當每個用戶運行每個用戶時，爲每個用戶制定一個form_tag

Question

我正在嘗試創建一個反饋表單，每個學生可以列出2個興趣。

但是，通過下面的代碼，它僅識別上一個學生的interest_1和interest_2，並將這些值映射到所有學生，而不是每個學生的不同值。任何人都可以瞭解如何針對每個學生製作interest_1和interest_2？

<%= form_tag feedback_send_path, :method => 'post' do %> 
    <% @course.students.each do |student| %> 
    <%= avatar_for(student, :photo_size => :thumb_small, :class => 'notBig', :size => '50x50') %> 
    <%= link_to student.name, user_path(student.id), :class => "profile-link" %> 
    <%= text_area_tag 'interest_1', '', :class => 'feedback-form', :placeholder => "Wants to teach..." %> 
    <%= text_area_tag 'interest_2', '', :class => 'feedback-form', :placeholder => "Wants to learn..." %> 
    <% end %> 
<%= submit_tag "Submit", :class => "send-message-button" %> 
<% end %>

Answer 1

而不是

<%= text_area_tag 'interest_1', '', :class => 'feedback-form', :placeholder => "Wants to teach..." %> 
    <%= text_area_tag 'interest_2', '', :class => 'feedback-form', :placeholder => "Wants to learn..." %> 

使用

<%= text_area_tag 'interest_1[]', '', :class => 'feedback-form', :placeholder => "Wants to teach..." %> 
    <%= text_area_tag 'interest_2[]', '', :class => 'feedback-form', :placeholder => "Wants to learn..." %> 

然後看看你的params哈希！
