[Zope3-Users] Still trying am to build an EditForm
Hello, I am still trying to build an EditForm using z3c.form. Since my previous thread is rather old I dare to open a new one. I've tried a number of variations and will post the one which is the closest to the example. This is the interface: class IBlogEntry(IContainer): Interface for blog entry objects. contains(IBlogComment) title = TextLine( title = _(uBlog entry title), description = _(uBlog entry title.), default = u, required = True) content = Text( title = _(uBlog entry content), description = _(uBlog entry content.), default = u, required = True) inputType = Choice( title = _(uType of input), description = _(uSpecify the input type), required = True, default = ureStructeredText, values = [ureStructeredText, uHTML] ) The view is configured like that: z3c:pagelet name=EditEntry.html for=..interfaces.IBlogEntry class=.views.EditEntry permission=Blog.EditEntry layer=Blog.interfaces.IBlogLayer / The code in .views.EditEntry is: class EditEntry(layout.FormLayoutSupport, form.EditForm): fields = field.Fields(IBlogEntry).select(title, content) The layer is registered like that: interface interface=.interfaces.IBlogLayer name=BlogSkin type=zope.publisher.interfaces.browser.IBrowserSkinType / and class IBlogLayer(IFormLayer, IPageletBrowserLayer): Demo browser layer using div-form layout template. Now I call the URL. http://localhost:8080/++skin++BlogSkin/Blog/2007_08_16_abc/EditEntry 2007_08_16_abc ist an BlogEntry object. Now there comes an ComponentLookupError. A server error occurred. up. Traceback (most recent call last): Module zope.publisher.publish, line 133, in publish result = publication.callObject(request, obj) Module zope.app.publication.zopepublication, line 167, in callObject return mapply(ob, request.getPositionalArguments(), request) Module zope.publisher.publish, line 108, in mapply return debug_call(obj, args) - __traceback_info__: security proxied z3c.pagelet.zcml.EditEntry instance at 0xa0248cc Module zope.publisher.publish, line 114, in debug_call return obj(*args) Module z3c.formui.layout, line 27, in __call__ ILayoutTemplate) Module zope.component._api, line 103, in getMultiAdapter raise ComponentLookupError(objects, interface, name) ComponentLookupError: ((z3c.pagelet.zcml.EditEntry object at 0xa0248cc, zope.publisher.browser.BrowserRequest instance URL=http://localhost:8080/++skin++BlogSkin/Blog/2007_08_16_abc/EditEntry.html), InterfaceClass z3c.template.interfaces.ILayoutTemplate, u'') I have also tried some variations of the above like not using z3c:pagelet but an normal page directive, registered it without an layer directive and so on.

Hello,
I try to create an edit form with z3c.form but it gives me an
system error only:

Try to find out which field doesn't have a widget. This is
probably the __parent__ attribute.
My code looks like that:
from z3c.form import form, field
from z3c.formui import layout
class EditEntry(layout.FormLayoutSupport, form.EditForm):
fields = field.Fields(IBlogEntry)
Try to restrict your fields and find out which one does not
have a widget with:

Hi!
I changed it to:
class EditEntry(layout.FormLayoutSupport, form.EditForm):
fields = field.Fields(IBlogEntry).select(title, content)
but which doesn't change the error. This is the interface I get the fields
from:
class IBlogEntry(IContainer):

contains(IBlogComment)
title = TextLine(
title = _(uBlog entry title),
description = _(uBlog entry title.),
default = u,

[Zope3-Users] Building an admin interface
Hello, I have a rather fundamental problem. Until now the editor of my bloggin software has added, modified and removed blog entries by logging in to the ZMI and use the filesystem like view there. This gives me (as the developer) only very limited control about how it is done. For example: A newly created entry should be stored in the subfolder year/month/day/entry_id. I can modify the entry_id by using a NamesChooser adapter but I can't (AFAIK) modify the actual location. Because of this I want to develop an admin interface. The application generally shoud work stand alone (eg. not integrated in Plone) but should act as a well behaving citizen in the Zope3 world. (make integration easy). How is this done the best way? - What skins to use? - How should authentication be done? Just rely on the authentication source being around and use it with getUtility(IAuthentication)? - How to design my ZPTs to make them fit in the skin/interface? - What else to pay attention to?

