Re: Check box form
Thanks for all the help, I am still using some oldforms because i
picked up this project
from someone else, so thanks for the html work around. I will keep the
newforms method in mind as well when an update rolls around. Again,
this was
a great help.

Re: Check box form
Hi Jacob,
I had a similar situation. The key points that I wanted were:
1. Still use a normal Django newform that can validate itself etc.
2. Control of HTML remains in the template.
The way I went about it was to:
1. Create a new form, say ManageRegistrationsForm that takes a result-
set of registrations in the constructor and creates a checkbox field
for each registration:
class ManageRegistrationsForm(forms.Form):
"""Manages registrations with checkbox for each"""
def __init__(self, registrations,*args,**kwargs):
super(ManageRegistrationsForm,self).__init__(*args,**kwargs)
# Now add a checkbox for each registration
self.registrations = registrations
for r in registrations:
self.fields[str(r.user.id)] = forms.BooleanField(
label=r.user.get_full_name(),
required=False
)
And then,
2. Define another member function of the form that returns a list of
tuples (input field, registration):
def get_inputs_with_regos(self):
""" Returns a list of tuples (input, registration) for the
form """
from django.newforms.forms import BoundField
return [
(
BoundField(self, self.fields[str(r.user.id)],
str(r.user.id)),
r
) for r in self.registrations
]
And finally, that allows you to do the following in the template:
{% for input, r in form.get_inputs_with_regos %}
{{ input }}
{{ r.user.get_full_name }}
{{ r.user.email }}
{{ r.user.get_profile.mobile_number }}
etc.
And you can then add your normal form clean methods etc. for your form
validation.
Hope that helps.

The template can generate its own HTML easily enough without using a
forms.Form, e.g.
{% for t in thingylist %}
{{ t.longname|escape }}
{% endfor %}
Then, when you're processing the POST form data, it's absolutely vital
that you call the POST.getlist('thingies') method rather than just
dereferencing POST['thingies'] !
if httpreq.POST.has_key('thingies'):
selectedthingies = httpreq.POST.getlist('thingies')
I struggled with that for quite a while when I made my first checkbox
form in Django; I was expecting a list or tuple to be right there in
the POST for me to grab directly. But nope, you gotta use the
getlist() method.
