Hi!
I need an order form that will handle the orders for X number of
students and Y number of products. I have a working solution that
creates a <form>..</form> for every product and submits it on
onchange, but I was wondering if there was more of a "django" way to
do this.
I would like my form to look like this:
--------------
Student name | Product 1: <quantity> | Product 2: <quantity> | sum:
price*quantity etc
Student name | Product 1: <quantity> | Product 2: <quantity> | sum:
price*quantity etc
Student name | Product 1: <quantity> | Product 2: <quantity> | sum:
price*quantity etc
Student name | Product 1: <quantity> | Product 2: <quantity> | sum:
price*quantity etc
Student name | Product 1: <quantity> | Product 2: <quantity> | sum:
price*quantity etc
| total q of this product | total q of this
product | sum:
total price
--------------
The school administrator need to add/remove products and hey should
be able to tab through the form(not hitting any save button for every
field.)
My models:
class Student(models.Model):
first_name = models.CharField(maxlength=30)
last_name = models.CharField(maxlength=30)
class Product(models.Model):
name = models.CharField(maxlength=20)
description = models.TextField()
price = models.DecimalField(max_digits=5, decimal_places=2)
class Order(models.Model):
student = models.ForeignKey(Student)
product = models.ForeignKey(Product)
quantity = models.IntegerField()
My template code:
{% for student in students %}
{{ student.first_name }} {{ student.last_name }}
{% for product in products %}
{{ product.name }}
<form> <input type="hidden" product.id and student.id />
<input type="text" value="{% order-quantity student.id
product.id
%}" onchange="run ajax query to place the order"/>
</form>
{% endfor %}
{% endfor %}
order-quantity is a custom template tag with this logic: orders =
student.order_set.filter(product=product) and then returns the
quantity from the first order object.
Any help would be greatly appreciated!
