Ruby on rails 使嵌套属性在rails api only应用程序中工作

我有一个只有rails api的应用程序，其中有两个模型。 我正在使用Desive_auth_令牌进行身份验证

class User < ActiveRecord::Base
  # attr_accessible :accounts_attributes
  has_many :accounts
  accepts_nested_attributes_for :accounts
  # Include default devise modules.
  devise :database_authenticatable, :registerable,
          :recoverable, :rememberable, :trackable, :validatable,
          :omniauthable
  include DeviseTokenAuth::Concerns::User
  #Deleted ":confirmable," from above
  after_create :assign_member_role

  private
  def assign_member_role
    mr = MemberRole.first # default MR
    Member.create!(user_id: self.id, member_role_id: mr.id)
  end

  def populate_account

  end

end

我正在尝试用json创建一个新用户。我想在每个用户创建的帐户模型上完成填充

如果我在注册控制器中使用以下代码

before_filter :user_params
  puts "hello"

  GET /users/sign_up
  def new

    # Override Devise default behaviour and create a profile as well
    build_resource({})
    resource.build_account
    respond_with self.resource
  end

  def create
    puts "\n\n Testing if the create method can be overriden\n\n"
    puts params.inspect
    params.require(:users).permit!
    super
  end

  protected

  def user_params
    puts "in loop\n\n\n\n"
    devise_parameter_sanitizer.for(:sign_up) { |u|
      # u.permit(:email, :password, :password_confirmation, :accounts_attributes => :school_name)
      u.permit(:email, :password, :password_confirmation, :accounts_attributes[:school_name, :line_1, :line_2, :city, :state, :country, :pincode])
    }
    # params.require(:user).permit(:email, :password, :password_confirmation, :accounts_attributes[:school_name, :line_1, :line_2, :city, :state, :country, :pincode])
  end
end

我可以创建新用户，但无法填充帐户模型。并在我的终端中获取未知参数错误和参数丢失错误，如下所示

嗯，你应该有一个自己的api控制器，因为你想控制你的api。不要使用常规的控制器进行控制api@huanson那么，我是否应该放弃使用任何宝石进行身份验证呢？好吧，这取决于你和你的需要。只是说您需要自己的Api名称空间和控制器，其中Api的每个控制器都继承自您自己的Api:：BaseControler（而不是应用程序\控制器）。您还希望从您的versions控制器继承，因此您可以说您发布了一个/api/v2/，其中您只更改了一个模型的某些行为，但其他所有行为仍然是v1。ryan bates在如何对API进行版本化方面有一个很好的railscast
