Django rest framework authentication

Question

I would like create authentication in Django. I'm trying to do everything according to this . Unfortunately, at this moment I have two problems. Firstly, when I try to add from rest_framework.authtoken import views I have conflict with from companies import views . I need views from authtoken to url(r'^api-token-auth/', views.obtain_auth_token) . Secondly, when I use /api-token-auth/ My problem is that I can log in only superuser, for other users in my database I get response - "Unable to log in with provided credentials."

Answer 1

Use as to remove the conflicts.

from companies import views as companies_views
from rest_framework.authtoken import views as rest_auth_views

and use this in urls url(r'^api-token-auth/', rest_auth_views.obtain_auth_token)

Provide details is not enough to debug what cause authentication. Can you provide more code about your token based authentication.

Update:

After communicating with OP. He created the user using UserSerializer and that saving the password as plain text. And authentication not works.

class UserSerializer(serializers.ModelSerializer): 

    class Meta: 
        model = User 

        fields = '__all__'`

    def create(self, validated_data):
        user = User.objects.create_user(**validated_data)
        return user

Answer 2

You need to include TokenAuthentication to your DEFAULT_AUTHENTICATION_CLASSES in your settings.py .

From the docs,

To use the TokenAuthentication scheme you'll need to configure the authentication classes to include TokenAuthentication.

So change your settings.py like this,

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.TokenAuthentication',
    )
}
