Unable to join static file to root directory in Django

To join the static file in Django,
STATIC_URL = "os.path.join(BASE_DIR, '/static/')"
print("static file : ", (os.path.join(BASE_DIR, '/static')), )
This is producing :
static file : C:/static
But in the same document I had joined template folder:
print("Path is : ", os.path.join(BASE_DIR, 'myproject/template'))
Which produces this: Path is : C:\Users\user\Desktop\django\myproject\myproject/template
Is this the reason Django is producing this error:
ERRORS:
?: (urls.E006) The STATIC_URL setting must end with a slash.
Could you please advise how can i resolve this error?

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static/')
STATIC_URL is the path on your website url.
STATIC_ROOT is the path on your server where static files are located.

Django: ValueError: Missing staticfiles manifest entry for 'jquery.twbsPaginationAlt.min.js'

Before marking as duplicate, note that I've checked all the similar questions that have been asked and it has not fixed my problem. I've deployed my Django App on Heroku in in one template where I reference a min.js file, it throws this error in question.
My basic directory structure is this:
myapp
mysite
dictionary
static
jquery.twbsPaginationAlt.min.js
staticfiles
settings.py:
STATIC_URL = '/static/'
# STATIC_ROOT = [os.path.join(BASE_DIR, 'staticfiles'), os.path.join(BASE_DIR, 'static/fonts')]
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
if DEBUG:
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'mysite/static'), os.path.join(BASE_DIR, 'static/')]
import django_heroku
# handles staticfiles, database url, and secret key, can be overwritten as needed
django_heroku.settings(locals(), secret_key=False, logging=False)
So originally if STATICFILES_DIRS had any value, I would get an error of FileNotFoundError: [Errno 2] No such file or directory: '/tmp/build_6f3eb879/mysite/static' when running collectstatic on heroku. However, if it is not set, than the fonts I have in my dev environment do not load in properly (I also have fonts inside the base level static folder).
This is how I reference the js file in my problem template, it works fine on dev:
<script src='{% static 'jquery.twbsPaginationAlt.min.js' %}'></script>
For convenience, here is what django-heroku does in terms of staticfiles:
logger.info('Applying Heroku Staticfiles configuration to Django settings.')
config['STATIC_ROOT'] = os.path.join(config['BASE_DIR'], 'staticfiles')
config['STATIC_URL'] = '/static/'
# Ensure STATIC_ROOT exists.
os.makedirs(config['STATIC_ROOT'], exist_ok=True)
# Insert Whitenoise Middleware.
try:
config['MIDDLEWARE_CLASSES'] = tuple(['whitenoise.middleware.WhiteNoiseMiddleware'] + list(config['MIDDLEWARE_CLASSES']))
except KeyError:
config['MIDDLEWARE'] = tuple(['whitenoise.middleware.WhiteNoiseMiddleware'] + list(config['MIDDLEWARE']))
# Enable GZip.
config['STATICFILES_STORAGE'] = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
(from https://github.com/heroku/django-heroku/blob/master/django_heroku/core.py)
EDIT:
In order to fix this I had to stop using django heroku, change my STATICFILES_STORAGE variable to whitenoise.storage.CompressedStaticFilesStorage , and reorganize where I kept some of my static files by checking the logs to see what path the GET requests were going to. It seems whitenoise is pretty imperfect based off the other stackoverflow posts I've seen, it consistently misses 'static/' files in the root directory. Additionally since Django relies a lot on the 'static' keyword in templates, and this is not available in .css files, the only way to resolve getting static files into a css file (for fonts for example), is trial and error of testing different paths.

This line looks very odd to me and may be the source of the problem:
if DEBUG:
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'mysite/static'), os.path.join(BASE_DIR, 'static/')]
Why are you only defining your STATICFILES_DIRS in debug mode? You'll need those defined in production too.

Saving Image File in particular directory in Django Rest Framework

I am using Python PIL library in Django Rest Framework for building qr code and saving it to static directory.
def generate_qr(self, name):
qr = qrcode.QRCode(
version=1,
error_correction=qrcode.constants.ERROR_CORRECT_M,
box_size=15,
border=5
)
qr.add_data(name)
qr.make(fit=True)
img = qr.make_image(fill='black', back_color='white')
img.save(settings.STATIC_ROOT+"/asset-tags/name.png")
return(name+ '.png')
settings.py for media and static urls:
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
MEDIA_URL = "/mediafiles/"
MEDIA_ROOT = os.path.join(BASE_DIR, "mediafiles")
But while saving it throws an error saying /usr/app/static/name.png : no file or directory.
I am creating new file so how can it find the image in given folder.
Any Help will be appreciated. Thanks.

