Cannot upload image in django using filefield

Question

I am not able to upload image.

here is my models.py

class Post(models.Model):
    author = models.ForeignKey('auth.User')
    title = models.CharField(max_length=200)
    text = models.TextField()
    image = models.FileField(upload_to = 'post/static/images/' , null= True, blank= True)
    created_date = models.DateTimeField(default=timezone.now)
    published_date = models.DateTimeField(blank=True, null=True)

    def publish(self):
        self.published_date = timezone.now()
        self.save()

    def __str__(self):
        return self.title

the image is not getting uploaded to 'post/static/images/'

here is the template for uploading the image

    {% if post.media %}
    <img src="{{ post.image.url }}" class="img-responsive" />
    {% endif %}

Your code in template is not for uploading an image but to show an image. — doru

If you're using linux you should also check the upload folder permisions — doru

There are many problems with your code:

In your model - use the field for image uplaoding ImageField (to use ImageField you need to have installed Pillow):
```
image = models.ImageField(upload_to = 'images/' , null= True, blank= True)
```
(you will upload the images in a subfolder of the MEDIA_ROOT folder named images)
Also put the images in the media folder - you have to create one, in the settings.py folder add:
```
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media/')
```

To let django serve your media (only for development!) you have to add in your main (from your project directory not from your app folder) urls.py file:

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)

An example of a simple form to upload an image:

<form action="{% url upload_pic %}" method="post" enctype="multipart/form-data">{% csrf_token %}
    <input id="id_image" type="file" class="" name="image">
    <input type="submit" value="Submit" />
</form>

where url_upload_pic is the (function) view which should handle the upload of the image.

And I think a good thing too.

MEDIA_ROOT and STATIC_ROOT must have different values. Before STATIC_ROOT was introduced, it was common to rely or fallback on MEDIA_ROOT to also serve static files; however, since this can have serious security implications, there is a validation check to prevent it.

https://docs.djangoproject.com/en/1.11/ref/settings/#media-root

What you want to be doing (in development) is to follow this guide: https://docs.djangoproject.com/en/1.11/howto/static-files/#serving-files-uploaded-by-a-user-during-development

During development, you can serve user-uploaded media files from MEDIA_ROOT using the django.views.static.serve() view.

This is not suitable for production use! For some common deployment strategies, see Deploying static files.

For example, if your MEDIA_URL is defined as /media/, you can do this by adding the following snippet to your urls.py:

Basically, you updload the files to a place in MEDIA_ROOT and then tell django to treat them almost like static. But you don't directly upload to static.
