Would someone mind describing to me how subpages work in formlib or send me a link to some good docs or a good example? To express my use-case, I have a default view for my content type mapped as index.html (it extends form.DisplayForm). On that view I currently display all of the relevant data regarding my content object which is the context. What I would like to do is add a sub-form to that page for quickly adding child objects so that the user doesn't have to click to another tab or something similar to add their content. Basically a shortcut add form. This *seems* like where subpages might come into play, but alas I do not understand subpages. But perhaps I'm looking down the wrong hole?

Ah... I was thinking that part was some sort of generic example.
Alright, I added that code and now my component

makes some changes to the fields and try to save my changes I get one
of these:
ForbiddenAttribute: ('street', simple_abook.entry.ABookEntry object

Anytime I've seen this in the past it means there's a permission
problem. So I played with the security setting in configure.zcml
some but I could not find anything that helped.
Judging from the error message it looks like it's trying to look up
the security settings for street in entry.ABookEntry. Which would
kinda makes sense, and then it should be looking instead in
entry.StreetAddress, but I don't know how to make it do that. I'll
include my code again too.

However there are a few error I found in your example you may be interested in fixing: in your interfaces.py file you probably want the IPhoneBookEntry interface to look like this: [...] Sorry for the Typo - corrected it. But the whole concept works for me - I'm using schema.Object, too. Maybe I can help - what's the problem? I'm still getting a ComponentLookupError. I'll just include the example I'm trying to make work at the bottom, it's pretty short. I'm beginning to think there may be something in your explication that I need to understand.

[Zope3-Users] zope.schema.Object and custom widgets in formlib
hi there I am having trouble getting form's generated for zope.schema.Object. After doing some more reading it looks like I should be using formlib instead of zope.app.form.browser.add.AddView and zope.app.form.browser.editview.EditView (my new code will be at the bottom) Which is fine because I was really having trouble getting zope.schema.Object to work properly. Of course, now I am running into the same basic problem with formlib. It looks like I need to specify some sort of custom widget for my zope.schema.Object. If I don't I get the same ComponentLookupError I was getting with the old system. I tried the zope.app.form.CustomWidgetFactory, and that actually got that part of the form to show up but it didn't work right. If someone could tell me what I should be doing that would be great. Also one other kinda bizarre thing, in my formlib form all the button text and messages where in German (I think, my German is a little rusty). An aside... I have been really surprised by the lack of other people having the same problems or working examples else where. I think I'm trying to do something very basic that would come up in lots of applications. This makes me think that I'm going about this the wrong way, or the solution is very simple and I'm just being too dense to get it. So basically, if anyone out there has some commentary on my approach to this problem I would really appreciate it. thanks. -jachin # -=interfaces.py=- from zope.interface import Interface from zope.schema import TextLine, Int, Object class IStreetAddress(Interface): A street address street = TextLine( title=ustreet, description=u, required=False) class IABookEntry(Interface): An address book entry streetAddress = Object( schema=IStreetAddress, title=uStreet Address, description=u, required=False) firstName = TextLine( title=uFirst Name, description=u, required=False) # -=entry.py=- from zope.interface import implements from zope.formlib import form from zope.schema.fieldproperty import FieldProperty from zope.app.form import CustomWidgetFactory from zope.app.form.browser import ObjectWidget from persistent import Persistent from interfaces import IStreetAddress from interfaces import IABookEntry class StreetAddress(Persistent): The Street Address object. implements(IStreetAddress) class ABookEntry(Persistent): The Address Book Entry object. implements(IABookEntry) streetAddress = StreetAddress firstName = u class ABookEntryEditView(form.EditForm): form_fields = form.Fields(IABookEntry) form_fields[streetAddress].custom_widget = what should go here? !-- -=configure.zcml=- -- configure xmlns=http://namespaces.zope.org/zope; xmlns:browser=http://namespaces.zope.org/browser; content class=.entry.StreetAddress require permission=zope.View interface=.interfaces.IStreetAddress / require permission=zope.ManageContent set_schema=.interfaces.IStreetAddress / /content content class=.entry.ABookEntry require permission=zope.View interface=.interfaces.IABookEntry / require permission=zope.ManageContent set_schema=.interfaces.IABookEntry / /content browser:page for=.entry.IABookEntry name=index.html template=entry.pt class=.entry.ABookEntry permission=zope.Public / browser:page for=.entry.IABookEntry name=edit.html template=edit.pt class=.entry.ABookEntryEditView menu=zmi_views title=Edit permission=zope.ManageContent / browser:addMenuItem title=ABook Entry class=.entry.ABookEntry permission=zope.ManageContent / /configure !-- -=entry.pt=- -- html metal:use-macro=context/@@standard_macros/view body div metal:fill-slot=body tal:content=view /div /body /html !-- -=edit.pt=- -- html

I think this is saying that it can't adapt my Person object to the
IPerson interface.
Am I still missing something?

