I am currently browsing the API Reference section of the Zope book and am trying simple examples. I am puzzled as to how various methods may be accessed from dtml. For instance the line: <dtml-var expr="getSize()"> works fine, but: <dtml-var expr="dow()"> (which I would have expected to return the day of week) gives an error Obviously I am confused. Could somebody try and put me on the right tracks! TIA Dave.
When you call something from DTML, the "namespace" is searched for the name you're trying to access (in your cases, getSize and dow). The rules for this namespace search are byzantine, and even I don't know them. The intent, however, is for you to *not* have to know them (though this fails miserably sometimes). While getSize is an attribute of most Zope objects (and can usually be acquired as well), it's generally found easily in the namespace. However, IIRC, 'dow' is a method of ZopeTime objects, so youd either need to put "dow" into the namespace explicitly: <dtml-with "ZopeTime()"> <dtml-var dow> </dtml-with> Or call it directly on an instance: <dtml-var "ZopeTime().dow()"> HTH, - C David Lambert wrote:

Chris, Thanks, that works fine. Now can you guide me to the appropriate documentation for finding the names of objects such as ZopeTime. I had been trying to access these methods by using DateTime which I guess is the Python equivalent? Maybe I'm still a little confused. TA Dave. On Friday 03 August 2001 08:37, Chris McDonough wrote:

Hey David, Check out ZopeLabs. There's a "recipe" there that shows you how to use many different ZopeTime incantations.
