Building a blog-like app with django, should I normalize images outside of the blog entry's model?

Question

Just wondering because at the moment I am keeping the ImageFields as part of the BlogPost model. If I want to support the potential for 20 images, I have 20 such fields, when often almost 19 of them will never be used. But if I normalize them into a separate model, it's not as intuitive to add images to a post in the admin page, since you have to select the post from a drop down for each image you wish to add, over and over.

Is there a better way to solve this?

Answer 1

You definitely should create separate model for images.

To edit the images in the admin site you should use inlines. Read the docs here: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#inlinemodeladmin-objects

Answer 2

There are already-built image-handling modules for django. For example:
