Inlines are very useful for creating/updating related objects at the same
time. However, sometimes you only want to create/update one of the
objects instead of both. For example, when creating a User you may not
want to add the associated content in a related profile model, but want to
do so later.
The current implementation defines and instantiates the inlines when a
admin.ModelAdmin class is instantiated, but does not allow
addition/removal of more inlines anywhere(or anytime) else.
I propose two functions register_inline_instance() and
unregister_inline_instance() that allow inlines to be added and removed
from a model on the fly.
Example usage:
{{{
class UserAdmin(admin.ModelAdmin):
inlines = [StudentInline,]
...
def add_view(self, request, form_url='', extra_context=None):
self.unregister_inline_instance(StudentInline)
return super(UserAdmin, self).add_view(request, form_url,
extra_context)
def change_view(self, request, form_url='', extra_context=None):
self.register_inline_instance(StudentInline)
return super(UserAdmin, self).change_view(request, form_url,
extra_context)
...
}}}
