Django 2.2 Media files

[Michał Ratajczak]

Hi, i'm new in Django, I'm trying to configure media files correctly.

That's in my model.py:

class Question(models.Model):
    description = models.CharField(max_length=200)
    image = models.ImageField(upload_to='media/', null=True, blank=True)

in settings.py:

STATIC_URL = '/static/'
MEDIA_URL = '/media/'

ENV_PATH = os.path.abspath(os.path.dirname(__file__))
STATIC_ROOT = os.path.join(ENV_PATH, '../public/static/')
MEDIA_ROOT = os.path.join(ENV_PATH, '../public/media/')

in urls.py:

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('barber.urls'))
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

in view.py:

def index(request):
    images = Question.objects.values('image')
    template = loader.get_template('barber/index.html')
    context = {
            'images': images
        }
    return HttpResponse(template.render(context, request))

I'am adding an image via admin site and next i render in template. Url for image is "media/image.png" bit file is in .../media/media/image.png, so i can't understand it. Can anyone help me ?

Remove the upload_to in the model.

Since you already configured static folder called media in settings.py, if you specifify upload_to='/media', Django will create a folder 'media' inside the media folder.

I just find it really useful to save it in Google cloud

I Remove upload_to and it still wasn't working and next i did in my template.html:

{% get_media_prefix as STATIC_PREFIX %} <- i added this line because {{ item.image }} returns only 'image.jpg'. Now a url is correct :)

{% for item in images %}
                    <img class="container-images-image" src={{ STATIC_PREFIX }}{{ item.image }}/>
                {% endfor %}

Hi.

What you did is correct and expected.

Upload_to is relative path to MEDIA_ROOT in case of normal file upload backend. There are many others like S3.

Now MEDIA_URL is absolute path of web server which points to MEDIA_ROOT. In development you can use static file serving trick like you did.

Now when getting url in template you should use something like {{ image.url }} which should render correct absolute url to your  uploaded file.

HTH.

You need {{ item.image.url }} on your template since you are iterating through the context you passed in views. I'm sure you did something like this in views 

def home(request)

    images = Your_model.objects.all()

    context = {'images': images}

    return render(request, 'path_to/your/template', context)
