[Zope3-Users] keeping GET data in a formlib based form
Hi everybody, I have a formlib based form. It is not accesible from an application menu because it is part of a wizard like process. The first time it gets called the url looks something like this: http://localhost:8080/myapp/mycontent/myform?myarg=23 So in the update() method of the form I read the myarg argument from the request and use it to setup some widgets in a particular way. The problem is that when the action buttons of the form are clicked, and the form is reloaded, the 'myarg' argument is lost and I run into problems. I need a way to keep 'myarg' information in my form for subsequent calls. Ideally I would like some mechanism that ends writing an input type=hidden id=myarg value=23/ tag in the html because that way my code: def update(self): [..] data = self.request['myarg'] [..] will still work, right? I have thought about extending the formlib template to just do that or maybe adding a form.Field to my form with a special Widget associated to it. No idea of what's the best aproach. Anyone has pointer for this? thanks Lorenzo Gil ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re[2]: [Zope3-Users] correct display of Text field in a view
Hello Ivan, I don't think that you'll need IMultiLineText and MultiLineText. That's why IText and Text are there for. You'll have to register the widget for IText or use it directly in your view with CustomWidgetFactory. In fact it's a good question why Z3 doesn't provide such a widget for Text. The current widget is just Displaywidget which eats the newlines.

I have thought about extending the formlib template to just do that or maybe adding a form.Field to my form with a special Widget associated to it. No idea of what's the best aproach. Anyone has pointer for this? Maybe the simplest solution is to use session for storing this data, eg.: in update you check if there is 'myarg' in request, and if so then put this into session. If there is no 'myarg' in request you get this from session. If you want this passed via POST/GET then you may try with hidden() method of widgets, or write own widget that renders as a hidden input, like: class EntryWidget(SimpleInputWidget): def _toFieldValue(self, input): return unicode(input) def __call__(self): return self.hidden() and assign this widget to field that will represent 'myarg': self.form_fields['myarg'].custom_widget=EntryWidget You will possibly have to change the line: data = self.request['myarg'] because your input will have form prefix. I'm not sure, but you may have some issues with this solution when doing resetForm etc. -- Maciej Wisniowski ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Formlib and action conditions
Currently, when you have a condition on an action, and it is satisfied on render time, you'll get a button. However, if you click that button and the condition happens to be false in the subsequent request, the action will not be executed, with no error message or notice. Is this intended?

We need to add search and filter functions to our current app, where the user might be able to create quite _sophisticated_ filter criterias.

Some questions arose: - Is it necessary/worth adding indexes on all attributes? it depends on what you need to search. You may want to index everything as a whole in each object, in which case you just need one index, based on an adapter's getsearchabletext method that returns some kind of concatenation of all attributes; or you may want to be able to search in one particular attribute, so you have to create an index for this particular attribute. The most important is deciding how is built the indices. But I think there is no problem changing the indexation method, since reindexing is just a matter of clicking on a button, and waiting a some time. - How does the index perform on modification and retrieval? not sure to understand the question.

the templates renders without errors, but if i use i18nextract to get the

i just tried a bit more, so i guess the problem is, that self.__name__ is in my
case dynamically filled.
is the only way there to add these entries by hand to the .mo file, or are there
other approaches to this?

Re: [Zope3-Users] formlib with no zodb
you don't need anything special.. if you have orm mapped objects just write formlib forms for them, with a custom traversal to retrieve. if your doing sql by hand, then just write adapters for the form context that update the relevant rdb data. as an example, alchemist constructs formlib forms that work against objects mapped from a relational database with no zodb footprint. its all z3 tech, but its targeting deployment for plone/z2. http://svn.objectrealms.net/view/public/browser/Products.alchemist/trunk/browser/ hth, kapil On Wed, 14 Mar 2007 10:23:53 -0400, tyson [EMAIL PROTECTED] wrote: Is it possible to build a page with formlib, widgets, and a page template without using the ZODB or ZMI.
