I'm doing it this way :
def render(self):
if self.errors is None or self.errors:
return super(EditPerson, self).render()
self.request.response.redirect('..')

Thanks Jürgen! That works perfectly for me.
Looking one step forward, I would like to redirect the user back to
the previous page from whence they came (without using sessions). I
figure I am going to need to stash that value on my EditForm class
and
then pull it up during the redirect in my render method. I've
done my
best to explore this, but I can't figure out where the previous page
information will be available on my EditForm.
** Where should I stash previous page information for future
redirects
on my EditForm? **
That's also an unsolved use case I have.
The 'default' template of 'FormBase' contains the slot 'extra_info'
which could be filled with some hidden input fields.
I defined a new template for my own EditForm.
But now I would like to use the existing template in formlib
'pageform.pt' and fill the slot but don't know how.
Is this a possible way and the right way ?
How can I use the existing template ?
It must be useable with metal:use-macro somehow.
Yes, we write custom templates that use hidden input fields. We
reuse the existing template by putting the default template on
another attribute of the view class, and then saying 'metal:use-
macro="view/...'
For instance
class MyForm(zope.formlib.form.EditForm):
base_template = zope.formlib.form.EditForm.template
template = (...a named template if you want, or just a page
template directly...)
Then in your template, you can refer to macros in the original like
this:
'metal:use-macro="view/base_template/macros/extra_info"'
Notice that the pageform.pt *extends* the context/@@standard_macros/
view macro, so you can customize slots from your main template too.
There are lots of other solutions, but that's the one I know of that
I consider to be best ATM.
