Hi all,
I keep getting the above error and I am not sure what I need to do to
correct it. An example will assist.
my model:
class Product_Group(models.Model):
customer_id = models.ForeignKey(Customer, on_delete=models.CASCADE)
prod_group = models.CharField(max_length=30, unique = True,
verbose_name = "product group")
def __str__(self):
return self.prod_group
class Part_Number(models.Model):
customer_id = models.ForeignKey(Customer, on_delete=models.CASCADE,
related_name = 'customer')
prod_group = models.ForeignKey(Product_Group,
on_delete=models.DO_NOTHING, related_name='product')
part_number = models.CharField(max_length=40, unique = True)
part_description = models.CharField(max_length=60)
def __str__(self):
return self.part_description
My form:
from django import forms
from django.contrib.auth.models import User
from .models import Department, Product_Group, Part_Number, Reject_Reason,
Return_Reason, Supplier, Consumer
from accounts.models import Customer_User
class Report_GenerateForm(forms.Form):
part_number = forms.ModelChoiceField(queryset=None, label='Part Number')
reject_data = forms.ModelChoiceField(queryset=None)
select_data = forms.ModelChoiceField(queryset=None)
def __init__(self, *args, **kwargs):
customer_id = kwargs.pop('customer_id')
table_select = kwargs.pop('table_select')
product = kwargs.pop('product')
super(Report_GenerateForm, self).__init__(*args, **kwargs)
self.fields['part_number'].queryset =
Part_Number.objects.filter(customer_id= customer_id, prod_group =
product).select_related('prod_group')
if table_select == 1:
self.fields['select_data'].queryset =
Department.objects.filter(customer_id=customer_id)
self.fields['select_data'].label = 'Department'
self.fields['reject_data'].queryset =
Reject_Reason.objects.all()
self.fields['reject_data'].label = 'Reject Reason'
if table_select == 2:
self.fields['select_data'].queryset =
Supplier.objects.filter(customer_id=customer_id)
self.fields['select_data'].label = 'Supplier'
self.fields['reject_data'].queryset =
Return_Reason.objects.all()
self.fields['reject_data'].label = 'Reason for Return'
if table_select == 3:
self.fields['select_data'].queryset =
Consumer.objects.filter(customer_id=customer_id)
self.fields['select_data'].label = 'Customer'
self.fields['reject_data'].queryset =
Return_Reason.objects.all()
self.fields['reject_data'].label = 'Reason for Return'
