Question

我正在我的Rails 4应用程序中运行一些测试，我收到以下错误：

1) Error:
UsersLoginTest#test_valid_signup_information:
NoMethodError: undefined method `deliver_now' for #<Mail::Message:0x000001058258b0>
    app/controllers/users_controller.rb:33:in `create'
    test/integration/users_login_test.rb:33:in `block (2 levels) in <class:UsersLoginTest>'
    test/integration/users_login_test.rb:32:in `block in <class:UsersLoginTest>'


  2) Error:
UsersSignupTest#test_valid_signup_information:
NoMethodError: undefined method `deliver_now' for #<Mail::Message:0x0000010b8fa7a8>
    app/controllers/users_controller.rb:33:in `create'
    test/integration/users_signup_test.rb:21:in `block (2 levels) in <class:UsersSignupTest>'
    test/integration/users_signup_test.rb:20:in `block in <class:UsersSignupTest>'

他们都说过：未定义的方法`deliver_now＆＃39;

我不确定为什么会这样。

app / controllers / users_controller.rb：33 - ＆gt;

def create
    @user = User.new(user_params)
    if @user.save
      UserMailer.account_activation(@user).deliver_now
      flash[:info] = "Please check your email to activate your account."
      redirect_to root_url
    else
      render 'new'
    end
  end

test / integration / users_login_test.rb:21 - ＆gt;

test "valid signup information" do
    get signup_path
    assert_difference 'User.count', 1 do
      post_via_redirect users_path, user: { name:  "Example User",
                                            email: "user@example.com",
                                            password:              "password",
                                            password_confirmation: "password" }
    end
    assert_template 'users/show'
    assert is_logged_in?
  end

你看到了这个问题吗？

Answer 1

尝试：

  UserMailer.account_activation(@user).deliver! # or .deliver

Answer 2

deliver_now已在rails 4.2.x中引入它不适用于rails 4.1.0

接下来，我们更新到rails 4.2.0（注意：不要以这种方式更新Rails - 简单的方法 - 在生产中！）：

omega@UbuntuSvr14:~/railsprjs/sample_app$ vi Gemfile
omega@UbuntuSvr14:~/railsprjs/sample_app$ head Gemfile
source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
