  name = models.CharField(max_length=40, default=\'         


        

Answer 1

Please check...

your model.py

class Account(AbstractBaseUser):
  email = models.EmailField(unique=True)
  username = models.CharField(max_length=40, unique=True)
  first_name = models.CharField(max_length=40, blank=True)
  last_name = models.CharField(max_length=40, blank=True)
  tagline = models.CharField(max_length=140, blank=True)
  is_admin = models.BooleanField(default=False)
  created_at = models.DateTimeField(auto_now_add=True)
  updated_at = models.DateTimeField(auto_now=True)
  objects = AccountManager()
  USERNAME_FIELD = 'email'
  REQUIRED_FIELDS = ['username']


class Project(models.Model):
      author = models.ManyToManyField(Account)
      name = models.CharField(max_length=40, default='NewBook')

your serializer.py

class ProjectSerializer(serializers.ModelSerializer):
    author = AccountSerializer(read_only=True, required=False)

    class Meta:
        model = Project
        fields = ('id', 'author', 'name')
        read_only_fields = ('id')

    def get_validation_exclusions(self, *args, **kwargs):
        exclusions = super(ProjectSerializer, self).get_validation_exclusions()
        return exclusions + ['author']

and finally your view.py is

class ProjectViewSet(viewsets.ModelViewSet):
  queryset = Project.objects.order_by('-name')
  serializer_class = ProjectSerializer

  def perform_create(self, serializer):
    instance = serializer.save(author=self.request.user)
    return super(ProjectViewSet, self).perform_create(serializer)
