Question

我不想禁用collection_select并且已经测试了以下代码：

<%= 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) %>

他们都不工作，有谁知道为什么？

来自rails文档

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

请注意，html选项属性之前有一个选项属性。如果您没有定义任何选项，则必须在定义任何html选项之前包含空括号。

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

如何在rails 4中禁用collection_select
