我知道%USERPROFILE%Windows XP(以及Vista和Windows 7)上的系统定义环境变量.是否有系统定义的环境变量指向"我的文档"目录的位置？默认情况下在XP上%USERPROFILE%\My Documents,在Win 7上它是%USERPROFILE%\Documents.我只是想避免在Powershell脚本中测试操作系统版本,如果我可以避免它.
我尝试使用Glassfish 3.1和Postgres为Web应用程序创建登录页面.我有本地数据库(localhost:5432).这是我的连接池:
Pool Name:pacjentauth
Resource Type:javax.sql.DataSource
Datasource Classname:org.postgresql.ds.PGSimpleDataSource
Driver Classname: [nothing here]
portNumber,ServerName,用户和密码都可以.这是我得到的错误:

我在 magento 后端创建了网格，但分页不起作用。无论我选择每页有多少条记录，页面上总是可以看到所有记录。现在我在数据库中有 41 条记录，并且网格上方的“统计信息”正常（找到的页数和记录数）：
Page 1 of 3 pages | View 20 per page | Total 41 records found
哪个文件负责分页？按特定列排序还有另一个问题。例如。记录的显示方式与我按 ID 选择 ASC 或 DESC 顺序相同...
网格：
public function __construct() {
parent::__construct();
$this->setId('logger_grid');
$this->setUseAjax(FALSE);
$this->setDefaultSort('id');
$this->setDefaultDir(Varien_Data_Collection::SORT_ORDER_ASC);
$this->setSaveParametersInSession(TRUE);
}
public function _prepareCollection() {
$collection = Mage::getModel('logger/logger')->getCollection()->load();
$this->setCollection($collection);
return parent::_prepareCollection();
}
public function _prepareColumns() {
$this->addColumn('id', array(
'header' => Mage::helper('logger')->__('ID'),
'sortable' => TRUE,
'index' => 'log_id',
'editable' => FALSE,
));
$this->addColumn('interface', array(
'header' => Mage::helper('logger')->__('Interface'),
'sortable' => TRUE,
'index' => 'interface', …在你减去这个问题之前,你应该知道我搜索了解决方案而没有找到它.
我想通过rest端点返回String:
@GET
@Path("/getMyString")
@Produces({ MediaType.APPLICATION_JSON })
public Response getId() {
String s = "this is my string";
(...)
return Response.ok(s).build();
}
但是在视图中我收到了char数组(结果是firebug):
Resource { 0="t", 1="h", 2="i", more...}
在前面我使用角度资源,如:
blablaResources.factory('AngularApp', [ '$resource', function($resource) {
return $resource(contextPath + '/.rest/v1/someService', {}, {
(... other methods ...)
getString : {
method : 'GET',
url : contextPath + '/.rest/v1/someService/getMyString'
}
});
} ]);
是否有任何String或注释的包装类来发送它:
Resource { value = "this is my string" }
或者只是正常
"this is my string"
感谢任何建设性的回应:)
我有一个像
http://api.mycompany.com/products/bycategory/{category_id}
结尾部分/products/bycategory/{category_id}是如何命名的？例如，如果我删除域部分，如果我将它放在 web.config 中，我如何命名其余部分？
URI？我看了一些文章，但我很困惑。有时完整的 Url 似乎是 URI 其他提到的剩余部分。
谢谢。
我阅读了magnolia文档,但我仍然不确定如何为现有页面创建新区域.我想要做的是上面的横幅区域(带图像和一些文字)<div id="wrapper-2">.我正在使用Magnolia CE 4.5.9.
我应该做的可能是:
1)添加新区域:[templating-kit选项卡]/templates/prototype/areas
2)添加一行[@cms.area name="banner" content=content/]到/templating-kit/pages/main [模板试剂盒/模板]标签
3)[配置]选项卡中的内容(？)
在此先感谢您的帮助.
我在Magento中制作了我的模块,但它需要为所有产品分配额外的属性.我制作了安装脚本,但它不起作用:
<?php
$installer = $this;
$installer->startSetup();
$installer->run("
INSERT IGNORE INTO `{$installer->getTable('eav/attribute')}` (`attribute_id`, `entity_type_id`, `attribute_code`, `attribute_model`, `backend_model`, `backend_type`, `backend_table`, `frontend_model`, `frontend_input`, `frontend_label`, `frontend_class`, `source_model`, `is_required`, `is_user_defined`, `default_value`, `is_unique`, `note`) VALUES
SELECT 1 + coalesce((SELECT max(attribute_id) FROM `{$installer->getTable('eav/attribute')}`),0),4,`is_accepted`,NULL,NULL,`int`,NULL,NULL,`boolean`,`Accepted`,NULL,`eav/entity_attribute_source_boolean`,1,1,'0',0,NULL);
");
$installer->endSetup();
Config.xml文件:
<adminhtml>
<acl>
<module_setup>
<setup>
<module>My_module</module>

这有什么不对？
我正在做一个代码来查找列表的长度,使用递归,但是有很多错误.我是一个非常初学者,我不能很好地Haskell.这是代码:
longListe :: [a] -> a
longListe [] = error "Empty liste"
longListe [x]= 1
longListe n = 1 + longListe (n-1)
main = print $ longListe
和错误:
No instance for (Num a) arising from the literal ‘1’
Possible fix:
add (Num a) to the context of
the type signature for longListe :: [a] -> a
In the expression: 1
In an equation for ‘longListe’: longListe [x] = 1
4-1-a.hs:6:31:
No instance for (Num [a]) arising from a use of …我需要促销/优惠券按顺序改变哪个项目的信息以及折扣前这个项目的价格和这个项目的最终价格.我知道,这很复杂所以这是一个例子:
<order>
<items>
<item> <!-- This item have discount in order -->
<sku>1234</sku>
<promotion>
<promo_id>456</promo_id>
<discount_value>10</discount_value><!-- In % or $ -->
</promotion>
<final_price>25</final_price>
</item>
<item><!-- This item don't have discount in order -->
<sku>1234</sku>
<promotion/>
<final_price>35</final_price>
</item>
</items>
</order>
我希望这是可以理解的解释.谢谢你的帮助.
编辑:我忘了一件事.所有我都有来自销售/订单模型的信息.这是一个接口,所以我无法访问会话数据,我从数据库获得验证的订单.
