RE: [Zope] dtml-var question regarding images
by Meilicke, Scott 18 Oct '01

18 Oct '01

Welcome! Zope is different from other web servers, in that you are not dealing with files, using a '/' to move between directories, but rather objects (in the programming sense), so you have to use a '.' separator. However, while programming in zope uses objects, the HTTP side that your browser uses just sees a standard web server, hence the <img> tag that works with '/'. <dtml-var Images.ZAcmeLogo> The dtml-var manipulates the object. This gets converted to <img src="webserverroot/Images/ZAcmeLogo" width="X" height="Y"> (or something like that), and sent to your browser. -Scott -----Original Message----- From: Jerry Lake [mailto:jerryl@europa.com] Sent: Thursday, October 18, 2001 11:08 AM To: zope(a)zope.org Subject: [Zope] dtml-var question regarding images I'm just learning Zope, I apologize if this is a FAQ. I've created a folder "ZAcme" from the tutorial and in that I created an images folder for my personal organization, how can I call the logo image I put in the images folder via a dtml-var when the folder is below the root ? <dtml-var Images/ZAcmeLogo> does not seem to work whereas I can call it via an <img> tag <img src=Images/ZAcmeLogo> just fine. this is nothing major, but any thoughts on this are appreciated Regards, Jerry Lake Interface Engineering Technician _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

ZCatalog with OR expression
by Garikoitz Araolaza 18 Oct '01

18 Oct '01

Hi! I'm trying to get an OR expression from a catalog: For example: <dtml-in "Catalog(meta_type='Image', title='Z*')"> So, this way I'm having objects with meta_type='Image' AND title starting with Z. Now, I need an OR expression: I need cataloged objects with meta_type='Image' OR with title='Z*' This can be done adding "two Catalogs: <dtml-in "Catalog(meta_type='Image')+Catalog(title='Z*')"> But... this way I get some objects two times: the ones filling both expressions. How could this be done better? Thanks if somebody can help... Gari PS: The real case is more complicated, I'm searching dates between ranges... but I think that the problem is the basic solution... Thank you. _________________________________________________________ Aurki Euskara hutsezko bilatzailea http://www.aurki.com Zure laguntza behar dugu. Egin zaitez editore!

Zope DB or Postgres or what for 3.500 files
by Jan Ulrich Hasecke 18 Oct '01

18 Oct '01

Hi, I am discussing with a friend about solutions for his site. I am using Zope but cannot answer this two questions seriously. 1. Imaging more than 3.500 HTML-Pages with a text amount of two or three DIN A4 Pages per HTML-Page. Would you recommend to put them into a Postgres-DB or is it no problem for the Zope DB do serve and index this amount of files and text? Traffic is about 2GB per month. 2. I've been using the Loadsite-Script sometimes but I am not satisfied with the import of metadata. Is it possible to import metadata like "title", "description", "keywords", "author" and so one with a modified loadsite-script so that I can import his 3.500 files with normal HTML-Metadatatags into a folder and all is done?

conditionals inside dtml-let expressions
by Mitchell Model 18 Oct '01

18 Oct '01

Is there a straightforward way to bind one of two values to a let variable depending on the value of another variable? In C/C++/Java I would use the ?: operator, but Python doesn't have that. Or should I just bind the variable to None then set it later with something like <dtml-let var=None> <dtml-if "testvar==targetval"> <dtml-var expr="_.set(var, 'yes')> <dtml-else> <dtml-var expr="_.set(var, 'no')> </dtml-if> </dtml-let>

Regular Expressions, External methods and my great big headache
by Chris Muldrow 18 Oct '01

18 Oct '01

Howdy! We've been using a rather lengthy external method to parse out pieces of some files on our site. It's been working well, but we just upgraded from Zope 2.3 to 2.4.1, and now I'm getting a "maximum recursion error" when the script runs. I've narrowed it down to a couple of regular expressions--I take them out, and the thing works fine. I suspect there's an error with my logic in the building of these re compiles, but I'm not sure. (And they've never failed before. Anyone see the error of my ways? (Attached is the function that's failing. It's being fed news story-length chunks of text with html code inside. The first re is meant to pull out the contents of the body tag, the second is meant to grab the contents of any non- tag) Thanks! - Chris M. def getBody(raw): """ Generates the document source for the object by parsing out the body tag in the story and then stripping out all tags but the paragraph tags.

