Foreign Key to a user Custom Model

[nicolasq92]

Hi.

I have a problem.

I want to make a relationship many to one to my model user with company.

I have created my business model, and my user model with a one-to-one relationship with the original User model.

model.py

from django.db import models
from django.contrib.auth.models import User


class Empresa(models.Model):
    NombreEmpresa = models.CharField(max_length=120)

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    company_name = models.ForeignKey(Empresa)

serializers.py

class EmpresaSerializer(serializers.Serializer):

    class Meta:
        model = Empresa
        field = ('id','nombreEmpresa')

class UserSerializer(UserDetailsSerializer):

    company_name = serializers.CharField(source="userprofile.company_name")
    # company_name = serializers.ModelSerializer(EmpresaSerializer(many=False, read_only=True))

    class Meta(UserDetailsSerializer.Meta):
        fields = UserDetailsSerializer.Meta.fields + ('company_name',)

    def update(self, instance, validated_data):
        profile_data = validated_data.pop('userprofile', {})
        company_name = profile_data.get('company_name')

        instance = super(UserSerializer, self).update(instance, validated_data)

        profile = instance.userprofile
        if profile_data and company_name:
            profile.save()
        return instance

The point is that I do not understand how to show the foreign key of the company when I log in or when I consult the endpoint / rest-auth / user

If there is another way to assign multiple users to another model, I would appreciate it if you would guide me ..

Thank you

I await your comments.