[Zope3-Users] ComponentLookupError
hi there here's a smaller, hopefully more clearer example of a problem I have been stuck on. I should probably also lead off by saying that I think what I am asking is basically this question. http://www.mail-archive.com/zope3-users@zope.org/msg00052.html However I have read objectwidget.txt( http://svn.zope.org/Zope3/trunk/ src/zope/app/form/browser/objectwidget.txt ) several times and I don't see where a custom widget gets created. I also suspect that because the object I need to create a custom widget for has more than just one field I have to do something different. If there's a short fix for the problem that would be great, otherwise a little explanation to point me in the right direction would be greatly appreciated too. thanks. -jachin Here's the error I'm getting any my code: 2006-05-11T11:56:47 ERROR SiteError http://localhost:8080/@@+/ action.html Traceback (most recent call last): File /usr/local/Zope-3.2.1/lib/python/zope/publisher/publish.py, line 138, in publish result = publication.callObject(request, object) File /usr/local/Zope-3.2.1/lib/python/zope/app/publication/ zopepublication.py, line 161, in callObject return mapply(ob, request.getPositionalArguments(), request) File /usr/local/Zope-3.2.1/lib/python/zope/publisher/publish.py, line 113, in mapply return debug_call(object, args) File /usr/local/Zope-3.2.1/lib/python/zope/publisher/publish.py, line 119, in debug_call return object(*args) File /usr/local/Zope-3.2.1/lib/python/zope/app/container/browser/ adding.py, line 128, in action name=view_name) is not None: File /usr/local/Zope-3.2.1/lib/python/zope/component/ __init__.py, line 165, in queryMultiAdapter return sitemanager.queryMultiAdapter(objects, interface, name, default) File /usr/local/Zope-3.2.1/lib/python/zope/component/site.py, line 75, in queryMultiAdapter default) File /usr/local/Zope-3.2.1/lib/python/zope/interface/adapter.py, line 475, in queryMultiAdapter return factory(*objects) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/browser/ editview.py, line 64, in __init__ self._setUpWidgets() File /usr/local/Zope-3.2.1/lib/python/zope/app/form/browser/ add.py, line 49, in _setUpWidgets setUpWidgets(self, self.schema, IInputWidget, names=self.fieldNames) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/utility.py, line 153, in setUpWidgets context=context) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/utility.py, line 97, in setUpWidget widget = _createWidget(context, field, viewType, view.request) File /usr/local/Zope-3.2.1/lib/python/zope/app/form/utility.py, line 65, in _createWidget return zapi.getMultiAdapter((field, request), viewType) File /usr/local/Zope-3.2.1/lib/python/zope/component/ __init__.py, line 154, in getMultiAdapter raise ComponentLookupError(objects, interface, name) ComponentLookupError: ((zope.schema._field.Object object at 0x4282b70, zope.publisher.browser.BrowserRequest instance URL=http://localhost:8080/@@+/action.html), InterfaceClass zope.app.form.interfaces.IInputWidget, u'') 127.0.0.1 - - [11/May/2006:11:56:47 -0500] GET /@@+/action.html? type_name=AddPerson.html HTTP/1.1 500 84 http://localhost:8080/ @@contents.html Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en- US; rv:1.8.0.3) Gecko/20060427 Camino/1.0.1 interfaces.py from zope.interface import Interface import zope.schema class IStreetAddress(Interface): A vine street address street = zope.schema.Text ( title=uStreet 1, description=uThe street address, required = False ) city = zope.schema.TextLine ( title=uCity, description=uThe city., required = False ) state = zope.schema.TextLine ( title=uState, description=uThe state., required = False ) zipcode = zope.schema.TextLine ( title=uZip Code, description=uThe zip code, required = False, min_length = 5 ) class IPerson(Interface): firstName = zope.schema.TextLine ( title=uFirst Name, description=uThe person's first name, required=False ) lastName = zope.schema.TextLine ( title=uLast Name, description=uThe person's last name, required=False ) address = zope.schema.Object ( title=uAddress, description=uThe person's adderess, required=False, schema = IStreetAddress ) person.py from persistent import Persistent from zope.interface import implements from

