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 => "myappname@gmail.com",    :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 abc@mail.ru (3757.4ms) Date: Thu, 21 Nov 2013 01:19:45 +0400 From: metahall.app@egmail.com Reply-To: metahall.app@egmail.com To: abc@mail.ru Message-ID: <528d2771ac762_27b352e85246162c@Active-pc.mail> Subject: Confirmation instructions Mime-Version: 1.0 Content-Type: text/html;  charset=UTF-8 Content-Transfer-Encoding: 7bit  <p>Welcome abc@mail.ru!</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 Completed 302 Found in 4648ms (ActiveRecord: 59.8ms)

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 :)
