I have an sql statement that given a username it returns a project.
So my first question is: Is it possible to let the statement return a
string instead of a list. i.e. 'project' instead of ['project'] ?
So, if call it from a page template, I can use
<div tal:content="python:here.project(uname=username).project" />
But if the project method returns an empty list, this statement will
fail (because of ).
So what is a smart solution to this ? I've tried putting a repeat
statement around this, and tried defining a variable called projectExist
using len on the function. This however makes the page template very
complex when calling another sql method such as:
if I'm using, say, the Python Database API I would just call fetchone()
on the cursor object. It is that functionality I am looking for.
