Which versions of Zope work with which versions of Jython (using Linux)? The only information that I was able to find was several years out of date.

a couple of basic questions
by Tudor Gabriel 20 Jun '07

20 Jun '07

Hi, thank you for taking the time to read this. 1. I'm trying to learn to write a website using zope, the progress is good but i need to understand how can i call an zope object (ZPT or SQL or Script) from a script in this setup: /root /mysite /db sql_do_something /script call_sql_do_something index_html i tryed to call it using sql_do_something = context['db/sql_do_something'] hoping that maybe using aquisition ... i can get the script ... but i get the message that he can't find the object. the only way i managed to call it is ... if the files are in the same dir. im currently using them this way ... but it's gonna get a mess soon, all those scripts and sql and ZPT in the same dir. 2. I'm not writing products, just simple ZPT and script ... and i want version control for them, i have svn installed but ... the files are all inside zope database (i don't even know how the database file is named). Is there a svn plugin or a way to add those files to repository? I think that adding the entire zope database is a bit awkward ... hard to diff etc. 3. Almost the same as the svn problem ... i want to backup my files from time to time .. db and code, i know how to backup my mysql db, but i don't know how to get the zope files. I think i i find the answer for the question nb 2, number 3 will be the same. Thank you, expert Zope programmers.

Auto Cataloging my ZCatalog
by kamal hamzat 19 Jun '07

19 Jun '07

Hello, I have a ZCatalog that my users use to catalog there news articles which are (DTML Documents). I have already explained it to them to always input the id for the new DTML Documents under "with ids" section on the Find Objects tab on the ZMI to catalog new articles. But most time they will not and they end up cataloging the entire articles which runs to 13,000 records. What i want is either to be able to display error when the "with ids" is missing on Find Objects form or to be able to automate it. For example use a python code. I am new to python but very eager to learn. Any help will be highly appreciated.

RSS to HTML in Zope
by Tom Von Lahndorff 18 Jun '07

18 Jun '07

Hi, Im still struggling to get an RSS feed converted to HTML in Zope using Universal Feed Parser http://www.feedparser.org/ + This feedpaser setup http://www.zope.org/Members/johntynan/feedparser I'm able to get an RSS feed converted to what looks like a dictionary and view it, however it shows up as a rendered string on the page. Whenever I try to get any of the keys, no matter how, I've tried every possible scenario, I get an error back every time. "Blah Blah" is not callable..., You care not allowed to access "blah Blah" in this context., Value 0, etc... I've also tried using the RSS Document in the XML Kit which ended up causing a runaway python method and took down Zope so I'd like to avoid using it. Half the time it gives back an error message anyway. If anyone has a relatively easy way to convert an RSS feed to HTML in Zope I would greatly appreciate any feedback on how to set this up. Thanks in advance.

Dictionary Key Error from Parsed RSS
by Tom Von Lahndorff 15 Jun '07

15 Jun '07

Hi everyone, I've used Universal Feed Parser to parse an RSS feed. Then used these instructions below to get the parsed data into Zope via an External Method. Everything seems to work fine except that I keep getting an error whenever I try to access a key from the returned data. The resulting data is returned as a dictionary and if I render it as is it works fine, however in both ZPT and DTML, when trying to access a key, for instance "feed" or "href" from the dictionary I'm prompted to login, which I'm unable to do with my admin login. After hitting cancel I get a Key Error that says You are not able to access 'href' (or whatever) in this context. Is there any way to somehow let Zope know that this data is 'ok'? Thanks in advance. "Pre-requisites ============== - Zope 2.5.x (developed and tested with Zope 2.5.1, but other minor versions should work as well) - feedparser.py 3.0 (http://diveintomark.org/projects/feed_parser/) developed and tested with 3.0 beta 22, the latest version Installation ============ 1. Installing feedparser.py --------------------------- 1.1. Unzip the archive (preserving path names) into /Zopesite/bin/lib/ 1.2. open a command prompt window and go to /Zopesite/bin/lib/ feedparser/ 1.3. enter the command (sans quotes): '..\..\python setup.py install' 1.4. after installation, enter the command: '..\..\python feedparsertest.py' 1.5. wait for testing to complete. On my laptop, 2051 tests ran in 118.481s 2. Installing the external method --------------------------------- 2.1 place the newsfeed.py module in the /Zopesite/Extensions/ directory 2.2 Add an external method to your zope site with an id and Module of 'newsfeed', and a function of 'parsefeed' 3. Installing the feed template ------------------------------- 3.1 Add a Page template to your Zope site with the contents of the nprnews.pt Page Template 3.2 examine the generic template rendering of NPR News, all fields from the feed should be available."

Packing the Data.fs with wget fails since 2.9.7
by Maurits van Rees 15 Jun '07

15 Jun '07

Hi, This blog entry shows how to use wget to pack the zope database, which you can then put in a cronjob to call each day or week: http://blogs.translucentcode.org/mick/2004/03/10/using_wget_to_pack_zope/ It is just one line: wget -q http://username:password@YOURSITE.com:8080/Control_Panel/Database/manage_pa… But as a comment on that blog shows: this does not work anymore. Zope now requires that you visit that form using POST, which is not what wget is doing automatically. So you get an error in your event.log like this: 2007-06-13T18:43:41 ERROR Zope.SiteErrorLog http://localhost:9080/Control_Panel/Database/manage_pack Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module <string>, line 3, in _facade Module AccessControl.requestmethod, line 52, in _curried Forbidden: Request must be POST I have tried adding POST data to the wget call. Then you get this and other variations: wget -q --post-data='days:float=1&submit=Pack' \ http://user:password@localhost:8080/Control_Panel/Database/manage_pack But that gives other errors: Unauthorized: Your user account does not have the required permission. Access to 'title_or_id' of (DatabaseChooser at /Control_Panel/Database) denied. Your user account, Anonymous User, exists at (unknown). Access requires one of the following roles: ['Manager']. Your roles in this context are ['Anonymous']. For zeo I could use the bin/zeopack.py from the zope software home, but not for non-zeo zope servers. Does anybody know a solution? -- Maurits van Rees | http://maurits.vanrees.org/ [NL] Work | http://zestsoftware.nl/ "Do not worry about your difficulties in computers, I can assure you mine are still greater."

a warning message before performing an action
by Alan 14 Jun '07

14 Jun '07

Dears, I have a web page with some buttons (<form action=...) to perform some action (by calling a python script). However, some actions (like 'delete' a picture for example) I would like to warn user before performing it. I recall from php how to pop up a window (or a drop down in Mac OSX) with a warning message prompting a 'Yes' or 'No' confirmation and I was wondering how would I do it with Zope, with an example if possible. Any help here would be very welcome. Cheers, Alan
