Brain Lloyd has a couple of patches that will probably sort this out. Chris Andy Pahne wrote:
hi,
at the moment we are builduing a database-enabled three-language website. we have the contents (texts) for the site already in a database. I wrote a Z-SQL-Method sql_get_text which takes id_to_get as argument. So, when I call
<dtml-in "get_text(id_to_get=xxxx)"> <dtml-var text_value> </dtml-in>
I get the text I was looking for. (Note that this ZSQL-method will return only one result, because id_to_get is the primary key of the database table and therefore unique).
I wanted to make things a bit easier for the people who generate the templates for the site. So I coded a helper-method named get_text which also takes id_to_get as argument. It holds exactly the code-snippet from above. By doing so I wanted the HTML-Coders to type
<dtml-var "get_text(id_to_get=xxxx)">
so that they do not have to worry about the dtml-in-tag. It did not work. I get an error-message that Zope can not find the ZSQL-method sql_get_text method. Here is the traceback:

My next idea was:
<dtml-with REQUEST> <dtml-in "get_text(id_to_get=xxxx)"> <dtml-var text_value> </dtml-in> </dtml-with>
I don't know why, but the <dtml-with REQUEST> fixed a lot of errors before, so I just gave it a try. But then I received and error-message telling me that I am trying to refference the non-existing object REQUEST.
Now, why doesn't it find my method and why did the REQUEST-object disappear???
PS: I am doing Zope for half a year now but the namespace-stack is still mysterious to me.
