Question

我有以下集合选择，它在Rails应用程序中充当过滤器。

<%= form_tag( "/appointments", :method => "get", :id => "filter_form") do %>
   <%= collection_select :doctor, :id, @doctors, :id, :full_name, {:include_blank => 'All'} %>
<% end %>

这总是会生成select name="doctor[id]"之类的select元素的name属性，从而导致浏览器显示?utf8=✓&doctor%5Bid%5D=1，而且不太可读。

如何将name属性更改为name = "doctor"或基本上只删除括号？

Answer 1

http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-collection_select

collection_select方法包含参数“options”和“html_options”。 “选项”允许您添加特定信息，例如{:include_blank => 'All'}，但不替换html属性。

您必须将名称添加到下一个哈希，如下所示：

<%= form_tag( "/appointments", :method => "get", :id => "filter_form") do %>
   <%= collection_select :doctor, :id, @doctors, :id, :full_name, {:include_blank => 'All'}, {:name => 'doctor'} %>
<% end %>

Answer 2

你试过了吗？

<%= form_tag( "/appointments", :method => "get", :id => "filter_form") do %>
    <%= collection_select :doctor, :id, @doctors, :id, :full_name, {:include_blank => 'All', :name => 'doctor'} %>
<% end %>

Rails collection_select自定义名称属性
