problem/missunderstanding?? with refresh
by Robert Rottermann 13 Nov '01

13 Nov '01

I created a product that adds new rules to structured text. To this aim I base a class on Structured Text and add to the rules of the base class like so: class DWIClass( StructuredText.DocumentWithImages.__class__ ): text_types = StructuredText.DocumentWithImages.text_types text_types.insert(1,'doc_named_linkEx' ) text_types.insert(1,'doc_inner_linkEx' ) text_types.insert(1,'doc_redPicture' ) My reasoning is that as text_types is a class variable it exists only once. However when I refresh the product after a change the above lines are added each time anew. Now my questions: Is my code wrong from a python view of things, or should refresh clear the whole thing? Does Python create an instance of the base class and an instance of my class?? Robert

Zope Error Logging
by Arun Joseph 13 Nov '01

13 Nov '01

Hi, We have developed a product (a mini ECRM) on Zope/Python/Mysql and the product is currently used by a few customers. Off late on our production server, we are getting zope error messages on the linux console. We believe that this is affecting the performance. I have turned on detailed error logging, when zope is started using the -M switch. When I read the resultant error log file, I find a lot of information, some of which is not quite clear. Can anyone please tell me, what the data in the error log file means? A sample of the text from the error log file is given below. B 160787448 2017-11-13T06:29:43 GET /AukumProject/Admin/ListLicense.dtml/manage_ main I 160787448 2017-11-13T06:29:43 0 A 155066912 2017-11-13T06:29:43 302 486 E 155066912 2017-11-13T06:29:43 Thanks in advance, Cliff __________________________________________________ Do You Yahoo!?

Cannot Import DateTime

12 Nov '01

Hi; I'm trying to install EMarket and I've run into this problem: >2001-11-12T19:11:58 ERROR(200) Zope Could not import Products.EMarket >Traceback (innermost last): > File > /apache/ZopeInstallation/Zope_software_home/lib/python/OFS/Application.py, > line 558, in import_product > File > /apache/ZopeInstallation/Zope_software_home/lib/python/Products/EMarket/__init__.py, > line 12, in ? > File > /apache/ZopeInstallation/Zope_software_home/lib/python/Products/EMarket/EMarket.py, > line 23, in ? >ImportError: cannot import name DateTime Now, that line in the complaining script reads thus: from Globals import HTMLFile, MessageDialog, Persistent, DateTime So, apparently, it's importing all the other modules from Globals, why not DateTime? Or, how do I install DateTime? Or check if I have it? TIA, BenO

ZSQL caching question
by Schmidt, Allen J. 12 Nov '01

12 Nov '01

We have a section of our site delivering online classifieds which are imported from text file into a Microsoft Access2000 DB and retrieved using ZSQL methods connecting to Access with a ZODBC adapter. Works fine. Most of the expensive ZSQL methods are cached in the Advanced tab. To make the switch to MySQL, I copied the whole Classifieds folder and renamed it. Then created a MySQL connection to the new database and went into each ZSQL method and pointed them to the new MySQL DA. I checked the caches and they are still there. Problem: Even for one user while testing, the site section is VERY SLOW. Our admin says while monitoring the MySQL DB the connections go way up and it loads up the server. Question: Are the caches 'moving' along with the ZSQL methods when the DB connection was changed? Grasping at straws but it should be faster than using Access. The other site we converted to MySQL from Access did not have the problem and never thought to check the caches...it just worked and was much faster. Any ideas or am I just missing something?

There is a whole slew of methods for manipulating Zope objects, check the Zope API section in the Zope Book. Depending on what you are actually trying to do there might be a more Zope-like way of accomplishing it than with the External Method hammer, but without knowing what you are trying to do it is hard to guess what that more Zope-like thing should be.

by csnorville＠fedex.com 12 Nov '01

12 Nov '01

Hi Everyone, I am fairly new to Zope and I need some assitance on something that I know is fundamental so please don't beat up on me too bad ;-) I am try to open a file with a Python Script in Zope for content manipulation. This is a text file, I basically want to read a number, operate on it and write it back out. However when I try to get my file handle I get; file=open("/home/chris/misernumber", "r+") Zope Error Zope has encountered an error while publishing this resource. Error Type: NameError Error Value: global name 'open' is not defined I tried creating the file as a Zope object but I get the same error. Again I know this is fundamental. If ya'll can help me with this, or at least point me to some documentation it would be deeply appreciated. Thanks, Chris

Best way to do "links"
by Oliver Bleutgen 12 Nov '01

12 Nov '01

Hi, I am unsure how to achieve the following in a product: I have a folder with templates which shall be used to render articles. This folder will be the central repository of templates for all articles which find it in their acquisition path. Now, I want be able to dynamically assign (and change) templates for a given article, and if I edit one template it should reflect in all articles which are configured to use that template. In http://lists.zope.org/pipermail/zope-dev/2001-May/011187.html Shane Hathaway describe hardlinks, which seem to do what I need. i.e. I then just do t = template_folder.one_template self.template = t I looked at how ZSQL-methods solve that problem (usage of SQLConnections), and as far as I can see ZSQL-methods just store the id of the ZSQL connection and use that everytime they need to access the DB. Is that right and if so, why is it done that way? Doesn't give that a performance hit? And the last one: Will the above described method still allow import/export these instances? cheers, oliver
