I can't distinguish roles with my implementation in DRF+Angular

Question

I've made an implementation of a login system using django as backend and angular as frontend.

In the backend the authentication is implemented via the view associated to auth/signup

from django.contrib import admin
from django.urls import include, path
from rest_framework import routers

from shopping.views import listatodoseventos

from rest_framework_jwt.views import obtain_jwt_token, refresh_jwt_token

urlpatterns = [
    path('admin/', admin.site.urls),
    path('api-auth/', include('rest_framework.urls')),
    path('events',listatodoseventos),
    path('auth/', include('rest_auth.urls')),
    path('auth/signup/', include('rest_auth.registration.urls')),
    path('auth/refresh-token/', refresh_jwt_token) 
]

In the frontend is done by this method

  signup(username:string, email:string, password1:string, password2:string){
    //todo
    return this.http.post(
      this.apiRoot.concat('signup/'),
      {username, email, password1, password2}
    ).pipe(
      tap(response=>this.setSession(response)),
      shareReplay()
    );
  }

It generates me these tables related with users.
I want to associate each user with a role.
But I don't know how to do that cause I don't know how to create entries in auth_user_groups

link to the tables

Answer 1

What i did to associate a user with a specific role was to create groups and to send the user with the groups to my angular application.

There are two solution to your problem.

First would be to create groups: Here is how i created a group and added a user to it.

from django.contrib.auth.models import Group,

    
group, group_has_been_created = Group.objects.get_or_create(name=PRODUCT_MANAGER_GROUP_NAME)
group.user_set.add(product_manager_user)

After having a group and a associated user you can create a response to the angular application.

And another way would be to create profiles and link then to your user.

class UserProfile(models.Model):
    user = models.OneToOneField(
        User, on_delete=CASCADE, related_name="user_profile", verbose_name=_("user")
    )

Here is a good article, which i also used :D. https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html

Hope this helps.