The naming scheme is like 2007_07_05_Title_of_entry example: [1] But that is not something I really like and I think it will be unhandleable for large blogs.

Oh, my, this feels like cargo-cult programming[1] to me. For example,
zope.app.testing.setup.placelessSetUp() calls
zope.app.container.tests.placelesssetup.PlacelessSetup().setUp() for you
already, you don't need to do it twice. In fact the
CleanUp().cleanUp(), which is the first thing that placelessSetUp()
calls, undoes all the changfes made by container_setup.setUp(). The
same applies to zope.component.testing.setUp.

You're probably right about that, I've very little experience with the testing
framework.
I would suggest that you remove everything and keep just
def blogSetUp(test):
zope.testing.module.setUp(test, 'Blog.doctest')
it worked after I've added the line above.
setup.placelessSetUp()
setup.setUpTraversal()
def blogTearDown(test):
setup.placelessTearDown()
and this is my README.txt containing the test:
context = MyBlog
You may want to actually create the object:
context = MyBlog()
MyBlog is the instance.
and sometimes it is a good idea to put it into the containment
hierarchy, if you're going to look up things like absolute URLs:
from zope.app.folder import rootFolder
root = rootFolder()
root['my_blog'] = context
from zope.publisher.browser import TestRequest
from browser.views import RSSFeed
request = TestRequest()
view = RSSFeed(context, request)
print view()
Since my code includes a call to absoluteURL I have added your setup and
tearDown methods. But there is still an error:
Thanks, now it works!
BTW: What would be the name of the MyViewClass if the page would be
registered without a class set?
There isn't one. When you use the browser:page directive, the ZCML
maaagick creates a new class (with a funky name) at runtime, with extra
attributes and methods. You cannot access that class from a unit test,
because it doesn't exist in your source code.
My suggestion is don't do that. If you want a view with just a
template, and you want to render it in a unit test, define a view class
class MyTrivialViewClass(BrowserPage):
__call__ = ViewPageTemplateFile('mytemplate.pt')

In a unit test you can do it like this:
context = ...yourcontentobject...
from zope.publisher.browser import TestRequest
request = TestRequest()
view = MyViewClass(context, request)
print view()
some xml or whatever output here
If you want to provide, e.g., form parameters, pass them to the request:
request = TestRequest(form={'foo': u'Lalala\u1234'})
If your view does anything interesting (e.g. use TALES expressions, or
refer to other views like context/@@absolute_url), you will need to
register a whole bunch of components in your doctest setUp methods.
Don't forget to tear them down afterwards. IIRC you will need
from zope.app.testing import setup
def setUp(test):
setup.placelessSetUp()
setup.setUpTraversal()
def tearDown(test):
setup.placelessTearDown()
at the very least. Accessing other views, resources, or, god forbid,
forms, will require other component registrations. At some point you
have two choices: figure out this stuff once and then use copy paste
(actually, helper functions defined once in your project), or switch to
testing your views with functional tests.

there would be no text at all, but I want the raw to be treated just like
any other
text.
If you want to preserve the raw command, how about swaping the 'raw::'
directive for a placeholder (eg. ||rw|| ), process the ReST data normally,
then swap the 'raw::' command back in place of the placeholder?
I've found out it could partly be achieved by using:
def convertToHTML(self, comment):
Converts a comment from restructured text to HTML.
text = unicode(comment.content)
settings_override = {}
settings_override[raw_enabled] = False
settings_override[file_insertion_enabled] = False
# settings_override[report_level] = quiet
renderer = ReStructuredTextToHTMLRenderer(text, self.request)
return renderer.render(settings_override).strip()
but now a raw directive generates an error message whereas it is completely
swallowed when uncommenting the report_level.

