[web2py] Re: format and represent on table
The problem is that table._format is used to build field.represent only for
references only when format is a string. In your case it is a function
which performs a nested query. That is very expensive. Web2py wants you to
be explicit before using it that to build a dropdown. It works (in the
first case) but it considerably slows down your code.
