This sentence doesn't make any sense.  index_hide is a boolean property of
what?  What is the particular object?

I can't give you a solution because of that, but I can give you a tip, you
don't need to say "['id']", you can just say "id".  The ['x'] syntax is
for when 'x' is not a valid name in a python expression.  'id' is valid.  
"The Nut-House" is not valid and so you would use the "['The Nut-House']"
syntax.  A valid python name is any combination of letters, numbers, or an
underscore (no spaces or any other symbols).  A name also can't start with
a number, ie 5bob is illegal, but bob5 is fine.
