问题 All, I have researched this for a couple of days, and can't quite seem to find what I'm looking for. I am well aware of using the following to disable a field in a Django form: self.fields['author'].disabled = True The above will disable a field entirely.

问题 I am currently working on a project that would take in a users information and store it. My problem is I keep running into this NOT NULL constraint failed with the user id error. I believe this comes from having a null user when the form is trying to save, but don't know what I could do to fix it.
