表格.py

class CustomerModelForm(forms.ModelForm):
    class Meta:
        model = Customer
        fields = (\'name\',\'address\',\'contact\',\'email\',\'state\',\'gstin\',\'pan\')
        
class SupplierModelForm(forms.ModelForm):
    class Meta:
        model = Supplier
        fields = (\'name\',\'address\',\'city\',\'manager\',\'contact\')
        widgets = {
            \'name\':forms.TextInput(attrs={\'class\': \'form-control\'}),
            \'address\':forms.TextInput(attrs={\'class\': \'form-control\'}),
            \'city\':forms.TextInput(attrs={\'class\': \'form-control\'}),
            \'manager\':forms.TextInput(attrs={\'class\': \'form-control\'}),
            \'contact\':forms.TextInput(attrs={\'class\': \'form-control\'}),
            
            }

class BrandMasterModelForm(forms.ModelForm):
    class Meta:
        model = BrandMaster
        fields=(\'brand_name\', \'suppliername\')
        widgets={\'brand_name\':forms.TextInput(attrs={\'class\': \'form-control\'}),\'suppliername\':forms.Select(attrs={\'id\':\'choicewa\',\'class\': \'form-control\',\'required\': \'true\'}),

        }

我正在尝试使用 formtool 用我自己的模板保存多步表单。但我收到错误

ManagementForm data is missing or has been tampered Django FormTools Wizard

保存第一个表单时，无法继续进行。
