小编Sac*_*ngh的帖子

我想设置一个默认日期,实际日期,例如我如何设置它？

<%= date_field_tag(:datetime_ida, value = nil, options = {})%>

另外,我如何在组合框中设置默认值

<%= select_tag :children_quantity, options_for_select([['0 Children', 0], ['1 Children', 1], ['2 Children', 2], ['3 Children', 3], ['4 Children', 4], ['5 Children', 5]], 1) %>

顺便说一句,date_field_tag和date_field之间有什么区别？

我正在使用AWS Cognito的忘记密码API,它的工作正常.但我面临一个问题.我使用手机号码注册,稍后我将电子邮件属性添加到该用户池记录并致电forgot password API它发送手机号码验证码,但我希望它通过电子邮件发送,我该怎么办呢？这是我的代码.

AWS_COGNITO.forgot_password({ client_id: ENV['AWS_WEB_APP_ID'], username: 'valid username'})

根据API文档,#forgot_password仅在哈希值中使用两个值

如果我需要更多信息,请告诉我.谢谢

当我尝试安装时，我不断收到同样的错误

我已经查看了其他几个帖子并尝试了解决方案但没有成功.

问题被标记为此解决方案的副本 无法在ruby上加载此类文件 - sqlite3/sqlite3_native(LoadError) 但是给出的答案对我不起作用.我只是得到了同样的错误

我刚安装了rails,所以一切都是最新的我使用以下内容:Windows 10,ruby版本2.5.1,rails版本5.2.0

我也尝试用bundle update更新SQLite gem.

这是错误:

我经常ActionDispatch::Cookies::CookieOverflow在我的rails应用程序中遇到heroku错误.我认为在会话中倾倒未使用的信息就像

env["airbrake.error_id"] = notify_airbrake(e)

可能有问题.

我已经在会话中抛出了许多字符串,也许这可能是问题所在.我读了一些帖子,暗示这也可能是因为activeadmin.最后我想创建一个会话表的建议在这里

我无法弄清楚解决这个问题的最佳方法是什么？ 请建议所有可能的解决方案

我的config/initializers/session_store.rb中的代码

Demo::Application.config.session_store :cookie_store, key: '_demo_appplication', :domain => :all

通过airbrake我得到这个错误的堆栈跟踪

我使用Amazon S3进行文件上传,使用Cloudfront进行静态资产服务,在我的config/environments/staging.rb中,我写道

ActionController::Base.asset_host = Proc.new { |source|
  if source.include?('/assets')
    "d1xw0c7m8has5k.cloudfront.net"
  else
    "#{ENV['FOG_DIRECTORY']}.s3.amazonaws.com"
  end
}

ActionMailer::Base.asset_host = Proc.new { |source|
  if source.include?('/assets')
    "d1xw0c7m8has5k.cloudfront.net"
  else
    "#{ENV['FOG_DIRECTORY']}.s3.amazonaws.com"
  end
}

但是在我的邮件中,通过rails应用程序发送,我看到image_tag src属性为空？即没有显示图像.这个设置有什么问题我无法识别,请帮助.

我是流星的新手不知道为什么我在控制台中收到此错误.

我正在使用 minitest 测试 ruby​​ 应用程序

我有这样的场景：

class TestExample

   def test_method
      SomeOtherClass.new.print_message "Hello World!!!!!"
   end

end

在这里，我想模拟 的print_message方法SomeOtherClass，并像这样尝试

mock = MiniTest::Mock.new
test_example = TestExample.new
mock.expect(SomeOtherClass.new, nil, ["Hello World!!!!!"])
test_example.test_method
mock.verify

它不起作用，它给出了如下异常： -

MockExpectationError: expected #("Hello World!!!!!!") => [], got []
