hello, i suppose this is quite trivial, but it took me half an hour as i can't write elisp and didn't know what point-at-bol did :) i haven't tested it much, but it seems to work at first sight. hope someone finds it useful. -- erno

Multiple Data.fs files and one Zope install?
by Alexander Limi 24 Jan '00

24 Jan '00

Zopistas, Just a quickie: - Is it possible to have multiple Data.fs files in one Zope install? The scenario is virtual hosting, where we would like all the sites hosted on our box to have their own Data.fs file for backup and fallback. ...and if it's possible, then how do we do it? Regards, Alexander Limi PS: CC this to me, as I don't have the Zope list available right now. Thanks.

ZCatalog: underscore ("_") character is a separator
by Hung Jung Lu 24 Jan '00

24 Jan '00

Hi, Right now the underscore character is a separator in full-text index of ZCatalog. Does this seem reasonable? I have many variables that are named with underscores (like product_number, product_id, etc.) and ZCatalog cannot find the objects containing these texts. Wouldn't it be more appropriate NOT to treat the underscore as a separator? At this moment, which file do I have to modify to eliminate the underscore as a separator? (or equivalently, to make it a valid character.) thanks, Hung Jung ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

The new Byte Article by Jon Udell, http://www.byte.com/column/BYT20000121S0001, has an example of just this! The image is discovered and rendered by a process, with no "prior knowledge" of it's existence. Later, Jerry S.

ZClass "add" question
by James W. Howe 24 Jan '00

24 Jan '00

I've defined a new ZClass complete with customized form and add methods. The form displays some fields for the user to enter values into and the add method creates the ZClass and updates properties and adds content to the ZClass based on information entered by the user from the form. Depending on what is entered by the user, my add method may create new objects to store in the ZClass. My problem is that I can't seem to find a way to determine whether a user entered information. For example, my form defines fields where the user can specify the name of an image file along with some information about an image. If the user does not specify an image file, I don't want to add a new ZClass instance which would hold information about the image. In my add method, I've tried doing something like this: <dtml-if "REQUEST['photoFile']"> <... add the image ...> </dtml-if> That didn't work. Regardless of whether I entered information in photoFile the code inside the dtml-if got executed. I then tried: <dtml-if "REQUEST['photoFile'] and REQUEST['photoFile'] != ''' "> <... add the image ...> </dtml-if> This also failed. I added a <dtml-raise> tag to dump the contents of 'REQUEST['photoFile'] and it came out as ''. I don't understand why the code inside the dtml-if is executing. I'm sure that I'm doing something incredibly stupid, but I can't figure out what. Can anybody offer me any guidance? Thanks. James W.

Jon Udell documents the calendar tag
by Michel Pelletier 24 Jan '00

24 Jan '00

Jon Udell, in his lates byte article, has documented the Calendar Tag: http://www.byte.com/column/BYT20000121S0001 Of special interest is this quote: But despite the immaturity of Zope and its documentation, I've got to admit I've been bitten by the bug. I'm doing some really useful stuff with the product, and this week I decided it was time to give something back. If the major bottleneck is documentation, why not contribute some of my own? So here's a quick tutorial on Zope's Calendar Tag, which I hope will convey the flavor of Zope programming. Gee Jon, could you have come up with a better phrase than 'bitten by the bug'? ;) -Michel

Adding ZClasses within ZClasses (more questions)
by James W. Howe 24 Jan '00

24 Jan '00

I've managed to successfully create an instance of a ZClass within another ZClass programatically. However, I'm not sure why what I did worked. I have a ZClass which has ObjectManager behavior. When I create an instance of this ZClass, I also want to create a DTMLMethod and another ZClass as contents of my outer ZClass. To create the DTMLMethod, I'm able to do the following in my ZClass1_add method: <dtml-call "manage_addDTMLMethod(...)"> This creates a new DTMLMethod as an item contained by my ZClass1 instance. If I try to add my ZClass2 using a similar method: <dtml-call "ZClass2_add(...)"> it ends up being put at the same level as my ZClass1 instance. However, if I do the following: <dtml-with "manage_addProduct['my product']"> <dtml-call "ZClass2_add(...)"> </dtml-with> my ZClass2 is added as an item contained by ZClass1. This raises a couple of questions. First, why does the manage_addDTMLMethod(...) work without any extra effort? What is it about manage_addDTMLMethod which knows that the new method should be contained within my ZClass1 instance? Second, why does manage_addProduct['...'] work? My product already existed and I'm not really adding a new product, so why do I need to call manage_addProduct? Thanks. James W.

I'm not sure I understand, indexing requires duplicate data of some kind. And it's not one to one duplication, the catalog goes to great lengths to store that information efficiently. > As another example, consider a catalog of URLs (descriptor, > link, creation_date) gleaned from a URLClass ZClass.

URL information is generated dynamicly from Zope, there is no universal URL to object mapping, the information is distributed and implicit within the structure of the object system and how you access it. But I see what you mean, the thing is, you can't have an index really without a corpus of information *to* index, so there is allways duplication of information, otherwise you would have to do real time 'grepping' through the objects. -Michel

ZCatalog'ing nested ZClasses?
by Darran Edmundson 24 Jan '00

24 Jan '00

I have a nested ZClass (Foo2) in a folderish container class (Foo1), ie., Foo1Product Foo1Class Foo2Class My problem is that Foo2Class's meta-type does not appear in a ZCatalog instance's "Find items to ZCatalog" selection box. This is true even if the ZCatalog is created inside a Foo1Class instance. However, if I select "All types" in "Items to catalog", Foo2Class instances *are* found and catalogued. How can I get this nested ZClass to show up in the selection box? Cheers, Darran.
