问题 I have been looking over to many ORM's in android, by far what i have used and would fit to my app so far are ActiveAndroid and SugarOrm, but what i need is not currently supported(not supported but can be fix by creating sql scripts) as of now (one-to-many relationship). Im looking at Realm ORM for android a very promising one. Is this possible with Realm? // this is just a sample of what i need to do., // parent class Message{ long id; List<Meta> messages; } // child class Meta{ long

问题 I'm using Realm and Parceler and everything is working fine but when I enable the Proguard I'm getting an error when doing: Parcels.wrap(obj) I'm getting the following error: org.parceler.ParcelerRuntimeException: Unable to find generated Parcelable class for io.realm.g, verify that your class is configured properly and that the Parcelable class io.realm.g$$Parcelable is generated by Parceler. Although I have configured the proguard rules like: ##---------------Begin: proguard configuration

问题 Firstly, i defined the TestSchema first, and create "let realm = new Realm({schema: [TestSchema]})",and the result for {realm.objects('Test').length} is right. When i try to add more schemas into realm, e.g.'let realm = new Realm({schema:[TestSchema, CarSchema, PersonSchema]})', it shows the wrong msg. "Object Type Car is not found in schema". I was wondering what's going on here. 回答1: Put all these schema definitions in one file, say realm.js, and export these schemas. You can check this.

问题 My problem is this: When i open dialog fragment, i send realm and realm results from activity to dialog fragment. I always send different realm results to dialog fragment, depending what i click in activity. This is code in dialog fragment where i receive realm and realmResults from activity, when i click to open dialog fragment: public void setChangeNoteListener(ChangeNoteListener mChangeNoteListener, RealmResults<Drop> realmResults, Realm realm) { mNotelistener = mChangeNoteListener;

问题 I've encountered following error when I've complied following code: *** Terminating app due to uncaught exception 'RLMException', reason: 'Attempting to modify object outside of a write transaction - call beginWriteTransaction on an RLMRealm instance first.' for outlet in brand.outlets! { let outl = OutletListRealm() outl.outletId = outlet.id outl.outletName = outlet.name! outl.brand = brand.id try! self.realm.write { self.realm.add(outl) } for override in outlet.override! { let overRide =

问题 I have a list with 4 objects of places that I query from my Realm database. Optional(Results<Place> <0x7feaaea447c0> ( [0] Place { name = Daniel Webster Highway; country = United States; lat = 42.72073329999999; lon = -71.44301460000001; }, [1] Place { name = District Avenue; country = United States; lat = 42.48354969999999; lon = -71.2102486; }, [2] Place { name = Gorham Street; country = United States; lat = 42.62137479999999; lon = -71.30538779999999; }, [3] Place { name = Route de HHF;

问题 I have an object that subclasses Object from Realm, and conforms to Codable in order to convert to and from JSON when talking to an API. How can I make a deep copy (include children objects) by leveraging the Codable protocol? 回答1: This will make a deep copy of an object leveraging the Codable protocol. As mentioned by @itai-ferber it will have a high overhead when compared to NSCopying . class MyObject: Object, Codable { /* details omitted */ var children = List<ChildObject>() func copy()

问题 I have an application where I need to keep the data in the same order as it is entered. The data is entered into a List property. Everything works great until I have to delete an item. When the delete occurs the last item on the List takes the place of the one that was deleted. The UITableView shows the correct number of items but is not synchronized with the realm List. An example would be if I had data: 1, 2, 3, 4, 5, 6 I then delete: 3 The realm data looks like this: 1, 2, 6, 4, 5 The

问题 I am relatively new in this field, and really stuck here as how to get the current schemaVersion of realm. I tried Below code to check my schemaVersion let configCheck = Realm.Configuration(); let configCheck2 = Realm.Configuration.defaultConfiguration; let schemaVersion = configCheck.schemaVersion print("Schema version \(schemaVersion) and configCheck2 \(configCheck2.schemaVersion)") but Output was coming zero always Schema version 0 and configCheck2 0 But I have already changed my
