Newbie dereferencing problem
by Kirk Strauser 16 Oct '01

16 Oct '01

I apologize for the (probably FAQ) newbie problem. FedEx hasn't delivered my copy of "The Zope Book" or "Programming Python" yet, so please forgive me. Suppose I have the name of an object in variable `foo'. I would like to test for the existence of the named object. Suppose that foo=='bar'. The following won't work: <dtml-if foo> <br>Yep! </dtml-if> because `foo' will always have a value. How, then, can I see if `bar' exists? A million thanks, -- Kirk Strauser

problem.
by Tom Deprez 16 Oct '01

Hi, I'm propably overlooking something, but I'm facing here a problem which I can't solve right now. Perhaps somebody knows the solution. I'm creating a zip file and then return that one to the browser so that the user can download it. The problem is that the created file turns out to be corrupt ie the data is altered. You can see this below, where I show you the file which I zip and then the file after unzipping the downloaded file. Does somebody has an idea? I've also problems with PDF files and I'm starting to believe that this is the same problem. I'm running zope 2.4.1 on a windows nt machine Thanks in advance. Before Zip: *** Installation Started 04/05/00 21:48 *** Title: Zope Installation Source: C:\Zope\program\Zope-2.1.6-win32-x86.exe Installation Aborted! User Rights: Admin *** Installation Started 07/17/00 11:01 *** Title: Zope Installation Source: E:\Internet\download\Zope-2_2_0-win32-x86.exe Installation Aborted! User Rights: Admin After Zip: *** Installation Started 04/05/00 21:48 *** Title: Zope Installation Source: C:\Zope\program\Zope-2.1.6-win32-x86.exe Installation Aborted! User Rights: Admin *** Installation Started 07/17/00 11:01 *** Title: Zope Installation Source: E:\Internet\download\Zope-2_2_0-win32-x86.exe Installation Aborted! User Rights: Admin Ø3ÉsQ Q If I look in a textfile the above returns etc were also transformed. Used code: import zipfile import tempfile def zipfolder(self): filename=tempfile.mktemp()+'.zip' zip=zipfile.ZipFile(filename,'w',zipfile.ZIP_STORED) zip.write('c:\install.log') zip.close() return open(filename).read() and method calling above code: <dtml-call "REQUEST.set('Content-type','application/zip;')"> <dtml-return expr="testzip()">

Try renaming the file extension to be .tgz. When I downloaded the product, it was saved as .tar, which caused WinZip to fail with the same error message you reported. It worked for me. Good luck, Simon. -----Original Message----- From: Hamzat kamal [mailto:hamzatk@dnetsystems.net] Sent: 16 October 2001 14:58 To: zope(a)zope.org Subject: [Zope] LoginManager Problem Hello to U all, I find it difficult to open the LoginManager 0.8.8b1.tgz for installation.

RE: [ZOPE] newbie question: getting title_or_id from calling document
by Simon Brogden 16 Oct '01

16 Oct '01

I don't think I've expressed the problem clearly enough. It's not the folder title we need, it's the title/ID of the document/method that includes the header(via "dtml-var standard_header") . The site has pages with a lot of common content that can be split into the standard_header or standard_footer objects. The header has an HTML block: .... <head> <title><dtml-var title_or_id></title> </head> .... When the header is used by a page, I want the title to be that of the page that includes it, not the name of the header file. So, if index_html, with a title of "Homepage" has: <dtml-var standard_header> I want the resultant HTML to look like: .... <head> <title>Homepage</title> </head> .... Not "header" or the title of the standard_header file. I'm guessing that the same is going to apply to the footer, as it needs to display the modification time. I want to make the maintenance of the site easier by lumping together the common parts. If I can't get the above to work, I'm assuming that the only resort is to be long-winded (like my email) and forget about using headers & footers and hardcode these bits into every page. There's a lot of JavaScript too, which needs substitution for each page it's used on. So it's not just the HTML title block. Am I missing a technique/being thick? Tanks for your time, Simon. -----Original Message----- From: Trevor Toenjes [mailto:zope@toenjes.com] Sent: 15 October 2001 19:25 To: Simon Brogden; zope(a)zope.org Subject: RE: [ZOPE] newbie question: getting title_or_id from calling document >I then created another header > (public_header) and test (testing) DTML methods, and get the same > results when I try to display the title/ID of the calling document in > the public_header DTML method. If you want the title of the folder, then your calling-Document needs to be a method. If there is no reason that your DTML-Doc has to be a doc, this is your solution. DTML-docs are folderish and have their own properties that will be inherited by a method in the namepsace, overriding the folder properties. This is why I have been told dont use DTML-Docs. I am sure there is some DTML-magic workaround for your public_header that only calls the title of the objecttype('Folder'). But sometimes Zope work-arounds are a replacement for mis-used object types and architecture. -Trevor > -----Original Message----- > From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of Simon > Brogden > Sent: Monday, October 15, 2001 1:47 PM > To: zope(a)zope.org > Subject: RE: [ZOPE] newbie question: getting title_or_id from calling > document > > > Thanks for the swift reply Trevor, very much appreciated. > > I think I understand what you mean, but I'm unsure as to the solution. > > I've recreated the header and the index_html as DTML methods, both in > the same folder, and know get the folder name as the title, as expected > based on what you said in your email.

Excluding specific objects from ZCatalog indexing
by Harry Wilkinson 16 Oct '01

16 Oct '01

Hey all :) What's the simplest way of excluding specific documents from a search? Well, not just from a search; it would be nice if they were never indexed in the first place. I've heard rumours that it's very easy to do and the mechanisms for excluding them explicitly are already there, but I haven't yet found out if these rumours are true :) If possible I would like to avoid having to do things like add another index to the catalog specifying whether the document should be visible. Thanks in advance :) Harry

Hi all, I want to use formulator + z sql method to insert data to a Mysql db. Got the form setup, but I have some fieldS that are "textarea" field type in the form, blob in my DB. The problem is that in the sql insert command, the following: "<dtml-sqlvar instructions_recette type="blob">" is not recognized by the Z sql method. Also, what are the valid data type for zsql method? The only one I could find where string or int.

Static content issues
by Gary Algier 16 Oct '01

16 Oct '01

I have had zope running here for a few days now to investigate using it as a place for the whole company to be able to put documents that they want to share with the rest. This will be a lot of files with very few changes each day and I realize now that everything is stored in all one file -- var/data.fs. So, the questions become: 1) How will this impact my backups? As I see it, eventually this file will become huge and I will be saving it to the backup tape every day. How can I only save the changes? Is there a way to get it to keep objects of type "File" external? 2) What do I do to restore only part of it? Often I get people that say they need something restored from several days ago because thay made a mistake. How can I handle this with everything in one file? 3) Should I be using a different product, like Apache + mod_dav and leave zope for more dynamic content? Apache does not have the integrated access management. People would need to edit the .htaccess files manually. -- Gary Algier, WB2FWZ gary.algier(a)ulticom.com +1 856 787 2758 Ulticom Inc., 1020 Briggs Rd, Mt.
