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:
Yes, I do the same and use a self-made class, called ActionForm for that,
it's quite simple:
class ActionForm(Formframe, form.Form):
Generic form for context-less patterns
def updateWidgets(self):
self.widgets = getMultiAdapter(
(self, self.request, self.getContent()), IWidgets)
self.widgets.ignoreContext = True
self.widgets.update()
Then I have a persisten object, that acts as an entry point to my view, and
which may provide various methods, e.g.:
class SearchData(persistent.Persistent):
implements(ISearchData)
def search_data(self, **kd):
# Here the data is retrieved, in my case from a relational database
return data
And then there's the view:
class ViewSerachKunde(ActionForm):
formErrorsMessage = _('There were some errors.')
template = ViewPageTemplateFile('pt/searchdata.pt')
fields = field.Fields(IViewSearchData)
# If data is found, it's stored in a view-object-attribute
found_data = None
@button.buttonAndHandler('Search', name='search')
data, errors = self.extractData()
if errors:
self.status = self.formErrorsMessage
return
self.found_data = self.context.search_data(**data)
And then in my template file I have something like this (please note that I
use a custom library for displaying fields (formsnippet):
--! This displayes the search-widgets --
span tal:repeat=widget view/widgets/values
span tal:replace=structure widget/snippets/div /
/span
--! And this displays the found data --
div tal:condition=view/found_data
h2Found Data:/h2
span tal:replace=structure view/found_data/
/div
Best Regards,
Hermann

That's what I meant by postmortem debugger publisher. I was being fuzzy: your terminology is correct. However, my observation stands. I know Jim likes it, among others, but I have found it to not work the way I want enough to be a nuisance. I seem to recall that this may be related to the ZODB connection being closed, but I could be remembering incorrectly.
