Rails - Mar 2008 - The controller.send() method failing to assign value

Hi there.

I have a conroller, on which I''m using the send() method to find the
correct property to assign a posted value to. This looks like so:

[code]
@charactersheets.send(abl) = v
[/code]

Where the abl variable is defined earlier, and is a method. And the v
variable is a post value assigned earlier. I used to use a switch-case
to assign the value, and that worked fine, but this should save time,
why does it not work? I get the following error:

[code]
SyntaxError in CharactersheetsController#show

/Users/emil/Sites/ror/dnd/app/controllers/charactersheets_controller.rb:501:
syntax error, unexpected ''='', expecting kEND
      @charactersheets.send(abl) = v
                                  ^
RAILS_ROOT: ./script/../config/..

because the result of a method call like that isn''t an assignable  
value. It''s like writing Math.sqrt(4)=3, you just can''t do it.
Assuming the variable name is foo, what you need to do is call the  
foo= method, passing v as the argument.
