Working with Django 1.3
I can create and run an inline formset without problems using Approach 1.
However, when I try Approach 2, then I get the error below, triggered by
the line shown.
TypeError at /uploads/details/1
__init__() got an unexpected keyword argument 'instance'
Clearly, my syntax is wrong somewhere, but how do I go about fixing this?
Thanks
Derek
Approach No.1 - NO validation
# view file
UploadFieldFormSet = inlineformset_factory(Upload, UploadField,
max_num=None,
extra=9, can_delete=False)
if request.method == 'POST':
...
else:
formset = UploadFieldFormSet(instance=upload)
Approach No. 2 - Form validation
# form file
class UploadFieldFormSet(BaseFormSet):
def clean(self):
if any(self.errors):
return
# need to add special checks here...
# view file
UploadFieldFormSetFactory = inlineformset_factory(Upload, UploadField,
formset=UploadFieldFormSet,
max_num=None,
extra=9,
can_delete=False)
if request.method == 'POST':
...
else:
formset = UploadFieldFormSetFactory(instance=upload) # returns
error
