如何使用remote_function将主题参数发送到控制器？
|
假设这种形式：
<% form_for(@student) do |f| %>
<%= f.select(:subject_id,
options_from_collection_for_select(@subjects, :id, :name),
{:prompt => \'Select a subject\' },
{:onChange => \"#{remote_function(:update => :student_exam_id,
:url => {
:action => :update_exams_list,
:subject_id => 1
}
)
}\" } ) %>
<%= f.select(:exam_id,
options_from_collection_for_select(@exams, :id, :title) ) %>
<% end %>
:subject_id => 1
