Are there recommendations or experiences how to structure code and test? E.g. at the moment everything lives under Products/TextIndexNG3. Unittest scripts perform imports from Products.TextIndexNG3...which is fine for Zope 2 but properly not for Zope 3. So what the best way to deal with common code on both platforms? I knew this would happen some day, and I have thought for a long time about it already. :-) I think the trick would be to write code for Zope 3 and put it in a top-level package, like textindexng. Inside this package you add a package TextIndexNG that is expected to be added to Zope 2's lib/python/Products. So the tricky part is to not run the tests in textindexng/TextIndexNG when testing from Zope 3's test runner. I could work with you on some testing support for this. So in effect, in Zope 3 you would have: src/textindexng +-- TextIndexNG (not used or even distributed) In Zope 2: lib/python +-- textindexng +-- Products +-- TextIndexNG I think this would be a usable pattern; what do you think?

Correct.
What is the best and most generic way to do that?
This is not so easy, since every queriable could have a different API for
searching. A queriable always describes a search schema. From this search
schema you can build a query mapping that is passed into the search()
function of the queriable. I think you best bet would be to choose the
default value for each field. Here some untested code:
user_ids = []
for name, queriable in pau.getQueriables():
q = {}
for n, f in queriable.schema.namesAndDescriptions():
q[n] = f.default
user_ids += list(queriable.search(q))
users = [pau.getPrincipal(id) for id in user_ids]

In this particular case I would go with sub-classing, though usually I recommend the use of adapters. Basically, if the additional feature you try to implement has to do with the object's behavior in the system, it should be in an adapter. If the feature is characteristic of the object inside any system, it should be directly provided by the object. Regarding the Adapters route, in his book Phillip gives an analogy of Interfaces as a contract that an object uses to promise its functionality. If an Interface promises that an object will have a given method, does it have to provide it directly, or can it use an adapter to provide it? If an object promises it provides an interface it has to do so directly, not via an adapter.

Therefore it will be usefull to use interfaces to build the above classification, but - and that's very important - that does not mean that you transfer this classification directly to your deeper implementation (classes), but you could use *pure* marker interfaces for that classification purpose too. Those pure marker interfaces could mark instances of a generic object implementation [1].

One problem of this method is that I can not really return an validation error of the name field if the name is already taken. AFAIK I can't develop a custom schema field that validates it before, because fields do not have access to their objects. What do you think is the best solution of the problem above?

[Zope3-Users] Freeze approaching quickly
Hi everyone, with October winding down, the freeze on the trunk is coming quickly. So, if you have any outstanding work, now is the time to get it done. During the last week I have monitored the proposals and branches a bit and I think most people are done with their work. After Michael told me that WebDAV has to wait until 3.3., the only outstanding projects are: - Dimitry (hdima): Merge the password manager branch. I know he is close, so I am not worried. - Jim (J1m): Merge the new zope.testing framework. I am not worried about this either. - Stephan and other interested parties (srichter): Finish the static apidoc generator script. I don't know whether I will get done, because I have other things to do. The worst case scenario will be that there is no static apidoc for 3.2. - Roger (projekt01): He mentioned to me that he will fix the Boston skin to the new content provider and viewlet APIs. Since I think that the Boston skin is very pretty and a good show case of the new APIs, I want to include it into the release, if the work is done on Tuesday. Did I miss anyone? Now is the time to speak up! Once the feature freeze is complete, I would like to keep the trunk frozen for about a month, so that the contribution bar for bug fixes remains as low as possible. And bugs we have plenty. As people start using Zope 3, we have had quiet a number of reports, some of which are really serious, like i18nextract being broken. Thus I propose two bug days: - Firday, November 4, 2005 - Friday, December 2, 2005 What do you guys think? Would people commit time on those days to the effort?

Aside: how would i create a default view for a POST request for a certain object ? See the SchoolTool REST interface. It does all those type of things. The tinyu bit longer answer is: Develop a view class that implements a method called POST and then register this method as a view for IHTTPRequest.

Has anyone yet tried sqlos with database connections created as local utilities ? At one point sqlos tries to get the utility in connection.py Line 88. newconn = zapi.queryUtility(IZopeDatabaseAdapter, name, default=None, context=context) The context points to a sqlobject instance. The problem is that these instances seem to have no parent and thus will fail the lookup my local utility and will raise an 'NoneType' object is not callable error later in the code when trying to adapt. When you try the sqlos example everything is fine, since the database connection is defined in configure.zcml as a global utility. My current idea is to expose the enclosing folder as a context to query utility. But I don't know if setting references in sqlobject instances is such a great idea. If the sqlobject instance does not have a parent, then that's bad. It probably does not have a parent, because it is usually wrapped using a location proxy, which is lost inside a method. I think the smart thing to do here would be what you suggested or to write a subclass of sqlobject that implements ILocation.

But I get a little stuck conceptually at the point where I try to handle, for example, the fact that for some ISharedHouse objects, IAccreditationScheme would be suitable, whilst for others it wouldn't, because of their location. In fact it's likely that in the future we will need to recognise two or more standards for a particular accommodation type (so IAccreditationScheme and IHouseCheck chould both apply to ISharedHouse objects, in differect areas). This is not such a complex case as you think. If you register an adapter from ISharedHouse to IAccreditationScheme then it will be only available for this interface and not for IAccommodation in general. I would even write a specific IAccreditationScheme for every scheme you support; thus you do not even need named adapters.

Yeah, you need to deny all permissions to anonymous. Note that then anonymous

no, that's not necessary.

