Again: manage_afterAdd
by Tom Deprez 28 Feb '00

28 Feb '00

I've a class with a property myparent This property needs to be set after a new instance is added or when the instance is moved. Thanks to people from the list, I know I've to make an external method and add the external method manage_afterAdd to the methods of the class. This is how the method looks: def manage_afterAdd(self,item,container): item.myparent=container.id return Unfortunately, when I add a new instance and then look at the myparent property, the property is empty, while it should have a value. What am I doing wrong? tom.

dtml-tree?
by Nils Jeppe 28 Feb '00

28 Feb '00

I have a folder with some subfolders and subdocuments. I want to create a tree view of it: <dtml-var standard_html_header> <dtml-tree> <dtml-var id> </dtml-tree> <dtml-var standard_html_footer> And all Zope does is create a document with: <TABLE CELLSPACING="0"> </TABLE> in it (plus the normal headers, of course). Obviously I am doing something wrong. What is it? :-( Considering this seems to be exactly what I find in the Docs, I'm really wondering. Nils -- "Fool me seven times, shame on you.

Zope SQL Method
by Pedro Silva 28 Feb '00

28 Feb '00

Hi Zopits, I'm trying to use the Z SQL Method to create a table. I have the following code in that: CREATE TABLE Registos (Nome VARCHAR(10), Apelido VARCHAR(10), Morada VARCHAR(50), Localidade VARCHAR(30), Casa INT, Telemovel INT, Data_nasc VARCHAR(10)) When I push the Submit Query button, it gives me a error: "Syntax Error". Where could that syntax error be? I already looked to the code and I fine him right, so I can't figure where the error could be. Can anyone help me on this? Please send your answers to: psilva(a)ruido-visual.pt Thanks, Pedro

DSN-less database connection?
by Sean Kelley 28 Feb '00

28 Feb '00

I want to access a MS Access file or some other database with Zope and use SQL. How do I do this on a server that I don't control (ie- I cannot create a system DSN on my ISP which hosts Zope)?

The problem is that nothing happens! 'myparent' property keeps empty. I also don't get an error value... What do you mean by keeps empty. Is that in the sense of: <dtml-var myparent> does not yield a (the right) value? or in the sense of: I can't see the value of the property in the property screen of the instance. That last thing may happen, and still the property may be set. Try using the dtml-var in the view method of you ZClass. If you want the property to show if you consult the property tab, you may have to remap the manage_Properties (or whatever it's) called view in the ZClass definition. Rik

I ran into this with the DB setup I was using. My tables were always created fine. If you look at the code you will find that you will get a synyax error on just about anything that is not a SELECT statement. The string is passed fine however. THis is what happened to me.

Returning lists of tuples
by James W. Howe 28 Feb '00

28 Feb '00

I've got situation where I want a dtml-method to return a list of tuple objects. I then want to iterate over the tuples using a dtml-in construct, displaying the various parts of the tuple. For example, suppose I want to return a list of URL tags and names like this: <dtml-return "[('Go Here', 'foo.bar.com') , ('Go Somewhere Else', 'baz.foo.com')]"> I would like to do something like this with this result: <dtml-in urltags> <a href="< url part from tuple >">< display part of tuple ></a> </dtml-in> Is there a way to do this and if so, what is the magical syntax to make this happen? I'm also interested in knowing how I might use a collection of mapping objects in a similar manner. Thanks! James W.

(unix) permission problems with zope
by Stefan Langerman 28 Feb '00

28 Feb '00

Hi, I am trying to set up zope on a RedHat box, so that anyone in the 'zopemaster' unix group can install files (like zexp, external methods, products). Zope is run by the 'www' user, which is in the 'zopemaster' group. The UID has been set as 'www' in the z2.py file. Now, when I install a file as another user in the import directory, I set the group of the file to zopemaster, and set the permissions to g+r, zope cannot read them, and complains about a permissions problem. When the file is o+r, it works. For testing purposes, I exported a file from zope, and the group of the file was 'users'. I tried to modify the z2.py file by adding the line os.setgid(115) to the z2.py file (where 115 is the gid of 'zopemaster'), but it didn't help. Any ideas? Thanks, Stefan.

Maybe a set of guidelines or a template for docs for > user-contributed products would also be useful. This is a great idea. In fact the online help system that is currently in CVS and will be released in Zope 2.2 has support for authors of contributed products. They can use the help system to provide context sensitive help and general documentation for their products. However, I need to do more work to provide good examples for product authors. -Amos -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com
