问题 When I try to customise a tableView cell, I found this error. "Get output frames failed, state 8196" I just have no idea it is the error from realm or from my customise tableView cell. class StudentTableViewController: UITableViewController { let realm = try! Realm() var student: Results<StudentName>? var selectedClass: ClassName? { didSet { load() } } var selected: String = "" override func viewDidLoad() { super.viewDidLoad() navigationController?.title = selected tableView.register

问题 I am experiencing an issue that is pointed out in Realm's documentation: Jackson Databind Jackson Databind is a library for binding JSON data to Java classes. Jackson uses reflection to perform the data binding. This conflicts with Realm’s support for RxJava, as RxJava might not be available to the class loader. This can result in an exception that looks like this: Copy to clipboardjava.lang.NoClassDefFoundError: rx.Observable at libcore.reflect.InternalNames.getClass(InternalNames.java:55) .

问题 I have written a simple test case using for testing Realm db. But I'm always getting error java.lang.UnsatisfiedLinkError: Can't load library: /tmp/android-tmp-robolectric4167396756480823821/app_lib/librealm-jni.so This is my test import org.junit.Test; import org.junit.runner.RunWith; import org.robolectric.RobolectricTestRunner; import org.robolectric.RuntimeEnvironment; import io.realm.Realm; @RunWith(RobolectricTestRunner.class) public class RealmTest { @Test public void realmShouldWork()

问题 I have prepopulated realm database, so I have default.realm. I want to use it in another app so I put it in my \res\raw folder. I read that it should be as easy as calling Realm.getInstance(). I have code like this: copyBundledRealmFile(this.getResources().openRawResource(R.raw.default0), "default.realm"); realm = Realm.getInstance(this); private String copyBundledRealmFile(InputStream inputStream, String outFileName) { try { File file = new File(this.getFilesDir(), outFileName);

问题 Using Swift 4 and Realm 3.0.1, I'd like to store a list of Realm objects in a property of a parent Realm object. I ran into the following problem: In Swift 4, properties that should be persisted into Realm have to be @objc dynamic , e.g. @objc dynamic var id: String = "" . However, Realm's Array replacement type, List , can not be stored that way: @objc dynamic var children: List<Child>? = nil causes this compiler error: Property cannot be marked @objc because its type cannot be represented

问题 Getting unknown key while converting realm model into json object using jackson library. Here is my realm model instance. public class RecordData extends RealmObject { public RecordData() { } private FormData formData; @Nullable @JsonProperty("values") private RealmList<Values> values; @Nullable @JsonProperty("value") private String value; } Code for converting realm model to json object.

问题 I have the following RealmObject: public class City extends RealmObject { private String cityId; private RealmList<Street> streets; public String getId() { return cityId; } public void setCityId(String cityId) { this.cityId = cityId; } public RealmList<Street> getStreets() { return streets; } public void setStreets(RealmList<Street> streets) { this.streets = streets; } } Now having a cityId I need to query streets of particular city. How to do that? What I did try was: Realm.getInstance

问题 I recently installed realm using: npm i realm -S react-native link realm Important edit This issue only occurs when debugging from device Everything still works but this time, when I try to enable Debug Js Remotely from the development menu, I get the error Must first create RPC session with a valid host . Remote debugging used to work and the development server is still running on port 8081 as it used to be. If there is any code example you want, please let me know. Realm is not invoked

I am getting json response and extends RealmObject class as per RealM documents. but still not getting any good way to store my response into realm directly. Dashboard Activity: apiInterface = APIClient.getClient().create(APIInterface.class); final Call<RealmList<ExampleTest>> call = apiInterface.getSurvay(); call.enqueue(new

问题 If I iterate over an array in Swift with: for element in array { ... } and place a breakpoint inside the for statement and look at the address of the object stored as element, than I get a different address than if I let the debugger run the expression: array.first There is only one element in the array. So, why do I not get the same address? Here is a screenshot of the debugger in action: I am iterating over the attachments of a mail. When I debugged, the mail only had one attachment. The