Florian

[Zope3-Users] Still a skinning problem
Hello,
I am doing a repost here, since the problem really bugs me and I have gotten
no replys anymore...
I have a template template.pt which should be applied to all site visited
within the skin xgm.
page
for=*
name=standard_macros
permission=zope.Public
class=.views.StandardMacros
layer=xgm.interfaces.IXGMSkin
allowed_interface=zope.interface.common.mapping.IItemMapping
/
page
for=*
name=skin_macros
permission=zope.Public
layer=xgm.interfaces.IXGMSkin
template=template.pt
/
and
class StandardMacros(BaseMacros):
macro_pages = ('skin_macros', )
the template.pt is the one also used on xgm.de:
metal:block define-macro=page
metal:block define-macro=view
html xmlns=http://www.w3.org/1999/xhtml; xml:lang=de lang=de
head
title metal:define-slot=titleTesttitle/title
link rel=stylesheet type=text/css tal:attributes=href
context/++resource++files/styles.css /
/head
body
ul id=navigation
li[ a tal:attributes=href
context/@@index.html/@@absolute_urlhome/a ]/li
/ul
div id=content
metal:block define-slot=body
This is the content.
/metal:block
/div
/body
/html
/metal:block
/metal:block
(shortened a bit)
index.html is registered like that:
pages
for=xgm.interfaces.IXGM
layer=xgm.interfaces.IXGMSkin
permission=zope.Public
class=.views.ViewClass
page
name=index.html
template=index.pt /
/pages
This works perfect as far as only pages use this template who are registered
on the same interface like the other ines (IXGM).
Now I have a third party package (Blog) which should generally be independent
to all that but should use the template.pt which called with ++skin++xgm.
html metal:use-macro=views/standard_macros/view
body
div metal:fill-slot=body
h1 tal:content=context/title/h1
div tal:content=context/description /
div class=row tal:repeat=item view/getSortedBlogEntries
tal:content=structure item/@@details.html /
/div
/body
/html
is registered on the default layer. Since the xgm layer derives from the
default layer it correctly uses my template.pt.
But the problem is now when a view from the Blog object are called links in
the template like
a tal:attributes=href context/@@index.html/@@absolute_urlhome/a
do not work anymore, since context is the Blog and not a IXGM object anymore.
Therefore the lookup fails.
Sorry for the long mail, I hope I was able to explain what my problem is.

That's no good. The /@@/ view only works when context is a site.
Besides, I'm not sure you can use it in a TALES expression like

