[Zope3-Users] Virtualenv, zopeproject, MinGW and Windows
I'm reposting this as my original post was buried in another thread. I've managed to get the zopeproject to work correctly on my Windows box thanks to the easy to follow instructions on the PyPI page for it. Next I tried to do a "python setup.py install" which, I was informed, is generally a bad idea to do and was suggested to use "virtualenv" to keep my global python nice and clean. So I easy_installed virtualenv and making that work was a simple task. But once I'm inside my virtual environment, I can no longer get the zopeproject to compile the C extensions.

[Zope3-Users] zope.app.session and eggs?
I finally got the courage to try the eggs install on Windows after reading the documentation on zopeproject. It worked great and I have my brand new project working. Now here is the problem. I'm assuming a "python setup.py install" will download all the parts and install it into my python site-packages directory as that seems to be what it is doing. But I get an error when i get to the zope.app.session package. Here is the trace. Now I'm not sure why it is trying to get the 3.4 version as the zopeproject downloaded the 3.5dev. Can someone shed some light on this?

Stephan,
Thanks again for you help.
I'm still having the ErrorViewSnippet problem. I've gone over and over the
message example in formdemo and can't see anything different in my setup
from the demo. The demo works fine but mine throws the ErrorViewSnippet
error when I submit an AddForm with missing input. EditForm works correct
though.
Here is the full traceback. I'll also include the browser files at the end.

RE: [Zope3-Users] z3c.form and subforms in an AddForm?
Thanks Stephan, I have now got the sub form to render in browser. Much appreciated. A few more questions though. In the create method, the data is only the parent data. The self.widgets.extract() returns only parent data. The only place I see the sub form data is in self.request.form. What is the best way to extract the data and create your object? Perhaps unrelated but I had this working before. I'm using formui and I'm getting a "TraversalError: (, 'widget')". I tried to trim out all the sub-form stuff I've messed around with and replaced a simple object with two textlines one of which is required. This happens when I'm submitting the form without an entry in required field. With data it works just fine and adds the object. The addform is using the macro:form from formui. Any ideas as to where this comes from and how I can fix it?

Roger,
> You missed in the AddressAddForm ``self.widgets.ignoreContext = True``
I see that I missed that statement, it was late on a sleepless night, but I
couldn't get this out of my head. In any case, I've changed my code to
match the example you gave in the repository. I also have the templates
defined in the view instead of through zcml as you have in the tests.
browser/restaurant.py
class RestaurantAddForm(form.EditForm):
"""Add form"""
fields = field.Fields(IRestaurant).select('name', 'description')
template = viewpagetemplatefile.ViewPageTemplateFile('restaurant.pt')
prefix = u'restaurant'
def updateWidgets(self):
self.widgets = component.getMultiAdapter((
self, self.request, self.getContent()), IWidgets)
self.widgets.ignoreContext = True
self.widgets.update()
def update(self):
self.address = AddressAddForm(None, self.request)
self.address.update()
super(RestaurantAddForm, self).update()
browser/address.py
class AddressAddForm(form.EditForm):
fields = field.Fields(IAddress)
template = viewpagetemplatefile.ViewPageTemplateFile('address.pt')
prefix = u'address'
def updateWidgets(self):
self.widgets = component.getMultiAdapter((
self, self.request, self.getContent()), IWidgets)
self.widgets.ingoreContext = True
self.widgets.update()
browser/configure.zcml
I believe those matches your example exactly but I still get the adaption
error when the form should be displayed.

Not sure I'm understanding this, your example used EditForm without any
thought on superclasses.
Again thanks for all your time and effort, I really appreciate this.

Re: [Zope3-Users] AW: z3c.form and subforms in an AddForm?
Roger,
Thanks for your reply. I'm still having problems getting this to work.
I'm not sure I am supposed to use a BaseForm, Form, AddForm, or what, for
the sub-item. I'm not sure how to register it in zcml to not get adaption
errors when I run it.
Would there be any chance to have the example with the "car" and "owner" in
the Sub-Form doc test included in the formdemo package. I'd like to see
that included with "Class I" and "Class II" for both AddForm and EditForm
since it is such a common use case.
Perhaps I'm just dense, but I still have problems converting doc tests into
an actual working zope instance. The formdemo package was a god send to get
a simple addform working since I had no idea you needed to use the
IFormLayer. Using the demo that was no longer a problem.
Again thanks for all your help.

