设计：用替代方式替换“电子邮件”以登录 [英] Devise: Replace 'email' with alternative for sign in

问题描述

我试图在整个应用程序中使用Sublime的所有文件替换功能中的电子邮件替换 accountnumber 。

I tried to replace email with accountnumber throughout my whole application using Sublime's "replace in all files" feature.

我重置并重新迁移了数据库，但是，注册时仍然会收到以下错误：

I've reset and re-migrated the DB, however, when registering I still get the following error:

undefined method `email' for #<Account:0x415b690>

然后以下参数

    {"utf8"=>"✓",
 "authenticity_token"=>"2qqA7dx99hx+VqkZGDmySNJd+2Fzxuanegy1ysrpD30=",
 "account"=>{"accountnumber"=>"1307",
 "password"=>"[FILTERED]",
 "password_confirmation"=>"[FILTERED]"},
 "commit"=>"Sign up"}

有没有人有这个困难？

推荐答案

使用Devise，惯例是使用email进行登录，您正在使用gem（Devise），所以并不是所有的代码都可见在您的项目中，替换accountnumber用于电子邮件的搜索替换是不够的。您必须通过更改您的帐户模型来重新配置Devise。

With Devise, the convention is to use 'email' for sign in. You're using a gem (Devise), so not all the code is visible in your project, and a search-and-replace to substitute 'accountnumber' for 'email' is not enough. You have to reconfigure Devise by making changes to your Account model.

请确保在迁移Devise创建的（DeviseCreateUsers）中将电子邮件更改为accountnumber运行 rake db：migrate：reset 。

Be sure to change 'email' to 'accountnumber' in the migration Devise created ('DeviseCreateUsers') and run rake db:migrate:reset.

更改您的帐户模型：

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,  
         :authentication_keys => [:accountnumber]

  def email_required?
    false
  end

  def email_changed?
    false
  end

end

确保您已经在视图文件中生成了Devise视图并将电子邮件更改为accountnumber。

Make sure you've generated Devise views and changed 'email' to 'accountnumber' in the view files.
