Inlines, Uneditable Fields, and ModelAdmin Methods

Using inlines

Now, you will focus on adding some functionalities to change_view pages (page to create or edit a model instance). Sometimes, it can be useful when editing a model to see or add foreign key values too. For example, you could say that when editing an author, we would like to add or see his questions.

To do this, you will use the inlines keyword:

class QuestionInline(admin.TabularInline):
	model = Question

class AuthorAdmin(admin.ModelAdmin):
...
	inlines = [QuestionInline,]
...

First, you need to define a new class QuestionInline which inherits from admin.TabularInline or admin.StackedInline, and then, in your AuthorAdmin, you will specify the inlines class name with inlines=[QuestionInline,].
