How to generate lots of redundant ajax elements like checkboxes and pulldowns in Django?
- by iJames
Hello folks. I've been getting lots of answers from stackoverflow now that I'm in Django just be searching. Now I hope my question will also create some value for everybody.
In choosing Django, I was hoping there was some similar mechanism to the way you can do partials in ROR. This was going to help me in two ways. One was in generating repeating indexed forms or form elements, and also in rendering only a piece of the page on the round trip.
I've done a little bit of that by using taconite with a simple URL click but now I'm trying to get more advanced. This will focus on the form issue which boils down to how to iterate over a secondary object.
If I have a list of photo instances, each of which has a couple of parameters, let's say a size and a quantity. I want to generate form elements for each photo instance separately. But then I have two lists I want to iterate on at the same time.
Context:
photos : Photo.objects.all()
and
forms = {}
for photo in photos:
forms[photo.id] = PhotoForm()
In other words we've got a list of photo objects and a dict of forms based on the photo.id.
Here's an abstraction of the template:
{% for photo in photos %}
{% include "photoview.html" %}
{% comment %}
So here I want to use the photo.id as an index to get the correct form. So that each photo has its own form. I would want to have a different action and each form field would be unique. Is that possible? How can I iterate on that? Thanks!
{% endcomment %}
Quantity: {{ oi.quantity }} {{ form.quantity }}
Dimensions: {{ oi.size }} {{ form.size }}
{% endfor %}
What can I do about this simple case. And how can I make it where every control is automatically updating the server instead of using a form at all?
Thanks!
James
