Hello all,
I'm trying to build this following link feature in django,
http://demo.smarttutorials.net/jquery-autocomplete/
Here by choosing serial_no and the rest of the fields name and author
should be auto populate. Auto populate works for first inline formset and
able to save it but when I add another inline formset auto populate is not
working plus I'm unable to delete it or save it.
models.py
from django.db import models
class Book(models.Model):
serial_no = models.IntegerField(max_length = 100, unique = True)
name = models.CharField(max_length = 50)
author = models.CharField(max_length = 50)
def __unicode__(self):
return self.name
class CustomerOrder(models.Model):
name = models.CharField(max_length=256)
def __unicode__(self):
return self.name
class Order(models.Model):
customer = models.ForeignKey(CustomerOrder)
serial_no = models.IntegerField(max_length = 100, unique = True)
name = models.CharField(max_length = 50)
author = models.CharField(max_length = 50)
quantity = models.IntegerField(max_length = 100)
def __unicode__(self):
return self.name
