Get users goup name DRF

I'm trying to show user group name instead of it's id .
I have this serilizer class for user class and I used this User = auth.get_user_model() for user Model but it show NULL instead of theier name .. when i delete get_groups function i will see related groups id why ?

what is correct way to get all users group?

class UserSerializer(ModelSerializer):

    groups = SerializerMethodField()
    def get_groups(self, obj):
        return obj.groups.name

    class Meta:
        model = User
        fields = [
            'id',
            'username',
            'first_name',
            'last_name',
            'email',
            'date_joined',
            'last_login',
            'is_staff',
            'is_superuser',
            'is_active',
            'groups'
        ]

Try this,

class UserSerializer(ModelSerializer):

    def get_groups(self, obj):
        return obj.groups.values_list('name', flat=True)

    class Meta:
        model = User
        fields = [
            'id',
            'username',
            'first_name',
            'last_name',
            'email',
            'date_joined',
            'last_login',
            'is_staff',
            'is_superuser',
            'is_active',
            'groups'
        ]


This would return all grups related to paricular user as list

Example:

In [5]: user =User.objects.get(id=1)

In [6]: user.groups.values_list('name',flat=True)
Out[6]: ['grp_name_1', 'grp_name_2']

In [8]: user.groups.all()
Out[8]: [<Group: grp_name_1>, <Group: grp_name_2>]
