仍然没有找到正确的方法,而是想出了适合我需求的工作(黑客)。
使用 oneDitformPreloadtext 代码> malakhere '),编辑了'标题
'变更标题的参数,然后使用新页名重定向。在挂钩函数中,如果找到(仅是重定向的原因),则需要检查“ malakhere
”参数,然后它将退出该函数,以免创建循环。
public static function onEditFormPreloadText(string &$text, Title &$title ) {
global $wgOut;
if ( isset( $_GET["MalakHere"] ) ) {
return true;
}
$pos = strpos($text, "[[Category:Malak]]");
if ($pos) {
$url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
$urlTitle = urlencode($_GET["title"]);
$newURL = str_replace("title=" . $urlTitle,"MalakHere=yes",$url);
$newTitle = self::newTitlePre() . $title->prefixedText;
$url = $newURL . "&title=" . $newTitle;
return $wgOut->redirect($url);
}
return true;
}

然后使用这些方法进行序列化和挑选化。
“获取”,“ set”,“ is”被消除,这些方法中仍然存在的内容将用作JSON字段。
因此,您的“ is_something”将其更改为“ _something”等等。
主题标签是uris的保留字符(表示片段)。
保留= gen-delims / sub-delims gen-delims =“:” /“ /” /“?” /“#” /“ [“ /”]“ /”@” sub-delims =“!” /“ $” /“&amp;” /“'” /“(“ /”)” /“*” /“+” /“,” /“;” /“ =”
而且,重要的是:
如果URI组件的数据将与保留角色作为定界符的目的相抵触,则在形成URI之前,必须对矛盾的数据进行分配。

看起来不像是正确格式化的JWT,它的3个片段分别为时期。
您需要使用一个领域SDK或Admin API获取客户端访问令牌。
我认为所有其他领域客户端SDK都应该具有 user.accesstoken
conscotor方法。
以及有关如何使用Admin API获取访问令牌的更多一般文档 - https://www.mongodb.com/docs/atlas/atlas/app-services/reference/reference/reference/authenticate/authenticate-http-client-reqlient-request-requests/#std -label-authenticate-http-client-requests
另外,如果您使用的是自定义JWT auth,请求标题不同。从文档中:
http.post({
"url": "https://realm.mongodb.com/api/client/v2.0/app/<yourappid-abcde>/graphql",
"headers": {
"jwtTokenString": "<User's JWT Token>"
},
"body": '{"query":"query AllMovies {\n movies {\n title\n year\n }\n}"}'
})
在自定义JWT请求标头上进行进一步阅读 - https://www.mongodb.com/docs/atlas/app-services/graphql/authenticate/#custom-jwt
您正在运行原始查询,因此将转换为 date
实例而不是Postgres驱动程序的不是Typeorm。
我不确定是否可以配置驱动程序不执行转换,但是相对简单的解决方法可能是将与时间相关的字段强加于字符串:
SELECT date::text AS dateString, dueDate::text AS dueDateString, * FROM invoice
从文档 :
>>> import datetime
>>> from django.db.models import Q, Avg
>>> from django.db.models import F
>>> apr21 = Avg('aqi', filter=Q(date__range=(datetime.date(2021, 4, 1), datetime.date(2021, 4, 30)))
>>> apr22 = Avg('aqi', filter=Q(date__range=(datetime.date(2022, 4, 1), datetime.date(2022, 4, 30)))
>>> aqi_calc = Airquality.objects.annotate(apr21=apr21)
.annotate(apr22=apr22)
.annotate(diff=F('apr22') - F('apr21'))
如果我没记错的话,应该在1查询中完成所有操作。
如果要将其概括为更长或更多的列表/数组,则可以查看numpy:
a1 = np.array([True, True, False])
a2 = np.array([False, False, True, False])
out = np.r_[a1, ~a2]
output: array([真,true,true,false,true,true,true,true,false,true])

这应该给您一些想法。假设我们使用的是一个名为 testdb
的测试数据库,并且您的原始表被命名为 test
,它具有3列IE a
, b ,<代码> c
。桌子上的三行就像您之前提供的一样。接下来,我们可以继续创建一个存储过程。注意:使用准备好的语句以获取每列的总和值的背后原因是由于必须进行硬编码的规则,该规则无法用变量替换。例如从test;
中选择“ sum(a)”,无法将其写入从test;
中选择sum(@column_name)。通过使用准备好的语句,我们可以动态编码列名。
delimiter //
drop procedure if exists table_sum//
create procedure table_sum (db_name varchar(20),tb_name varchar(20))
begin
declare col_name varchar(10);
declare fin bool default false;
declare c cursor for select column_name from information_schema.columns where table_schema=db_name and table_name=tb_name;
declare continue handler for not found set fin=true;
drop temporary table if exists result_tb;
create temporary table result_tb (`Columns` varchar(10),`Values` varchar(25));
open c;
lp:loop
fetch c into col_name;
if fin=true then
leave lp;
end if;
set @stmt=concat('select sum(',col_name,') into @sum from test ;');
prepare stmt from @stmt;
execute stmt;
deallocate prepare stmt;
set @val=concat('sum(',col_name,') = ',@sum);
insert result_tb values(col_name,@val);
end loop lp;
close c;
select * from result_tb;
end//
delimiter ;
最后,我们调用该过程以获取所需的输出:
call table_sum('testdb','test');
标签解决问题后添加一个空格:
Window {
width: 640;
height: 480;
visible: true;
title: qsTr("Code from @Meliodas on StackOverflow");
TextArea {
id: textArea;
textFormat: Qt.RichText;
focus: true;
selectByMouse: true;
selectByKeyboard: true;
Keys.onPressed: (event) => {
if (event.text === "@") {
// HERE
insert(cursorPosition, "<a href='mentioned://user'>@User</a> ");
event.accepted = true;
}
}
}
}
请注意,我享有修改其他代码的自由:
- 警告告诉我隐式
事件
参数已弃用
- 只需将应用程序类的静态实例存储在您想要的地方 - &gt;不是理想的解决方案,但它起作用* source> source
打开class myapplication:application:application( ){
override fun onCreate() {
super.onCreate()
instance = this
}
companion object {
lateinit var instance: MyApplication
private set
fun getApplicationContext(): Context? {
return instance.applicationContext
}
}
}
这样使用:
MyApplication.instance.cacheDir()
*您将在组件之间引入直接依赖性
您项目的应用程序类,使得无法使用这些
具有另一个应用程序类的组件,无法声明
例如,这些组件在单独的Gradle模块中。 - link
- 使用di,例如使用hilt-&gt;到小型项目的开销?
- 自定义Kotlin Singleton实施 - &gt;可读性和复杂性缺点。
如果您不需要在field weft_links_10g上进行DB查询,我可以使用@property:

将其加速,例如:但是,如果您想执行一些DB操作(例如filter或order_by) :
if you don't need to do db query on field leave_links_10g i sugest use @property:
you can acces it like normal field e.g.:
but if you want to do some db operations like filter or order_by you need to override save method of model KT:
