Rails redirect_to with params

Question

I want to pass parameters (a hash) to redirect_to, how to do this? For example:

hash = { :parm1 => "hi", :parm2 => "hi" }

and I want to redirect to page /hello

URL like this: /hello?parm1=hi&parm2=hi

Answer 1

If you don't have a named route for /hello then you'll have to hardcode the params into the string that you pass to redirect_to.

But if you had something like hello_path then you could use redirect_to hello_path(:param1 => 1, :param2 => 2)
