Re: Setting default form value in template

Hey, figured it out for the most part. Had to use a little jquery to
get it to work.
This is what it looked like:
<script type = "text/javascript" src="/media/js/jquery.form-
<script type="text/javascript">
function displayProfiles(profiles) {
member = profiles.values[0];
var fname = member.firstName;
var lname = member.lastName;
var id = member.id;
{{ form.as_table }}

And in the forms.py file, I just set a widget for each of the forms,
and then as one of the attrs, I stated the id's (as shown in the
last_name = forms.CharField(widget = forms.TextInput(attrs =
{'id':'lname'}), required=True)
Hope you like it. :)
