so I'm new to realm data base and I'm trying to show the data that the user wrote throw an Edit text and show it in a Textview..
My realm class
import io.realm.RealmObject
import io.realm.annotations.PrimaryKey
import io.realm.annotations.RealmClass
#RealmClass
open class GoodStudents : RealmObject(){
#PrimaryKey
var id: Long = 0
var name : String? = null
var grade : Int? = null
}
Main activity code
Realm.init(this)
val convig = RealmConfiguration.Builder()
.name("GoodStudents").build()
val realm = Realm.getInstance(convig)
realm.beginTransaction()
count = realm.where(GoodStudents::class.java).findAll().size
val goodStudents = realm.createObject(GoodStudents::class.java, count+1)
goodStudents.name = name.text.toString()
goodStudents.grade
realm.commitTransaction()
val readData = realm.where(GoodStudents::class.java).findAll()
saveButton.setOnClickListener {
Toast.makeText(this,"Data is saved", Toast.LENGTH_LONG).show()
var text = text.text
readData.forEach { save ->
save.name = text as String?
}
}
P.C. Java code is acceptable..
so I found out that writing this code will work
saveButton.setOnClickListener {
val convig = RealmConfiguration.Builder()
.name("GoodStudents").build()
val realm = Realm.getInstance(convig)
realm.beginTransaction()
count = realm.where(GoodStudents::class.java).findAll().size
val goodStudents = realm.createObject(GoodStudents::class.java, count+1)
goodStudents.name = name.text.toString()
goodStudents.grade = grade.text.toString().toInt()
val readData = realm.where(GoodStudents::class.java).findAll()
readData.forEach { save ->
text.text = "" + save.name + ": " + goodStudents.grade
}
realm.commitTransaction()
}

I tried to convert a java file to kotlin file but i'm getting this error : An annotation argument must be a compile-time constant
#StringDef(
BillingEnum.ALL,
BillingEnum.PAID,
BillingEnum.PENDING,
BillingEnum.OVERDUE,
BillingEnum.OPEN,
BillingEnum.DELETED
)
annotation class BillingEnum {
companion object {
var ALL = ""
var PAID = "paid"
var PENDING = "pending"
var OVERDUE = "overdue"
var OPEN = "open"
var DELETED = "deleted"
}
}
Before it looked like this:
#StringDef({
BillingEnum.ALL,
BillingEnum.PAID,
BillingEnum.PENDING,
BillingEnum.OVERDUE,
BillingEnum.OPEN,
BillingEnum.DELETED
})
public #interface BillingEnum {
String ALL = "";
String PAID = "paid";
String PENDING = "pending";
String OVERDUE = "overdue";
String OPEN = "open";
String DELETED = "deleted";
}
You must write
annotation class BillingEnum {
companion object {
const val ALL = ""
const val PAID = "paid"
const val PENDING = "pending"
const val OVERDUE = "overdue"
const val OPEN = "open"
const val DELETED = "deleted"
}
}
I know that sounds weird.
So in my MainActivity am declaring an Array of the object SongInfo which looks like this:
class SongInfo {
lateinit var title: String
lateinit var contentId: String
lateinit var filepath: String
}
This is how I am declaring the Array in my MainActivity:
lateinit var songInfo: Array<SongInfo?>
So, now when I press a button, the listener of this button executes this:
searchButton.setOnClickListener {
val cursor = contentResolver.query(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
arrayOf(
"_id",
"_data",
MediaStore.Audio.Media.TITLE,
MediaStore.Audio.Media.ARTIST,
MediaStore.Audio.Media.DURATION
),
"is_music == 1",
null, null
)
songInfo = arrayOfNulls(cursor!!.count)
for (index in songInfo.indices) {
songInfo[index] = SongInfo()
Log.d(tag, "searchButton: $index")
}
adapter = listMusicService.listMusic(cursor)
adapter.notifyDataSetChanged()
}
The ListMusicService class looks like this:
class ListMusicService(val context: Context, private var adapter: ArrayAdapter<Any>) {
private val tag = "MusicShare/ListMusicService"
fun listMusic(cursor: Cursor): ArrayAdapter<Any> {
val activity = MainActivity()
adapter.clear()
val songInfo = arrayOfNulls<SongInfo>(cursor.count)
var duration: Double
var index = 0
while (cursor.moveToNext()) {
duration = ((cursor.getDouble(4) / 600).roundToInt() / 100).toDouble()
adapter.add(cursor.getString(3) + ": " + cursor.getString(2) + " (" + duration + ")")
val filepath = File(cursor.getString(1))
Log.d(tag, "searchMusic: writing songInfo")
songInfo[index] = SongInfo()
songInfo[index]!!.title = filepath.name
songInfo[index]!!.filepath = filepath.absolutePath
activity.songInfo[index]!!.filepath = filepath.absolutePath
songInfo[index]!!.contentId = cursor.getString(0)
index++
}
return adapter
}
}
Pressing the searchButton now causes a kotlin.UninitializedPropertyAccessException: lateinit property songInfo has not been initialized.
