Help create filesystem skin with product
by yary 11 Oct '06

11 Oct '06

I'm having a problem which must have been solved many times before- trying to make a product that ships with a skin. I'm new to Zope development, been stumbling for a couple months with it. Ideally, the end user will unpack my product "Q" into a Products directory. They will be able to add a "Q" object to an existing CMF site, or create a "QSite" at their Zope2 root. If they create a QSite, my product should give it a QSkin during instantiation. I'm developing the QSkin (and the entire Q product) on the filesystem. Background: The product includes a subclass of CMFSite called a QSite. If the user creates a QSite, I'd like it to include a QSkin which the user can select from the portal_skins tool. The product is running on Zope 2.9.4, Five 1.4, CMF 2.0. It needs to work on Windows and Linux. (Would like to use Zope 2.10, Five 1.5 when someone compiles the win32 installer, so I don't have to worry about "five:traversable" directives! Already posted a request for that.) Customer requires that the product have no Plone dependencies. Product will require workflow, so it can have a CMF dependency. Could possibly implement on Zope 3, though I could not figure out basic workflow management on that platform, and would rather not re-implement something available on Zope2. Hurdles I've had so far in creating a skin: Using Five- seems to be the way to go. Started by trying "browser:page" & "browser:defaultView" with QSite/IQSite- really didn't know what I was doing, and a helpful sould pointed out, that is what skins are for. Tried using zcml "skin" directive, "broswer:layer", and "browser:defaultSkin". I can create a skin in zcml, and adding "/++skin++QSkin" to the end of any URL causes the page to load. However it does not look like a QSkin- apparently acquisition finds items in portal_skins before it finds resources added by five. So if I use zcml to add a Logo.gif, it won't override a Logo.gif already on the CMF site, to see it I have to also add "/++resource++Logo.gif" I cannot use defaultSkin with CMF, because CMF already declares a defaultSkin. Its better if the user picks the skin from the portal_skins management interface, but skins and layers declared in zcml don't show up there. As for "the old/tried-and-true way", can't use the ExampleFileSystemSkin or MinimalPloneSkin as a starting point, perhaps they use parts of Plone: "cannot import name ContentFactoryMetadata." http://plonebook.packtpub.com/chapter6_preview.htm looks promising. Hurdles I've had so far installing the skin: Tried using container events ("subscriber" zcml) to call a hook when a QSite is created, presuming that I'd work skin magic on the new site object from within the event handler. Alas that is not the intended purpose of "subscriber" and while it may work in the future, events don't fire on CMFSite objects yet. Am I supposed to create a "manage_afterAdd" method in my QSite object, even though it's depreciated? Hmm, just tried creating that as a method of QSite and it doesn't get called either- what's the right way? Thanks for reading my rambling.

Zope Crashes When Product Breaks
by natalie.l.doe＠gsk.com 11 Oct '06

11 Oct '06

I am new to using Zope. We are running a Win 2003 server with Zope 2.8.8 and have installed the IssueTracker Product. Everything was working fine and now I can't access the Zope manager at all. It seems whenever a product breaks, the manager breaks with it. I had this problem before when I tried to install the cookie crumbler. When I add an instance of this product I could no longer access any part of zope nor its other products. Now this may be a problem with the product itself but I'm having trouble troubleshooting the product problems if the whole zope interface crashes. Does anyone have any ideas on how I can get Zope running again? Things I've tried: restarting the Zope service from the Services app. I also checked the log to make sure it was running on port 8080. I currently get a page not found error when I go to this address. The last thing I did before this broke was add a couple issues to the issuetracker and added a user and that was the last I was able to access the Zope manager. Thanks ~Natalie

How can I store session data to db on login/logoff events ?
by Pletli Antal 11 Oct '06

11 Oct '06

Hi All! Sorry for my stupid question and my english: I would like store some session data to db when the users log into my zope system and when the session object will be deleted. When the users log into the system the index_html script sets some data to request.SESSION object. I have a script called "addScript" that runs when an object is added to transient data container. In the "addScript" I try receive data with yyy = container.SESSION.get('xxx') or item.get(....) but I cannot see the keys. How can I retrieve the user SESSION data when the items are created or deleted from the transient object container? Thank you in advance Antal

(this is > the first time I have used non-catalog aware instances, in previous projects > I used catalog-aware objects and just deleted the object in the folder and > the object was automatically removed from the zcatalog). I don't understand why the uid of 1049298593 works in retrieving the record from the zcatalog, but not when used to delete the record from the zcatalog?! (I have looked at the code in Catalog.py and nothing in the uncatalog_object method provides any hints as to why this problem is occuring). Any ideas would be really appreciated! Thanks, Jonathan

Production Advice
by Jonathan Cyr 11 Oct '06

11 Oct '06

Greetings All, After a long dev cycle, I'm putting a Zope web app into production shortly... and need some advice. What is a good daily backup strategy with Zope 2.71? I'll be running ZEO, and only use three add-on products, Formulator, VarImage and PIL. My application consists of regular items in the ZODB, two python Products, and a half-dozen ZClasses Right now, I'm developing on a WinXP machine, and am considering SuSE 9.1 for my spec, any experiences, good or bad?... YAST2-installed or manually? All advice would be helpful as I weigh my options, -Jon Cyr cyrj(a)cyr.info

Hi, We made some basic load testing against different Zope2 versions and found some unexpected results. Everything is summarized here : http://talk.lastminute.com/wiki/index.php/Loadtest We would appreciate any comment about it, and of course will answer any question you might have about our test. Thanks a lot.

doc string rules
by Dennis Allison 10 Oct '06

10 Oct '06

I just had LocalFS break under Zope 2.6.4 with Python 2.3.4 due to a "missing docstring". What are the current rules? Must everything (procedures, methods, classes, modules) have docstrings? Even when running with Z_DEBUG_MODE set to "yes".

However, some browsers (and servers) can handle them and some cannot. Often there is a configuration setting for this. Probably your browser is just omitting them, and that is why you are getting the default Zope page. Cheers, Tom P
