升级到13.04完全搞砸了我的系统.我在跑步时遇到这个问题

     ./manage.py runserver

我正在尝试在EC2上设置Grails Web应用程序

InstanceType:m3 xlarge

从http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html安装了JAVA

版本:java版"1.7.0_80"Java(TM)SE运行时环境(版本1.7.0_80-b15)Java HotSpot(TM)64位服务器VM(版本24.80-b11,混合模式)

(因为JAVA 8存在问题:https://github.com/spring-projects/spring-loaded/issues/98)

从GVMtools安装Grails

http://gvmtool.net/

grails version : 2.4.3

从中安装了mongoDB

http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/

与版本MongoDB shell版本:3.0.2连接到:test

我的DataSource.groovy配置是:

environments {
    development {
        grails {
            mongo {
                host = "localhost"
                port = 27017
                username = "root"
                password = "root"
                databaseName = "someDatabase"
            }
        }
        dataSource {
            dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
        } 
    }

我的Buildconfig.groovy有最新的mongo插件:

compile ":mongodb:3.0.3"

但启动服务器后

grails run-app

并打开我得到的任何页面

我已成功将数据表与bootstrap合并(感谢datatable的优秀文档!).我现在想使用bootstrap的glyphicons作为输入搜索字段.要做到这一点,我需要放置一个图标<i class="icon-search"></i>.有没有一种简单的方法来实现这一目标？

我尝试过的事情是:

$(document).ready(function() {
  $('#table').dataTable( {
    sDom: '<"icon-search"r><"H"lf>t<"F"ip>',
    oLanguage: {sSearch: ""},
    "bPaginate": false,
    "bLengthChange": false,
    "bFilter": true,
    "bSort": false,
    "bInfo": false,
    "bAutoWidth": false } );
} );

但这会将图标放在输入字段内.

我想将输入字段包装为:

<div class="control-group">
<label class="control-label" for="inputIcon">Search : </label>
  <div class="controls">
   <div class="input-prepend">
   <span class="add-on"><i class="icon-envelope"></i></span>
   <input class="span2" id="inputIcon" type="text">
  </div>
 </div>
</div>

我在检测管道流结束时遇到问题。脚步：

1. 读取文件
2. 创建 gzip
3. 写文件

这是检测管道流读写结束的正确方法。

var inp = fs.createReadStream(fileName);
var out = fs.createWriteStream(fileName + '.gz');
var gzip = zlib.createGzip();
inp.pipe(gzip).pipe(out);
out.on('finish', function () { ....

对比

var inp = fs.createReadStream(fileName);
var out = fs.createWriteStream(fileName + '.gz');
var gzip = zlib.createGzip();
var zipStream = inp.pipe(gzip).pipe(out);
zipStream.on('finish', function () { ....

我有两个div我想通过onclick事件有条件地展示它们.

我的棱角,app.js

$(document).on('click', '#showless', function(el) {
 var appElement = document.querySelector('[ng-app=myapp]');
 var $scope = angular.element(appElement).scope();
  $scope.$apply(function() {
      $scope.value = false;
    });

});

$(document).on('click', '#showmore', function(el) {
  var appElement = document.querySelector('[ng-app=myapp]');
  var $scope = angular.element(appElement).scope();
  $scope.$apply(function() {
       $scope.value = true;
 });

});

和myapp的my div(myapp.html)

    <div ng-show="desc" id="description" class="text-muted" style="padding-top:5px;padding-left:10px;padding-right:10px;color:#2E2E2E;font-size:11px;">{{myapp.value|truncate}}<span><a id="showmore" href="">more</a></span>
    </div>
    <div ng-show="!desc" id="description" class="text-muted" style="padding-top:5px;padding-left:10px;padding-right:10px;color:#2E2E2E;font-size:11px;">{{myapp.value}}<span><a id="showless" href="">less</a></span>
    </div>

(truncate是我编写的过滤器,工作正常.)
