September 1999 - Zope

Newbie needs advice

HI, I have been playing with Zope for a few days, and I am trying to evaluate whether it could fit our needs. We are a group of people working in graphic design, both for printing and for the web. We are all located in different cities and have different specialties, but work on common projects. For each project, we must exchange numerous files containing some "metainformation" (for instance, project id, steps in the project, etc.). We are looking for a tool to help us manage and keep track of our projects and of the people involved in them. Most of these people are not computer-savvy, so that application should be easy to master by the end user. It should also have the following characteristics: - fast to implement; - very modular and incremental: some things should be implemented quickly, while more sophisticated tools could be implemented later. - highly cost effective (we are a small business). I have been considering using Zope for this project, or perhaps Zope + MySql. Please let me know if you have any advice or suggestions as to what would be good for this kind of undertaking. Feel free also to let me know if I have to be more specific in my queries. Oscar Picasso

Hi, With RH6.0, Zope2.0 I tried to pack ZODB3 and I obtain thje following message. Zope is started by root. Any idea ? System Unavailable This site is currently experiencing technical difficulties.

When I set up a virtualhost to point to a subdirectory of the Zope site, the manage screen goes berserk. It says things like "Folder at /ACLUG/ACLUG/ACLUG" when I ask for /manage on the virtualhost. The site is working OK (except for the darn base tag) but this isn't. Ideas?

Follow up on Zcatalog weirdness.
by Kuraiken 13 Sep '99

13 Sep '99

It seems it's not words less than 4 letters. I also have a CD titled "Hi Ka Ri" and searching for "hi", "ka" and "ri" respectively works as advertised. Which leads me to suspect that, for some reason, the words: for, you, me and to are "special". In that search refuses to find them. I'd sleep better if others could confirm this. (Perhaps the daemon under the hood is lazy or something... :-)) -- ----------------------------------------- Kuraiken - Python fanatic. ----------------------------------------- Python. Try it.

Using "Session" to store per-session data.
by Anthony Baxter 13 Sep '99

13 Sep '99

Rather than passing around lots and lots of data as hidden form fields all the time, I'm planning to extend Scott's Session object to support storing and retrieving of per-Session data. Issues with this: In a non-https environment, it would be rather easy to hijack a session by looking at a cache log. I could store the IP address, but this breaks many cache farms (where a session may come from different IP addresses... :( Is it better to store this in an SQL database, or in the session object itself? I want this to be preserved in the case where Zope restarts, which means I can't just use _v_object type variables. Storing it in the Session object itself means that the ZODB will grow at a stupid rate. Storing it in an SQL database means a bit of a performance hit. Has anyone already implemented something like this? Thoughts? Anthony

basic python -> dtml translation.
by chas 13 Sep '99

trivial no doubt, but buggered if i can find the python equivalent for "eval". eg. how would you rewrite this in dtml : for i in range(1,6) : print (eval('var%s' % i)) which prints out the values of var1, var2, var3, var4, var5, var6 <dtml-in "_.range(1,6)"> ?? </dtml-in> cheers, chas

Z-1.10.3, method invocation by URL: why doesn't this work?
by Thomas Riedl 13 Sep '99

13 Sep '99

Hi there, I just again hit the limited borders of my wanaabe zope zenism: (for reasons you wouldn't like to read the answer to your obvious question 'Why?' ;-) I'm still stuck to Zope-1.10.3) I thought of the following: Have a method 'framify' that inserts headers & footers 'round a document's body. Call it like /folder1/folder2/dtmldoc1/framify (just for aesthetics; args DO work, but I really like that URLism) and it displays dtmldoc1 in a nice, headered and footered version. But this wouldn't work, since I get this: <error> Bobo has encountered a problem publishing your object. Cannot locate object at: http://exit:9673/Zope/tomtest/nummer_2/framify Traceback (innermost last): File /mnt/universe/home/zope/Zope-1.10.3-src/lib/python/ZPublisher/Publish.py, line 877, in publish_module File /mnt/universe/home/zope/Zope-1.10.3-src/lib/python/ZPublisher/Publish.py, line 420, in publish (Info: /tomtest/nummer_2/framify) File /mnt/universe/home/zope/Zope-1.10.3-src/lib/python/ZPublisher/Publish.py, line 270, in debugError NotFound: (see above) </error> So, what is the difference to e.g. 'manage', which can be called that way? Would I need an external method? Does it have to be 'built in' into a class or Product to work that way?

ZCatalog uses UnTextIndexes. I believe confera uses TextIndexes. This list is obviously not going to work for lots of applications. What if you want to search for words like 'six' and 'five'? What if your indexing python code and want to find all ocourances of 'while' and 'for'? What if your indexing French or German? The reason why we have these as stop words is because, for most (English) 'documents' (meaning large bodies of text), these are the most common words encounterd, and have a higher chance of being in a document than not being in a document. The technical reasons get into the very precise and voodooish concepts of relevance, precision, and result set size. This is very deep stuff. Suffice to say, without stop words indexes grow huge, so clip this list at your own risk, and be aware that taking out 'Many' may improve your ability to index your employees, it may also drasticly reduce the relevance and precision while increasing the size of your result set for a different 'kind' of text corpus. > I just spent a few hours being tortured trying to find out > why a guy in > the Datbase of 10,000 whose name is 'Max Many', doesn't come up on a > last name search, and guess what, the Catalog doesn't index his last > name.

The current TextIndexing machinery was intended to be used from a document-centric standpoint. The need to text index small values was not considered way back when the first TextIndex was written. Given the amount of feedback we have recieved on this, it is obviously on our radar. -Michel

strange error with lines property
by Heiko Stoermer 13 Sep '99

I have a DMTL-Document with lines property. in an external method I gather lines of text from a file, concatenate them into a long string with '\n' as line separator and manage_changeProperties() this string into the lines property of my document. now: everything works well (e.g. displaying the lines in my document), but if I go to the documents property page in zope I get the following error: >Error Type: InError >Error Value: Strings are not allowed as input to the in tag.
