[Zope3-Users] Generate edit form from user setting
Hello,
I have a zope.app.preference.preference.PreferenceGroup based on an
IUserSettings interface for which I want to generate an edit form.
I've tried to do it with a class based on EditForm but that does not worked
for me since the EditFrom changes the self.context object. If I simply
replace self.context by the object I got from UserPreferences it complains
about PreferenceGroup being not adaptable to IUserSettings (and it's right
about that).
class UserSettings(form.Form):
form_fields = form.Fields(IUserSettings, render_context = False)
@form.action("Change")
def handle_change_action(self, action, formData):
pass
Of course I need to initialize the from with the values from the the
PreferenceGroup object. Is there a better way than modifying the request like
request.form['form.max_size'] for each field? I couldn't find one in the
documentation but I'm almost sure there is a more elegant solution (since
it's Zope!).
Thanks,
Florian
