Using Cookie Data
by Jim 24 May '00

24 May '00

I have a cookie that contains the value of an psql key as its value. I want to retrieve the value and use it to call the psql query method to retrieve the data. The code that I am currently using is <dtml-in qryGetCustomer(REQUEST.cookies[Company_Name)]> The company record has been retrieved for <dtml-var company_name>.<br> </dtml-in> where Company_Name is a property containing the company name and is the name of the cookie, and company_name is the first field that should be retrieved from the psql database query. When I run the code I get Error Type: KeyError Error Value: qryGetCustomer(REQUEST.cookies[Company_Name)] Any help out there on helping a Zope newbie to get the data from his psql database with a value retrieved from a cookie? -- Jim Zope is cool!

still trying to get Catalog to work in my python product
by ed colmar 24 May '00

24 May '00

Thanks to everone who has given me suggestions on this. I really do appreciate it. After looking over the PTK snapshot, I've tried to duplicate the catlog that is implemented there. I could not find any search utilities built in, so I'm assuming this is still done by adding the ZsearchInterface from the management screen. Is this right, or is there some built-in PTK searching tool? So now I have a "myproductcatalog" class which inherits ZCatalog. All it does is set up the Indexes, and columns In my base class, I initialize the catalog using (PTK code): # Install MyCatalog id = 'SiteIndex' catalog = MyCatalog(id, '') self._setObject(id, catalog) catalog = self.SiteIndex catalog.initialize() My sub-classes are all catalog aware, with reindex-object in all of the editing areas. I don't see my catalog when I go to add a Zsearch interface. Am I supposed to? What else do I need to do to make this work? -ed-

RE: [Zope] Netscape Image Problems (LoginManager?)
by john＠nurl.net 24 May '00

Well I have determined that it has nothing to do with PTK or Login Manager, well I think anyway....... If you hit reload it breaks the images on the root level, if you put your cursor in the Location, or URL field and hit enter it reloads fine. I truly don't understand this problem and it only does it with images, in Netscape, is this an issue that everyone is just accepting or is there a fix for it. j At 08:51 AM 5/22/00 -0500, you wrote: > >I'm not using PTK, but I am using LoginManager.

Subclassing from Custom Python Classes
by Pete Kazmier 24 May '00

24 May '00

I need some guidance or pointers to more information. My Zope journey began last Thursday and I've been glued to zope.org ever since. I'm trying to understand the following paragraph from the Zope Developer's Guide from the section on "Subclassing from Custom Python Classes": >> You should also note that your subclass must obey the ZODB >> persistence rules, which basically state that mutable sub-objects >> should be treated immutably. For example, >> >> self.bird='parrot' # OK >> self.map['bird']='parrot' # NOT OK, will not trigger persistence >> machinery >> m=self.map >> m['bird']='parrot' >> self.map=m # OK, treats a mutable object immutably What are these "persistence rules" and how come the second example is ok? I thought in Python, when you assign "m = self.map" that m is simply pointing to the same object as self.map and that any changes to m affect self.map too? Does the "self.map = m" have any effect? Don't they point to the same object? I ask because I've already built my first product based on a custom python class I wrote (its a router object that has methods to query various snmp oids) based on a ZClass and I want to make sure that I am not doing anything wrong. In addition to the methods that query the oids, I store the results in an instance variable of my Python class so I can cache the information for a specified amount of time. Is this safe to do? Can I store these values in my Python instance (self.xxxx), not a ZClass property? Also, What happens if multiple people activate my query method, do I need to worry about them stomping over each other as the method writes the results to the instance variables? Is there any record locking of objects? Lastly, since I couldn't really find any pointers regarding a builtin Zope scheduler that is bug free, I need to write a small python script that I can place in a cron job to run every ten minutes to call the query methods of these objects so they update their cache instances. Is there a link on how to get a regular Python script access to the ZODB? Thanks in advance!! Zope is great!!
