角色未添加到数据库中的用户答案

【问题标题】：Role is not being added to users in database角色未添加到数据库中的用户
【发布时间】：2018-09-17 13:52:09
【问题描述】：

我在为我的 Rails Web 应用程序创建单独的用户时遇到了问题。今天，我尝试关注 Zurora 对类似帖子的回答。 https://stackoverflow.com/a/32159123

但是，现在当用户在注册页面上注册并从选项中选择一个角色时，该角色不会被写入数据库。我按照指示设置了迁移，当我检查架构时，它有一个角色条目。

但是它仍然没有被添加。这是用户在选择角色后注册时在终端中发生的情况。

这是我的 user.rb 模型

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

enum role: {person: 0, restaurant: 1, admin: 2}

has_many :posts, dependent: :destroy

validates :role, presence: true
validates :name, presence: true, length: { minimum: 4 }
validates :password, presence: true, length: { minimum: 5 }
validates :password_confirmation, presence: true, length: { minimum: 5 }

end

我的带有用户表的 schema.rb 文件

create_table "users", force: :cascade do |t|
   t.string "name", default: "", null: false
   t.string "email", default: "", null: false
   t.string "encrypted_password", default: "", null: false
   t.string "reset_password_token"
   t.datetime "reset_password_sent_at"
   t.datetime "remember_created_at"
   t.integer "sign_in_count", default: 0, null: false
   t.datetime "current_sign_in_at"
   t.datetime "last_sign_in_at"
   t.inet "current_sign_in_ip"
   t.inet "last_sign_in_ip"
   t.datetime "created_at", null: false
   t.datetime "updated_at", null: false
   t.integer "role"
   t.index ["email"], name: "index_users_on_email", unique: true
   t.index ["reset_password_token"], name:   "index_users_on_reset_password_token", unique: true
  end

迁移文件

class AddRoleToUsers < ActiveRecord::Migration[5.1]
  def change
    add_column :users, :role, :integer
  end
end

还有我的注册 html.erb 页面

<%= bootstrap_form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>

        <%= f.text_field :name,
                           placeholder: 'username (will be shown publicly)',
                           class: 'form-control' %>
        <%= f.text_field :email,
                           placeholder: 'email',
                           class: 'form-control' %>
        <%= f.password_field :password,
                              placeholder: 'password',
                              class: 'form-control' %>
        <%= f.password_field :password_confirmation,
                              placeholder: 'password confirmation',
                              class: 'form-control' %>

        <%= f.select :role, collection: User.roles.keys.to_a %>

        <%= f.submit 'Sign up', class: 'btn sign-up-button' %>
      <% end %>

在尝试修复它时，我删除了所有表，认为它没有在 postgresql 中正确更新。重新创建表并再次运行迁移。我还删除了架构文件并再次运行迁移以生成新的架构文件。

这些都没有奏效。

任何帮助将不胜感激。非常感谢

【解决方案1】：

你需要允许额外的参数

class ApplicationController < ActionController::Base
  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

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

【讨论】：

我现在添加了它，但我似乎仍然遇到同样的问题。我也尝试再次重置数据库。还是不行
没关系..我一直非常盲目和愚蠢。你是对的，我只需要在不同的控制器中定义它

【解决方案2】：

感谢 Mezbah，我考虑将角色添加到允许的参数中。

我被蒙蔽了，忽略了这一点。

我用自己的方法覆盖了注册控制器

class RegistrationsController < Devise::RegistrationsController

  private

    def sign_up_params
      params.require(:user).permit( :name,
                                :email,
                                :password, 
                                :password_confirmation)

    end

    def account_update_params
     params.require(:user).permit( :name,
                                :email,
                                :password,
                                :password_confirmation,
                                :current_password)
   end
 end

这是以前的样子。

根据 Mezbah 所说，我将其添加到此处

 class RegistrationsController < Devise::RegistrationsController

 private

def sign_up_params
  params.require(:user).permit( :name,
                                :email,
                                :password, 
                                :password_confirmation,
                                :role)
end

def account_update_params
  params.require(:user).permit( :name,
                                :email,
                                :password,
                                :password_confirmation,
                                :current_password)
end

结束

现在它可以工作了：D