Re: [Zope3-Users] has a relationships
hi there Alright... I'm working on implementing IPerson in the class Person and I'm not sure exactly what has to happen. I kinda have two ideas but I suspect I need to some how combine them but I don't know how to do that. A big part of the problem is that I do not know what zope.schema.fieldproperty.FieldProperty does. The only reason I'm working it in, is because it appears to be necessary to get this whole thing to work: http://svn.zope.org/Zope3/trunk/src/zope/app/form/browser/ objectwidget.txt Here are my ideas: -- from persistent import Persistent from zope.interface import implements from abook.interfaces import IPerson class Person(Persistent): implements(IPerson) firstName = u lastName = u phoneNumbers = persistent.dict.PersistentDict() emails = persistent.dict.PersistentDict() addresses = persistent.dict.PersistentDict() -- from persistent import Persistent from zope.interface import implements from zope.schema.fieldproperty import FieldProperty from abook.interfaces import IStreetAddress from abook.interfaces import IPerson class Person(Persistent): implements(IPerson) phoneNumbers = FieldProperty(IPerson['phoneNumbers']) emails = FieldProperty(IPerson['emails']) addresses = FieldProperty(IPerson['addresses']) def __init__(self, firstName = u, lastName = u, phoneNumbers = None, emails = None, addresses = None): self.firstName = firstName self.lastName = lastName self.phoneNumbers = phoneNumbers self.emails = emails self.addresses = addresses -- I guess my question is, how should I be implementing Person? Is one of those right or are they both wrong? thanks -jachin #abook/interfaces.py from zope.interface import Interface import zope.schema class IStreetAddress(Interface): A vine street address street = zope.schema.Text ( title=uStreet 1, description=uThe street address, required = False ) city = zope.schema.TextLine ( title=uCity, description=uThe city., required = False ) state = zope.schema.TextLine ( title=uState, description=uThe state., required = False ) zipcode = zope.schema.TextLine ( title=uZip Code, description=uThe zip code, required = False, min_length = 5 ) class IABookEntry(Interface): phoneNumbers = zope.schema.Dict( title=uPhone Numbers, description=uThe phone numbers for this entry, required=False, key_type=zope.schema.TextLine ( title=uType, description=uThe type of phone number, required=True ), value_type=zope.schema.TextLine ( title=uNumber, description=uThe phone number., required=True ) ) emails = zope.schema.Dict( title=uEmail Addresses, description=uThe email addresses for this entry, required=False, key_type=zope.schema.TextLine ( title=uType, description=uThe type of email address, required=True ), value_type=zope.schema.TextLine ( title=uEmail Address, description=uThe email address., required=True ) ) addresses = zope.schema.Dict( title=uAddresses, description=uStreet address, required=False, key_type=zope.schema.TextLine( title=uType, description=uThe type of street address, required=True ), value_type=zope.schema.Object ( title=uStreet Address, description=uA street address, required=True, schema=IStreetAddress ) ) class
[Zope3-Users] has a relationships
hi there I have another zope theory question. I am working on designing a application in zope. I've been looking at a lot of examples and I am wondering how people are implementing different types of relationships between different persistent objects. For instance I am going to be doing a lot with addresses. Naturally it would be nice to have persistent Address class. Then I would say that a Person has an Address and a Company has an Address. My two different ideas are as follows: 1. Make Person and and Company containers that can each contain an Address. I don't really like this idea because it seems like container objects are for things like folders. This could be the best way though and I'm just not zoppie enough yet. 2. Add an Object for the Address to the schema for IPerson and ICompany (assuming I only need one address) or a List / Dict (if I want more than one address for each person or company). I like this idea better but I have yet to see any examples where someone does that which is making me a little nervous. Among other things I'd like to be able to see what happens when addforms and editforms get generated for things like this or at least be assured that's the way it is supposed to work. I just got my very own copies of the Zope 3 Developers Handbook and Web Component Development with Zope 3 (I'd suggest these books to anyone by the way). I have given each a once over as well as looking at lots of shorter tutorials / examples online and have not noticed any example projects doing anything like my second idea. So in your answer please feel free to point out something in either of those books (I may have missed) or refer me to some other online example where something like this is going on. thanks -jachin ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] error headache: __init__() takes exactly 1 argument (3 given)
hi there Thanks for the reply. Removing the class attribute from the page directive got rid of the error. However I'm not overriding the VinePackage class. class VinePackage(BTreeContainer): implements(IVinePackage) title = u Since it is inheriting from BTreeContainer, perhaps that overrides the constructor? I'll look into it and if I find an answer before someone else offers one I'll post it. -jachin On Apr 27, 2006, at 3:35 PM, Bernd Dorn wrote: did you override the constructor in vine.vinePackage.VinePackage or one of its superclasses? iv yes, then you need def __init__(self,context,request): ... as constructor, you can test it by just removing the class attribute of your page directive On 27.04.2006, at 21:08, Jachin Rupe wrote: hi there I've got an error I've been stuck on for several hours now and I know the problem has got to be a very simple one but the error message I'm getting is not helping.

[Zope3-Users] Container base classes
hi there I am new to Zope. I have been spending the last several days reading everything I can find on Zope. So far a lot of the larger examples I've seen use zope.app.container.btree.BTreeContainer any time it is necessary to hold a bunch of other objects. Yet when I looked at the documentation for BTreeContainer it says that I probably shouldn't be using it and should be doing something else. Assuming I know enough now to start working on a real project, should I be sticking with the stuff in the persistent package? Are there other persistent objects hiding somewhere else in the API I should be aware of? thanks -jachin ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] Security Question
hi there Is there a good example out there of setting up security based on some sort of ownership system? I'm working my way though the Zope book. What I would like to be able to do is allow the User who created a message to edit only their messages (the messages they created). I think I've read all the relevant chapters of the Zope book and I can't find a place where it explains that. Did I miss is somewhere? Could some one point me in the right direction for figuring this out? If this isn't in the Zope book it may make a good addition. There are lots of instances I can think of in application where someone would want to grant privileges based on ownership. thanks -jachin ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
