Re: [Zope] What if you can use Zope on development server only?

I do have CGI and telnet ability with this host, but I'm surprised that's sufficient to run Zope with. I thought Zope would require a tighter integration with the web server (e.g., a mod_zope or something that needs to be compiled in so that Zope can catch special Zope-intended requests), and that I'd need root to install it. Do I have a misunderstanding of how Zope relates to the web server? Is simple CGI access really enough to install and run Zope? I was basing my understanding on the architecture documentation at http://www.zope.org/ZopeArchitecture and http://classic.zope.org:8080/Information/Components. > One note though: many ISPs don't want you to run a long-lived process. >If that's their policy, then you'll run into trouble that way.

I was even thinking I'd have to possibly write my own mirroring script, but wanted to see if there was a better way first. Do you remember anything else about that product which might help me do a web search for it better (e.g., it definitely used the word "mirror", used the word synchronize a lot, etc.). thanks, Anthony ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Property Sheet access from Python Products
by Robert Roy 19 Mar '00

19 Mar '00

I am creating a product in Python and I want to use property sheets. I am able to add sheets and add properties to those sheets. However how I have to access the property sheets differently than if I was accessing property sheets on a ZClass programmatically. I suspect that I am perhaps not using the right mixin classes. For instance, I have a property sheet 'Private' with an attribute 'prop1' If I create this in a ZClass, I can use <dtml-var prop1> to access my attribute. in my class I have to do the following <dtml-var "propertysheets.get('Private').getProperty('prop1')"> likewise in Python code I must access the attribute using self.propertysheets.get('Private').getProperty('prop1') where in a ZClass I could do propertysheets.Private.prop1 My class declaration is as follows mixins: class base(ObjectManager,PropertyManager, Acquisition.Implicit, Persistence.Persistent, RoleManager): Am I missing a mixin somewhere? Or do I have to access the attributes differently from a Python Class? Thanks Bob

Public available DTML Source of zope.org?????
by Oliver Andrich 19 Mar '00

19 Mar '00

Hi, may be some people might remeber my question concerning the user folder question. Well, I haven't got any answer yet. But I found a source a knowledge that would give me all the information. Basically I don't need much more then the register DTML method of zope.org. Is the DTML source for the user registration and user updates available for download somewhere? When I hit the view "DTML Source" link I get a "Not Found" error. Everything else on Zope.org can be inspected this way, but why not these pages? This can't be such a security problem at all. Or am I just to dumb to discover the trick. Thanks for any hint. Best regards, Oliver Andrich

Find object in a directory question
by Chris Niekel 19 Mar '00

19 Mar '00

Hi, I've created a ZClass 'CLink', which contains a URL, title and such things. In my dtml-pages, I can do <dtml-var slashdot>, and the slashdot-clink object will insert the <a href=...></a> stuff for me. I've got this working using the Renderable class. I've planned to put all CLink objects in the /links folder so I can automatically create 'bookmarks' out of the links I reference to. I also want to be able to categorize the links into subfolders, so I want to have a links.sports.ski.resorts directory with ski resorts, and a links.news.nerdish folder for nerd-related news. I can use <dtml-var links.news.nerdish.slashdot> to refer to the slashdot object that way. However, I want to easily change my categories, without changing all <dtml-var ...> that reference object in the categories. So I figured, I'd make it <dtml-var links.find('slashdot')>. This should one day be the same as <dtml-var links.news.slashdot> and the next day the same as <dtml-var links.news.nerdish.slashdot>. With my external method (which only looks in the current folder so far), I can't get this to work. Any ideas? Would the same be easier or simpler using a ZCatalog? Refering to a link should not be too much typing. As an extra question: is it possible to refer to an object in multiple places, like softlinks (or hardlinks) in unix? Suppose I have a folder with 'My Frequent internet-visits', and 'News', they could both contain the same CLink. Is that possible in zope? Well, hope I made anysense.. Thanks, Chris Niekel

problems compiling ZMySQLDA
by Daniel Weber 19 Mar '00

19 Mar '00

This is product downloaded form zope.org. Details: Python 1.5.2 MySQL 3.22.32.1 Redhat 6.1 system. All development libraries/includes installed (I think). I run the make -f Makefile.pre.in boot, then make and get the following errors: gcc -fPIC -I/usr/include/mysql -g -O2 -I/usr/include/python1.5 -I/usr/include/python1.5 -DHAVE_CONFIG_H -c ./MySQLmodule.c ./MySQLmodule.c: In function `pythonify_row': ./MySQLmodule.c:238: warning: assignment from incompatible pointer type ./MySQLmodule.c: In function `pythonify_res_fields': ./MySQLmodule.c:384: invalid lvalue in unary `&' ./MySQLmodule.c: In function `STH_fetchdict': ./MySQLmodule.c:1125: invalid lvalue in unary `&' ./MySQLmodule.c:1147: invalid lvalue in unary `&' make: *** [MySQLmodule.o] Error 1 As far as I can see, I'm not getting any errors about missing includes and it's not getting to the link step, so I don't know if I'm missing any libraries. mysql was installed via rpm. Any pointers or help appreciated....

Looking up object instances in a folder
by Marius Kjeldahl 19 Mar '00

19 Mar '00

I have some instances of my own ZClass in a folder, and I can iterate over them using: <dtml-in "somefolder.subfolder.objectValues()"> <dtml-var title> </dtml> The instances are stored using auto generated ids (simple numbers). In addition to being able to iterate over the instances in the folder, I also need to access an instance directly by using its id which is passed in the REQUEST object, but so far I have been unsuccessful. What I am trying to do is something like: <dtml-in "somefolder.subfolder.getInstance(REQUEST.id)"> <dtml-var title> </dtml-in> but I have not been able to get access to just the one instance (but iterating works fine as mentioned before). Could somebody with a clue give me a hint? Thanks in advance, Marius Kjeldahl

I tried to use MySQLDA without success. I have a redhat 6.1 and MySQL 3.22.29 installed. I even installed a unixODBC connection to MySQL that works. How can I access this database through ZOPE. When I try to make the MySQLDA extension a lot of errors come out of it : gcc -fPIC -I/usr/local/mysql-3.22.32/include/ -I/usr/include/mysql -g -O2 -I/us r/include/python1.5 -I/usr/include/python1.5 -DHAVE_CONFIG_H -c ./MySQLmodule.c ./MySQLmodule.c: In function `pythonify_row': ./MySQLmodule.c:238: warning: assignment from incompatible pointer type ./MySQLmodule.c: In function `pythonify_res_fields': ./MySQLmodule.c:384: invalid lvalue in unary `&' ./MySQLmodule.c: In function `STH_fetchdict': ./MySQLmodule.c:1125: invalid lvalue in unary `&' ./MySQLmodule.c:1147: invalid lvalue in unary `&' make: *** [MySQLmodule.o] Error 1 Can you help me ?
