Rails 3.1, passing parameters for colection_select from controller

Question

I have this collection_select usage in my view:

<%= collection_select(:production_year, :id, @car_models, :id, :name, { :prompt => "Year" }, { :disabled => "disabled" } ) %>

But it seems, that i'll add much logic for this select box. So i want pass parameters for this collection_select from my controller. How can i do this?

Was trying to pass array with parameters, but got many errors. Pls show correct way for this.

Answer 1

In your controller: @collection_select_params = [ ... ]

And in your view: <%= collection_select(*@collection_select_params) %>

The * prefix will indicate to ruby that this array is to be passed as an args list.
