django-signals

I use Django 1.7 migrations, and in particular, want to populate a newly-created database with initial data. Thus, I use a data migration for this. It looks like this: def populate_with_initial_data(apps, schema_editor): User = apps.get_model("auth", "User") new_user = User.objects.create(username="nobody") class Migration(migrations.Migration): ... operations = [ migrations.RunPython(populate_with_initial_data), ] At the same time, I want to have an instance of the UserDetails model for every new user: @receiver(signals.post_save, sender=django.contrib.auth.models.User) def add_user_details

I read the django docs about signals and wrote this piece of code for my model Car : @receiver(request_finished) def signal_callback(sender, **kwargs): print 'Save Signal received' @receiver(post_save, sender=Car) def signal_handler(sender, **kwargs): pass request_finished(signal_callback, sender=car, dispatch_url="Unique save id") But the problem is, that when I fire up my server, and just open up the admin, I get a lot of 'Save Signal received' in my terminal.

Is it allowed/ok to change the Collection within the signal callback? Can I use the signal also for

I created a 'profile' model (with a 1-to-1 relationship to the User model) as described on Extending the existing user model . The profile model has an optional many-to-one relationship to another model: class Profile(models.Model): user = models.OneToOneField(User, primary_key=True) account = models.ForeignKey(Account, blank=True, null=True, on_delete=models.SET_NULL) As documented there, I also created an inline admin: class ProfileInline(admin.StackedInline): model = Profile can_delete = False verbose_name_plural = 'profiles' # UserAdmin and unregister()/register() calls omitted, they are

I am using Django-allauth for my login/signup related stuff, so when a user signs up(first time) into my site, I am redirecting him to /thanks/ page by defining below setting in settings.py file LOGIN_REDIRECT_URL = '/thanks/' But when the user tried to log in for the next time(if already registered) I should redirect him to '/dashboard/' URL So tried to alter that with Django-allauth signals like below which is not working at all @receiver(allauth.account.signals.user_logged_in) def registered_user_login(sender, **kwargs): instance = User.objects.get_by_natural_key(kwargs['user']) print
