我收到以下错误:

java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.testing.models.Account

使用以下代码

final int expectedId = 1;

Test newTest = create();

int expectedResponseCode = Response.SC_OK;

ArrayList<Account> account = given().when().expect().statusCode(expectedResponseCode)
    .get("accounts/" + newTest.id() + "/users")
    .as(ArrayList.class);
assertThat(account.get(0).getId()).isEqualTo(expectedId);

有什么理由不能做到get(0)吗？

你如何在Cake的视图中回显出当前的URL？

我曾经super初始化父类,但我看不到从子类方法调用父类的任何方法.

我知道PHP和其他语言都有这个功能,但是在Ruby中找不到一个很好的方法.

在这种情况下会怎样做？

我在CakePHP中输出XML.但是当我将XML放入验证器时,我遇到了这个错误:

The processing instruction target matching "[xX][mM][lL]" is not allowed.

我<?php echo $this->Xml->header(); ?> 在顶部使用正确的XML布局<?php echo $content_for_layout; ?>

我的结果是:

<?xml version="1.0" encoding="UTF-8" ?><response type='' outcome='true' message='Login successful!'>
    <user id='1234' total_number_of_completed_tasks='0' total_number_of_declined_tasks='0' total_number_of_passed_tasks='1' total_number_of_failed_tasks='1' reputation_points='99' deviant_points='0' />
        <tasks>
            <accepted>
                                <accepted_task id='4' type='Good' time_limit='500' details='Good accepted' />
                                <accepted_task id='5' type='OK' time_limit='660' details='Ok New task' />
                                <accepted_task id='9' type='Excellent' time_limit='2000' details='Great failed task' />
                                <accepted_task id='11' type='Your type' time_limit='222' details='Running and swimming all the way to Japan' />
                                <accepted_task id='7' type='Man' …

有没有办法Rails generate scaffold在控制台中使用命令为列生成has_many关联？

我知道belongs_to是可用的,有用例references但不确定has_many

我想更新git clone上的子模块.

有没有办法用Jenkins管道Git命令做到这一点？

目前我正在这样做......

git branch: 'master',
    credentialsId: 'bitbucket',
    url: 'ssh://bitbucket.org/hello.git'

但是,一旦克隆,它就不会更新子模块

如何使用Rails在一次调用中保存此数组？

tax_rates = [{
  :income_from => 0
  :income_to  => 18200
  :start => "01-07-2013"
  :finish => "30-06-2014"
  :rate => nil
  :premium => nil
  },{
  :income_from => 18201
  :income_to  => 37000
  :start => "01-07-2013"
  :finish => "30-06-2014"
  :rate => 0.19
  :premium => nil
  },{
    :income_from => 18201
    :income_to  => 37000
    :start => "01-07-2013"
    :finish => "30-06-2014"
    :rate => 0.19
    :premium => nil
    }]

我可以打电话Rails.create(tax_rates)吗？

还有,有没有办法删除重复的符号,使它们看起来更整洁？

我有一个代码库,其中一个文件包含很多Structs,Interfaces并且Variables在与函数相同的文件中,我不确定是否需要将其分隔成具有附加文件名的单独文件.因此,例如,accounts.go将accounts_struct.go和accounts_interface.go分别与结构和接口.

当您为Structs,Variables和Interfaces增加代码库时,文件组织的好方法是什么？

我正在努力让pprof与Golang一起工作.

--text似乎工作正常,但大多数其他选项不起作用.

例如使用pdf:

root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --pdf ./src /tmp/profile578584736/cpu.pprof > out.pdf
sh: 1: dot: not found
root@ubuntu:/home/user/IdeaProjects/go_projects/src# 

用gv:

root@ubuntu:/home/user/IdeaProjects/go_projects/src# go tool pprof --gv ./src /tmp/profile578584736/cpu.pprof 
sh: 1: dot: not found
gv -scale 0
Can't exec "gv": No such file or directory at /usr/local/go/pkg/tool/linux_386/pprof line 719.
root@ubuntu:/home/user/IdeaProjects/go_projects/src# 

是否有一些我需要改变的东西去使其工作？

我正在使用附加了Postgres DB Docker容器的Rails.我跑步时看起来好像遇到了以下错误rails c:

/usr/local/rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/uri/generic.rb:204:in `initialize': the scheme postgres does not accept registry part: postgres:@ (or bad hostname?) (URI::InvalidURIError)

有没有理由不这样做？

我database.yml是:

production:
  <<: *default
  url: <%= ENV['DATABASE_URL'] %>

$DATABASE_URL 被定义为

有趣的是,它一直工作到昨天,并且今天又停止了工作.

以下是Rails 4.2.1生成的内容!

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password …
