Question

在我的铁路3号座标中,每个用户的概况都有我想要补充的阵列。这些项目是独一无二的,但在每个简介中增加两类。然而,我感到不安的是,通过他们的身份证将项目简介与项目联系起来。

<>strongprofile>rb Model:

class Profile < ActiveRecord::Base
  belongs_to :user
  accepts_nested_attributes_for :user

  has_many :profile_todos
  has_many :todos, :through => :profile_todos

  def add_todo_inside_item(item)
    self.profile_todos.build :category =>  inside 
  end

  def add_todo_outside_item(item)
    self.profile_todos.build :category =>  outside 
  end
end

todo.rb 模式:

class Todo < ActiveRecord::Base
  belongs_to :profile
end

profile_todo.rb 模式:

class ProfileTodo < ActiveRecord::Base
  belongs_to :profile
  belongs_to :todo
end

<><><>Todo.new >提供以下信息:

>> Todo.new
=> #<Todo id: nil, name: nil, created_at: nil, updated_at: nil>

<><>Profile Todo.new 内容如下:。

>> ProfileTodo.new
=> #<ProfileTodo id: nil, category: nil, profile_id: nil, created_at: nil, updated_at: nil>

www.un.org/Depts/DGACM/index_spanish.htm I m 电话profile_todos in my profiles using:

<div id="todosheader">
  <p><%= @profile.first_name %>&nbsp;has&nbsp;<%= pluralize(@profile.profile_todos.count,  todo ) %>.</p>
</div>
<div id="todo-list">
  <div class="todos_inside">
    <h4>Inside&nbsp;(<%= @profile.profile_todos(:category => "inside").count %>)</h4>
    <p><%= @profile.profile_todos(:category => "outside") %></p>
  </div>
  <div class="todos_outside">
    <h4>Outside&nbsp;(<%= @profile.profile_todos(:category => "outside").count %>)</h4>
    <p><%= @profile.profile_todos(:category => "outside") %></p>
  </div>
</div>

如何在<代码>的简介中添加<代码>todo。 Todo: 姓名添加到: 类别/代码>上。现在叫@profile.profile_todos的右边是空洞的。

请允许我说,我有“试验”一词,有“1”。如果我试图在我的<编码>上添加<代码>Todo。使用<条码>@profile.add_todo_inside_item(“试验”)的阵列,我看上去“试验”(<条码>,Todo到我的<条码>上> 插图_todos(类别=>“inside”)。

我不敢肯定你们想要做些什么。

to应当是复数,你应当拯救父母。

class Profile < ActiveRecord::Base
    has_many :todos

    def new_inside_todo(params)  # takes a hash of all attributes, like new()
      params.merge!( {:category => "inside"} )
      self.todos.build( params )
      self.save(:validate => false)
    end

    def new_outside_todo(params)
      params.merge!( {:category => "outside"} )
      self.todos.build( params )
      self.save(:validate => false)
    end
end

class Todo < ActiveRecord::Base
   belongs_to :profile

   # has an attribute called category

   # if Todos belong to more than one class, make the relationship polymorphic
   #     belongs_to :parent , :polymorphic => true
end
