Re : Re : [Zope3-Users] formlib problem
Hi, when I use formlib the traditional way (registering the page via ZCML, going to it via the ZMI), everything works fine. The problem is I can't access it programatically. The thing I try to do is : - call a method via JSON RPC (by the way jsonserver is great ;-)) - in this method I get my object (through sqlos, which is nice too ;-)) and then call the formlib class to render my page in html - send back the html which is used to update my page. Has anyone tried to use formlib this way, I really need to use AJAX and it seems that I can't have both working together, I must be missing something.

Hi Jim,
the Items object is my object, linked to my items, table which implements the IItems interface I use for my form:
from neteven.interfaces.items import IItems
from zope.formlib import form
class ItemsForm(form.EditForm):
form_fields = form.Fields(IItems)
form_fields = form_fields.omit('dateLastUpdate')
Items is defined this way:
from zope.interface import implements
from sqlobject import *
from sqlos import SQLOS
from neteven.interfaces.items import IItems
class Items(SQLOS):
implements(IItems)
class sqlmeta:
table = 'items'
When I add this zcml declaration :
browser:page
for=.interfaces.items.IItems
name=edit.html
class=.forms.items.ItemsForm
menu=zmi_views
title=Edit a Item
permission=zope.ManageContent
/
everything works fine from the ZMI (I created simple containers to test that).
My JSON server side code is:
def getItemEdit(self, itemId):
item = Items.get(itemId) #a sqlos function to get an Item instance
from the table given its Id
return ItemsForm(item, self.request)()
The fact is I don't use any page template right now ( though I might do this later to have a nice GUI).
Actually, you are using a page template.
Calling ItemsForm() invokes the render() method of
zope.formlib.form.FormBase, which uses pageform.pt in the zope.formlib
folder by default. This is where title_or_id is requested.
You may wish to set a different template for your ItemsForm class.
Have you tried subclassing form.SubPageEditForm instead of form.EditForm?

Re: FW: Re : Re : [Zope3-Users] formlib problem
Stéphane, i'm working on what sounds to be a pretty much identical issue currently... i'm attempting to use formlib and jsonserver. i've been throwing around a number of possible solutions, but none that i'm comfortable with so far. i agree, i don't know how to access my form.Form class programmatically, but i don't want to sacrifice all the utility provided me by formlib (errors, checking of invariants, etc, etc). i've considered having my exposed json-rpc methods pull in the params explicitly, and then wrap them back up into formlib-style data (if it's possible, i haven't had a chance to try yet), and then use the handleSubmit and applyChanges logic out of formlib directly. but i'm not happy with that solution. i would like to find a way to build my forms agnostic of how they're to be used, and associate jsonrpc:view's to a particular content area that can access the forms i've displayed. i've been really happy with the ability to build formlib forms into viewlets, and use them where/how i want... but if that keeps them from being ajax-y accessible, it will present a significant hurdle :\ if anyone has any suggestions, or has solved this kind of problem before, i'd really appreciate pointers. if i stumble across anything that seems useful, i'll post it back out.
