I have been puzzling over how to apply Python scripts to various kinds of things in a page template. A simple example is a script I have called formatContactName that takes a name record and formats it as "last, first middle title suffix". In a page template this would get used like so: <span tal:content="object/formatContactName">placeholder</span> It appears that I can only do this for a very limited class of objects: It works fine for records obtained from a database query in the template itself, but it does _not_ work for a dictionary obtained from a SESSION variable or from the options parameter. Nor does it work for a page template. I currently use a table display macro for displaying database queries and I am having to pass in a list of column specifications via the options parameter which means that I am keeping display information in the form's Python script (bad design). My tentative solution was to add list properties (describing the columns) to the page and then write a script to turn the list of column descriptor fields into a list of rows of single column descriptions. I wrote the script (list_columns ) and tried to call it as above: <... tal:define="list_columns template/list_columns"...> and again I got a name resolution problem. This is a very handy facility, and I would like to make more use of it (writing methods like this to expand simple dictionaries is very appealing) but it seems to be mostly unavailable.
