Ruby On Rails 收到错误：语法错误、意外的关键字_确保、期望输入结束

Question

我对 ruby​​ on rails 有点陌生，我正在为我正在处理的 Web 应用程序构建嵌套模型，该应用程序将具有分配给它们的目标的目标。

我正在创建一个嵌套有嵌套目标和步骤的表单，但出现错误

“语法错误，意外的keyword_ensure，期望输入结束”

    <% form_for @goal do |goal_form| %>
  <div>
    <%= goal_form.label :Goal, 'Goal:' %>
    <%= goal_form.text_field :Goal %>
  </div>
  <div>
    <%= goal_form.label :Description, 'Description:' %>
    <%= goal_form.text_area :Description %>
  </div>
  <div>
    <%= goal_form.label :Date, 'Date:' %>
    <%= goal_form.date_select :Date %>
  </div>
  <div>
    <%= goal_form.label :DueDate, 'DueDate:' %>
    <%= goal_form.date_select :DueDate %>
  </div>

  <!-- Here we call fields_for on the project_form builder instance.
       The block is called for each member of the tasks collection. -->
  <% goal_form.fields_for :steps do |step_form| %>
      <p>
        <div class="field">
          <%= step_form.label :requirement %><br>
          <%= step_form.text_field :requirement %>
        </div>

        <div class="field">
          <%= step_form.label :completionTime %><br>
          <%= step_form.number_field :completionTime %>
        </div>

        <% unless step_form.object.new_record? %>
          <div>
            <%= step_form.label :_delete, 'Remove:' %>
            <%= step_form.check_box :_delete %>
          </div>
        <% end %>
      </p>

  <% end %>
<% end %>

<div class="actions">
    <%= goal_form.submit %>
</div>

<% end %>

Answer 1

您添加了额外的<% end %>并且您的表单应该是<%= form ..... %>而不是<% form .... %>

尝试用以下代码替换上面的代码：

<%= form_for @goal do |goal_form| %>
  <div>
    <%= goal_form.label :Goal, 'Goal:' %>
    <%= goal_form.text_field :Goal %>
  </div>
  <div>
    <%= goal_form.label :Description, 'Description:' %>
    <%= goal_form.text_area :Description %>
  </div>
  <div>
    <%= goal_form.label :Date, 'Date:' %>
    <%= goal_form.date_select :Date %>
  </div>
  <div>
    <%= goal_form.label :DueDate, 'DueDate:' %>
    <%= goal_form.date_select :DueDate %>
  </div>

  <!-- Here we call fields_for on the project_form builder instance.
       The block is called for each member of the tasks collection. -->
  <% goal_form.fields_for :steps do |step_form| %>
    <p>
    <div class="field">
      <%= step_form.label :requirement %><br>
      <%= step_form.text_field :requirement %>
    </div>

    <div class="field">
      <%= step_form.label :completionTime %><br>
      <%= step_form.number_field :completionTime %>
    </div>

    <% unless step_form.object.new_record? %>
      <div>
        <%= step_form.label :_delete, 'Remove:' %>
        <%= step_form.check_box :_delete %>
      </div>
    <% end %>
    </p>

  <% end %>
  <div class="actions">
    <%= goal_form.submit %>
  </div>
<% end %>

<%= form_for @goal do |goal_form| %>
  <div>
    <%= goal_form.label :Goal, 'Goal:' %>
    <%= goal_form.text_field :Goal %>
  </div>
  <div>
    <%= goal_form.label :Description, 'Description:' %>
    <%= goal_form.text_area :Description %>
  </div>
  <div>
    <%= goal_form.label :Date, 'Date:' %>
    <%= goal_form.date_select :Date %>
  </div>
  <div>
    <%= goal_form.label :DueDate, 'DueDate:' %>
    <%= goal_form.date_select :DueDate %>

  <!-- Here we call fields_for on the project_form builder instance.
       The block is called for each member of the tasks collection. -->
  <% goal_form.fields_for :steps do |step_form| %>
    <p>
    <div class="field">
      <%= step_form.label :requirement %><br>
      <%= step_form.text_field :requirement %>
    </div>

    <div class="field">
      <%= step_form.label :completionTime %><br>
      <%= step_form.number_field :completionTime %>
    </div>

    <% unless step_form.object.new_record? %>