RE: [Zope3-Users] assigning roles to principals onAuthenticatedPrincipalCreated event
As I understand a principal is created and destroyed with each request.
This would make your application set the permission at each request which
might not be exactly what you had in mind. I use a group folder from pau
and set the group with a subscriber when the site object is created.
def SiteCreatedHandler(context, event):
...
sm = LocalSiteManager(context)
context.setSiteManager(sm)
setSite(context)
default = sm['default']
pau = PluggableAuthentication(prefix='pau.')
default['pau'] = pau
sm.registerUtility(pau, provided=IAuthentication)
groups = GroupFolder(prefix='groups.')
pau['groups'] = groups
sm.registerUtility(groups, provided=IAuthenticatorPlugin, name='groups')
members = GroupInformation('members')
groups['members'] = members
sm.registerUtility(members, provided=IGroupInformation, name='members')
principals = PrincipalFolder(prefix='principals.')
pau['principals'] = principals
sm.registerUtility(principals, provided=IAuthenticatorPlugin, \
name='principals')
principal_roles = IPrincipalRoleManager(context)
principal_roles.assignRoleToPrincipal(u'metrod.Member', \
'pau.groups.members')
Then when a new member sign up I add them to the group i.e. 'member'. I do
this in the createAndAdd method of formlibs AddForm.
def createAndAdd(self, data):
name = data['name']
password = data['password']
pau = getUtility(IAuthentication, context=self.context)
principals = getUtility(IAuthenticatorPlugin, name='principals', \
context=self.context)
principal = InternalPrincipal(name, password, name)
principals[name] = principal
groups = getUtility(IGroupInformation, name='members', \
context=self.context)
groups.principals += (pau.prefix + principals.prefix + name, )
return self.request.response.redirect('.')
Not sure this is the best way to do it but it works for me. One thing I did
see in your code though is:
prm.assignRoleToPrincipal('isi.member', event.principal)
which should be:
prm.assignRoleToPrincipal('isi.member', event.principal.id)

Subject: [Zope3-Users] assigning roles to principals
onAuthenticatedPrincipalCreated event
Hello zope3-users,
I am trying to do make easy user registrations for my website. but I am
having problems assigning roles to the principals automatically.
the question is WHEN should I assign these roles to the new principals?
which is the standard procedure?
right now I am doing :
1. User accounts (InternalPrincipal) are created.
2. The first time the user logs in a role with id="isi.member" will be
assigned to it on the whole site so the user receives membership
permissions.
*configure.zcml*
*userhome.py
class UserLoggedIn(object):
def __init__(self, event):
userAnno=zapi.getUtility(IPrincipalAnnotationUtility,
'ISIUserAnnotation')
annotations=userAnno.getAnnotations(event.principal)
if annotations.get('user_home') is None:
print "***RGISTERING ANNOTATIONS*"
annotations['user_home'] = Folder()
annotations['user_home']['register'] = PersistentDict()
annotations['user_home']['personal'] = Person()
annotations['user_home']['personal'].first='hassan'
annotations['user_home']['personal'].last='alirezaei'
annotations['user_home']['testing'] = "TESTING THE NEW USER"
siteroot=getSite()
prm=IPrincipalRoleManager(siteroot)
print "**for %s ***" %siteroot
prm.assignRoleToPrincipal('isi.member', event.principal)
**
getSite() gives mebut when i
go to this object (my main site root) and change to "Grant" from
zmi_actions menu the role is still unset for the user.
any help is highly appreciated. it is very much possible I am doing the
hard way to perform the task.
Thank you in advance!

RE: [Zope3-Users] Problem with containment and @@absolut_url
Achim,
context/articles would return the id's
>>> d = {'one':1, 'two':2}
>>> for item in d:
... item
...
'one'
'two'
The id is a string which has a title method (capitalize each worlds first
letter); this is why your article/title is working.
>>> for item in d:
... item.title()
...
'One'
'Two'
You probably should use context/articles/values for the loop.
Cheers,
Mats
