Railstutorial.org书，更改为嵌套路线
|
嗨，我一直在遵循Rails教程书，创建用户和帖子以及显示帖子的提要。但是，作者从未使用过嵌套资源，嵌套资源在rails中似乎非常重要，我想发现如何自己使用它们。但是，当我根据Ruby on Rails指南嵌套post资源时，它随后破坏了我的所有表单和路径。
与其从头开始，我不希望切换到嵌套资源，并在此过程中确切了解差异。谁能帮我解决这个问题？谢谢你的帮助。
特别是我对如何处理提要感到困惑。当前feed_item调用旧的post_path。
共享/ _feed_item部分
<tr>
<td class=\"avatar\">
<%= link_to avatar_for(feed_item.user), feed_item.user %>
</td>
<td class=\"post\">
<span class=\"title\"><%= link_to feed_item.title, feed_item %></span><br />
<span class=\"content\">the plot: <%= feed_item.content %></span><br />
<span class=\"timestamp\">
Posted <%= time_ago_in_words(feed_item.created_at) %> ago.
</span>
</td>
</td>
<% if current_user?(feed_item.user) %>
<td>
<%= link_to \"delete\", feed_item, :method => :delete,
:confirm => \"You sure?\",
:title => feed_item.content %>
</td>
<% end %>
</tr>
class Micropost < ActiveRecord::Base
.
.
.
default_scope :order => \'microposts.created_at DESC\'
# Return microposts from the users being followed by the given user.
scope :from_users_followed_by, lambda { |user| followed_by(user) }
private
# Return an SQL condition for users followed by the given user.
# We include the user\'s own id as well.
def self.followed_by(user)
followed_ids = %(SELECT followed_id FROM relationships
WHERE follower_id = :user_id)
where(\"user_id IN (#{followed_ids}) OR user_id = :user_id\",
{ :user_id => user })
end
end
