Re: [Zope3-Users] formlib vs. cancel button
I dont know if it is the proper way, but when I return an empty string there is no validation error. This was also one of the strangest things I found out with formlib. Dennis Martin Aspeli escribió: Hi, I really thought I knew how to do this, but now I can't get it to work and I'm really confused. I have a formlib EditForm, with an action like this: @form.action(Cancel, validator=lambda *args, **kwargs: True) def handle_cancel_action(self, action, data): nextURL = self.nextURL() if nextURL: self.request.response.redirect(self.nextURL()) return '' However, I still get validation errors when I click Cancel. I also tried a validator to return None, and no validator at all, and validator=None, they all have the same effect. Is there a proper/easy way of doing this?

[Zope3-Users] redirect to views dynamically
Hello List, one question about views: I know that is is possible to register a default view for an object. Is there a way to decide, at runtime, which view to call? Maybe a traversal adapter can do this,but is there an easier way? Dennis ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] default text for dropdown widget empty selection
You can override the setupWidgets() method of your formlib class and write something like this. (assuming that project is your dropdown field and your view is called MyAddingView) def setUpWidgets(self, ignore_request=False): super(MyAddingView, self).setUpWidgets(ignore_request=ignore_request) self.widgets['project']._messageNoValue = (no project) The thing that bothers me is that once you assign a value it is not possible to set it back to no value. Anyone knows how to fix this? Dennis Roy Mathew escribió: Hi Folks, Currently, the builtin dropdown widgets show the string '(no value)' as the empty default. Is it possible to show different text in its place? ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] 3 step selection widget
hello, I have the current use case to write a 3 step-selection widget. The user has to choose 1. Division, 2. Cost Center and 3. Budget (which is the actual choice) So I need 3 different vocabularies that change according to the current context. It would be nice to have a onChange event. Anyone has done something similar before? Thanks, Dennis ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Zope 3 UML Model / Architecture

[Zope3-Users] better selection widget
also if this is just to select a supplier from the table, i'd recommend having a look at the vocabulary framework... i put together a really simple one for the states vocabulary in orgpeople, but you can do more complex examples, see zope.schema/sources.txt it allows you to bind a vocabulary to context before fetching values. thanks i will have a closer look to it. I also have phillip's new book now and there is a section about voabularies and sources. so in your opinion, what would be the most sane way to have a supplier selection (being part of a purchase requisition edit form) on a different screen? (I would like to have a more sophisticated supplier selection where you have a table view with search filter and possibility to create a new one) I thought of many possibilities, probably half of it is nonsense: - right now I have it like this (not very good solved at all): I use an objectwidget in the purchase requisition edit, that only serves as display and contains a button to the supplier container that is acquisitioned from the mapped instance. here I link every entry in the table with a link like purchaserequisitions/3/suppliers/4/@@selectthissupplier. Here I would like to assign prinstance.supplier = thissupplier, but of course thissupplier not provides IObject (Objectwidget) which leads to an error. direct db update here is nonsense because I want the update only when the complete transaction of the predit form is savedso its a one way. - I can see clearly that this is nonsence, because I am not correctly using the schema, the supplier relation has to be a IChoice and not an IObject. Maybe it is also nonsence to have the business logic in the __call__ method of @@selectthissupplier view, I would like to have an action here but I think if you render the table with zc.table it is not possible to have an action for every single row, is it? - so it would be possible to take the ItemsWidgetBase (already contains a vocabulary) and build a custom view upon that shows the details of the currently selected supplier and offers a button supplier select to the table view. However, I think it is difficult to have the table view updating the parent edit form. Actually when the table view is an independent view it is not a parent form at all, I have to do the updates manually, in addition to that the previously entered request data will probably be lost when I dont pass it manually. - probably the best option is, I recently thought, is to pack the table selection view into a somehow modified sequence selection widget, that has a source / vocabulary having all action happening same form but only show this widget and hide everything else. so we would achieve to have all previously entered data on the edit form still in the request easily and have a true parent form - child form relation.

[Zope3-Users] which widget to subclass for custom widget?
Sorry I have to bother you once more regarding formlib co :-) (really sorry) In my application I need something very user defined In the Edit Form Edit Purchase Requisition I would like to have a section Supplier Selection, that should operate as a widget. Basically I will use a schema Choice Field as a base, I will just create another view for the choice than the default select field. The whole thing should be seen as generic that returns a value at the end that should be validated and saved: the supplier id (which is the idea of widgets in general what I understood until now) Here the details, should include the following: - question new supplier? radiobuttons yes / no (onchange event to disable / enable textfields that are part of the same widget) - 2 textfields name+address that allow to enter the new supplier info (disabled when above selection no) - link to an independent supplier selection page (with search and list view) - the selection made in the supplier selection page should be updated in the widget as well (overwrite setupWidgets method I think) when applying the form, check in the custom _validate method of my widget, if radiobutton yes / no. when yes then add new supplier else just check if value is already in table. So far the theory, now the first question is, which widget to subclass? SelectWidget, ItemWidgetBase contain vocabulary and probably too high level. SimpleInputWidget seems the better choice?

[Zope3-Users] Widget Error on direct __call__ with pt
Hello,
I am using the following code for a sequence widget.
class TableRecordSequenceWidget(ListSequenceWidget):
def __init__(self, context, field, request, template_='',
subwidget=None):
super(TableRecordSequenceWidget, self).__init__(
context, field, request, subwidget)
def __call__(self):
render sth
It works good as long as I write the rendered html directly in the
__call__ method.
But after a while it gets dirty, I would like to have it in a page
template..
However when I try to change it to return a page template in the call
method,
(like I found it in many examples)
def __call__(self):
class TemplateObjectWidgetView(ObjectWidgetView):
template = ZopeTwoPageTemplateFile(itemwidget.pt)
template = TemplateObjectWidgetView(self, self.request)
return template()
I have the following error:
Any help? Again, the version without the page template works perfectly
