Question

我已经好几天了，无法弄清楚问题。当我尝试注册时，它似乎工作，但是当我检查rails控制台时，它没有显示用户名。我可以从那里添加一个并且它工作正常，但使用我的注册视图它永远不会工作。只有安装Devise时创建的字段才有效。我还添加了名字和姓氏，但我只是尝试使用户名工作，因此名称代码不完整。如果我遗漏了任何重要信息，请告诉我。我真的非常感谢你的帮助。

class ApplicationController < ActionController::Base

# For APIs, you may want to use :null_session instead.

protect_from_forgery with: :exception


  protected


  def configure_devise_permitted_parameters
      devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:email, :username, :password, :password_confirmation)
  end
end

class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,

    conditions = warden_conditions.dup
    login = conditions.delete(:login)
    where(conditions).where(["lower(username) = :value", { :value => login.downcase }]).first
end

。 class UsersController＆lt; ApplicationController的 before_action：set_user，only：[：show，：edit，：update，：destroy]

架构：

create_table "users", force: true do |t|
  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.string   "current_sign_in_ip"
  t.string   "last_sign_in_ip"
  t.datetime "created_at"
  t.datetime "updated_at"
  t.string   "first_name"
  t.string   "last_name"
  t.string   "username"
end

   add_index "users", ["email"], name: "index_users_on_email", unique: true, using: :btree
   add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true, using:     :btree

将其添加到ApplicationController

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

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) << :username
  end
end
