由 淺唱寂寞╮ 提交于 2020-01-06 19:29:06
问题 I'm using realm to store a list of Products in my Andorid App. So, I receive a produtc's list with about 3k objects. And I'm trying to store them like this: @Override public void saveAll(List<ProductsDomain> domainProducts) throws InstantiationException, IllegalAccessException { Realm instance = getRealmInstance(); RealmList<ProdutcsRealm> realmProducts = new RealmList<ProdutcsRealm>(); try { ProdutcsRealm realmProduct = getClasseEntidadePersistencia().newInstance(); for (ProductsDomain

Delete model from Realm

由 女生的网名这么多〃 提交于 2020-01-06 19:28:36
问题 I am trying to remove a model from Realm. I appears there's a straightforward way to do it in Java with realm.getSchema().remove(className) It doesn't appear there is an option in Swift 3 other than to remove the model from the App and then migrate the data, or delete the entire Realm file. To clarify, when I open the Realm Browser I have three models Dog 2 Person 4 Test 0 and I want to remove just the Test model via code. There doesn't appear to be any way to remove it via the Browser either

问题 I had a Route object and I saw that I can't serialize it. So I said I'll debug and try to serialize the objects from it, separately. This is my function: public JSONObject getRouteJson(Next_Step step) { JSONObject route = new JSONObject(); try { ObjectMapper mapper = new ObjectMapper(); mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false); RouteNonRealm r = new RouteNonRealm(step.getRoute()); String string = mapper.writeValueAsString(r.getDuration()); route.put("duration", string

Save an object in NSUserDefaults and Realm

由 点点圈 提交于 2020-01-06 07:19:14
问题 Is it possible to save an object in both NSUserDefaults and Realm (Swift) ? I have found a problem in creating my Model since NSUserDefaults require the inheritance of NSObject and Realm requires the inheritance of Object . Doing so , raised this error Multiple inheritance from classes 'Object' and 'NSObject' 回答1: Using Swift4's Codable protocol, you can save a custom class to UserDefaults without having to conform to the old NSCoding protocol. class Team: Object, Codable { @objc dynamic var

Why can't I get the index of a filtered realm List?

问题 I'm trying to find the index of an item in a List<> object after the item has been appended to it, so that I can insert into a tableview. The tableview is sectioned with .filter s so I have to apply the filter before looking for the indexPath. However, the filter appears to break the indexOf functionality. I noticed that the function .map has the same effect. import UIKit import RealmSwift class Model: Object { @objc dynamic var title: String = "" let items = List<Model>() } class

Realm sample code from the docs gives 'io.realm.exceptions.RealmException: Dog is not part of the schema for this Realm'

问题 I'm trying to adapt for Kotlin a very simple piece of Java Realm code straight from the docs: // Define your model class by extending RealmObject class Dog : RealmObject() { var name: String? = null var age: Int = 0 } class Person : RealmObject() { @PrimaryKey val id: Long = 0 val name: String? = null val dogs: RealmList<Dog>? = null // Declare one-to-many relationships } In onCreate : // Initialize Realm (just once per application) Realm.init(this); val config: RealmConfiguration =

Can I only call Realm.getInstance() once in Application?

由 痞子三分冷 提交于 2020-01-06 04:21:06
问题 I am toying with Realm and I always find that Realm.getInstance() is called during Activity create and instance closed in Activity destroy. May I know is there any side impact that keep only one instance create and open all the time until the application is closed? 回答1: There is no Application onDestroy. Realm does the necessary caching internally, so it should be safe to call Realm.getInstance()/close() as many times as you want. Trying to do your own caching will not make anything more

上一篇文章已经对shiro框架做了一定的介绍，这篇文章讲述使用spring整合shiro框架，实现用户认证已经权限控制 1.搭建环境 这里不在赘述spring环境的搭建，可以简单的搭建一个ssm框架，整合后进行简单的测试 1.1 添加依赖 <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.3.2</version> </dependency> <!--shiro核心包--> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.3.2</version> </dependency> 1.2 web.xml配置 在web.xml中添加如下过滤器，注意filter-name的值是shiroFilter <!-- Shiro Security filter filter-name这个名字的值将来还会在spring中用到--> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter
