publish

I have a question about how to just get a certain element of an array using MongoDB and MeteorJS. I have the following schema for the user document: bankList:[ { id: "34567890987654345678", name: "xfgchjbkn", type: "credit" }, { id: "09876543456789098767" name: "65789876t8", type: "debit" } ] I first subscribe to only part of the fields in the array, specifically I gather a list of all the ids. Then I have an edit screen that should subscribe to all of the fields for a specific element in the array with a matching id. I do not want to expose the rest of the array just the single element.

orm语句 -- sql -- 调用pymysql客户端发送sql -- mysql服务端接收到指令并执行 增: 方式1: new_obj = models.UserInfo( id=2, name='小猿1', bday='2019-09-27', checked=1, ) new_obj.save() 方式2: # ret 是创建的新的记录的model对象(重点) ret = models.UserInfo.objects.create( name='小猿2', bday='2019-08-07', checked=0 ) # objects相当于一个控制器，它可以控制这个类给这个类一些操作方法，比如增删改查等 print(ret) #UserInfo object ret是实例化对象 print(ret.name) # 获取当前实例化对象的name值 print(ret.bday) 时间问题 models.UserInfo.objects.create( name='大猿2', bday=current_date, # now=current_date, 直接插入时间没有时区问题 checked=0 ) #但是如果让这个字段自动来插入时间,就会有时区的问题,auto_now_add创建记录时自动添加当前创建记录时的时间,存在时区问题 now = models

1.ORM简介 MVC或者MVC框架中包括一个重要的部分，就是ORM，它实现了数据模型与数据库的解耦，即数据模型的设计不需要依赖于特定的数据库，通过简单的配置就可以轻松更换数据库，这极大的减轻了开发人员的工作量，不需要面对因数据库变更而导致的无效劳动 ORM是“ 对象-关系-映射 ”的简称。 类对象--->sql--->pymysql--->mysql服务端--->磁盘，orm其实就是将类对象的语法翻译成sql语句的一个引擎 2.字段,类型 常用字段 AutoField 自增的整形字段，必填参数primary_key=True，则成为数据库的主键。无该字段时，django自动创建。 一个model不能有两个AutoField字段。 IntegerField 一个整数类型。数值的范围是 -2147483648 ~ 2147483647。 CharField 字符类型，必须提供max_length参数。max_length表示字符的长度。 DateField 日期类型，日期格式为YYYY-MM-DD，相当于Python中的datetime.date的实例。 参数： auto_now：每次修改时修改为当前日期时间。 auto_now_add：新创建对象时自动添加当前日期时间。 auto_now和auto_now_add和default参数是互斥的，不能同时设置。

I am facing a problem that when I publish my ClickOnce application through MSBuild (4.0), the publish.htm (or default.htm) isn't created in the app.publish folder. When publishing through Visual Studio, it gets crated... In my .csproj file I have the following properties set, and it still not working... <CreateWebPageOnPublish>true</CreateWebPageOnPublish> <WebPage>default.htm</WebPage> Any ideas? Thanks I found a good solution here . You can use a template for publish.htm with {VERSION} placeholder inside. MSBuild Community Tasks are required for the FileUpdate task. BUILD_VERSION -

I have some test apps that I never intend to publish to the official Play store (aka Android Market), via this website . I need to remove them and use new ones instead, as I've also forgotten where I've put the signing key of the test apps. So, how do I remove the old test apps from the account? I just can't understand why they have this strict behavior. They said that if the key is not found, the app becomes an orphan. Why couldn't they just check in the server if the app was deleted and notify the user that the app won't get any updates, and give him an alternative for the app via the same
