Hi all
I''d like to call some controller methods from other controller
methods after first modifying the params hash.
Class MyController < ApplicationController
def quirky_method
if condtion
do_stuff
else
params.merge "some_key" => "here is some new
data"
another_controller_method
end
end
the problem ive got is that the new data in the hash isn''t available
inside ''another_controller_method''. i''ve also tried
''self.params'' and
''@params'', but doesnt seem to work -whats the best way to
approach
this?
thx
glenn

It returns a new Hash which you''re just throwing away (not referencing or assigning to a variable). There is a destructive version, #merge!, which does what you want. Just add the exclamation point, and you''ll get what you''re expecting. But, I think what you should probably do is make another_controller_method accept the parameters it''s expecting as explicit arguments and call it like that. Munging params is bound to lead to some messes later on.
