Question

我正在使用Ruby on Rails中的邮件程序运行测试，我收到以下错误：

*********-C02MGBVJFD57:myapp ************$ bundle exec rake test:mailers

# Running:

EE

Finished in 0.110500s, 18.0995 runs/s, 0.0000 assertions/s.

当我检查我的fixtures users.yml文件时，我看到我正在使用时区ruby戳：

michael:
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>
  admin: true
  activated: true
  activated_at: <%= Time.zone.now %>

archer:
  name: Sterling Archer
  email: duchess@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

lana:
  name: Lana Kane
  email: hands@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

mallory:
  name: Mallory Archer
  email: boss@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

<% 30.times do |n| %>
user_<%= n %>:
  name:  <%= "User #{n}" %>
  email: <%= "user-#{n}@example.com" %>
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>
<% end %>

和我的db / seeds.rb文件如下所示：

User.create!(name:  "Example User",
             email: "example@railstutorial.org",
             password:              "foobar",
             password_confirmation: "foobar",
             admin: true,
             activated: true,
             activated_at: Time.zone.now)

99.times do |n|
  name  = Faker::Name.name
  email = "example-#{n+1}@railstutorial.org"
  password = "password"
  User.create!(name:  name,
               email: email,
               password:              password,
               password_confirmation: password,
               activated: true,
               activated_at: Time.zone.now)
end

编辑：这是测试

测试/邮寄者/ user_mailer_test.rb：

require 'test_helper'

class UserMailerTest < ActionMailer::TestCase

  test "account_activation" do
    mail = UserMailer.account_activation
    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

  test "password_reset" do
    mail = UserMailer.password_reset
    assert_equal "Password reset", mail.subject
    assert_equal ["to@example.org"], mail.to
    assert_equal ["from@example.com"], mail.from
    assert_match "Hi", mail.body.encoded
  end
end

我做错了吗？谢谢您的帮助。

Answer 1

您的迁移文件中的activate_at是否为datetime？您可以尝试Time.zone.now.to_datetime。

Answer 2

或者您只需在灯具中使用固定的created_at时间：

created_at: "2015-08-15 20:53:32"

Answer 3

我正在使用MySQL 5.7.10。尝试使用ModelName.connection.execute（SQL语句）将记录直接插入到表中时，我遇到了类似的问题，包括created_at和updated_at时间戳。

这对我有用：

'#{DateTime.now.strftime('%F %T')}'

请务必包含周围的单引号。

Answer 4

我怀疑您的专栏属于＆＃39; datetime＆＃39;。使用＆＃39; DateTime.now.in_time_zone＆＃39;而不是＆＃39; Time.zone.now＆＃39;

Answer 5

我有同样的错误。但我已在 seeds.rb 和 users.yml 中更新datetime部分Timezone.now.to_datetime，然后运行：

$ bundle exec rake db:migrate:reset
$ bundle exec rake db:seed

然后运行

$ bundle exec rake test

你想要得到所有的绿色。

Answer 6

ActiveRecord :: Base.sanitize将采用ruby Time对象并正确转换为带引号的sql值

For i As Integer = 0 To dgvFields.Rows.Count - 1
       If dgvfields.Rows(i).Cells("THE COLUMN NAME").Value="ValueA" Then
          'do something
       End if    
Next

日期时间值不正确; Ruby on Rails
