我有以下型号

class Project < ActiveRecord::Base
  has_many  :assignments, :conditions => {:deleted_at => nil}
  has_many  :members, :conditions => {:deleted_at => nil}
  accepts_nested_attributes_for :members, :allow_destroy => true
end

class Member < ActiveRecord::Base
  belongs_to :project
  belongs_to :person
  belongs_to :role

  has_many :assignments, :dependent => :destroy, :conditions => {:deleted_at => nil}
  accepts_nested_attributes_for :assignments, :allow_destroy => true


  validates_presence_of     :role_id
  validates_presence_of     :project_id
end

我假设控制器将在 project.save 上为每个嵌套成员记录填充 member.project_id。但是，我收到一个验证错误，指出 project_id 为空白。

我的控制器方法：

  def create
    # @project is created in before_filter
    if @project.save
      flash[:notice] = "Successfully created project."
      redirect_to @project
    else
      render :action => 'new'
    end
  end

我需要在每个嵌套成员记录中手动设置 project_id 吗？或者控制器在创建成员记录时需要填充什么？

像这样创建Member对象：

@member = @project.members.build
