Like Massimo wrote and advised against, it is possible like you are
suggesting to create forms on the view. A simple way to keep logic in the
controller is to do something like this (which is what I think you want):
In the controller you pass some you data - for example a set of rows
"contacts"
In the view:
{{for rec in contacts:}}
<div id="edit_contact_block{{=rec.id}}"
class="info_block_body edit_contact_block" style="display:none">
{{=edit_contact_form(rec)}}
</div>
{{pass}}
Please note:
* each div as a standard name with the contacts id added as sufix
"edit_contact_bock{{=rec.id}}"
* initial style="display:none" the form is shown by the user using jquery
The forms are created with a function defined in the controller. Here's the
function code:
def edit_contact_form(contact):
id='edit_contact_form'+str(contact.id)
form = SQLFORM(db.contact, contact,
fields=['contact', 'contact_role', 'value_offered',
'value_closed'],
submit_button='Save',
showid=False, _id=id,
deletable=True,
delete_label='Delete:')
form[0][-1][1].append(INPUT(_type="button", _value='Cancel',
_class='cancel_edit_contact',
_style="margin-left:3px;"))
if form.accepts(request.vars, session, formname=id):
redirect(URL(r=request, f='view_opportunity', args=contact.oppty.id
))
elif form.errors:
response.flash='Edition failed!'
return form
Please note the juju:
id='edit_contact_form'+str(contact.id)
...
if form.accepts(request.vars, session, formname=id):
Which links each form to a single contact.
Note that some javascript (jquery) is needed to show and hide data and
forms. Since the specific javascript / css to do this is limited to this
specific page (in my app), I append it to response files:
{{response.files.append(URL(r=request,c='static/biz',f='common.js'))}}
{{response.files.append(URL(r=request,c='static',f='view_oppty.css'))}}
{{response.files.append(URL(r=request,c='static/biz',f='view_opportunity.js'))}}
{{extend 'layout.html'}}
I assume that you either show every form or know how to do this in
javascript/jquery.
If anyone as a clearer method to do this I am VERY interested in knowing
about it!
HTH,
Miguel
