Have a look in django/forms/forms.py at the class BoundField. That is the object that is a "field" in the template. You can see there how the data value is retrieved by the code.

I'm doing an app with django/dojo, and I need to display fields manually, I could make them programatically, but that would be "a lot more work", the problem I have now is that when the user submits data with errors, I cannot redisplay the fields with values, so there is no way to degrade gracefully (I'm not that interested on that actually, but could be nice).

In the current code, that particular value isn't easily available, no,
and that is probably an omission we should fix.
That particular value comes from one of three sources. In order of
highest priority to lowest, they are:
(1) Data submitted to the form (for redisplaying submitted data
for errors).
(2) Initial data provided to the form class
(3) Initial data provided to the field class (when it was
created as part of the form).
The code does a semi-complex dance to pull out the right value and it's
not something you can really emulate at the template level. That's
something worth adding for Django 1.1.

Malcolm

accessing to a field value in the template
Hi,
I am new in Django and I am wondering if it is possible to access to a
form field value in through a template.
I know that I can access to the field by {{field}} and also can access
to the field.label, errors, label_tag, but I would like to access to
the intial value of a field.
Suppose I have the field =
it is possible to get the value only through a template ? Something
like field.value ? or field.data ? or field.initial ??
I have tried all of them but cannot access to the value. If you have
any hint it will be appreciate.
