的ActionMailer爲Appove帳戶 - 電子郵件不發送

Question

我試圖創造出發送當管理員點擊活躍賬戶用戶

用戶HAS_ONE電子郵件：戶名及賬號belongs_to的：用戶

用戶

。 RB

devise :database_authenticatable, :registerable, :Trackable, :rememberable, :recoverable 
attr_accessible :account, :email, :password, :password_confirmation, :account_attributes, :approved 

has_one :account 

end 

在account.rb

class Account < ActiveRecord::Base 

    attr_accessible :address, :approved, :name 
    belongs_to :user 

end 

在accounts_controller.rb

def activate 
    @accounts = Account.find(params[:id]) 
    @users = User.where(:id => @accounts.id) 
    if (@accounts.update_attributes(approved: true)) && (@users.update_all(approved: true)) 
    AccountMailer.activate_account(@users).deliver 
    redirect_to accounts_path 
    else 
    redirect_to accounts_path 
    end 
end 

在account_mailer.rb

class AccountMailer < ActionMailer::Base 
    default :from => "kapanjadi@gmail.com" 

    def activate_account(user) 
    @users = user 
     @account = account.find_by_user_id(user) 
    mail(:to => user.email, :subject => "Activation Account", :from => "kapanjadi@gmail.com") 
    end 
end 

在account_mailer

/activate_account.text.erb

congratulation, your account is active now 

setup_mailer.rb

ActionMailer::Base.smtp_settings = { 
    :address    => "smtp.gmail.com", 
    :port     => 587, 
    :domain    => "localhost:3000", 
    :user_name   => "kapanjadi@gmail.com", 
    :password    => "password", 
    :authentication  => "plain", 
    :enable_starttls_auto => true 
} 

但郵件無法發送電子郵件用戶，並沒有錯誤.. 這些沒有發生任何其他行動。

任何關於我在做什麼的錯誤？

在accounts_controller.rb

def activate 
    @account = Account.find(params[:id]) 
    @user = User.where(:id => @account.id) 
    if (@account.update_attributes(approved: true)) && (@user.update_all(approved: true)) 
    AccountMailer.activate_account(@user,@account).deliver 
    redirect_to accounts_path 
    else 
    redirect_to accounts_path 
    end 
end 

在account_mailer.rb

Answer 1

在accounts_controller.rb

def activate 
    @account = Account.find(params[:id]) 
    @user = User.where(:id => @account.id) 
    if (@account.update_attributes(approved: true)) && (@user.update_all(approved: true)) 


    user_account = account.find_by_user_id(@user) 
    AccountMailer.activate_account(@user,user_account,@account.user.mail).deliver 
    redirect_to accounts_path 
    else 
    redirect_to accounts_path 
    end 
end 

在account_mailer.rb

class AccountMailer < ActionMailer::Base 
    default :from => "kapanjadi@gmail.com" 

    def activate_account(user,account,to) 
    @users = user 
    @account = account 
    mail(:to => to, :subject => "Activation Account", :from=>"kapanjadi@gmail.com") 
    end 
end 

以上將肯定工作。

W¯¯ hy是一切複數（@accounts和@users）？

def activate 
    @account = Account.find(params[:id]) 

    redirect_to accounts_path and return if @account.nil? # handles bad `params[:id]` 

    if @account.update_attributes(approved: true) && @account.user.update_attributes(approved: true) 
    AccountMailer.activate_account(@account.user).deliver 
    redirect_to accounts_path and return 
    end 

    redirect_to accounts_path 
end
