Er... OK... It works fine if I use a DTML /document/ rather than a DTML /method/. So are DTML methods totally useless or what? </flamebait>

Hello, all,

Once again, it seems I must be misunderstanding something very basic. I have a DTML method that's being called from a DTML document, and it contains the code:

<dtml-if expr="REQUEST.get(field_var)"> ... </dtml-if>

where field_var is a dtml variable that has been set to the name of another dtml variable that certainly exists in the parent document. For example, field_var == "lastname", and the parent DTML document has either received "lastname=Blah" in its request, or has done "REQUEST.set('lastname','')" if not. But the code above yeilds an error:

"global name 'REQUEST' is not defined".

Since it's defined in the parent document, shouldn't it also be defined for the DTML method? According to "The Book of Zope" the REQUEST object is defined "for the duration of the web request"; surely that must include the invocation of DTML methods within the target document?

Thanks in advance,

maybe, you should pass REQUEST explicitly, like <dtml-call "your_method(this(), REQUEST, _.None)">

Ah, now I understand. If I want to pass *any* arguments to the method, I must also explicitly pass REQUEST. But if I call the method without arguments, it will magically be passed the caller's REQUEST.
