小编Adr*_*der的帖子

我正在尝试使用number_field方法接受小数值(USD,因此12.24就是一个例子).

<div class="controls">
  <%= f.number_field :amount, :class => 'text_field' %>
</div>

这只允许我输入整数值.

我有以下代码:

import lombok.Builder;
import lombok.Getter;

@Getter
@Builder
public class NameParserResponse {
    private boolean match;
}


public class Main {

    public static void main(String[] args) {
        NameParserResponse nameParserResponse = NameParserResponse.builder().build();
        nameParserResponse.isMatch();
    }
}

在尝试引用isMatch()时,我得到:

Ambiguous method call. Both

isMatch () in Response and
isMatch () in Response match

我也尝试删除@Builder注释,但这没有帮助.

我正在尝试为我的bill_total帮助方法创建一个测试.let方法不生成bill1和bill2变量.

describe BillsHelper do
  let(:bill1) { Bill.create(name: 'Bill 1', amount: 1.00) }
  let(:bill2) { Bill.create(name: 'Bill 2', amount: 1.00) }

  describe "#bill_total" do
    bill1.amount = 1.00
    bill2.amount = 1.00

    expect(bills_helper.bill_total).to eq(2.00)
  end
end

错误:

我有一个使用Preloader初始化的Java应用程序.Preloader隐藏后,主应用程序启动并成功加载资源.然后,应用程序窗口会暂时加载然后退出,不会抛出任何异常.

@font-face {
  font-family: "HelveticaNeueLTStd-Lt";
  src: url('/css/fonts/HelveticaNeueLTStd-Lt.otf') format('opentype');
}

这是我的指南针代码的输出:

@include font-face('HelveticaNeueLTStd-Lt', font-files('HelveticaNeueLTStd-Lt.otf'));

我似乎无法让输出网址只是'Helvetica ...... otf'或只是'fonts/Helvetica ...... otf'.

我的目录资产如下:

http_path = "/"
css_dir = "css"
sass_dir = "sass"
images_dir = "img"
javascripts_dir = "js"
fonts_dir = "fonts"

我试过脱掉fonts_dir并将其改为""而没有运气

按照此处概述的命令，我无法在运行raspbian buster的Raspberry PI 4上安装docker。

以下是我依次尝试的命令：

1） apt-get update

2） apt-get install apt-transport-https ca-certificates software-properties-common

3）

add-apt-repository \
       "deb https://apt.dockerproject.org/repo/ \
       raspbian-$(lsb_release -cs) \
       main"

运行以上命令后，我尝试运行apt-get update：

paintComponent(Graphics)添加自定义JComponent时为什么不调用？

public class Test {

    public static void main(String[] args) {
        JFrame frame = new JFrame("Paint Component Example");

        frame.setPreferredSize(new Dimension(750, 750));
        frame.setLocationByPlatform(true);

        JPanel panel = new JPanel();

        panel.add(new CustomComponent());
        frame.add(panel, BorderLayout.CENTER);

        frame.pack();
        frame.setVisible(true);
    }
}

public class CustomComponent extends JComponent {

    public CustomComponent() {
        super();
    }

    @Override
    protected void paintComponent(Graphics g) {
        g.setColor(Color.BLACK);
        g.fillRect(10, 10, 10, 10);
    }
}

我知道在这个实例中没有理由创建自定义组件,但它是我无法弄清楚的另一个问题的极其简化的版本.

我禁用/删除了GOCD go-agent. 看来我无法再尝试注册它go-agent，因为它没有出现在服务启动时的代理列表中。

该代理被删除后是否已被列入黑名单？只是尝试禁用/删除另一个工作正常的 go-agent，它也不再出现在服务启动时的列表中。

我检查了cruise-config.xml，没有提到删除的代理。UI 也不显示已删除的代理。

在遵循有关在批处理脚本中遍历数组的教程时，我没有得到相同的结果：

setlocal enabledelayedexpansion

set topic[3] = Decision making 
set topic[4] = Time and date 
set topic[5] = Operators 

for /l %%n in (0,1,5) do ( 
   echo !topic[%%n]!

当我运行此命令时，我得到：
