是否可以获取Django的“ changed_data”列表中包含的项的值？

Question

I have the following code in my Django application:

if 'book' in authorForm.changed_data:
   #Do something here...

I realize Django can tell me which values have changed in my form by utilizing the "changed_data" list object, but I'd like to know the new values of the fields that have changed.

Any thoughts?

Answer 1

Hmm... Try this:

if authorForm.is_valid() and 'book' in authorForm.changed_data:
    new_value = authorForm.cleaned_data['book']

Answer 2

我最初的问题的简短答案是“否”。
