Datebug?
by Peter Arvidsson 24 Jul '00

24 Jul '00

I have encountered a strange and irritating problem. As I live in Sweden we use timezone 'GMT+1'. I have a form like this: <dtml-var standard_html_header> <form action="a"> <input type="text" size="15" name="date:date" value="<dtml-var ZopeTime fmt=%Y-%m-%d>"> <input type="submit"> </form> <dtml-var standard_html_footer> And when I press submit I come to this page: <dtml-var standard_html_header> <input type="text" value="<dtml-var date fmt=%Y-%m-%d>"> <dtml-var standard_html_footer> The input field are correctly displaying the date (in GMT+1) but when I submit the form and use the "fmt" the date is displayed with a decrease of 24 hours. Like if I write 2000-07-21 in the input-field the next page will display 2000-07-20. I I dont format the date on the second page the same date will be shown. It cant really be a timezone issue because it is decreasing the date by 24 hours and I only live 1 hour from GMT. The date on my computer and the server are correct. Does someone knows why this happens when I use "fmt" or is this a DateTime bug?

zcatalog and squishdot newbie question
by Sean Kelley 24 Jul '00

24 Jul '00

I have created a catalog and added my squishdot site to it. However, when I go to look at the catalog contents there are no squishdot articles listed (the suishdot site object is listed though). When I run a search for a keyword that I know is in the squishdot object, I get no matches (but do when I search for other non-squishdot keywords). I thought this may have something to do with running squishdot 3.1 so I upgraded to 4.1, reindexed and still nothing. What could be the problem? I heard somone say something about your catalog cataloging itself (mine does)- should it do this? I tried removing it but nothing. -- Sean Kelley

re: Meta Type Registry

I just tried adding a new ZClass in a new Product in my Zope 2.2 final installation. The multiple-selection widgit for choosing the base-classes has all the available meta-types prefixed with the name of their product, followed by a colon. For example, here's the list I get: AccessControl: User AccessControl: UserFolder OFS: DTMLDocument OFS: DTMLMethod OFS: Folder OFS: File OFS: Image ZCatalog: CatalogAware ZCatalog: ZCatalog ZPatterns: DataSkin ZPatterns: PlugInBase ZPatterns: PlugInContainer ZPatterns: Rack ZPatterns: Specialist ZClasses: ObjectManager So, it looks to me like the problem of meta-types clashing is taken care of, at least in principle. I note that the management screens' "add" drop-down list doesn't have the "product:" namespace qualification, and I guess that's where the problems lie. I doubt this would be much of a problem to patch, and it probably counts as a bug, if anyone is passing the Collector in the near future. Now, we might want to consider a product naming registry to address the problem of product names that clash... -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

An observation about manage_* methods
by albert boulanger 24 Jul '00

24 Jul '00

This has a question to it if I am not overlooking something. I often want to design dtml_methods that allow the end user to manage content under his control. An example of a typical manage method that you often see is like: >From TinyTable.py: def manage_editData(self, data, REQUEST=None): """Change item data""" self._rows = map(self._FixRow, ImportExport.ImportData(data)) self._n_rows = len(self._rows) self._GenerateIndex() return self.manage_editedDialog(REQUEST) Now there is an assumption in this code that the editing context that this is being called from is some manage_ method, hence returns like "return self.manage_editedDialog(REQUEST)". This is annoying if you are writing a user-managed content method that does not wants the user to see the manage interface because eventually it goes to one with such returns. Instead, I would like to have control on where he/she returns (often to the method I wrote or to index_html). I could do a <dtml-call "RESPONSE.redirect..., but the return self.manage_editedDialog(REQUEST) gets in the way. Am I overlooking something or is this a weakness in this design pattern for management? I could wind up making my own version of manage_editData that does not do the return self.manage_editedDialog(REQUEST). (I know some code at least conditionalizes this to the presence of REQUEST.) Thoughts? Ideas? Regards, Albert Boulanger aboulanger(a)ldeo.columbia.edu

request for advice
by Seb Bacon 24 Jul '00

24 Jul '00

Hello folks, I'm just beginning to design my first big Zope application. I'm writing to ask zopististitiatatas for some advice, since I'm a bit of a newbie and I want to make sure: [a] I reuse as much code as possible [b] I make my code as reusable as possible [c] my application is stable and scalable 1. Background to the application I'm building an extranet product in Zope. Much of it will be centered around a 'VersioningObject'. An example of such an object might be an image, a Word document. The objects will have a preview view associated with them. For word docs, this will be a html-ised version, for photos it will be a thumbnail. Perhaps in the future each object will also have rudimentary online editing facilities. The objects will all support versioning. This means each object can be superceded by another object of the same type. The version number will be incremented. Versions will also have Confera forums associated with them, and ACLs. Now as I see it, I want a VersioningObject to be a Folderish object that can contain a set of Versions, which are just a load of File objects of the same type. The folder has a method which slects its most recent child file object and displays it by calling its preview method. Older versions are read-only and are listed by title only. 2) My questions: i) I'm worried about the sheer volume of binary data that would accrue in the VersioningObject: a single VersioningObject might be a Word doc of 25Mb. If it has 10 versions and there are 10 such objects, that's 2.5Gb in the ZOBD. I presume this would be a bad idea performance-wise; any suggestions? ii) I'm interested in using ZPatterns because I reckon they sound like they might enhance the reusability etc. of the code; I know there have been some pointers recently, but which ZPatterns could I benefit from? or are they too arcance to worry about for now? iii) Is there any other miscellaneous advice? e.g. has anything like this been done already? Thanking you all, ladies and gentlemen. Seb.

more catalog issues
by ed colmar 24 Jul '00

24 Jul '00

Strange... Now my 2.2 catalog is giving me the problems were supposed to be bugs in zope (catalog) 2.1.5 and lower... Inconsistancy, and missing indexes...??? When I update the catalog it corrects itself. hmmmm Any clues as to why my objects get cataloged incorrectly to start with? Is there a better syntax to use than 'catalog_object()'? Thanks for any pointers! -e-

Catalog contains items, but no results
by ed colmar 24 Jul '00

24 Jul '00

Hmmm, more catalog strangeness.. I've finally gotten my product to add objects to a catalog correctly (with the correct URL) Whee! On my 2.2 development machine all appears fine, but on the 2.1.6 production server all searches come back with no results. When I look in "cataloged objects" in the management interface, there are many objects with correct URLs...??? Obviously I could just upgrade the production server, but I'm curious if there's something inherently wrong with my code. This is a sample of a call that I make to the Catalog. base_url=self.site_url() self.Catalog.catalog_object(ob,base_url+'/Promoters/'+id) Thanks for any ideas. -e-

Zope and Mac
by Tom Scheidt 24 Jul '00

24 Jul '00

Hi, I'm having problems installing products from a Macintosh. I downloaded them onto my hard drive and uncompressed the .tgz files with Stuffit Expander. I then FTPed them with Fetch to my server, then restarted Zope. The products were listed in the Product Management folder, but they had broken icons and were not showing up in the "Add" list. I did not have this problem when doing the exact same thing on a PC. Any ideas how to fix this? Thanks.
