Saving Array to Realm in Swift?

Deadly 提交于 2019-12-10 01:59:19
问题 Is it possible to save an array of objects to Realm ? Anytime I make a change to the array it should be saved to Realm. My current solution is to save object for object with a for loop . For append/modifying objects calling save() will do the job, but not when I remove an object from it. class CustomObject: Object { dynamic var name = "" dynamic var id = 0 override static func primaryKey() -> String? { return "id" } } struct RealmDatabase { static var sharedInstance = RealmDatabase() var

Realm Swift2: Best practice for model and Realm model class separation

回眸只為那壹抹淺笑 提交于 2019-12-10 01:47:54
问题 I just have started working with Realm for Swift. After reading the documentation, still I have a couple of question marks in mind. My biggest one is, if there is a best practice for separation Model classes from Realm classes. For example, in Java MVC projects we used DAO classes (Data Access Object classes) which were responsible for the communication with the database layer. Our corresponding model classes only have either the dao object injected or we used service classes for this (like

Design Pattern for Realm Database Swift 3.1 - Singleton

时光总嘲笑我的痴心妄想 提交于 2019-12-10 00:47:48
问题 I'm working on RealmSwift, which is a modern database replacement of CoreData/SQLite in Swift. I'm wondering how to implement a design for a Class which can manage/handle all the queries for RealmSwift Framework This question is somewhat similar to implementing SQLite Model Manager but for RealmSwift. Specifically I don't require a singleton object/instance mention above. 回答1: Realm has a rather clever internal caching system where previous instances of Realm are held onto and recycled each

手摸手教你SSM框架整合Shiro后的开发 前面,我们学习了 Shiro实现权限管理之表结构设计 以及 JQuery-Ztree.js使用范例 ,接下来就详细介绍一下SSM框架整合Shiro框架后的开发。同样推荐大家参看张开涛老师的 跟我学Shiro ,或者可以看我的笔记: Shiro实现授权 、 Shiro实现身份认证 。 如果你对SSM框架的整合不是很熟悉,你或许可以参看我的这个项目 SSM框架整合 。 下面我们就开始实现一个SSM+Shiro的权限管理项目吧! <!--more--> 测试环境 IDEA + Tomcat8 + Maven 起步 初始化数据库,请参考 /db 中的代码 导入依赖 导入Shiro框架需要的依赖: shiro-core-1.3.2.jar shiro-ehcache-1.3.2.jar shiro-quartz-1.3.2.jar shiro-spring-1.3.2.jar shiro-web-1.3.2.jar 其他依赖请参看项目中的 pom.xml 文件 搭建SSM框架 搭建SSM框架的过程这里不再详细说了,可以参看我的 SSM框架整合案例 <br/> SSM框架整合Shiro 环境配置 1.在web.xml中配置Shiro的过滤器 与Spring集成: <filter> <filter-name>shiroFilter</filter

Using Realm with RxJava 2

会有一股神秘感。 提交于 2019-12-09 20:50:29
问题 I am using RxJava 2 in my Android application, and am integrating Realm. As far as I can tell, Realm only supports RxJava 1 by default, and allows an Observable to be returned when querying for RealmResults<?> , like so: Realm.getDefaultInstance() .where(VideoBundle.class) .findAll() .asObservable() .first() The Observable returned is from RxJava 1. How can I use Realm and RxJava 2 together? I have come across 2 relevant issues, found here and here, but no succinct answer was found.

Synchronized Realm - Airplane Mode

好久不见. 提交于 2019-12-09 19:25:43
问题 Can't find anything in the documentation about falling back to the locally cached version of a synchronized realm when eg. the App is started in airplane mode. Am I missing something? 回答1: If the user did log in before (when the connection was available) you can use SyncUser.all() to get a valid authenticated user, but if no user exists a network call to the auth server is required. We are working on adding support for creating a Realm and a User without initial network connection here: https

clang: error: exit code 1 错误详解

自古美人都是妖i 提交于 2019-12-09 18:18:05
!最近一次在"导入Realm数据库,多人SVN协作时候发生错误",因为Relam核心库被墙,导致另一个电脑使用install时候报错;不使用pod手动导入即解决问题 先介绍什么样情况下会出现这个错误 重复添加某个库 某个库从pod管理到手动管理 pod库导入时同时导入framework 文件重复 一些库pod管理时,不同电脑报错 . . . 可以从如下几个方面着手排查 1.多人开发更新代码not found错误 查看错误中提到的类,并且在右侧勾选target ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation) 2.更新完pod编译报错 检查Podfile,确认是否需要"use_frameworks!",如果不需要,去掉重新install platform :ios, '8.0' use_frameworks! target 'MyApp' do pod 'AFNetworking', '~> 2.6' pod 'ORStackView', '~> 3.0' pod 'SwiftyJSON', '~> 2.3' end 3.如果是新添加的第三方库,且不是静态库 找到 Build

shiro的使用

Subject(主体) 通过安全管理器进行 认证 和授权 SecurityMannager 安全管理器 SecurityMannager 是shiro框架的核心 Authenticator 认证器 对主体进行认证 Authorizer 授权器 用户通过认证器认证通过,在访问功能时通过授权器判断用户是否有此功能的操作权限 Realm SecurityMannager 进行安全认证需要通过Realm湖区用户权限数据 Realm 也是一个接口 Realm: 从配置文件或者数据库等读取用户的权限信息 多实现: 1.将用户的权限信息存储到配置文件 2.将用户的权限信息存储到数据库 SessionManager 会话管理器 shiro框架有一套自己的session容器 shiro可以使用到非wevb项目上的,也可以实现单点登录 SessionDao 是对session会话操作的一套接口,比如要将会话信息存储到redis数据库 CacheManager 缓存管理器(提高性能)缓存第三方 防止用户每次或是重复登陆,都需要在数据库获取一次权限信息,所以存放在缓存中 对于用户反复查询访问自身那个权限的这种操作,便提供了缓存管理器 第一次访问后将信息放入缓存管理器,在接下来的操作中,直接从缓存中获取用户权限 Cryptography 密码管理器,shiro提供了一套加密/解密的组件,方便开发

Android's realm.io how to sync with server side MySQL DB

房东的猫 提交于 2019-12-09 12:40:09
问题 I am working on an Android app using realm db as my local db, how do I sync my records in realm with my server side MySQL db? 回答1: Update from 27 Septermber 2016: Realm now fully supports synchronizing data against Realm Object Server. More details are available here. 19 June 2016 There is no such way - the Realm doesn't have such mechanisms, and it is logical. You mix different approaches - syncing data and storing locally (the mission of Realm, SQLite and other Android mobile DBs). You can
