我有我想告诉所有用户的个人资料及其相关的照片索引页。我使用的插件回形针的照片。在情景模式控制器，我有实例变量@profile，但它让我看到表中的配置文件表，而不是只在照片表。

I have an index page that I want to show all the users' profile and their associated photos. I'm using the plugin Paperclip for the photos. In the Profiles controller, I have the instance variable @profile but it shows me the table in the profiles table only and not the photos table.

@profile = Profile.find(:all, :include => :photos,
  :joins => "INNER JOIN photos ON photos.profile_id = profiles.id")

的模型如下所示：

The models are shown below:

class Profile < ActiveRecord::Base
  has_many :photos
end

class Photo < ActiveRecord::Base
  belongs_to :profile
end

我希望能够在视图中显示是这样的：

What I want to be able to show in the View is something like:

我已经编辑我的答案，以反映你的额外的意见。

I've edited my answer to reflect your extra comments.

首先，你应该不需要：加入参数; ：包括=＆GT; ：照片应处理好加入幕后为您服务。

First of all, you shouldn't need the :joins parameter; :include => :photos should handle the join "behind the scenes" for you.

下面是做你问有关的一种方式。

Here's one way to do what you're asking about.

（在模型中）

class Profile < ActiveRecord::Base
  has_many :photos
  has_one :primary_photo, :class_name => "Photo", :conditions => {:primary => true}
end

（在控制器）

(in the controller)

@profiles = Profile.find(:all, :include => :primary_photo)

（在视图中）

(in the view)

<% @profiles.each do |profile| %>
  Name: <%= profile.name %>
  Age: <%= profile.age %>
  Photo: <%= image_tag profile.primary_photo.url %>
<% end %>
