Rails 4 with MailCatcher and Devise gems

问题:

I have an app with gem Devise. I need to confirm registration by email. In config/environment.rb I added this

ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
   :address => "smtp.gmail.com",
   :port => 587,
   :domain => "gmail.com",
   :authentication => 'plain',
   :user_name => "[e-mail]",
   :password => "mypassword"
}

In config/environment/development.rb added:

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = { :address => "127.0.0.1", :port => 1025 }

I want to catch all email by gem MailCatcher But when i submit to send confirmation instructions nothing happens in mailcatcher gem. But in console i have something like that:

Sent mail to [e-mail] (3757.4ms)

<p>Welcome [e-mail]!</p>

<p>You can confirm your account email through the link below:</p>

<p><a href="http://localhost:3000/users/confirmation?confirmation_token=hnrgdXgv4nARwiAzaXFy">Confirm my account</a></p>

Redirected to http://localhost:3000/users/sign_in

And have NOTHING in mailcathcer. What's wrong?

This is happening to me too. I followed these awnser How do I set up email confirmation with Devise?. Turn out that I forgot to uncomment the confirmation_token foreign key in the devise migration. After that, I drop and recreate the database and worked fine!

So, when you generate the devise model, it's create the following migration, with the respective scope.

class DeviseCreateUsers < ActiveRecord::Migration
  def change
    create_table(:users) do |t|
      ## Database authenticatable
      t.string :email,              null: false, default: ""
      t.string :encrypted_password, null: false, default: ""

      ## Recoverable
      t.string   :reset_password_token
      t.datetime :reset_password_sent_at

      ## Rememberable
      t.datetime :remember_created_at

      ## Trackable
      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

      ## Confirmable
      # t.string   :confirmation_token
      # t.datetime :confirmed_at
      # t.datetime :confirmation_sent_at
      # t.string   :unconfirmed_email # Only if using reconfirmable

      ## Lockable
      # t.integer  :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts
      # t.string   :unlock_token # Only if unlock strategy is :email or :both
      # t.datetime :locked_at


      t.timestamps null: false
    end

    add_index :users, :email,                unique: true
    add_index :users, :reset_password_token, unique: true
    # add_index :users, :confirmation_token,   unique: true
    # add_index :users, :unlock_token,         unique: true
  end
end

To active the confirmation feature, you have to uncomment the following blocks:

 ## Confirmable
 t.string   :confirmation_token
 t.datetime :confirmed_at
 t.datetime :confirmation_sent_at
 t.string   :unconfirmed_email # Only if using reconfirmable

and

add_index :users, :confirmation_token,   unique: true

This should make e-mails appears in MailCatcher.

Best luck :)
