[ACTION]
Subclass NamedUrlSessionWizardView and instantiate it with a set of
forms one of them containing a FileField
class CommonWizardView(NamedUrlSessionWizardView):
pass
class FamilyWizardView(CommonWizardView):
pass
[RESULT]
File "/accounts/urls.py", line 66, in <module>
family_wizard = FamilyWizardView.as_view(named_family_forms,
url_name='family_step', done_step_name='family_wizard')
File "python2.7/site-packages/django_formwizard-1.0-py2.7.egg/
formwizard/views.py", line 109, in as_view
initkwargs = cls.get_initkwargs(*args, **kwargs)
File "python2.7/site-packages/django_formwizard-1.0-py2.7.egg/
formwizard/views.py", line 583, in get_initkwargs

**kwargs)
File "python2.7/site-packages/django_formwizard-1.0-py2.7.egg/
formwizard/views.py", line 166, in get_initkwargs
raise NoFileStorageConfigured
TemplateSyntaxError: Caught NoFileStorageConfigured while rendering
[CAUSE]
class WizardView(TemplateView):
@classmethod
def get_initkwargs(cls, form_list, initial_dict=None,
instance_dict=None, condition_dict=None, *args, **kwargs):
"""
Creates a dict with all needed parameters for the form wizard
instances.
"""
....
# check if any form contains a FileField, if yes, we need
a
# file_storage added to the wizardview (by subclassing).
for field in form.base_fields.itervalues():
if (isinstance(field, forms.FileField) and
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 ?
