【问题描述】：

首先，我的问题与 this one 等其他 Devise 用户名问题非常相似，但它的独特之处在于我的问题似乎是数据库。我完全希望，一旦我的问题得到回答，我会感到“呃”，但我需要第二双眼睛。

我的问题是注册过程有效，用户被保存到数据库并自动登录，除了用户名保存。除此以外，一切正常。当第一次尝试解决方案时，我认为这是一个强参数的问题，但包含用户名....所以这里是代码：

用户.rb

class User < ActiveRecord::Base
  validates :username, presence: true, uniqueness:  case_sensitive: false
  validate :validate_username

  devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable
  attr_accessor :login

  def self.find_first_by_auth_conditions(warden_conditions)
    conditions = warden_conditions.dup
    if login = conditions.delete(:username)
      where(conditions).where(["lower(username) = :value OR lower(email) = :value",  :value => login.downcase ]).first
    else
      where(conditions).first
    end
  end

  def validate_username
    if User.where(email: username).exists?
      errors.add(:username, :invalid)
    end
  end
end

application_controller.rb

class ApplicationController < ActionController::Base

  before_filter :configure_permitted_parameters, if: :devise_controller?

  protect_from_forgery with: :exception

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up)  |u| u.permit(:login, :username, :email, :password, :password_confirmation, :remember_me) 
    devise_parameter_sanitizer.for(:sign_in)  |u| u.permit(:login, :username, :email, :password, :remember_me) 
    devise_parameter_sanitizer.for(:account_update)  |u| u.permit(:username, :email, :password, :password_confirmation, :current_password) 
  end
end

设计.rb

Devise.setup do |config|
  require 'devise/orm/active_record'
  config.case_insensitive_keys = [:email, :username]
  config.authentication_keys = [:login]
  config.strip_whitespace_keys = [:email, :username]
  config.confirmation_keys = [:login]
  config.reset_password_keys = [:login]

end

routes.rb

Rails.application.routes.draw do
  devise_for :users, controllers:  
    registrations: 'users/registrations', sessions: 'users/sessions'
  
...
end

我还编辑了视图以包含用户名字段

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

  <div class="field">
    <%= f.text_field :username, autofocus: true %>
  </div>

我是否遗漏了一些可以让所有其他信息正确保存到数据库但阻止用户名保存的东西？

感谢您的任何帮助

编辑：这是“用户”的架构，表明我确实有用户名。

create_table "users", force: :cascade do |t|
  t.string   "username",               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
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

还有我最近测试的服务器日志：

更多信息：

直接在控制台中运行 User.create 方法时，用户名会正确保存

[1] pry(main)> User.create(username: "test11", email: "[e-mail]", password: "password", password_confirmation: "password")
   (0.3ms)  BEGIN
  User Exists (1.0ms)  SELECT  1 AS one FROM "users" WHERE LOWER("users"."username") = LOWER('test11') LIMIT 1
  User Exists (0.3ms)  SELECT  1 AS one FROM "users" WHERE "users"."email" = $1 LIMIT 1  [["email", "test11"]]
  User Exists (0.4ms)  SELECT  1 AS one FROM "users" WHERE "users"."email" = '[e-mail]' LIMIT 1
  SQL (0.5ms)  INSERT INTO "users" ("username", "email", "encrypted_password", "created_at", "updated_at") VALUES ($1, $2, $3, $4, $5) RETURNING "id"  [["username", "test11"], ["email", "[e-mail]"], ["encrypted_password", "deleted"], ["created_at", "2015-10-05 17:22:11.677278"], ["updated_at", "2015-10-05 17:22:11.677278"]]
   (3.7ms)  COMMIT

 id: 10,
 username: "test11",
 email: "[e-mail]",
 encrypted_password: "deleted",

我的用户控制器用于注册，因为我在该控制器和应用程序控制器中都尝试过参数：

class Users::RegistrationsController < Devise::RegistrationsController
before_filter :configure_sign_up_params, only: [:create]
before_filter :configure_account_update_params, only: [:update]

  # protected

  def configure_sign_up_params
    binding.pry
    devise_parameter_sanitizer.for(:sign_up)  |u| u.permit(:login, :username, :email, :password, :password_confirmation) 
  end

  # If you have extra params to permit, append them to the sanitizer.
  def configure_account_update_params
    devise_parameter_sanitizer.for(:account_update)  |u| u.permit(:login, :username, :email, :password, :password_confirmation, :current_password) 
  end

end

【参考方案1】：

经过大量试验和错误以及其他编码人员的一些建议后，我发现问题是 2 部分。 1 部分是我没有足够频繁地重新启动我的服务器，所以我虽然正在测试的一些更改实际上并没有加载。我的问题的第二部分是，即使我在应用程序控制器中正确设置了强参数，因为我也在我的 registrations_controller.rb 中设置了它们（并且没有完全注释掉），registrations_controller 覆盖了我的其他设置.我没有 :login 作为注册控制器中的参数，并且（即使它在上面列出）由于没有重新启动服务器，上面列出的更改没有注册（参见第 1 部分）.... /facepalm
