我试图使用ruby1.9.1在Ubuntu Natty Narwhal 11.04上安装rails.

我安装了apt-get install ruby1.9.1-full包含dev包的ruby .我用Google搜索了错误,所有人都建议我安装我已经拥有的1.9.1-dev.

Building native extensions.  This could take a while...

这两个字段有什么区别？:

• 每次请求的时间(平均值)
• 每个请求的时间(意味着,跨所有并发请求)

他们每个人的计算方式如何？

样本输出:

Time per request:       3953.446 [ms] (mean)
Time per request:       39.534 [ms] (mean, across all concurrent requests)

为什么会有很大差异？

我在许多项目中发现了这个缩写,它是一个引用活动记录上下文中的数据库模型的文件夹

但它究竟意味着什么？

尝试构建 React Native 项目，但无法编译 appcompat

在 org.gradle.api.internal.artifacts.dsl.dependency.DefaultDependencyHandler 类型的对象上找不到参数 [com.android.support:appcompat-v7:25.0.0] 的方法compile()。

构建.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 21
        compileSdkVersion = 28
        targetSdkVersion = 27
        supportLibVersion = "28.0.0"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        compile 'com.android.support:appcompat-v7:25.0.0'

我有一个接收数组作为参数的测试方法,我想从数据提供程序方法提供数据？

怎么能实现呢？

public function dataProvider(){
        return array(array(
                'id'=>1,
                'description'=>'',
        ));
}

/**
 * @dataProvider dataProvider
 */
public function testAddDocument($data){
// data here shall be an array provided by the data provider
// some test data here
}

会发生什么,它传递'id'键等的值

我想传递整个数组

我想从视图中访问应用程序配置.如何在ZF 2中实现这一目标？

我正在按照本指南设置 trustkit SSL pinning：https : //github.com/datatheorem/TrustKit-Android

我在尝试安装信任工具包依赖项时遇到错误

我的 build.gradle 看起来像这样

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "com.facebook.react:react-native:+"  // From node_modules
    implementation 'com.datatheorem.truskit:trustkit-android:1.1.3'

    if (enableHermes) {
      def hermesPath = "../../node_modules/hermesvm/android/";
      debugImplementation files(hermesPath + "hermes-debug.aar")
      releaseImplementation files(hermesPath + "hermes-release.aar")
    } else {
      implementation jscFlavor
    }
}

错误：

我正在运行带有多进程索引的蜘蛛，我想解决这个问题。

我总是收到 TOO_MANY_REQUESTS，是否可以更改配置以允许更大的阈值来处理并发请求？

这是完整的错误

我只使用一个集合的mongo db并且消耗100%的平均cpu使用率,我如何限制其资源？

注意:我有核心2四核处理器,运行centos

您可以使用实体方法遍历实体,并且您可以使用实体存储库完全相同,不同之处在于您将创建额外的类并将其附加到实体,并且存储库也会对其他开发人员产生某种混淆以了解是否某种方法可用,他们需要检查实体和存储库.

还有其他区别吗？使用自定义存储库有什么好处？或者处理这种情况的最佳做法是什么？

在控制器中,我可以像这样调用viewRenderer帮助器:

$this->_helper->viewRenderer->setNoRender(true);

如何在控制器动作助手中调用viewRenderer？假设我有一个Controller动作助手:

class Zend_Controller_Action_Helper_Ajaxrequest extends Zend_Controller_Action_Helper_Abstract{

   public function test(){
       //what I should do here
   }
}
