Channels with django signals

I suggest you to change the user creation form to set the three attributes that you need (Is medical, is physuitherapist, is patient), so in the first form (when you create the user) you will have usernarme, password, Is_medical, is_physuitherapist, is_patient. Take a look -

Are django signals triggered within migrations?

Hi, I'm doing some data migrations (creating new model instances) in the migrations files and I have a couple of receivers on the `post_save` signal for the models I am creating instances. >From what I have seen, it seems that the signals are not triggered within the migration. Is that true?
