我一直在努力让这个工作，以便当前登录的用户只能查看他们发布的内容。我想我几乎已经破解了它，但是我遇到了一个未定义的方法“每个”错误。
这是我编辑的仅有的两个文件：
_form.html.erb
<h1>Listing programs</h1>
<table>
<% @programs.each do |program| %>
<tr>
<td><h2><%= program.title %></h2></td>
</tr>
<tr>
<td><%= program.body %></td>
</tr>
<tr>
<td><%= link_to 'Show', program %> | <%= link_to 'Edit', edit_program_path(program) %> | <%= link_to 'Destroy', program, method: :delete, data: { confirm: 'Are you sure?' } %> </td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New Program', new_program_path %>

我目前拥有的不同模型Program是教练将发布的模型和Coach（用户）：
程序.rb：
class Program < ActiveRecord::Base
belongs_to :coach
validates_presence_of :title
attr_accessible :body, :title, :coach_id
end
教练.rb：
class Coach < ActiveRecord::Base
has_many :programs
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me, :firstname, :lastname, :coach
# attr_accessible :title, :body
end
