TypeError: __init__() got an unexpected keyword argument 'permissions'

I am getting this error when I add a permissions argument in the Serializer. Heres the stack trace:

Heres my serializer serializer.py

from serializer_permissions import serializers as customSerializers
...
class CompanyProfileSerializer(customSerializers.ModelSerializer):
    company_phone_numbers = CompanyPhoneNumberSerializer(many=True, required=False, permissions=(permissions.IsAuthenticatedOrReadOnly, ))
    company_addresses = CompanyAddressSerializer(many=True, required=False, permissions=(permissions.IsAuthenticated, ))
   email_address = customSerializers.EmailField(permissions=(permissions.IsAuthenticated, ))
    class Meta:
        model = Company
        exclude = ["created_date", "created_by", "modified_date", "modified_by"]

Also, I could take up this issue if you'd like me to :)

The __init__ call to serializer_permissions.serializers.ModelSerializer is missing in the stack trace.

 File "C:\Users\Clearspace User\Documents\Programming\QCS\qcs-v2-backend\apps\company\serializers.py", line 21, in CompanyProfileSerializer
   company_phone_numbers = CompanyPhoneNumberSerializer(many=True, required=False, permissions=(permissions.IsAuthenticatedOrReadOnly, ))
 File "C:\Users\Clearspace User\Documents\Programming\QCS\qcs-v2-backend\venv\lib\site-packages\rest_framework\serializers.py", line 121, in __new__
   return cls.many_init(*args, **kwargs)
 File "C:\Users\Clearspace User\Documents\Programming\QCS\qcs-v2-backend\venv\lib\site-packages\rest_framework\serializers.py", line 146, in many_init
   child_serializer = cls(*args, **kwargs)
 File "C:\Users\Clearspace User\Documents\Programming\QCS\qcs-v2-backend\venv\lib\site-packages\rest_framework\serializers.py", line 115, in __init__
   super().__init__(**kwargs)

This should be:

  File "/opt/virtualenvs/testenv/lib/python3.6/site-packages/mytestapp/serializers.py", line 42, in ResultListSerializer
    submissions = ResultSerializer(many=True, help_text="Liste der abzufragenden Submissions", permissions=("asda",))
  File "/opt/virtualenvs/testenv/lib/python3.6/site-packages/rest_framework/serializers.py", line 121, in __new__
    return cls.many_init(*args, **kwargs)
  File "/opt/virtualenvs/testenv/lib/python3.6/site-packages/serializer_permissions/serializers.py", line 65, in many_init
    child_serializer = cls(*args, **kwargs)
  File "/opt/virtualenvs/testenv/lib/python3.6/site-packages/serializer_permissions/mixins.py", line 7, in __init__
    super().__init__(*args, **kwargs)
  File "/opt/virtualenvs/testenv/lib/python3.6/site-packages/rest_framework/serializers.py", line 115, in __init__
    super().__init__(**kwargs)

Can you check, if you are using serializer_permissions.serializers.ModelSerializer as base class for CompanyPhoneNumberSerializer

Which django version and restframework version do you use?

If this is an issue in my library, I would be glad, if you provide a pull request :smiley:

[manfred-kaiser]

have you solved the problem?
