ModelForm has no model class specified.
Matthew Pava
I have a form similar to that declared below:
class LineItemForm(Mixin, forms.ModelForm):
cost = forms.FloatField()
field_order = [‘part’, ‘cost’]
class Meta:
model = LineItem
fields = [‘part’]
And then I have another form that inherits from that:
class InventoryTransactionForm(LineItemForm):
class Meta:
fields = [‘part’, ‘document’]
exclude = []
I have two views that use the InventoryTransactionForm. View A uses it in a formset like so:
InventoryFormset = modelformset_factory(LineItem, InventoryTransactionForm, formset=InventoryTransactionFormSet)
inventory_formset = InventoryFormset(request.POST or None, initial=[{"part": default_part}])
View B uses just the form:
form = InventoryTransactionForm(
request.POST or None, instance=inventorytransaction.transaction.lineitem, prefix="inventory", create_mode=False
)
When I load View B, I get this exception:
ModelForm has no model class specified.
Everything works fine in View A.
Any ideas, thoughts, or suggestions?
Thank you,
Matthew
