[Zope3-Users] z3c.form: terms/validation and problems with context
I use a session-based wizard with plone.z3cform that uses the concept from z3c.formdemo's wizard. The content is kept inside a session until it is written into the db in .finish(). I have problems with Lists and Choices where the vocabulary needs a suitable context that the content from the session doesn't provide. By default my Vocabularyfactory fails to get it's data and returns a empty SimpleVocabulary. The widget is empty. I can fill the widget with my terms like that: def getTerms(self, factory): terms = term.Terms() terms.terms = factory(self.parentForm.context) return terms def updateWidgets(self): super(FachgebieteSchritt, self).updateWidgets() self.widgets['key_activities'].terms = \ self.getTerms(cv.KeyActivitiesVocabularyFactory) self.widgets['key_activities'].update() But saving the selected values fails. validator.SimpleFieldValidator calls the field's _validate()-Method with the wrong context (the content) and WrongContainedType is raised. My actual solution is to register a NullValidator for wizard.IStep and zope.schema.interfaces.I[List|Choice]. Is there a more elegant way, e.g. where updateTerms and SimpleFieldValidator.validate() can use the right context? A second, small problem is that I tried to use the Discriminator like the Doctest describes validator.WidgetValidatorDiscriminators(NullListValidator, view=interfaces.IStep, field=ITCommonAddressData['key_activities']) and thought the getSpecification-magic registers for the right Interface, but maybe I missunderstood the test. Registering an adapter by hand for zope.schema.interfaces.IList works. ..Carsten ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] Automatic schema field sanitation?
Hi Dennis, Dennis Noordsij schrieb: I would like to define a custom type inheriting from zope.schema.TextLine, which in addition to having a built-in constraint method also sanitizes the input. For example suppose you need to store codes of the kind: 3 letters, space, 3 numbers. The constraint uses a regexp, and this works fine. However it would be nice if I could also automatically capitalize the letters, such that abc 123 is stored as ABC 123 which is the presentation that should be used everywhere. Being able to do this automatically, just like the validation, would completely remove the need to remember to sanitize on input/output throughout the rest of the system. What would be the best way to implement this, ideally without needing to modify any of the standard zope.interface/zope.schema code? IIRC invariants can change the passed data even though they are used nearly exclusive for cross field validation. ..Carsten ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
