Computed property as in predicates, and as sortProperty in RealmSearchViewController?

由 [亡魂溺海] 提交于 2019-12-07 08:22:07
问题 I have a realm object Song with dynamic var title = "" . I've written a computed property, sortedName that sorts out any pesky prefixes like "The " or parentheses and punctuation. I want my RealmSearchViewController to use sortedName as its sortProperty but this is throwing the error: "Property 'sortedName' not found in object of type 'Song'" I get the same error when using sortedName in predicates (such as if results.objects(with: NSPredicate(format: "sortedName BEGINSWITH %@", key)).count >

问题 I have a custom polygon object so I can save map overlays to Realm. I'm able to create this objects successfully, but when I want to retrieve the var polygon object it returns nil.

Proper way to abstract Realm in Android apps

由 扶醉桌前 提交于 2019-12-07 04:45:11
问题 I'm trying out Realm.io in an Android app, though, to stay on the safe side, I would like to abstract the DB layer so that, in case of need, I can switch back to a standard SQLite based DB without rewriting most of the app. I'm however finding it difficult to properly abstract Realm due to it's particular nature: When tied to a realm, RealmObjects are proxies so I cannot pass them around as they were POJOs. All Realm instances need to be properly opened and closed for every thread they are

Writing and reading between threads with Android Realm

问题 I'm performing some investigation of Realm threading and encountered issue. In this simple example I have 2 Thread objects, one for writing and second one for reading. The reader Thread gets count of written objects always as 0, but inside writer scope the size() for items in DB is correct. When I relaunch app, the reader gets the first count ok before any insertions. Thread writer = new Thread() { @Override public void run() { while (mRunning) { try { Realm r = Realm.getInstance(context,

Why is it recommended practice to store images on disk rather than in a Realm

由 為{幸葍}努か 提交于 2019-12-07 03:13:25
问题 I am using Realm as the database solution for my app. I need persistent storage ability for my images so I can load them when offline. I also need a cache so I can load the images from there rather than fetching them from the API each time a cell draws them. My first thought was that a Realm database could serve both of these functions just fine if I were to store the images in Realm as NSData. But I have found two answers on SE (here and here) that recommend not doing this if you have many