You want

I think. (I'm sure href context/++resource++name.css is the right
solution for plain resource files, but I haven't used
resourceDirectory
much.)
It works like that for resourceDirectory resources as well.
Yes, it works fine but now I have another problem:
The tempate contains links like:
Which template?
a tal:attributes=href context/@@contact.html/
@@absolute_urlkontakt/a
contact.html is registered for the interface (IXGM) of the object
in which the
object that should use the template (IBlog) resides. But in the
IBlog context
there is no contact.html.
What is the best way to work around this?
- Register contact HTML for all interfaces?
- Make them static (no TAL) links?
Both are ways I don't really like.
I'm not getting this. Before you asked about resources, now all of a
sudden it's about a template?
Ok, the entire situation is:
I have a template template.pt which should be applied to all site watched in
the skin xgm.
page
for=*
name=standard_macros
permission=zope.Public
class=.views.StandardMacros
layer=xgm.interfaces.IXGMSkin
allowed_interface=zope.interface.common.mapping.IItemMapping
/
page
for=*
name=skin_macros
permission=zope.Public
layer=xgm.interfaces.IXGMSkin
template=template.pt
/
and
class StandardMacros(BaseMacros):
macro_pages = ('skin_macros', )
the template.pt is the one also used on xgm.de:
metal:block define-macro=page
metal:block define-macro=view
html xmlns=http://www.w3.org/1999/xhtml; xml:lang=de lang=de
head
title metal:define-slot=titleTesttitle/title
link rel=stylesheet type=text/css tal:attributes=href
context/++resource++files/styles.css /
/head
body
ul id=navigation
li[ a tal:attributes=href
context/@@index.html/@@absolute_urlhome/a ]/li
/ul
div id=content
metal:block define-slot=body
This is the content.
/metal:block
/div
/body
/html
/metal:block
/metal:block
(shortened a bit)
The styles.css is the ressource my last posts were about.
index.html is registered like that:
pages
for=xgm.interfaces.IXGM
layer=xgm.interfaces.IXGMSkin
permission=zope.Public
class=.views.ViewClass
page
name=index.html
template=index.pt /
/pages
This works perfect as far as only pages use this template who are registered
on the same interface like the other ines (IXGM).
Now I have a third party package (Blog) which should generally be independent
to all that but should use the template.pt which called with ++skin++xgm.
html metal:use-macro=views/standard_macros/view
body
div metal:fill-slot=body
h1 tal:content=context/title/h1
div tal:content=context/description /
div class=row tal:repeat=item view/getSortedBlogEntries
tal:content=structure item/@@details.html /
/div
/body
/html
is registered on the default layer. Since the xgm layer derives from the
default layer it correctly uses my template.pt.
But the problem is now when a view from the Blog object are called links in
the template like
a tal:attributes=href context/@@index.html/@@absolute_urlhome/a
do not work anymore, since context is the Blog and not a IXGM object anymore.
Therefore the lookup fails.
Sorry for the long mail, I hope I was able to explain what my problem is.

Re: [Zope3-Users] Periodically refresh RSS feeds
Am Dienstag, 19. Dezember 2006 08:17 schrieb Christian Theune: Hi, Florian Lindner wrote: Hello, I have the following situation: An object represents an RSS feed. It should be updated like every 20 minutes. If there is something new a Jabber message should be send out. Currently I have it implemented with an scheduler loop that emits an refreshRSSFeed event evey 20 minutes. My problem is that a handler for an event must be a static function, but I want a handler function to be called as a member of every instantiated RSS feed object. Another idea I have: Implement an utility where the RSS feeds could register a function that is called every 20 minutes. Another way would be that this utility takes an URL and monitors the URL for changes and only notifies the RSS Feed object in case of a change. How would you do that? So there's two problems here: scheduling and notifying persistent objects about an event. No, only the notifying problem. I don't have a good idea about the scheduling right now, except the hint that using a 'zopectl run' script might be worthwhile. I'm not sure what a 'scheduler function is'. I use the scheduler package from the Zope3 trunk and so far it works for me. About notifying persistent objects: There is a method 'getAllUtilitiesRegisteredFor(interface)' which might help you. Have a look at zope/app/catalog/catalog.py beginning from line 150 (indexDocSubscriber) how the catalog handles events and dispatches them to multiple catalogs. I think this pretty much matches your use case if you make each RSS feed a (named) utility. The RSS feed is a object that users could add and remove to arbitrary (sub-folders of there home-dir) folders. I would rather regard it as content object and I don't like adding utilities to content space (I have never really understood why content- and software-space have been mixed up). It would be possible, I think even technically superior to the next solution but somehome I don't like. Of course you could also have a utility that maintains references to all RSS feed objects and simply loops over them and calls a method for refreshing. That's something I had mentioned in my posting too. It has advantage that the feeds could decide if they want to be called or not, whereas by the utility-way they would always be called.

