问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 2 years ago . I'm building an app and I need to use a database in it. I'm considering using Room as it's new and hot right now. But I've heard a lot of great stuff about Realm too. Can someone point out the possible advantages of using each? I did my research and read the docs but I have

How to backup Realm DB in Android before deleting the Realm file. Is there any way to restore the backup file?

由 ≡放荡痞女 提交于 2019-11-29 04:17:17
I am working on an Android application where I will be deleting Realm before copying the new data to Realm. Is there any way I can take backup of the data before deleting it and restore it back if something is wrong when using realm.copyToRealm() ? Realm.writeCopyTo might be helpful for this case. You can find doc here. //Backup Realm orgRealm = Realm.getInstance(orgConfig); orgRealm.writeCopyTo(pathToBackup); orgRealm.close(); //Restore Realm.deleteRealm(orgConfig); Realm backupRealm = Realm.getInstance(backupConfig); backupRealm.writeCopyTo(pathToRestore); backupRealm.close(); orgRealm =

Shiro的几个关键类

由 有些话、适合烂在心里 提交于 2019-11-29 03:32:08
Shiro在于Spring集成中，需要配置SecurityManager，Realm，ShiroFilterFactoryBean这三个类。在Web环境中SecurityManager一般配置DefaultWebSecurityManager，如果需要扩展或者定制一些额外的功能，可以配置DefaultWebSecurityManager的继承类；Realm需要先继承AuthorizingRealm抽象类再配置，如果有多个Realm的话，还需要配置ModularRealmAuthenticator的继承实现类；ShiroFilterFactoryBean主要是提供ShiroFilter，可以配置一些资源的拦截。下面对一些核心类进行一下总结。 SecurityManager 该类继承了三个接口，还额外提供登录，退出和创建用户的功能。 /** * 所有与安全有关的操作都会与SecurityManager交互 * 扩展了authenticator、authorizer和sessionmanager接口 */ public interface SecurityManager extends Authenticator, Authorizer, SessionManager { Subject login(Subject subject, AuthenticationToken

Proper way to get Realm object by its primary key in Android Java

由 坚强是说给别人听的谎言 提交于 2019-11-29 02:54:16
问题 I wonder if there's a proper way to retrieve an object given its primary key in Realm for Android. I know the method objectForPrimaryKey does exists in Swift but there seems to be no such counterpart in Realm for Android. I really think that doing realm.where(EventInfo.class).equalTo("id", eventInfo.id).findFirst(); looks like a lot of waste (at least it is not wrist-friendly). Am I missing some method? I'm Currently using Realm 1.0.1 回答1: This is why I have a Realm repository like this one

Realm and auto increment Behavior (Android)

由 萝らか妹 提交于 2019-11-29 02:26:57
问题 I'm trying to get data from Realm using an ID as a reference. However, when querying for an ID, I've found that Realm is giving me the same ID for all elements (ID of 0). Why doesn't the ID auto-increment when I use the @PrimaryKey annotation on the model's ID? Here's the shortened class for the model: public class Child_pages extends RealmObject { @PrimaryKey private int id_cp; private int id; private String day; private int category_id; And the query I'm executing is: realm.where(Child

This is step is listed in the instructions for installing Realm. link here: https://realm.io/docs/swift/latest/ I am new to xcode and I don't understand how to complete this step.
