[Zope-dev] Return variables from a DTML Method

[bentzion]

I want to change some ZClass properties by getting return results 
from a DTML Method. Something like this: dtml-call 
"myzclass.propertysheets.get('Basic').manage_changeProperties(dtmlM
eth(this(),_))". How do I get the dtmlMeth to return a Mapping? 
(or should I be doing this a different way?)

Thanks.

[Zope-dev] Create Virtual DataSkin

[bentzion]

This simple issue is driving me crazy...
I am trying to create a DataSkin with some Properties in a MySQL 
database. So I have an ID, NAME, and DESCRIPTION that is in REQUEST 
and using:

dtml-let ni="newItem(key=REQUEST['key'])"
  nips="ni.propertysheets.get('Basic')"
dtml-call "nips.manage_changeProperties(REQUEST=REQUEST)"
/dtml-let

The item gets created but the Properties are not changed.

Can someone please post the ADD/CHNAGE Trigger syntax and 
accompanying ZSQL Methods for a simple creation of a DataSkin 
ZClass.

Much appreciated.

[Zope-dev] More ZPatterns confusion

[bentzion]

I am trying to add a ZClass with a DataSkin Property sheet to a 
Virtual Rack. So I call the following:
dtml-let ni="newItem(key=REQUEST['key'])"
  props="ni.propertysheets.get('Basic')"
dtml-call "props.manage_changeProperties(REQUEST.form)"
/dtml-let

I assume this should call ADDED and CHANGE trigger's to place data 
in my SQL Database.
Unfortunately this is not happening. The ADDED trigger is doing the 
initial creation, but the changeProperties is not effecting the 
right changes. It seems that the CHANGE trigger is not getting 
called.

Is there something else I should be doing?
Thanks for all the help

RE: [Zope-dev] ZPatterns Project Help!

[bentzion]

Thanks for answering Steve.

Unfortunitly I am working with version 0.3 of ZPatterns so I have 
to use GAP. 

When I try to translate your Skinscript into GAP like this 
"attrsexprs:account_object=(RESULT is _.None) and NOT_FOUND or 
RESULT" and I try to access the object's id with dtml-var 
"account_object.id" I get a "NameError" on account_object. 
Alternativly if I do dtml-var account_object I get a "KeyError". 

(BTW. for testing I used "accounts.getItem('1434')" which is a 
valid object. If I do "account_object=RESULT.id" it works fine.)

I appreciate any help on this.

Hi Ben,
GAPs are sort of deprecated at this point in favor
of SkinScript. In SkinScript you might do something like this: 

WITH accounts.getItem(self.account_id) COMPUTE 
account_object=RESULT 
or more carefully... 

WITH accounts.getItem(self.account_id) COMPUTE 
account_object=(RESULT is _.None) and NOT_FOUND or RESULT

[Zope-dev] ZPatterns Project Help!

[bentzion]

Another question...

I want to have a GAP that will add some other Object to an 
attribute of my DataSkin. This is what I have tried with no 
success.

fromexpr: accounts.getItem(self.account_id)
attrsexprs: account_object=RESULT

This way in my UI Methods in my DataSkin I can access (and change) 
the attributes of "account_object".

Q. How can I do this? Should I be doing this in a different/better 
way?

Thanks,
-Ben
