意外的keyword_ensure,預期輸入結束

[英]unexpected keyword_ensure, expecting end-of-input

我是Ruby on Rails的新手,我試圖創建一個具有群組的網站,群組具有帖子,帖子具有評論,每當我嘗試運行我的代碼時,它都會顯示以下錯誤:

語法錯誤,意外的keyword_ensure,期望輸入結束指向注釋視圖中這部分代碼:

    <h2>Add a comment:</h2>
    <%= render'comments/form' %>

誰能告訴我我的代碼有什么問題嗎?

這是我的代碼:

組顯示視圖:

    <p>
      <strong>Name:</strong>
      <%= @group.name %>
    </p>

    <p>
      <strong>Description:</strong>
      <%= @group.description %>
    </p>

    <p>
      <strong>Interest:</strong>
      <%= @group.interest %>
    </p>


    <h2>Posts</h2>
    <% @group.posts.each do |post| %>
      <% @post = post %>
      <% if @post != nil %>
        <%= render 'posts/post',  :collection => @group.posts%>
      <% end %> 
    <% end %>

    <h2>Add a Post</h2>
    <%= render 'posts/new' %>

    <%= link_to 'Edit', edit_group_path(@group) %> |
    <%= link_to 'Back', groups_path %>
    <%= link_to 'Destroy', edit_group_path, method: :delete, data: { confirm: 'Are you sure?' } %>

_post.html.erb:

    <p>
      <strong>Title:</strong>
      <%= @post.title %>
    </p>

    <p>
      <strong>Text:</strong>
      <%= @post.text %>
    </p>

     <h2>Comments:</h2>
     <% @post.comments.each do |comment| %>
        <% @comment = comment %>
        <% if @comment != nil %>
            <%= render 'comments/comment',  :collection => @post.comments%>
        <% end %>
      <% end %>

    <h2>Add a comment:</h2>
    <%= render 'comments/form' %>


    <%= link_to 'Show', comment %>
    <%= link_to 'Edit', edit_group_post_path(p@ost) %>
    <%= link_to 'Destroy', edit_group_post_path, method: :delete, data: { confirm: 'Are you sure?' } %>

帖子:_form.html.erb:

    <%= form_for(@post) do |f| %>
  <% if @post.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@post.errors.count, "error") %> prohibited this post from being saved:</h2>

      <ul>
      <% @post.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <h2>Add a post:</h2>
<%= form_for([@group, @group.posts.build]) do |f| %>
  <p>
    <%= f.label :Title %><br>
    <%= f.text_field :title %>
  </p>
  <p>
    <%= f.label :Text %><br>
    <%= f.text_area :text %>
  </p>
  <p>
    <%= f.submit %>
  </p>
<% end %>

_comment.html.erb:

      <p>
        <strong>Commenter:</strong>
        <%= @comment.commenter %>
      </p>

      <p>
        <strong>Comment:</strong>
        <%= @comment.comment %>
      </p>


    <%= link_to 'Edit', edit_group_post_comment_path(@comment) %>
    <%= link_to 'Destroy', edit_group_post_comment_path, method: :delete, data: { confirm: 'Are you sure?' } %>

評論:_form.html.erb:

     <%= form_for([@group,@post, @post.comments.build]) do |f| %>
        <p>
          <%= f.label :comment %><br>
          <%= f.text_area :comment %>
        </p>
        <p>
           <%= f.submit %>
        </p>
      <% end %>
    <% end %> 

您不會關閉posts/_form.html.erb的第一個form_for塊。

<%= form_for(@post) do |f| %>
  <% if @post.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@post.errors.count, "error") %> prohibited this post from being saved:</h2>

      <ul>
      <% @post.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
<% end %>   <---- you're missing this tag

嘗試用render('comments/form')替換render'comments/form' 或嘗試在函數名稱和參數之間添加一個空格,如下所示: render 'comments/form'

posts: _form.html.erb:

在本部分中,您使用了兩種形式,但僅關閉了一種形式,即第二種形式。 因此,您需要關閉第一個表單助手。

<%= form_for(@post) do |f| %>
      <% if @post.errors.any? %>
       <div id="error_explanation">
        <h2><%= pluralize(@post.errors.count, "error") %> prohibited this post from being saved:</h2>

        <ul>
         <% @post.errors.full_messages.each do |msg| %>
          <li><%= msg %></li>
        <% end %>
        </ul>
       </div>
     <% end %>
     <% end %>       <!-- You are missing this end in posts: _form.html.erb and also you have another problem -->

comments: _form.html.erb:

在此部分中,您兩次關閉表單,因此只需刪除一個<%end%>

     <%= form_for([@group,@post, @post.comments.build]) do |f| %>
        <p>
          <%= f.label :comment %><br>
          <%= f.text_area :comment %>
        </p>
        <p>
           <%= f.submit %>
        </p>
      <% end %>
    <!-- remove last "end" as it is an extra closing
