如何在 Devise 中启用 :confirmable? [英] How do I enable :confirmable in Devise?

问题描述

Devise 的最新版本默认没有启用 :confirmable.我已经将相应的列添加到用户模型中，但找不到任何关于如何启用 :confirmable 的代码示例.

The newest version of Devise doesn't have :confirmable enabled by default. I already added the respective columns to the User model but cannot find any code examples of how to enable :confirmable.

在哪里可以找到好的示例或启用它需要什么代码?

Where can I find a good example or what code do I need to enable it?

推荐答案

要启用"可确认，您只需要将其添加到您的模型中，例如:

to "enable" confirmable, you just need to add it to your model, e.g.:

class User
  # ...
  devise :confirmable , ....
  # ...
end

之后，您必须创建并运行迁移，将所需的列添加到您的模型中:

after that, you'll have to create and run a migration which adds the required columns to your model:

# rails g migration add_confirmable_to_devise
class AddConfirmableToDevise < ActiveRecord::Migration
  def self.up
    add_column :users, :confirmation_token, :string
    add_column :users, :confirmed_at,       :datetime
    add_column :users, :confirmation_sent_at , :datetime
    add_column :users, :unconfirmed_email, :string

    add_index  :users, :confirmation_token, :unique => true
  end
  def self.down
    remove_index  :users, :confirmation_token

    remove_column :users, :unconfirmed_email
    remove_column :users, :confirmation_sent_at
    remove_column :users, :confirmed_at
    remove_column :users, :confirmation_token
  end
end

我建议检查源代码以了解 Confirmable 的工作原理:

I'd recommend to check the source code to see how Confirmable works:

https://github.com/plataformatec/devise/blob/master/lib/devise/models/confirmable.rb

您还可以在 Devise 上查看 RailsCast:

You could also check the RailsCast on Devise:

接下来最好在 GitHub 上搜索示例应用程序

Next it would be best to search for example applications on GitHub
