Question

我将字段user_name和job_function添加到使用Devise创建的用户模型中。我可以将字段添加到视图中，但这两个新字段不会保存到数据库中。仅限：保存电子邮件和：密码，这是已经发生的事情。

***** UPDATE：

我收到以下错误：未允许的参数：user_name，job_function

所以我正在考虑绕过那个。任何想法都表示赞赏。

提前感谢。

class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :authenticate_user!
            :configure_permitted_parameters, if: :devise_controller?

protected

def configure_permitted_parameters
  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:user_name, 
    :job_function)}
  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:user_name, 
    :job_function)}
  devise_parameter_sanitizer.for(:update) { |u| u.permit(:user_name, 
    :job_function)}
  end
end

Answer 1

想出来。我需要将以下内容添加到我的ApplicationController：

before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:user_name, :job_function])
  end
