Testing for equality in Realm

由 与世无争的帅哥 提交于 2019-12-17 16:49:29
问题 I'm trying to test for equality among Realm objects in unit tests. However, I'm unable to get objects to return true for their equality. According to the Realm docs here, I should be able to do that: let expectedUser = User() expectedUser.email = "help@realm.io" XCTAssertEqual(testRealm.objects(User.self).first!, expectedUser, "User was not properly updated from server.") However, I get the following test failure with the following code: Realm Model class Blurb: Object { dynamic var text = ""

Realm 【Realm】及【Authorizer】部分都已经详细介绍过 Realm 了，接下来再来看一下一般真实环境下的 Realm 如何实现。 1、定义实体及关系 即用户 - 角色之间是多对多关系，角色 - 权限之间是多对多关系；且用户和权限之间通过角色建立关系；在系统中验证时通过权限验证，角色只是权限集合，即所谓的显示角色；其实权限应该对应到资源（如菜单、URL、页面按钮、Java 方法等）中，即应该将权限字符串存储到资源实体中，但是目前为了简单化，直接提取一个权限表，【综合示例】部分会使用完整的表结构。 用户实体包括：编号 (id)、用户名 (username)、密码 (password)、盐 (salt)、是否锁定 (locked)；是否锁定用于封禁用户使用，其实最好使用 Enum 字段存储，可以实现更复杂的用户状态实现。 角色实体包括：、编号 (id)、角色标识符（role）、描述（description）、是否可用（available）；其中角色标识符用于在程序中进行隐式角色判断的，描述用于以后再前台界面显示的、是否可用表示角色当前是否激活。 权限实体包括：编号（id）、权限标识符（permission）、描述（description）、是否可用（available）；含义和角色实体类似不再阐述。 另外还有两个关系实体：用户 - 角色实体（用户编号、角色编号

Upgrade realm in an Android project

问题 I'm currently running Realm Version 0.82.0 in one of my Android projects. I didn't touch Realm for quite some time, until I recently noticed that they went up until version 2.0.2 in the meantime. I would like to upgrade my version of Realm, unfortunately, I don't know if the upgrade from my old version to the current release will be working or breaking my code. I'm especially concerned of migrations, since the API for migrations seemed to have changed a bit since my code, and I'm unsure if my

SpringBoot(十四)：springboot整合shiro-登录认证和权限管理

原文出处： 纯洁的微笑 这篇文章我们来学习如何使用Spring Boot集成Apache Shiro。安全应该是互联网公司的一道生命线，几乎任何的公司都会涉及到这方面的需求。在Java领域一般有Spring Security、Apache Shiro等安全框架，但是由于Spring Security过于庞大和复杂，大多数公司会选择Apache Shiro来使用，这篇文章会先介绍一下Apache Shiro，在结合Spring Boot给出使用案例。 Apache Shiro What is Apache Shiro? Apache Shiro是一个功能强大、灵活的，开源的安全框架。它可以干净利落地处理身份验证、授权、企业会话管理和加密。 Apache Shiro的首要目标是易于使用和理解。安全通常很复杂，甚至让人感到很痛苦，但是Shiro却不是这样子的。一个好的安全框架应该屏蔽复杂性，向外暴露简单、直观的API，来简化开发人员实现应用程序安全所花费的时间和精力。 Shiro能做什么呢？ 验证用户身份 用户访问权限控制，比如：1、判断用户是否分配了一定的安全角色。2、判断用户是否被授予完成某个操作的权限 在非 web 或 EJB 容器的环境下可以任意使用Session API 可以响应认证、访问控制，或者 Session 生命周期中发生的事件

题记 ：在学习了springboot和thymeleaf之后，想完成一个项目练练手，于是使用springboot+mybatis和thymeleaf完成一个博客系统，在完成的过程中出现的一些问题，将这些问题记录下来，作为自己的学习心得。在这先感谢群主TyCoding的Tumo项目，虽然本人实在太菜了，好些地方看不懂，但还是使我受益匪浅。 shiro作为一个小巧灵活的安全框架，在认证和授权方面简约但又不简单，十分容易上手使用。下面是整合shiro的具体流程。 1.添加依赖 1 <!--shiro和spring整合--> 2 <dependency> 3 <groupId>org.apache.shiro</groupId> 4 <artifactId>shiro-spring</artifactId> 5 <version>1.3.2</version> 6 </dependency> 7 <!--shiro核心包--> 8 <dependency> 9 <groupId>org.apache.shiro</groupId> 10 <artifactId>shiro-core</artifactId> 11 <version>1.3.2</version> 12 </dependency> 2.在springboot控制台中添加基础包的扫描和实体类的扫描注解 由于本人实在粗心

问题 I'm looking into migrating our current app to realm and trying to figure out what's the best way to organize the data into ream. For this question I'll focus on the Photo object of my data model (but there're others). All my data objects arrive from an API with endpoints such as: getPopular() , getNearbyPhotos(lat, lng) , getUserPhotos(userId) , getAlbumPhotos(albumId) , getCollection(type) . On most of those endpoints there're further parameters such as sort=best/chronological . We're
