Pls disregard the previous mail part about the new user. I had silly problems with the passwords which didn't match whatever I would do. I'm trying to figure out where it's coming from and if it's reproduceable I'll report a bug. Thanks hellekin

Problem with manage_addDTMLDocument(id,[title,file,REQUEST,submit])...
by Fr�d�ric Quin 14 Jun '00

14 Jun '00

Hi all, when I specify the file I want, Zope just copy the name of the specified file in the body of the DTML Document. It doesn't get the contents of the file... However, first I wanted to clone an existent DTML Document - situated in my Product - but Zope always clone it into the current Folder. I would like to clone it a subfolder of the current folder but it doesn't work. When I try that, with a dtml-with tag, I obtain the following error : Error Type: AttributeError Error Value: 'None' object has no attribute 'importFile' Here is the part of the code of my method "MenuClass_add" : <dtml-with "MenuClass.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.mps.manage_editProperties(REQUEST)"> <dtml-call "manage_clone(bm,'barre_menu_html',REQUEST)"> </dtml-with> MenuClass is my new ZClass herited from Folder bm is my DTML Document Thanks Frederic

Could not lock database file
by kwan 14 Jun '00

14 Jun '00

Hi, I am setting up pcgi with IIS. I got the following error: Zope Error zope has encountered an error while publishing this resuource exceptions.ImportError (,'Could not locak the database file. There must be \012another proccess that has opened the file.\012 ') I had this message before also, when I test with a test mechine. But that was my mistake that I forget to put the -p "D:\zope\zope.pcgi" when start the zope server. After I put this in, it work perfectly. However, this time, I did make this argument when start up the server. I am still can make it work. Can anyone give me idea? Kwan

ZClass newbie problem...
by Eric L. Walstad 14 Jun '00

14 Jun '00

I'm stuck. I would like to build a "shiny new ZClass" that has the following structure: WebSimProduct WebSim Class 'Properties' Property Sheet string RunID Calc Class Object 'Properties' Property Sheet PathToInputFile PathToWxFolder Results Class Object 'Properties' Property Sheet float gashtg float elchtg float elcclg float euihtg float euiclg I haven't seen anything in the Zope documentation on using Zclass instances as members of a super class. In other programming languages I would instantiate default objects when the WebSim class is initialized. That way, to use a WebSim object, all I would need to do is instantiate one, then fill the properties of the automatiacally-created Calc object and Results object. However, I'm not sure how to build these default objects in Zope. My next question is: do I have to build a bunch of products (one for the Calc class and one for the Results class, for example)? I can imagine this would result in a huge number of products under the control panel if this is the case. I would like to have just a WebSim product and have all the other classes defined within this product. Does Zope work this way? If not, how is this class structure (or one similar) achieved? BTW, I've read, and disected to the best of my ability, the Zope Developer's Guide and the Searchable Job Board HowTo and Tazzzz'sss Adding ZClass Instances Programmatically and the Zope Content Manager's Guide 'Turining an Application into a Product.' However none of these deals with classes that contain custom class objects. Thanks for the guidance (TFTG?)! Eric.

Does Zope support user authentication, sessions, etc?
by Boon Hoo 14 Jun '00

14 Jun '00

My upcoming project is to build an investment-related website that allows members to customise their profiles, portfolios and etc. Users can also gain access to "tools" that they have subscribed for. >From the specifications given, my first thought is to implement it in object-oriented way of programming. Zope (being open-source and OOP from ground-up) naturally came to mind. Therefore, i would like to know whether Zope is suitable (and stable enough) to develop this kind of websites, bearing in mind other criteria such as scalability, performance, and the "learning curve" involved. I have done programming in PHP before, and AFAIK to implement features such as user-authentication, sessions and permissions in PHP, we can either write our own libraries, or use PHPLIB. However, looking at PHPLIB, it seems to be quite buggy, and require a lot of work re-writing for some of its functions. Therefore, I would also like to know whether there's any authentication/session management modules(or classes) already written for Zope, and if they exist, is it easy to implement them(as in as easy as plug-and play, or a lot of coding required)? Thanks in advance. Regards, Thee Boon Hoo

It _looks_ like you have a "broken" object in your top-level Folder. "Broken" objects are created when Zope has a problem unpickling an object (usually because the add-on product that defines the class of the object is missing). Are you sure that you got all of your add-on products installed (and any other dependencies like external methods) copied to the beta install? Alternatively, it is possible that one of your add-on products is incompatible somehow with the beta (if it can't import correctly, for example, then objects created from the product would be broken). One way you could probably test this theory: o shut down your beta installation o cd to your lib/python directory and crank up a Python prompt o do 'import Zope'. Look for any tracebacks (though the product import process will likely consume exceptions when trying to import products). o for each 3rd party product in lib/python/Products, try to do: 'import Products.xxx' where xxx is the product package name. If a product cant be imported, you should get a traceback for it (please post it if you get one). Hope this helps!
