In forms.ModelForm Meta.fields needs to be a list if only single field is defined

[casseen]

The following is not working! It returns a broken form if instantiated:

class ExampleForm(forms.ModelForm):
    class Meta:
        model = ExampleModel
        fields = ('single_field')

It is working if Meta.fields is set to a list:

class ExampleForm(forms.ModelForm):
    class Meta:
        model = ExampleModel
        fields = ['single_field']

If this is intended behaviour it should be documented! But I guess I should work in both ways. This behaviour is introduced with r10062.

Last line of description should say:

[...] But I guess *it* should work in both ways. [...]

It looks to me like your sequence version is broken by virtue of the fact that you have left off the trailing comma for your single-element tuple. If that is not the cause of the problem, you may reopen but please include some details of what 'broken form' means.

Ok, a final comma clears this case! I am sorry. Still learning python as you see ; ) I was confused because it worked without a final comma before r10062.
