Zope 2.1.7 has been withdrawn due to CVS confusion. Can you reproduce the problem on another version, such as 2.1.6?. Is there any indication of why it won't start (error message)? Did you start it with -D set, so it would display errors on the console?</loren> Yes, the script start script contains '-D "$@"' but nothing is displayed on the console when I try to fetch an object from zope.

sql-statements in DTML-Methods....
by Marc LUDWIG 20 Jun '00

20 Jun '00

Hi. This is one of the first times I'm working with Zope and databases. Until now - if I wanted to work with a databse, i always created a Z SQL method that I called from my DTML-method via <dtml-call "add_item(param1 = ..., param2 = ..., param3 = ..., ..."> (for example) or <dtml-in get_items> ... </dtml-in> (for example) In the Z SQL method 'add_item' or 'get_items', my SQL statement are defined. My question is now: Do I have to define one Z SQL Method for every SQL statement I want to perform on my database or is it possible to define SQL-statements and database requests in my DTML-method? Am I missing something? Any idea? Thanks a lot. Regards, Marc mailto:lutschi72@gmx.net

Simple addition seems a bit tricky in zope <dtml-call "REQUEST.set('CategoryTotal',0)"> <dtml-in "tmp.propertyItems()"> <dtml-let key="_['sequence-key']" value="_['sequence-item']" category="s[:1]" counter="_.getitem(category+'Total')"> <--// Here i want to concatenate the category from the value with the word total so that i can lookup my declared variable in the namespace. <dtml-var expr="counter=counter+value"> <--// Here i tried to increase the declared variable with the value. </dtml-let> </dtml-in> Can someone help?

Thanks Chris, > As for your error, it looks like something bad happened when zope tried > to write to the log file. Did you do any funny configuration fro your > logging? What version of Zope are you using? I haven't changed anything to my knowledge. It did stop working after a crash though. Perhaps something is corrupted, I got a friend to test my site. He kept rightclicking and choosing "back", as quickly as he could and then it crashed... I think the page it crashed on had some .js in it... erk, I am using "Notes on Zope 2.0" oh gee I thought I was using 1.6! What version would you recommend installing? Thanks, josh

Re: [Zope] 2.2.0 zclass weirdness
by Roman Milner 20 Jun '00

Well, I figure this out. HomeDir_factory was getting its Use Factory permission set to (disabled). I think this was becuase HomeDirContaine didn't automatically have "Add HomeDirs" in its list. Is this a bug? ^Roman >>>>> "RM" == Roman Milner <roman(a)speeder.org> writes: RM> I've created a ZClass call HomeDirContainer that inherits from RM> ObjectManager.

2.2.0 zclass weirdness
by Roman Milner 20 Jun '00

20 Jun '00

I've created a ZClass call HomeDirContainer that inherits from ObjectManager. In that ZClass I created another ZClass called HomeDir. The idea being that HomeDirs can only exist in HomeDirContainers. So, I add an instance of HomeDirContainer, then go into it and click "Add" - which is attempting to post to the current object and pass it :method=HomeDir_factory. And I get the following error: Zope Error Zope has encountered an error while publishing this resource. Resource not found Sorry, the requested Zope resource does not exist. Check the URL and try again. Troubleshooting Suggestions The URL may be incorrect. The parameters passed to this resource may be incorrect. A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the HTML source for this page.

Embedding authentication in a Zope Website
by knight 20 Jun '00

20 Jun '00

Greetings, Please bear with me, I'm still slightly new to Zope, but I'm pretty up on the structure, miscellaneous administration, etc. I'm also beginning to do well with Python development. I wanted to start adding authentication to my site via HTML forms, and I saw mysqlUserFolder. There aren't any real docs that come with it. More or less, a README that explains the feature set of the Product is all that it has. Installing mysqlUserFolder wasn't the problem. The problem is now dynamically outputting content based upon login information. How do I manipulate who is logged in? How do I check to see if a user is logged in, etc? Do I need to read some plain zope authentication docs? If so, please point me in the right direction. What do I embed in my DTML in order to check for authentication? I really appreciate the help... The Zope documentation is still a little out of order, and slightly confusing to navigate. Knight

ZPatterns, "Hello, world."
by Jeff K. Hoffman 20 Jun '00

20 Jun '00

Hello, I am trying to wrap my head around ZPatterns--I am hoping to use it in a project I am currently working on. Unfortunately, I'm not doing too well. :-) Is there a, "Hello ZPatterns World." example out there, anywhere, that shows the simplest usage of the framework? It would do me tremendous good to see a working example. Thanks, --Jeff --- Jeff K.
