[Zope3-Users] Re: How to make content object return a view?
David Johnson wrote: I have a content object, that I want to return a view. How is this done? It usually isn't. This situation seems to come up frequently for me. What do you do? Content objects are usually dull. The only thing they do is store data. If you're using ZODB persistency, then a content object can be two lines of code: class MyContent(persistent.Persistent): pass In particular, content objects often have no methods and they definitely don't deal with the request. This is left to views. So, somethign in your app needs to deal with a request, write a view. In this case, the content object is a fax. The fax will include browser views as part of it's body. That seems like a backward approach. The fax body will probably be rendered using other views. The body rendering view should pull in other views. Not the fax object itself. I tried zapi.getView(), but this has been deprecated, and I don't quite understand the best approach. Don't mix storage and presentation :).

[Zope3-Users] getUtility outside of the zope.app
Hi. For the use of interfaces outside of zope.app, does getUtility have any value? Many thanks. Regards, David ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] Re: How to make content object return a view?
Thanks! You are right. After a re-read of your book last night, I think my problem is that I have not understood or dealt with adapters as of yet. It seems that is the proper solution to expressing content in the way I intended and seems to solve all my problems in this area. -- David ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Re: [Zope3-Users] Reference to a COM object (or other external resource) in a Zope object

I have to store a reference to this object somewhere in my Zope object. But, for obvious reasons, this COM object cannot be serialized so I cannot put it in any attribute of my Zope object. On the other side, initialisation of the object on each request is too timecost-consuming. With my still somewhat limited Zope knowledge, I would say it sounds like you should have a look at utilities. regards, Achim Do you mean: Global Utilities? Then I have a question: global utility is not persistent. But can the G.U. create the object, return it to the local object (some container), and local object inserts it somewhere into it? In other words: can this global utility serve as factory of objects which then are added to a container and persisted? Sorry for such a naive question... I still cannot feel fully Zope's persistence mechanism... ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Hi Philip. Sorry for the oblique question. I am using zope interfaces in a project outside of zope and looking at how I might use some of other bits of zope's functionality. Many thanks.

Re: [Zope3-Users] How do I get formlib to play nice with NameChooser
Never mind it was a user error on my part. I was stuffing the data variables in the create function into the context not the object being created. Oooops :) On Fri, 26 May 2006 13:02:42 -0500, mats.nordgren wrote I've been trying to use NameChooser with formlibs AddForm and it always tells me An empty name was provided. Names cannot be empty. I suspect it has to do with set_before_add as my object comes in to the NameChooser without data. Problem is that you define formlib forms with page and set_before_add is in addform. Anyone got this to work?

It requires 3 args in its constructor which you can wrap for formlib, e.g. class MyMultiSelectWidget(MultiSelectWidget): def __init__(self, field, request): super(MyMultiSelectWidget, self).__init__( field, field.value_type.vocabulary, request) Then .. form_fields['multichoice'].custom_widget=MyMultiSelectWidget You could also look at the alternative widget.. zope.app.form.browser.itemswidgets.MultiCheckBoxWidget ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
