[Zope3-Users] Hook into edit-form post

As Marco said, use formlib, e. g. like this

    menu="zmi_views" title="Edit a SidPage"

    class="myview.EditView" <--- ***


and in myview.py

  from ... import ISidPage
  from zope.formlib import form
  class EditView(form.EditForm):


    # here you can redefine some of the
    # methods/actions/etc. of form.Editform

(personally I prefer <browswer:page> over
<browser:editform>) and I am redefining
e. g.

   template = namedtemplate.NamedTemplate('...')

   def setUpWidgets(self, ...)

   @action("...", ...)

Note that there is one action already defined in EditForm
called handle_edit_action. You can reuse this one
(and add some more actions) with

  actions=form.EditForm.actions[:]  (*, see below)

or if you leave out line (*) you effectivly start
with no actions - i. e. you just use your self-defined

Also I found the setup of a template (a ZPT) in EditView
a bit tricky, what works for me is this:

in myview.py

  my_pt = namedtemplate.NamedTemplateImplementation(

as well as (mentioned above already) in myview.EditView:
  template = namedtemplate.NamedTemplate('whatever')  

configuration with

  <adapter factory=".myview.my_pt" name="whatever" />

Have a look at these files:
