cjai: Since your content would inherit from CMF/Plone base content classes, I think you have to provide your special “add” handle method, similar to the handle_send() in my second example (ContactForm), and you need to use the entry point that CMFPlone offers to create an object, “the CMFPlone way”::

from Products.CMFPlone.utils import _createObjectByType

_createObjectByType(‘MyContact’, self.context, id=id,
title= data['firstname'] + ‘ ‘ + data['lastname'], )

Note that this is in theory ; I have previously found a bug with _createObjectByType unable to create correctly Z3-based content type objects (which is the case of plone.app.content-based types), because of the way their factory work, and I used a patch to make it work (as an example, if you face the same problem, you can see here: http://tinyurl.com/47u8yf).

Hello, do you have any example how to create content with plone.app.content? I use item class from plone.app.content instead OFS. My code is like this :

from plone.app.content import item
class MyContact(item.Item):
…
…

That code is instead of :

import OFS
class MyContact(OFS.SimpleItem.SimpleItem):
…
…

But I got error in this url : http://paste.plone.org/23747

Do you have any clue how to solve it? Thank you.

This wasn’t supposed to be a smiley in that code but a closing parenthesis. Also, it’s ‘ContactAddForm’, not ‘form’ as the first argument:

# my.example/my/example/browser.py
from plone.app.z3cform import layout
ContactAddFormView = layout.wrap_form(
ContactAddForm, label=”Contact Add Form”)

Since plone.app.z3cform 0.3, you need to define your form wrapping view like this:

# my.example/my/example/browser.py
from plone.app.z3cform import layout
ContactAddFormView = layout.wrap_form(form, label=”Contact Add Form”)

This is instead of:

# my.example/my/example/browser.py
class ContactAddFormView(base.FormWrapper):
form = ContactAddForm
label= “Contact Add Form”

Note the change from plone.z3cform to plone.app.z3cform. The how-to on plone.org has been updated with these changes.
