Re: django formwizard NoFileStorageConfigured

Have either of you done a search of Trac to see if this issue has been reported previously? If there isn't, could you please open a ticket so that the problem isn't forgotten.

Yours,

I've just been hit by this too, exactly the same set up and problem. I'd love a fix/solution.

[CAUSE]

                        not hasattr(cls, 'file_storage')):
                    raise NoFileStorageConfigured

[RESOLUTION]

subclassing is not enough.  I inherited from both
NamedUrlSessionWizardView and FileSystemStorage, as shown below, but I
keep getting this error.

class FamilyWizardView(CommonWizardView, FileSystemStorage):
    pass

I noticed an instance variable in formwizard called storage_name but
it is used for child clasess Session and Cookie WizardViews. Si it's
no relevant

please, could you shed some light  ?
