DRF Api-Key missing Attribute - django

Question

I am trying to use the DRF Api Key mechanism for authentication, after following the guide here:
https://florimondmanca.github.io/djangorestframework-api-key/guide/
I receive nothing but errors, does someone have a working example or see what i am doing wrong here?
Global Settings:
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': [
'rest_framework_api_key.permissions.HasAPIKey'
]
}
Tested in a class view also
class TestingApiKey(APIView):
permission_classes = [IsAuthenticated | HasAPIKey]
def post(self, request):```
3 sample curl requests:
Example 1
curl --location --request POST 'http://127.0.0.1:8000/api/test' \
--header 'Authorization: Api-Key TiJwEHau.MF4ov6E3iz3C9KNNRAGdryH1tXfkjz8r' \
--header 'Content-Type: application/json' \
--data-raw '{
"username" : "Testing",
"Password" : "Testing123"
}'
Example 2:
curl --location --request POST 'http://127.0.0.1:8000/api/test' \
--header 'Api-Key TiJwEHau.MF4ov6E3iz3C9KNNRAGdryH1tXfkjz8r' \
--header 'Content-Type: application/json' \
--data-raw '{
"username" : "Testing",
"Password" : "Testing123"
}'
Example 3
curl --location --request POST 'http://127.0.0.1:8000/api/test' \
--header 'X-Api-Key: Api-Key TiJwEHau.MF4ov6E3iz3C9KNNRAGdryH1tXfkjz8r' \
--header 'Content-Type: application/json' \
--data-raw '{
"username" : "Testing",
"Password" : "Testing123"
}'
Each test I carry out returns a 500 server error with the response:
'HasAPIKey' object has no attribute 'authenticate'
Anyone had this issue or understand why I would get this?

Answer 1

Ok, this has to do with adding global settings in the settings.py file.
I went back and commented out the following in the settings.py
"""
REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES': [,
'rest_framework_api_key.permissions.HasAPIKey'
]
}
"""
Once done I then added the following class object and everything worked fine.
permission_classes = [IsAuthenticated | HasAPIKey]
