Friends,
I have an external method that returns a string containing dtml, but
I want it to evaluate the dtml and return the result. How do I do
that?
I noticed in, say,
/usr/share/zope/lib/python/Products/ExternalMethod/ExternalMethod.py,
that dtml-containing *files* are used as object methods like this:
from Globals import HTMLFile
manage_main = HTMLFile( 'methodEdit', globals() )
so I figured I could do a similar thing with a dtml-containing string
and an external method:
from Globals import HTML
dtml_string = '<dtml-let x="it works"><dtml-var x></dtml-let>'
external_method = HTML( dtml_string, globals() )
This in fact works, but if I try to reference anything in the current
object, like
dtml_string = '<dtml-var id>'
I get KeyError: id.
Apparently I'm getting dtml evaluation but not in the context of the
current object. What am I doing wrong, and (for extra credit) why
doesn't ExternalMethod.py have this problem using HTMLFile?
TIA,
Scott
PS: I know I can get the id with
def external_method( self, REQUEST = None ):
return self.id
but the real dtml_string I need to evaluate is much more complicated
than '<dtml-var id>'...
