我是 Rails 新手，需要一些指导。我确定我误解了一些明显的东西。

我希望发表评论的人的用户名显示在查看页面上。我有一个部分通过对特定对象（例如学校）的评论收集。我不知道如何将该用户变量传递给部分，以便我可以显示评论的登录名。我的 Comments 模型是多态的，我很确定这会使它变得更加复杂。

以下是模型：

class Comment < ActiveRecord::Base
belongs_to :commentable, :polymorphic => true
has_many :comments, :through => :schools

class School < ActiveRecord::Base
belongs_to :installation
belongs_to :neighborhood
has_many :comments, :as => :commentable

class User < ActiveRecord::Base
has_many :users, :through => :schools

学校负责人：

def show
  @installation = Installation.find(params[:installation_id])
  @school = School.find(params[:id])
  @neighborhood = @school.neighborhood
  @comment = @school.comments
respond_to do |format|
  format.html # show.html.erb
  format.xml  { render :xml => @school }
  end
end

部分评论：

<div class="box-one">
<img src="/images/comment_top.png" alt="" />
<div class="inside">
    <p><span class="stars"><%= display_stars(comment.stars) %></span><br />
<%= comment.content %></p>  
</div>
<img src="/images/comment_bottom.png" alt="" />
</div>

学校观点：

<%= render :partial => "shared/comment", :collection => @comment %>

我认为您的模型可能存在一些问题，但是您使用locals.

<%= render :partial => "shared/comment", :locals => { :user => your_user } %>

然后在部分内部，您可以访问用户变量。

<p><span class="stars"><%= display_stars(comment.stars) %></span><br />
<%= comment.content %><br />
by <%= user %></p>

例如来自我

def show 
@school = School.find_by_id_and_user_id(params[:id],
params[:user_id],:include => [:user, [:comments => :user]])
end

class Comment < ActiveRecord::Base
  belongs_to :school, :counter_cache => true
  belongs_to :user
end

class School < ActiveRecord::Base
  belongs_to :user, :counter_cache => true
  has_many :comments

  def after_save
   self.user.update_attribute(:last_activity, "bla bla bla")
   self.user.update_attribute(:last_activity_at, Time.now)
  end
end

 class User
   has_many :school or has_one
   has_many :comments
 end

<div class="box-one">
<img src="/images/comment_top.png" alt="" />
<div class="inside">
        <% @schools.comments.each do |comment| -%>
        <%= comment.created_at.to_s(:short) %>  
        <p><span class="stars"><%= <%= comment.user.stars %> said: ## or<%= comment.user.username %> said:##</p> %></span><br />
<%= comment.content %></p>  

</div>
<img src="/images/comment_bottom.png" alt="" />
</div>

<%= render :partial => "shared/comment"%>
