use and it will output a directory with all scaled versions of the image for all manner of devices your page could be viewed on including the html that you will need to copy and paste.
Fairly sure the syntax for the href should be: href="{% static 'imgs/favicon.ico' %}
Best way to have a favicon on every page on your site is to link it to the base.html with href="{% static 'articles/favicon.ico' %}. Mind that you need to put {% load static %} in the template too.
Code standard favicon links at the top of your template or base.html and make sure the icons are there in the directory/s :
{% load staticfiles %}
<head>
<link rel="shortcut icon" href="{% static "img/favicon.ico" %}">
<link rel="icon" href="{% static "img/animated_favicon1.gif" %}">
You can use favicon-generator.org to create new favicons.
To practise my Django skills, I want to try to host a game on my website. The game was made in Unity and packaged using WebGL.
I used the index.html created by WebGL as a Django template and created the URL path and view in the relevant locations. WebGL creates two folders, Build and TemplateData that are referenced in index.html.
I have tried putting these folders in with the html templates, and on every level in my Django folder structure.
The outcome is the same wherever I put the folders. The GET command is sent but a "Not Found: /TemplateData/filename...." is shown for a few files
Does anyone know how to see where the GET command is looking, or just where the folders should go?
Thanks,
Sophie
After some more messing about I found that you can just wham everything into the static folder and then reference it in index.html the same way you pick up css files in base.html
{% load static %}
.....some more code
<script>
var gameInstance = UnityLoader.instantiate("gameContainer", "{% static
'Build/Juno_WebGL.json' %}", {onProgress: UnityProgress});
</script>
Do this for every reference to the files in index.html
I ran into this same issue recently and came across this thread. Here was my solution for anyone who may come across this in the future.
take the index.html file generated and put it in your templates folder, create a link through to this template using the standard django, url, view, template flow e.g:
urls.py:
urlpatterns = [
path('', views.home, name='home'),
path('unity/', views.unity, name='unity'),
]
views.py:
def unity(request):
return render(request, template_name='mainapp/unity.html')
Take your WebGL build files and put them somewhere in your static folder. Finally edit your index.html so that it includes {% load static %} and look for any href's in the file and point these to your static folder, do the same for any scripts. E.g. My Unity builds WebGL application had a 'var buildUrl = "Build";' line which I had to point towards my static folder.
Example:
<!--block content etc.. -->
{% load static %}
<html lang="en-us">
<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Unity WebGL Player | UnityApp</title>
<link rel="shortcut icon" href="{% static 'unity/TemplateData/favicon.ico' %}">
<link rel="stylesheet" href="{% static 'unity/TemplateData/style.css' %}">
</head>
<!-- etc.. -->
<body>
<script>
var buildUrl = "../static/unity/Build";
var loaderUrl = buildUrl + "/Unity App.loader.js";
// etc..
</script>
</body>
</html>
I get the templates files, I divide them to static files and templates files.
As you know I can not correct open the html in browser now, because thier path all changed.
I can in the templates files to change every link or script and image path one by one, but its a trouble things, takes our away many time.
Is there a simple way to do that?
EDIT
I changed to this, but not works for me:
{% load static %}
<!--<link rel="stylesheet" href="../static/css/default.min.css?t=227" />-->
<link rel="stylesheet" href="{% static 'css/default.min.css?t=227' %}" />
in the browser debugger, it become this:
<link rel="stylesheet" href="/static/css/default.min.css%3Ft%3D227">
If I understand the question correctly, you need to use the {% static %} tag in the templates, like this:
{% load static %}
...
<img src="{% static 'images/favicon.png' %}">
For more information, check my detailed explanation.
I followed this tutorial for develop templates with flask http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-ii-templates
My file tree is the next one:
/static
/js
bootstrap.min.js
jquery_1.11.3.js
/css
bootstrap.min.css
/images
/templates
index.html
/python_venv
server.py
server.py code:
#app.route('/subdomain/')
def getPrevisionPoblacion():
return render_template('index.html')
And css link inside index.html code is the following:
<script src="/static/js/bootstrap.min.js"></script>
<link rel="stylesheet" href="/static/css/bootstrap.min.css"/>
<script src="/static/js/jquery_1.11.3.js"></script>
nginx config:
location /subdomain/{
root /apps/subdomain/static;
uwsgi_pass unix:///tmp/subdomain.sock;
include uwsgi_params;
}
When I check it on Chrome, the index didn't load the CSS files. I checked the network with Developer's tools and the error is 404.
I tried also similar code that i saw on this unresolved question without success
Inline CSS background:url() not working in Jinja2 template
Any help about this ?
The problem was the server.
I had to serve static folder for flask template can load css.
I wrote in nginx config file the next:
location /subdomain/static)/ {
root /opt/apps/content_folder/static;
}
I don't use url_for() function y wrote the resource's URL as:
static/css/my_css_template.css
Finally check out #app.route() inside the file that render the template was correct then flask template could access to css, images and js.
if you put the static files directly under the /static folder, this should work
<link rel=stylesheet type=text/css href="{{ url_for('static', filename='bootstrap.min.css') }}">
if you do not want that, follow the instructions in this questions approved answer,
Link to Flask static files with url_for
I've searched for answer for this question, but i havent found any solution for my problem. I want to link css to my project, but just cant handle how STATIC_URL work
<head>
{% load static from staticfiles %}
<link rel="stylesheet" type="text/css" href="{% static "css/style.css" %}">
</head>
it's to much code to post here so here are the links:
settings.py: http://pastebin.com/9Bsg3u1h
And I render with context_instance=RequestContext(request) parameter of course.
I got files structure like this:
Django_project
...
appname
templates
static
I tried also to place static directory in many project, in appname, and even in templates.
Can someone explain me how should it look for my project?
Use the builtin static, not static from staticfiles:
<head>
{% load static %}
<link rel="stylesheet" type="text/css" href="{% static "css/style.css" %}">
</head>
https://docs.djangoproject.com/en/dev/ref/templates/builtins/#static
Django ships with a static template tag. You can use this regardless if you’re using RequestContext or not.
Note
The staticfiles contrib app also ships with a static template tag which uses staticfiles' STATICFILES_STORAGE to build the URL of the given path. Use that instead if you have an advanced use case such as using a cloud service to serve static files...