Still fighting ftp access to ZWiki pages
by Oliver Sturm 18 Oct '01

18 Oct '01

Hi again! I can't get a user who does not have the "Manager" role to be able to edit or even load ZWiki pages via ftp. I install a fresh Zope 2.4.1 with ZWiki 0.9.5. I create a ZWikiWeb. I can use the admin account to access ZWiki pages via ftp. I create a new user test (on the top level). I create a role test (on the top level). I assign the test role all permissions (on the top level). I am not able to access any of the ZWiki pages in the folder via ftp using the user test. I am able, though, to access all the DTML methods in the folder. This is (in a nutshell) the same issue I described in another post yesterday. Is it a bug? Is anybody accessing ZWiki pages without the Manager role via ftp? How do you do it? Should I post this somewhere else? Oliver -- Oliver Sturm / <sturm(a)oliver-sturm.de>

howto call Py_Method w arguments from DTML-Document
by hans 18 Oct '01

18 Oct '01

i have a Zope 2.1.6 (py 1.5.2) [yes, it stinks, tell my boss] this means i have no "bindings" in Zopes Python Method Interface. i try to call from DTML-Document(s) Python Method(s) (which call ZSQL-Methods). Both Python Methods and ZSQL-Methods have Parameters. Using <dtml-call "Top_upd(_.None, _, arg_TI=TOP_ID, arg_tls=toplangs, arg_tns=topnames) "> gives Error Type: TypeError Error Value: keyword parameter redefined ...traceback ...lib/python/Products/PythonMethod/PythonMethod.py, line 168, in __call__ (Object: Top_upd) (Info: ((None, <TemplateDict object at 871cfd8>), {'arg_tns': ['DTML', 'DTML'], 'arg_tls': [1, 2], 'arg_TI': '1'}, None)) i dont understand this error message, i changed every formal argument to avoid name clashes. i have tried calling also with - ( this, _, kw-args) same, but different traceback...lib/python/Products/PythonMethod/PythonMethod.py, line 168, in __call__ (Object: Top_upd) (Info: ((<Python Method object at 8611590>, <TemplateDict object at 8672a98>), {'arg_tns': ['DTML', 'DTML'], 'arg_tls': [1, 2], 'arg_TI': '1'}, None)) TypeError: (see above) [aside: why "this" in a DTML-Document leads to <Py Meth Obj> i have no idea] - ( kw-args) The last leads to Error Type: NameError Error Value: TOP_ID_NAME_upd # <-- zsql-method ...lib/python/Products/PythonMethod/PythonMethod.py, line 168, in __call__ (Object: Top_upd) (Info: ((), {'arg_tns': ['DTML', 'DTML'], 'arg_tls': [1, 2], 'arg_TI': '1'}, None)) File <string>, line 16, in Top_upd NameError: (see above) a) Is there a definite how-to/reference for calls of anything callable from anything able to call including parameter passing b) what have i made wrong and how to do it right?

Re: [Zope] ZOPE 2.4.1 and ODBC drivers report incorrect records
by Tom Deprez 18 Oct '01

It could be that there is a problem with the dtml displaying the results on the test page. This happens the same with the MySQL DA. Haven't found time to look at it, but I guess it won't be that big of a problem. I'm almost sure it is because of an error in the dtml, since it works (at least with MySQL) as it should when creating your own browsing method.

My problem is that the when searching for records and displaying them it reports incorrects values. The database is fairly small (only 2,000 records). When I test the number of records using the ODBC Connection TEST button it also INCORRECTLY displays the records. For example, it will display only 50 records and then when you choose to display the next 50 it produces an error message. I have compacted and repaired the database and reindex it.
