python 3.x - Force User to Provide Profile Before Saving in Django Admin -

am trying force user provide profile before saved django admin. here profile model

class userprofile(models.model):      user=models.onetoonefield(auth_user_model,related_name='profile',primary_key=true)     #other fields      def get_user_info(user):         return userprofile.objects.get(user=user)     @receiver(post_save, sender=auth_user_model)     def create_profile_for_new_user(sender, created, instance, **kwargs):         if created:             profile = userprofile(user=instance)             profile.save() 

am using authtools user profile sender auth_user_model. if add new user within admin,they saved if have not provided or filled in profile. want prevent them being saved until fill in profile fields. insights on how this? here admin.py

the best way create custom middleware , check, if logged in user has filled out profile. if not, middleware redirect user view, can fill out profile.

example:

class profilemiddleware(middlewaremixin):     def __init__(self, get_response=none):         self.get_response = get_response      def process_view(self, request, view_func, view_args, view_kwargs):         if not request.user.profile:             return httpresponseredirect(reverse('create-profile'))         return none 

haven't tested code, should started. it's cleanest way of doing , force user fill out profile, otherwise cannot open page on website.

hope helps.
