Getting __init__() got an unexpected keyword argument 'instance' with CreateView of Django

Question

Some details:

Request Method: GET
Request URL: http://localhost:8080/user/create
Django Version: 1.5.1
Exception Type: TypeError
Exception Value: ____init__         


        

Answer 1

I override __init__() method incorrectly, without initial arguments, as show below

class MyForm(forms.ModelForm):
    ...
    def __init__(self):
        super(CaseForm, self).__init__()
        ...

And get this error as result

TypeError at /case/create

__init__() got an unexpected keyword argument 'initial'

To fix it, I set arguments to __init__() and pass them when call super class __init__(), see result below

class MyForm(forms.ModelForm):
    ...
    def __init__(self, *args, **kwargs):
        super(CaseForm, self).__init__(*args, **kwargs)
        ...
