Rails 3.1，从控制器传递 colection_select 参数
我认为有这个 collection_select 用法：
<%= collection_select(:production_year, :id, @car_models, :id, :name, { :prompt => "Year" }, { :disabled => "disabled" } ) %>
但看来，我会为此选择框添加很多逻辑。所以我想从我的控制器传递这个 collection_select 的参数。我该怎么做？
试图传递带有参数的数组，但出现了很多错误。请显示正确的方法。
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.

在您的控制器中：
@collection_select_params = [ ... ]在您的视图中：
<%= collection_select(*@collection_select_params) %>*< /code> 前缀将向 ruby 指示该数组将作为参数列表传递。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.
