- Customization
- Remember that you can add any method to your models, and use that method in your templates. If you have a method on the Post class called “otherAuthorPosts” that returns all of the other posts by this posting’s author, you can reference it as “post.otherAuthorPosts”. You can also provide any variable—including classes, lists, and dictionaries—to the context that your view creates, and pass it to your…

- Modifying models

- Multiple Input Fields with multiple inheritance
-
We needed to display one TextField as either a TextInput or a Textarea, depending on the value in the field. Multiple inheritance makes it easy, if a bit wonky.
- Django tutorial mostly ready
-
My long-promised Django tutorial is pretty much ready. It’s still designed around an in-person tutorial, but you should be able to get started using it even if you’re on your own.