You could do that, if you like.

anybody = zapi.getUtility(IUnauthenticatedPrincipal).id

for permission in self._view_permissions:
pmanager.denyPermissionToPrincipal(permission, anybody)
mmh, that should work though.

[Zope3-Users] Zope 3.2.0 beta 2 released!
The Zope 3 development team is proud to announce Zope 3.2.0 beta 2. Zope 3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. It is our opinion that Zope 3 is more than ready for production use, which is why we decided to drop the 'X' for experimental from the name. We will also continue to work on making the transition between Zope 2 and Zope 3 as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in the form of Five. This is a long term effort. We're not there yet. **You can't run Zope 2 applications in Zope 3.** Downloads http://zope.org/Products/Zope3 Installation instructions for both Windows and Un*x/Linux are now available in the top level 'README.txt' file of the distribution. The binary installer is recommended for Windows. Zope 3.2 requires Python 2.4.2 to run. You must also have zlib installed on your system. Most Important Changes Since 3.2b1 New features - Added an option to mkzopeinstance to create instances that use ZServer, rather than Twisted. - Changed the way returning large results is handled. Applications can now simply return files to the publisher. Bug Fixes - Added input buffering to the twisted integration - Fixed the plumbing in ZServer so that attempts to return large output efficiently using iterators can actually succeed. For a complete list of changes see the 'CHANGES.txt' file.

You can then say, okay, if the macro page was requested, then I do not want to show the available views, context menus, etc. The usage of this feature can be seen in zope.app.rotterdam/template.pt But then in CMF, seemingly using view/page to mean something else, I have: browser:pages versus browser:view And in the source, we have: Named View w/o Pages Unnamed View w/Pages Named View w/Pages First of all, I think you meant to s/CMF/ZCML. Next, ZCML has **nothing** to do with TAL. In ZCML, browser:page and browser:view are ways to register new browser views. I agree that their existence is convoluted, as browser:pages duplicates a lot of the browser:view use cases. If you use browser:view, with pages, then you can do the following traversal: context/view1/page1.html context/view2/page2.html If you use browser:pages, then you can only do: context/page1.html cotnext/page2.html Obviously a page and a view are not the same thing, but something hierarchical. But is such a page still a view component or some appendage of a view? For adding items: +/index.html +/action.html Those are two real browser-pages, one for displaying the form to be filled in, and one for accepting that form and actually creating the item. And some benefit or sharing of data occurs by making those pages 'subviews' of the '+' view but I'm not sure what that benefit is, other than sharing a few ZCML directives. Well, we do not clutter the container namespace. Consider this. Let's take your suggestion and let's implement, adding-index.html and adding-action.html. The you could use: container/@@adding-index.html container/@@adding-action.html There are two disadvantages: (a) You always have to use @@, since the container could have objects called adding-*.html. (b) You have to use more English and it is not as obvious that those two views belong together. And last, in such a sequence of pages, there must be a way to control the final destination or page displayed after creating that instance. One Zope 3 book mentions providing a nextURL() method on the view, but in the case of '+' that would require subclassing. Is there a less intrusive way? Subclassing is fine in this case. You could write your own IAdding implementation that looks up an adapter for the nextURL call, but I think that would be an overkill.

Re: [Zope3-Users] My principals not being found by PrincipalRegistry

Is there something I manually have to do in order to get my principals to be available in the PrincipalRegistry, or have I screwed up somewhere else? This seems strange to me. As long as you implemented all the interfaces correctly (specifically getting the principal's complete id), there should be nothing else required. I suggest looking into the undo code, make some PDB breakpoints and see where you loose the information.

Re: [Zope3-Users] (Ab)using utilities
On Tuesday 29 November 2005 18:16, Thomas Lotze wrote: Our current solution is to register utilities that handle type two and three items, and turn them into folders actually containing the items while we're at it. This does provide uniqueness of the type two and three item containers, as well as well-defined access by an interface name. However, I'm not at all sure that containing application data is what utilities are meant for. Is it? I get a feeling that we might want folders as attributes of the top-level container, for all the uniqueness and well-defined access that provides. But would that be Zope-3-ish? There are several approaches: (1) Use the catalog. I bet you can find a way to create an index by class name or by the content type interface. (2) Write a special folder that keeps track of all ids of type A, B, C... This is the cheap way of getting a catalog-like feature. (3) a derivation of (2) would be to write adapters that store the ids of type A, B, C in annotations. Use event subscribers to update the annotations. Overall, I agree with you that utilities are not meant to solve this type of problem for the reasons you listed yourself.

Re: [Zope3-Users] How to render PageTemplate manually?

Create content type 'Portlet' that could have TAL as its content and when

You really should not call this a portlet. A portlet is very well defined by
JSR 168. Note that the Zope community -- specifically CMF and Plone -- have
misused the term for a long time.
class PortletView:
def renderText(self):
portlet = IPortlet(self.context)
format = portlet.format
if format in ('HTML', 'Plain'):
return portlet.getText()
elif format == 'Structured':
struct = structurize(portlet.getText())
doc = DocumentWithImages()(struct)
output = HTMLWithImages()(doc, level=1)
return output
elif format == 'Page Template':
page_template = PageTemplate()
page_template.write(portlet.getText())
output = page_template()
return output
But there is a problem. When I define a variable in template and call it
its ok. But I cannot call 'context' variable (for example div
tal:content=context/title/). This is my traceback.
Well, of course this does not work. The ``PageTemplate`` class does not know
magically about a context. Have a look at
zope.app.pagetemplate.viewpagetemplatefile.ViewPageTemplateFile to see what
is involved in making variables available.

Stephan
