控制器沒有創建關聯

Question

我有兩個模型，用戶和組織，它們使用賦值表具有has_many關係。當創建用戶時，我有一個嵌套的資源表單，這就創建了一個關聯的組織。但是，創建組織時，它不會將其與用戶關聯。

這裏是我的相關組織控制器代碼：

def new 
    @organization = current_user.organizations.build 
    end 

    def create 
    @organization = current_user.organizations.build(params[:organization]) 
    @organization.save 
    end 

而且我的模型：

組織分配

class OrganizationAssignment < ActiveRecord::Base 
    belongs_to :user 
    belongs_to :organization 

    attr_accessible :user_id, :organization_id 
end 

組織：

class Organization < ActiveRecord::Base 
    validates :subdomain, :presence => true, :uniqueness => true 

    has_many :organization_assignments 
    has_many :people 
    has_many :users, :through => :organization_assignments 

    attr_accessible :name, :subdomain 
end 

用戶：

class User < ActiveRecord::Base 

    has_many :organization_assignments 
    has_many :organizations, :through => :organization_assignments 

    # Include default devise modules. Others available are: 
    # :token_authenticatable, :confirmable, 
    # :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 

    accepts_nested_attributes_for :organizations 

    # Setup accessible (or protected) attributes for your model 
    attr_accessible :email, :password, :password_confirmation, :remember_me, :organizations_attributes 
    # attr_accessible :title, :body 

end 

表單視圖：

= form_for @organization, :html => { :class => 'form-horizontal' } do |f| 
    - @organization.errors.full_messages.each do |msg| 
    .alert.alert-error 
     %h3 
     = pluralize(@organization.errors.count, 'error') 
     prohibited this user from being saved: 
     %ul 
     %li 
      = msg 

    = f.label :name 
    = f.text_field :name 

    = f.label :subdomain 
    = f.text_field :subdomain 

    .form-actions 
    = f.submit nil, :class => 'btn btn-primary' 
    = link_to t('.cancel', :default => t("helpers.links.cancel")), organizations_path, :class => 'btn' 

我能夠在控制檯事後精細組織聯繫起來，所以我敢肯定的關係在模型中正確設置。還有什麼我失蹤？

根據我對Rails的經驗，你不能指望這種關係。嘗試這樣的事情。

def create 
    @organization = Organization.build(params[:organization]) 
    @organization.save 

    current_user.organizations << @organization 
end 

你可能或者讓你的代碼，是的，但保存current_user而不是@organization。

def create 
    @organization = current_user.organizations.build(params[:organization]) 
    current_user.save 
end
