如何在Rails 4中禁用collection_select

Question

我不會禁用collection_select並已經測試了以下代碼：

<%= f.collection_select(:categoria_id, Categoria.order(:descricao), :id, :descricao,{ class: "form-control", :disabled => "disabled" }) %>
<%= f.collection_select(:categoria_id, Categoria.order(:descricao), :id, :descricao,{ class: "form-control", :disabled => true }) %>
<%= f.collection_select(:categoria_id, Categoria.order(:descricao), :id, :descricao, class: "form-control", :disabled => "disabled") %>
<%= f.collection_select(:categoria_id, Categoria.order(:descricao), :id, :descricao, class: "form-control", :disabled => true) %>

他們都不工作，有人知道為什么嗎？

從Rails文檔

collection_select(object, method, collection, value_method, text_method, options = {}, html_options = {}) public

請注意，在html options屬性之前有一個option屬性。 如果未定義任何選項，則必須在定義任何html選項之前包括一個大括號。

<%= f.collection_select(:categoria_id, Categoria.order(:descricao), :id, :descricao,{},{ class: "form-control", :disabled => "disabled" }) %>
