How to call other methods in a class in django when self is not supplied as an argument-CodePudding

I come from PHP/Laravel Background where for calling methods or accessing properties within a class ,use of $this keyword is sufficient.In python3/Django4.0.6 i have to use request as first parameter to capture the request body for eg.

class CustomAuth:

      def verifyToken(token):
          pass

      def login(request):
          data = request.body
          # how do i call verifyToken?
          # if i use self as first argument then i am not able to access the request

This would be relatively standard based on what you are asking:

class CustomAuth:

      def verifyToken(self, token):
          self.token = token
        

      def login(self, request):
            self.request = request
            data = request.body

            
            # how do i call verifyToken?
            x = self.verifyToken(self.token)
            # if i use self as first argument then i am not able to access the request
            r = self.request

Also, note the comments suggesting the @staticmethod method as an alternative.

CodePudding user response：

The point of "self" is to link the functions and variables to the instance. If your function don't use class internal variables or other function you can decorate with @staticmethod and you will access it as usual.

For more details google it. https://www.w3schools.com/python/gloss_python_self.asp#:~:text=The self parameter is a,that belongs to the class.

I find it strange the way you use the class. Why don't you instantiate with parameter token, and don't need to use the function to assign token to internal class variable.