You know, this is probably due to a new mechanize version. You would have
to update the scripts probably to the latest mechanize.
I've managed to fix the script so far that it works with the OnlineBrowser()
(self.browser = OnlineBrowser()).
If I use the PublisherBrowser() I get a ConfigurationError:

Should I modify it in a way that it always uses the OnlineBrowser() and check

Maybe I will have time to look into the problem with PublisherBrowser() but I
doubt so since is examina time in university...

If I simply replace self.context by the object I got from UserPreferences it complains about PreferenceGroup being not adaptable to IUserSettings (and it's right about that). Sounds like you want to create an adapter. The adapter is what's used for getting/setting values. I also thought about that. But if I write an adapter from PreferenceGroup to IUserSettings to all that the adapter would do is to assign values the values from the PreferenceGroup to IUserSettings. Ok it's more generic but at the end the same like assigned the values to the request itself. Is it okay to change self.context in the __init__ method of the view class with a PreferenceGroup object? (I just didn't know it it's not confusing the something in the ComponentArchitecture...) Of course I need to initialize the from with the values from the the PreferenceGroup object. Is there a better way than modifying the request like request.form['form.max_size'] for each field? I couldn't find one in the documentation but I'm almost sure there is a more elegant solution (since it's Zope!). Did you look at the get_rendered argument to zope.formlib.form.FormField?

[Zope3-Users] Calling method of superclass
Hello, should be a simple problem, but... I have a class that is registered as a NameChooser: from zope.app.container.contained import NameChooser class XGMNameChooser(NameChooser): implements(INameChooser) def chooseName(self, name, object): if IAbbreviation.providedBy(object): [...] return n else: return super(NameChooser, self).chooseName(name, object) I want to take care only of the objects that are of type IAbbrevation. But I can't call the File /home/florian/Desktop/zope/lib/python/xgm/xgm.py, line 35, in chooseName return super(NameChooser, self).chooseName(name, object) AttributeError: 'super' object has no attribute 'chooseName' What am I doing wrong?

Have a look at http://zope3.mpg.de/suchen (Das Prinzip) You can get the IntIDs utility to register objects after they are created. Something like the below will register and catalog a bunch of items: def catalog_items(self): intids = zapi.getUtility(IIntIds,[name]) catalog = zapi.getUtility(ICatalog,[name]) for item in some_function_that_returns_the_items(): catalog.index_doc(intids.register(item), item) The most important part is the intids.register(item) statement. The problem is not that objects have been created before the IntIDs utility. The IntID utility says that 3 objects are registered, but the catalog indexes are still zero count.

[Zope3-Users] Generating loginForm with formlib
Hello, I want to generate a login form for the PAU session credentials plugin. The plugin expects a form that have a login and a password field. I've created a interface: class ILoginForm(Interface): For generating the login form. login = TextLine(title=uUsername, required=True) password = Password(title=uPassword, required=True) but formlib generates the two fields with name=form.login therefore the session credentials plugin is able to extract the credentials.

Interesting. We did, of course, something similar too in our current project. This either means that (a) PAU is too hard to set up and/or (b) that we need another helper layer. I would like to think the problem is (b), because I like the flexibility of PAU. The configuration package we wrote is step one, but it would be good to agree on a set of high-level helper functions too. I think it's fine the way it is beside one thing. # This is fine, it's added just like all the other utilites. pau = ensureUtility(cs, IPluggableAuthentication, '', PluggableAuthentication , asObject = True) # This is ok for adding, but I got no idea how to register it. A nice thing would be function like ensurePlugin that works analog to ensureUtility (adds und registers a plugin, does the NameChooser call if needed, ...) principal_folder = PrincipalFolder(prefix = cs) pau[PrincipalFolder] = principal_folder # This is pretty straightforward but I was not expecting to give a string, rather I thougt it expected a Interface or something like that. pau.credentialsPlugins = (u'Session Credentials',) The only thing I would change is to add a ensurePlugin function to either the pau object itself or also as part of zope.app.appsetup. (like all the other ensure* functions). Florian ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
