Question

我正在使用will_paginate分页来调查问题。

每个问题都有答案。

每个页面包含5个问题。在转到下一页时，我丢失了上一页的答案。如何在before_paginate之前保存这些记录。

<%= form_for(@attempt, :url => attempt_scope(@attempt)) do |f| %>
   <%= f.fields_for :answers do |builder| %>
     <div id="accordion" class="questions">
       <% @questions.each_with_index do |question, index| %>
         <h3 data-id="<%= question.id %>" >Question </h3>
         <div>
          <p> <div><%= question.text %>  </div>     
        <%= hidden_field_tag "survey_attempt[answers_attributes][#{index}][question_id]", question.id %>

          </p>
         <div class="input select rating-c">
           <label for="example-c">Rating values displayed on the bars:</label>
              <%#=select_tag "survey_attempt[answers_attributes][#{index}][option_id][]", options_from_collection_for_select(@options, "id", "text"),{ class: " #{question.id}list select  mybutton",id: "example-c",include_blank: true, name: "optionname"} %>
                <%=select_tag "survey_attempt[answers_attributes][#{index}][option_id][]", options_from_collection_for_select(@options, "id", "text"),{id:"example-c"} %>
         </div>
        </div>         
       <% end %>
     </div>
     <%= will_paginate @questions, :class=>"mybutton page pagination", renderer: BootstrapPagination::Rails, params: request.params %>
  <% end %>
<%= f.submit "Submit" %>

为什么不在用户检查或选择选项时使用ajax提交答案。您可以获得有关ajax here

修改

有两种方法可以执行ajax，要么你可以去远程：你的表单中的true，我在之前发布的链接中解释过，或者你可以通过jquery调用ajax请求。我认为jquery one会更清洁。

假设您有一个问题答案的复选框。你会得到这样的东西：

<input type="checkbox" class="answers"> #but each question will have different answers so you need something to differentiate so you will need some data attribute. <input type="checkbox" class="answers" data-question="question_id">

现在，您可以通过一个jquery函数来定位每个答案，如下所示：

$(document).on("click",".answers",function(){ var question = $(this).data("question"); #gets the id of question $.ajax({ url: url_for_your_custom_action, #need to make a method in controller and create answer for that question by the id of question you get from content in params type: "POST", #a post request because you sending question id. data: { content: question } #this will send your question id. you can get it by params[:content] }); });

这样，无论用户选中哪个复选框，都会调用相同的方法，您不必重复代码。
