Hi All,
I've been battling with formlib for the last three days now and, while
I've learnt a lot, it's nearly driven me crazy. I'm trying to use it to
create simple search form, i.e., a form that does input validation,
remembers the values you entered, etc., but is not tied to a persisted
object.
I've got the form rendering and processing requests, but I'm completely
stuck on getting the form to remember the values I just entered after a
form post.
Has anyone got any suggestions ? Here's what I've got so far, the latest
attempt being to use a dummy object to provide the context, which also
doesn't seem to work:
#--------------------------------------------------------------------------------------
# Classes for bulding the search form
#--------------------------------------------------------------------------------------
class UserSearchForm (Form):
# Vocab for boolean items
bool_vocab = SimpleVocabulary.fromItems([('Any', ''), ('Yes',
'true'), ('No', 'false')])
# Form fields
form_fields = Fields(Choice( __name__='is_verified',
vocabulary=bool_vocab,
title=u"Is verified?",
description=u"Has the users email address
been verified ?"),
Choice( __name__='is_opted_in',
vocabulary=bool_vocab,
title=u"Has opted in for emails",
description=u"Has the user opted in for
emails ?"),
Choice( __name__='is_old_extension_user',
vocabulary=bool_vocab,
title=u"Is not using the latest extension",
description=u"Is the user using the
latest extension ?"),
Choice( __name__='is_extension_user',
vocabulary=bool_vocab,
title=u"Is an extension user",
description=u"Is the user using the
extension ?"),
)
# Vocab for email templates
templates = EmailTemplates()
template_vocab = SimpleVocabulary.fromItems(templates.get_tuples())
form_fields += Fields(Choice( __name__='template',
vocabulary=template_vocab,
title=u"Email template?",
readonly=True,
description=u"Choose an email template ?" ),
)
prefix = 'search'
label = 'Search for Users'
template = ViewPageTemplateFile('templates/searchform.pt')
actions = form.Actions(
form.Action('search', success='process_search'),
form.Action('process',
success='process_action'),
)
_results = None
#--------------------------------------------------------------------------------------
# Dummy search form context object
#--------------------------------------------------------------------------------------
class UserSearchFormData:
def __init__ (self):
self.is_old_extension_user = True
self.is_extension_user = False
self.is_verified = True
self.is_opted_in = False
#--------------------------------------------------------------------------------------
# Classes for registering the search form as a content provider
#--------------------------------------------------------------------------------------
class UserSearchFormProvider:
implements(IContentProvider)
adapts(Interface, IDefaultBrowserLayer, Interface)
def __init__(self, context, request, view):
self.context = context
self.request = request
self.__parent__ = view
self.obj = UserSearchFormData()
self.form = UserSearchForm(self.obj, self.request)
def update(self):
pass
def render(self):
import pdb; pdb.set_trace()
return self.form()
#--------------------------------------------------------------------------------------
# User admin view
#--------------------------------------------------------------------------------------
class UserAdminView (BrowserView):
def __init__ (self, context, request):
self.context = context
self.request = request
# Set up the form content provider
provideAdapter(UserSearchFormProvider,
name="vortexuser.UserSearchFormProvider")
Many thanks for any help.
Cheers, Andrew.
