Question

我有一个注册控制器（覆盖设计控制器），它应该接收JSON哈希，然后注册一个新用户。但是，新用户保存总是失败，但我无法弄清楚原因。

这是我的控制器：

class Api::V1::RegistrationsController < Devise::RegistrationsController

  skip_before_filter :verify_authenticity_token
  respond_to :json

  def create

    @user = User.new(params[user_params])

    if @user.save
      render json: @user.as_json(auth_token: user.authentication_token, email: user.email), status: 201
      return
    else
      warden.custom_failure!
      render json: @user.errors, status: 422
    end
  end

  def user_params
    params.require[:registration].permit(:email, :password, :name, :phone, :acknowledgement) if params.present?
  end

end

我的用户模型包括电子邮件，电话，姓名和确认的验证

要测试控制器，我使用以下命令：

curl -v -H 'Content-Type: application/json' -H 'Accept: application/json' -X POST http://localhost:3000/api/v1/registrations -d "{\"email\":\"user1@example.com\",\"name\":\"anotheruser\",\"phone\":\"250.717.7265\",\"acknowledgement\":\"true\"}"

我从运行命令获得此输出：

{"email":["can't be blank","can't be blank"],"name":["can't be blank"],"phone":["can't be blank","Must be in 555.555.5555 format"],"acknowledgement":["can't be blank"]}

我的网络服务器正在给我这个输出：

Processing by Api::V1::RegistrationsController#create as JSON

显然，它并没有像我想象的那样创建新用户，但我无法弄清楚原因。如果有人能帮我看看有什么不对，我真的很感激。

将您的curl请求更改为：

curl -v -H 'Content-Type: application/json' -H 'Accept: application/json'\
 -X POST http://localhost:3000/api/v1/registrations 
\-d "{\"registration\":{\"email\":\"user1@example.com\",\"name\":\"anotheruser\",\"phone\":\"250.717.7265\",\"acknowledgement\":\"true\"}}"

您未在[{1}}方法中提供registration require

修改

变化：

user_params

为：

@user = User.new(params[user_params])

无法使用rails控制器处理传入的JSON
