Can anybody please provide a simple example of a working usersource written in python? I've written this, but it just does not work, all that happens is that it writes opened to /tmp/source.log class USER: "Just a little test" name = None roles = [ 'Anonymous' , 'member' ] domains = [] def __init__(self, name): self.name = name class SolidUserSource(BasicUserSource): """ Solid User Source """ __plugin_kind__ = "User Source" meta_type = "Solid User Source" f = open("/tmp/source.log",'a',0) f.write("opened\n") #def __init__(id,title): # self.f.write("init %s %s\n" % (id,title)) # self.id = id # self.title = title def existsUser(self, name): self.f.write('Users exists %s\n' % name) return 1 def retreiveItem(self, name): self.f.write('Creating object for %s\n' % name) return USER(name) def rolesForUser(self, user): self.f.write('Returning roles for %s\n' % user.name) return user.roles def domainsForUser(self, user): self.f.write('Returning domains for %s\n' % user.name) return user.domains def authenticateUser(self, user, password, request): self.f.write('Authenticates user %s\n' % user.name) if user.name == 'aaa' and password == 'aaa': return 1 == 1 return 1 == 0 -- - Terje tm(a)funcom.com

Zope Content Management System
by Troy Coburn 25 Aug '00

25 Aug '00

Hi there, I am working on a project and have been looking at the Zope Content Management System as part of the solution. However, I have a couple of questions. From what I have seen so far, the page generation is all done through the Zope Management Interface, and the content of the page is done through a textarea requiring the user to have knowledge of the zope system(DTML) and HTML. With type type of solution I am looking for however, I need page content to be generated be users that have little or no knowledge of HTML. What I am wondering is if it is possible to integrate the Zope content management system with Cold Fusion as I can allow users with no knowledge of HTML to use an interface designed with Cold Fusion to create page content. I do not wish to build a content management system from scratch with Cold Fusion. Any suggestions and/or comments would be very helpful.

ZPatterns bug: Specialist does not implement _PropertySheetsFor(client)
by Steve Alexander 24 Aug '00

24 Aug '00

I'm using ZPatterns 0.4.1snap1. The LinkToParentProviders datamanager doesn't work properly because it assumes that the Specialist it lives in has a _PropertySheetsFor(client) method. However, Specialists (and DataManagers) don't provide this method. This stops /specialist/object/propertysheets/manage from working. It also stops _v_currentSheets from returning all the sheets a Dataskin might have. Phillip, is this fixed in your internal version? If not, I'll add the method over the weekend. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Re: ZPatterns.. Property sheets... once and for all. ;-)
by Steve Alexander 24 Aug '00

24 Aug '00

Steve, I've applied my alteration to manage_tabs.dtml, and I have successfully created two propertysheets, "foo" and "bar", both with the string property "bart", and with different default values. All this, using the management interface on /specialist/object/propertysheets/foo/manage and the equivalent for bar. This is with the *very latest* CVS Zope 2 and ZPatterns 0-4-1snap1. I was using a Dataskin-derived ZClass instance. Perhaps that makes a difference? It really shouldn't matter though. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

This method added to DataManagers.py seems to fix it. def _PropertySheetsFor(self, client): """Return a (possibly empty) list of PropertySheet objects for client""" # Note: this could include duplicate sheets if persistent sheets # are defined by more than one provider! sheets = () for ob in self._uniqueProviders(('sheets',)): sheets=sheets+ob._PropertySheetsFor(client) return sheets I'm not sure about the semantics of this though. With this method added, when a specialist is asked _PropertySheetsFor, it looks in its own plugins only. It does not look in any of its Racks. I guess it'll do for now. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

WHat your question is, probably, is whether you can you wysiwyg HTML editors with Zope. Some minor inconveniences aside that mostly have to do with file extensions, the answer is yes. As Zope speaks ftp and WebDAV and a host of other protocols, you can easily prepare Zope content with tools like HomeSite and Dreamweaver (and many other tools). Just try it out on a Zope installation hth Rik

This seems to be a pcgi (Zope) error though. Only used it on NT4 and IIS4 but from the above a basic incompatibility seems unlikely (to me). Rik