The qrcode package or Pillow package won't create a directory if it doesn't exist. So, as per your settings, the STATIC_ROOT is located at /staticfiles and make sure that the directory named staticfiles (and it's sub-directories) exists before runs your script.
In other words, the statement img.save(settings.STATIC_ROOT+"/asset-tags/name.png") supposed to be save the QR code image under this path /staticfiles/asset-tags/name.png and make sure the directory /staticfiles/asset-tags/ exists in your project path.
NOTE: Use settings.MEDIA_ROOT instead of settings.STATIC_ROOT would be more appropriate.

django static_root understanding - IOError - ??

i am trying to use some image in my views.py, i did this,
from django.conf import settings
image = settings.STATIC_ROOT + "images/test.png"
fp = open(image, 'rb')
but it is saying:
IOError at /
(2, 'No such file or directory')
in my settings.py, i have:
STATIC_ROOT = os.path.join(PROJECT_PATH, "static")
STATIC_URL = '/static/'
what do i miss here ? STATICFILES_DIRS is empty but in templates, i has been working till now, but now i want to get image in my views.py.

You could try:
from django.contrib.staticfiles.views import serve
serve(request, 'images/test.png')
If memory serves me correct tho this will only work if debug is true.
But it sounds like its not finding the path, to find te project path...
Print(normpath(join(dirname(__file__), '..')))
This should help you identify and correct the problem.

django ImageField not uploading the file

So i've been googling this issue for the past hour and can't come up with a solution. Basically this is it: in my model.py i have a class that has this
class Case(models.Model):
zoomOutImage = models.ImageField('Label', upload_to="zoomOutImage")
and in my settings.py i have my media URL/ROOT set up like this
MEDIA_ROOT = os.path.join(os.path.abspath(''),'app/static/ds/')
MEDIA_URL = '/static/ds/'
which from the webserver should serve out like this:
http://127.0.0.1:8000/static/ds/zoomOutImage/actinic_granuloma_3.jpg
I've installed PIL (inside virtualENV) and there are no errors in uploading, the only issue is when i try uploading the file via the admin panel nothing happens. No errors nothing. The file just simply doesn't get uploaded to the zoomOutImage folder by the development server. Can anyone point me towards why?

I guess your file is in a subdir of your root, subdir named 'zoomOutImage'. Or even a file called like that in the root. I remember putting a function call in the upload to string. That function creates a path and filename, using os.join and the filename from the instance. Doing this by head, no example code available right now. But must be able to google this.
Look here https://stackoverflow.com/questions/1190697/django-filefield-with-upload-to-determined-at-runtime
And by the way, I totally disagree with your answer, you should NEVER use absolute paths in your settings! See this answer use css in django 1.4 development for how to use the correct settings and refer to your Project PATH
EDIT (after reading your own answer)
Guess you are missing this first step:
this is the path to your settings.py file:
SETTINGS_DIR = os.path.dirname(os.path.realpath(__file__))
and than this is the path to your project dir: (I Am using buildout, so call it buildout, but it's the root of your project):
BUILDOUT_DIR = os.path.abspath(os.path.join(SETTINGS_DIR, '..'))
and from there on you can define everything you want:
STATIC_ROOT = os.path.join(BUILDOUT_DIR, 'var', 'static')
STATIC_URL = '/static_media/'
MEDIA_ROOT = os.path.join(BUILDOUT_DIR, 'var', 'media')
MEDIA_URL = '/media/'
and in your template file refer to the image like:
<img src="{{MEDIA_URL}}{{ case.zoomOutImage }}" width="100%">
when your object given to the template is called case
about your question of the urls.
you should add this:
if settings.DEBUG:
urlpatterns += patterns('',
(r'', include('staticfiles.urls')),
)
and see the link above to the question about using css, it's the same problem, but there for finding the css files during development. It's all about the static file places.

import os
# get abspath
def rel(*x):
return os.path.join(os.path.abspath(os.path.dirname(__file__)), *x)
MEDIA_ROOT = rel('media')
MEDIA_URL = '/media/'
STATIC_URL = '/static/'
STATIC_ROOT = '' #if only your static files are in project folder
STATICFILES_DIRS = ( rel('static'),) #if only your static files are in project folder
use this settings, and everything will work

so i finally solved my problem. For anyone having this issue in the future do the following:
if you're trying to serve static media files locally on the development server use absolute paths for MEDIA_ROOT and MEDIA_URL.
