How to display images from an ImageField in Django? - django

Question

Before I explain, I have a question. I am making a blog and the posts have a heading image. I upload this image using admin when I create a post for my blog. Is this image 'static' or 'media'?
Anyway, I have my project set up as follows:
mysite is my project, blog is my app. I have a folder named static inside blog. Inside this static folder are four more folders- css, images, fonts, js.
In settings.py, I have this set up:
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
My models.py looks like this:
class Post(models.Model):
...
header_image = models.ImageField('article_header_image', upload_to = 'blog/static/images/articleimages')
Now when I try to load this image in a template, it doesn't show up.
I am doing this the following way:
{% for post in posts %}
<img src="{{post.header_image.url}}">
{% endfor %}
Another thing, how can I use the upload_to argument to upload images into the app's static folder without explicitly stating it? I think thats where the issue is. If I use upload_to = 'static/images/articleimages', a new static folder is created in the mysite folder containing manage.py.
Any help is greatly appreciated!

You can import the STATIC_ROOT from settings file, and use that to biuld the path. In addition to that, you can use a callable, and build path there instead:
import os.path
from django.conf import settings
def generate_upload_path(instance, filename):
return os.path.join(settings.STATIC_ROOT, 'images/articleimages/')
class Post(models.Model):
...
header_image = models.ImageField('article_header_image', upload_to = generate_upload_path)
Ok, if you want to upload images to static directory of your app, you can use __path__ attribute of your app:
import blog
def generate_upload_path(instance, filename):
return os.path.join(blog.__path__, 'static/images/articleimages/')
