Django View Class : Name 'self' Is Not Defined

I'm working on the Django framework. Now I'm making a Class for user registration like below. I got a error on the line number 6. Could you give some help? 1: class JoinForm(forms.

Solution 1:

This is unrelated to Django; the body of your class definition has its own namespace, and runs in the order written, so at this point:

classJoinForm(forms.Form):
    ...
    YEAR = self.makeYearChoice(self,1940)  # here
    ...

not only is self not defined, makeYearChoice isn't either! You could fix this one of two ways, either:

1. Move the method definition above the setting of the class attribute, and call it directly

   classJoinForm(forms.Form):
       ...
       defmakeYearChoice(self, startYear):  # define the method first
           ...
   
       YEAR = makeYearChoice(None,1940)  # don't have an instance, but who cares?
       ...
   

   which leaves you with a redundant instance method once the class is defined; or

2. Make it a standalone function and just call it within the class:

   defmakeYearChoice(startYear):
       ...
   
   classJoinForm(forms.Form):
       ...
       YEAR = makeYearChoice(1940)  # no fuss about self argument
       ...
   

I would strongly favour the latter. Also, you should read the style guide; method and attribute names are generally lowercase_with_underscores, and you should have spaces after commas.
