问题 When i click unpublished give error "you have at-least one active .apk " And also cannot update the app because key-store is lost... Any solution? 回答1: Though this is an old post, I thought it might be useful for other developers who are going through the same problem now.

Can I generate a deployment script from a dacpac

邮差的信 提交于 2019-12-23 18:00:04
问题 I've got a .dacpac file that's being called by MSBuild and published to a QA database for testing. This publish is failing and the error I'm getting back from them is a generic "an error has occurred" message. I was hoping I could generate the deployment script from the dacpac and walk through it to see where the problem is occurring and hopefully teach them how to do this as well. Is there any way to point a dacpac at a specific database and have it generate the sql for updating the database

django——模型层之多表操作

django的多表操作 1.使用场景 在实际生产过程多,我们面对的数据纷繁复杂,此时就需要良好的数据结构设计,多表之间的约束关系为我们提供了数据管理以及查询的便利。在MYsql中我们利用外键(foreign key)来实现这样的约束关系,在django中我们通过调用相应的API来实现这样的功能。 2.创建模型 实例:我们来假定下面这些概念,字段和关系 作者模型:一个作者有姓名和年龄。作者详细模型:把作者的详情放到详情表,包含生日,手机号,家庭住址等信息。作者详情模型和作者模型之间是一对一的关系 (one-to-one) 出版商模型:出版商有名称,所在城市以及email。 书籍模型: 书籍有书名和出版日期,一本书可能会有多个作者,一个作者也可以写多本书,所以作者和书籍的关系就是多对多的关联关系 (many-to-many) ; 一本书只应该由一个出版商出版,所以出版商和书籍是一对多关联关系 (one-to-many) 。 模型建立的代码(module)如下: 1 from django.db import models 2 # Create your models here. 3 4 class Author(models.Model): 5 nid = models.AutoField(primary_key=True) 6 name=models.CharField( max
