有人可以通过Michael Harty的测试10.20 Ruby on Rails教程吗？我有下面的错误，我无法理解;除了我完全遵循教程指导。

对于前。教程说改为noreply@example.com"] 但它指向这条线的错误...... 我是否应该更改此行并告知Michael Harty有关错误/做其他事情来修复错误？

我添加了将Michael更改为Tatyana的文件，但仍然出现以下错误：我找到此文件并将其添加到更改michael到tatyana但仍然出现如下错误：错误[＆＃34; test_account_activation＆＃34;，UserMailerTest，2016-03-23 16:43:44 +0000] test_account_activation＃UserMailerTest（1458751424.20s） ActionView :: Template :: Error：ActionView :: Template :: Error：缺少要链接的主机！请提供：host参数，设置default_url_options [：host]，或将：only_path设置为true app / views / user_mailer / account_activation.html.erb：9：_app_views_user_mailer_account_activation_html_erb__2380038393264600902_67365800' app/mailers/user_mailer.rb:5:in account_activation＆＃39; test / mailers / user_mailer_test.rb:9:in block in <class:UserMailerTest>' app/views/user_mailer/account_activation.html.erb:9:in _ app_views_user_mailer_account_activation_html_erb__2380038393264600902_67365800＆＃39; app / mailers / user_mailer.rb：5：account_activation' test/mailers/user_mailer_test.rb:9:in块中＆＃39;

Answer 1

UserMailer.account_activation 方法在测试中需要用户参数。

class UserMailerTest < ActionMailer::TestCase

  test "account_activation" do
    mail = UserMailer.account_activation(User.create(email: "foo@bar.com"))
    assert_equal "Account activation", mail.subject
    assert_equal ["to@example.org"], mail.to
    assert_equal ["from@example.com"], mail.from
    assert_match "Hi", mail.body.encoded
  end
end

Answer 2

该错误来自user_mailer_test.rb:6第6行。

在class UserMailer第3行，您将user对象传递给def account_activation(user)，但在UserMailer.account_activation中没有传递任何内容。继续关注那本书应该是这样的例子。

user = users(:michael)
user.activation_token = User.new_token
mail = UserMailer.account_activation(user) # right here user passed.

Answer 3

test / mailers / user_mailer_test.rb如下所示，可以摆脱一个错误：

要求'test_helper'

类UserMailerTest＆lt;的ActionMailer ::测试用例

测试“account_activation”做

user = users(:tatyana)

user.activation_token = User.new_token

mail = UserMailer.account_activation(user)

assert_equal "Account activation", mail.subject

assert_equal [user.email], mail.to

assert_equal ["noreply@example.com"], mail.from

assert_match user.name,               mail.body.encoded

assert_match user.activation_token,   mail.body.encoded

assert_match CGI::escape(user.email), mail.body.encoded

端

还有另外一个如下：错误[“test_account_activation”，UserMailerTest，2016-03-23 16:43:47 +0000] test_account_activation＃UserMailerTest（1458751427.01s） ActionView :: Template :: Error：ActionView :: Template :: Error：缺少要链接的主机！请提供：host参数，设置default_url_options [：host]，或将：only_path设置为true app / views / user_mailer / account_activation.html.erb：9：_app_views_user_mailer_account_activation_html_erb__1635017718511086794_82209820' app/mailers/user_mailer.rb:5:in account_activation' test / mailers / user_mailer_test.rb:9:in block in <class:UserMailerTest>' app/views/user_mailer/account_activation.html.erb:9:in _ app_views_user_mailer_account_activation_html_erb__1635017718511086794_82209820' app / mailers / user_mailer.rb：5：在{<1}}块中的'
