Rails - May 2006 - Should partials have access to the same var''s as the view?

I have a view, part of it I put in to a partial - a copy paste - but now 
I get an error saying that there is an "undefined local variable or 
method" in the partial code...

Do I need to pass my var to the partial, I would have though not?

Cheers AFM

You need to pass your variables to the partial using the :locals key,
like this:

render :partial => ''my_partial'', :locals => { :foo =>
''bar'', :fro =>
''baz'' }


Then, your partial can access the local variables ''foo'' and
''fro''.

This works, thanks. I just assumed partials worked like includes, they 
must be rendered independantly from the master view.

You should only have to pass vars to a partial if they''re local. You
can
read globals and instance variables from your partial without passing 
the vars to the partial.

       bob  # local var
       @bob # instance var
       $bob # global var
