清除这个show.html.erb视图(Rails)的建议？
提问于 2012-02-12 08:20:39
以下视图显示了一个帖子及其评论：
views/posts/show.html.erb:
<h2>posts show</h2>
<span>Title: <%= @post.title %></span><br />
<span>Content: <%= @post.content %></span><br />
<span>User: <%= @post.user.username %></span><br />
<div class="post-<%= @post.id %>">
<h3><span class="vote-count"><%= @post.total_votes %></span> votes</h3><br />
<div class='voted-user'>
<% @post.votes.each do |vote| %>
<%= link_to vote.user.username, vote.user %>
<% end %>
</div>
<%= link_to "Vote Up", vote_up_path(@votable, :votable_type => "Post"), :remote => true, :class => "vote-up" %><br />
<%= link_to "Vote Down", vote_down_path(@votable, :votable_type => "Post"), :remote => true, :class => "vote-down" %><br />
<h2>Comments</h2>
<p><%= link_to 'Order by Date', post_path(@post, :order_by => "created_at ASC") %></p>
<p><%= link_to 'Order by Votes', post_path(@post, :order_by => "total_votes DESC") %></p>
<% @comments.map do |comment| %>
<div class="comment-<%= comment.id %>">
<p>
<b>Comment:</b>
<%= comment.content %>
</p>
<p>
<b>Vote:</b>
<span class="vote-count"><%= comment.total_votes %></span>
<div class='voted-user'>
<% comment.votes.each do |vote| %>
<%= link_to vote.user.username, vote.user %>
<% end %>
</div>
</p>
<p>
<b>Commenter</b>
<%= link_to comment.user.username, comment.user %>
</p>
<p>
<b>Link</b>
<%= link_to "Show Post Comment", [@post, comment] %>
</p>
<p>
<b>Vote</b>
<%= link_to "Vote Up", vote_up_path(comment, :votable_type => "Comment"), :remote => true, :class => "vote-up" %><br />
</p>
</div>
<% end %>
<%= will_paginate @comments %>
<h2>Add a comment:</h2>
<%= form_for([@post, @post.comments.build]) do |f| %>
<div class="field">
<%= f.label :content %><br />
<%= f.text_area :content %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
<% if current_user.id == @post.user_id %>
<%= link_to 'Edit', edit_post_path(@post) %> |
<% end %>
<%= link_to 'Back', posts_path %>我只是专注于把事情做好，所以我完全忘了把它弄干净。我是一个Rails初学者，我想要一些建议或建议来清理这个视图(如果您建议将代码移到另一个文件中，请提到文件的名称和目录)。提前谢谢。

很感谢你想把它清理干净。我也会这么做的。我在这里包含了几个例子: Partials、Helpers，还稍微清理了HTML，以允许更多地控制样式表中的样式(我忽略了这一点，但我确信您可以理解这一部分)。如果这是我的项目，我将提取更多的内容(例如，我可能会将entre“编辑/回”链接以及"Order“链接移动到它们自己的部分或助手，因为我可能会在整个应用程序的许多地方使用它们)。如果您的评论是多态的(不只是针对posts)，那么一定要将其移到它自己的视图文件中。而且，我做了一个相当快，所以它可能有一些错误，如果你发现任何遗憾。
