How to use newline_to_br?
by Roland C. Reumerman 04 Dec '00

04 Dec '00

Scenario: - a tried to show a multi-line text field in HTML with the current return line feeds converted to <BR> - I made a request form with a text field called data - in the response method there is a <dtml-var data fmt="newline_to_br"> On viewing the former, and then submitting it to the latter: Error Type: TypeError Error Value: not all arguments converted ?? I tried some alternatives, but nothing worked. _____________________________________________________________________________________ Get more from the Web.

FYI: Speakers for Zope Track at Python conference
by Paul Everitt 04 Dec '00

04 Dec '00

Howdy folks, it's that time of year again. The Python Conference: http://www.python9.org/ ...is Mar 5-8 in Long Beach, CA, and we're having a Zope Track again this year. Last year's conference proved to be a watershed event, with the attendance rising dramatically, the launching point for ActiveState getting into Python, and the first Zope Track. Plus all the snow. :^) This year will likely be an even greater increase. Now's the time for getting the speakers on the Zope Track lined up. (Actually, the time isn't now, the time passed a while back.) If you're interested in giving a presentation or a short talk on the Zope track, please send me an email *today*. It is a lot of fun and you'll be the toast of the town, and as long as you're not slated after Jim's "Acquisition Algebra" chat, everyone will love to hear what you have to say. :^) --Paul

Hi, To send attachments in Zope mail they should be inside zope right.I suppose we should store them as a file(available objects) in zope.In dtml-method by giving provision browse from the local machine can we first store them as a file & then send them as attachments ?. i am able to browse from the local mechine & store attachment to be sent as a file in zope but i don't know how to send the same attachment in mail automatically.Where actually the file(available objects) id's in zope will be stored ?. How can we mention about this id to take automatically in mail to be sent.The problem is each time when the mail is sent attachments will be different. please help me. bye, jacintha

It's NOT a Zope error

First, forget all what you know about web programming, languages, python and zope. Imagine you're just a good buddy who only wants to be convinced to allow you to use whatever tool you propose (yes evangelization...) Each time they see the message "Zope Error" (even for unauthorized login ! or your own programing error) they are telling "pfffffff this software is really buggy", and the poison is here. So i would suggest, as a "marketing" feature to change the error message to something more accurate or at least who doesn't imply Zope (something like "your code sucks" .. just kidding !). I know that i can patch zope (and i've done it) to change the general error message but this would be a general benefit for non technical people if they can leave this bad feeling about "Zope Error", because it's NOT a zope error, and finaly this simple thing makes more against Zope than a lot of real complain wich remains out of the knowledge area for managers or executives.

REQUEST.set('n', n+1) broken on zope.org
by Richard Jones 04 Dec '00

04 Dec '00

As the subject says, REQUEST.set('n', n+1) is broken on zope.org. The following DTML will raise an AttributeError on __add__: <dtml-call REQUEST.set('n', 1)> <dtml-call REQUEST.set('n', n+1)> Is this a permanent change and is this going into the Zope codebase?

Accessing hierarchical information in a CORBA server
by vonWedel＠lfpt.rwth-aachen.de 04 Dec '00

04 Dec '00

Hi folks, I looked into Zope quite recently and I'm very impressed of all its features. After getting started with some basics, I'd like to make a real-world application, migrating from a set of CGI-scripts written in Python but I'm still puzzled how to actually solve my problem, especially using the dtml-tree. I want to access information in a CORBA server which is more or less hierarchically structured, so I'd like to use the neat trees to display the hierarchy and selecting one of the items in the hierarchy directly should open a page with further information about that object. As I have to use CORBA, an external method written in Python seems the only possible way to make a connection from the tree to the server. In the How-To's, I found the following example (http://www.zope.org/Members/anthony/tree-coding-tricks) class _dummy: def __init__(self, name): self.name=name def child_lookup(parent): c = [] for i in range(0,5): c.append(_dummy("%s.%d"%(parent, i))) return c used like this: <dtml-let name="0"> <dtml-tree id=name branches_expr="child_lookup(parent=name)"> <b><dtml-var name></b> </dtml-tree> </dtml-let> This toy example is similar to what I would write, but I need to handle different object types on different levels of the hierarchy. The tree can obviously only handle functions, not real CORBA objects (as the note in the example section in the HowTo suggests...0, right? This means I have to cope with large if-then-else constructs in the function given to branches_expr? CORBA objects are identified by a so-called IOR which is some sort of a stringified object reference but in a non-readable way. Can I use a non-unique 'display name' for each node in the tree and some unique identfier (the IOR) internally? Sorry for so many questions, but I haven't found a lot of info about using the dtml-tree together with external methods. Lars

Re: [Zope] Help - cannot import zexp
by Dieter Maurer 04 Dec '00

Oleg Broytmann writes: > .... functions as default parameters to external method functions > cause import problems .... > .... > "Cannot import default_render from module __main__". Oops! What's that? > The default_render isn't in __main__, sure. I tried to create External > Method before importing, but this didn't help :( This is a severe danger of "pickle" and the external method implementation: * the implementation does not import the Python source files but reads them in and executes them. All functions and classes appear to be defined in the module "__main__". * The implementation places the function default arguments into the ZODB (as a pickle). * "unpickle" cannot load the corresponding object, as it imports "__main__" and looks there for the function -- in vain. As a rule: Avoid the use of class of function definitons from an external method source file for anything that may be written to the ZODB (or more generally be pickled; this applies e.g. to session context, too). This includes created object instances that may end up as attributes of Zope objects or function default parameters to external methods. If you defined such classes or functions in a true Python module, you should have no problem. What can you do, if your zexp is valuable? * put a dummy definition of "default_render" in the "__main__" module. You should then be able to import your zexp and change the problematic external method. I do not know precisely, what Zope's "__main__" module is. I expect the "z2.py". If this is not the case, then a small dummy product that does "import __main__; __main__.default_render= 0" should do the trick, whatever "__main__" may be. Dieter

again:authenticate and Zope 2.2.4
by Sven Hohage 04 Dec '00

04 Dec '00

I retry my question because it's important for my actual project. It seems to me that the authenticate- method is not working in Zope 2.2.4. Because of security-reasons?? 'Authenticate' can be used to compare the log-in-password with the one saved in the acl-users-folder. But if it's true how should I check if the user knows the Password?? Thanks

Re: [Zope] IMAP and WorldPilot?

* "Cymen Vig" <cvig(a)raw-io.com> | I'm trying to setup WorldPilot on one server with IMAP running on another. | The documentation for the install says simply: | | "Set your corresponding IMAP and SMTP servers, if they are not on | localhost." | | I went ahead and added a MailHost (SMTP) server but how do I add an IMAP | one? Do I need to digup a product? No, you just need to add the names of your usual IMAP and SMTP-servers to the config. The MailHost is not needed. -- Jørn Helge B.