But I don't understand why because in the listener method of searchButton I'm initializing every object of the array. Does anybody know why this happens and maybe what goes wrong?
EDIT: Creating the ListMusicService:
val listMusicService = ListMusicService(this, adapter)
You are creating a new object of MainActivity
val activity = MainActivity()
which is just an empty object, instead you need to pass this as an instance of MainAcitiy to listMusic method and use it.
ListMusicService class already taking a context object so seems like you are passing the activity's instance (no code about it), use the existing adapter instance of MainAcitivty.
// somewhere in main activity
val listMusicService = ListMusicService(this, adapter)
// inside searchButton.setOnClickListener
adapter = listMusicService.listMusic(cursor)
adapter.notifyDataSetChanged()
In ListMusicService
fun listMusic(cursor: Cursor): ArrayAdapter<Any> {
adapter.clear()
val songInfo = arrayOfNulls<SongInfo>(cursor.count)
var duration: Double
var index = 0
while (cursor.moveToNext()) {
duration = ((cursor.getDouble(4) / 600).roundToInt() / 100).toDouble()
adapter.add(cursor.getString(3) + ": " + cursor.getString(2) + " (" + duration + ")")
val filepath = File(cursor.getString(1))
Log.d(tag, "searchMusic: writing songInfo")
songInfo[index] = SongInfo()
songInfo[index]!!.title = filepath.name
songInfo[index]!!.filepath = filepath.absolutePath
activity.songInfo[index]!!.filepath = filepath.absolutePath
songInfo[index]!!.contentId = cursor.getString(0)
index++
}
return adapter
}
Hello guys I have a simple question ,
I have a Map full of element and I want to convert It in my Object , let me show you some code :
Here is my Object :
class Bundle(map: Map<String, Any>) {
var version: String?
var app: String?
var countries: ArrayList<Any>?
var currency: ArrayList<Any>?
var force: Boolean?
var name: String?
var service: ArrayList<Any>?
var money: Int?
init {
version= null
app= null
countries= arrayListOf()
currency= arrayListOf<Any>()
force= true
name = ""
service= arrayListOf<Any>()
money= 0
}
}
And there is the Map that i want to convert:
fun getBundle() {
var db = FirebaseFirestore.getInstance()
val docRef = db.collection("aa").document("bb")
docRef.get().addOnCompleteListener { task ->
if (task.isSuccessful) {
val document = task.result
if (document.exists()) {
Log.d("Doc", "DocumentSnapshot data: " + document.data!!)
// Here i want to take (document.data!!) and convert it to my Bundle class
} else {
Log.d("NO doc", "No such document")
}
} else {
Log.d("ERROR", "get failed with ", task.exception)
}
}
}
Thank you !
Ok I found the solution
I transformed my Bundle class in a data class :
data class Bundle(
var version: String? = null,
var app: String? = null,
var countries: ArrayList<Any> = arrayListOf(),
var currency: HashMap<String, Any> = hashMapOf(),
var force: Boolean = false,
var name: String? = null,
var service: ArrayList<Any> = arrayListOf(),
var money: Int = 0
)
And then I simply added this on my method , where I want to convert my Map to my Bundle Object :
val myObject = document.toObject(Bundle::class.java)
Is it possible to fail my request?
I would like to put Status = KO in asLongAs() section. My condition is like, if I get WorkflowFailed = True or Count > 8 then I want to fail that request using Status = KO.
I have seen somewhere about session.markAsFailed but how and where to use this?
Thanks.
Here is the code,
class LaunchResources extends Simulation {
val scenarioRepeatCount = Integer.getInteger("scenarioRepeatCount", 1).toInt
val userCount = Integer.getInteger("userCount", 1).toInt
val UUID = System.getProperty("UUID", "24d0e03")
val username = System.getProperty("username", "p1")
val password = System.getProperty("password", "P12")
val testServerUrl = System.getProperty("testServerUrl", "https://someurl.net")
val count = new java.util.concurrent.atomic.AtomicInteger(0)
val httpProtocol = http
.baseURL(testServerUrl)
.basicAuth(username, password)
.connection("""keep-alive""")
.contentTypeHeader("""application/vnd+json""")
val headers_0 = Map(
"""Cache-Control""" -> """no-cache""",
"""Origin""" -> """chrome-extension://fdmmgasdw1dojojpjoooidkmcomcm""")
val scn = scenario("LaunchAction")
.repeat (scenarioRepeatCount) {
exec(http("LaunchAResources")
.post( """/api/actions""")
.headers(headers_0)
.body(StringBody(s"""{"UUID": "$UUID", "stringVariables" : {"externalFilePath" : "/Test.mp4"}}"""))
.check(jsonPath("$.id").saveAs("WorkflowID")))
.exec(http("SaveWorkflowStatus")
.get("""/api/actions/{$WorkflowID}""")
.headers(headers_0)
.check(jsonPath("$.status").saveAs("WorkflowStatus")))
}
.asLongAs(session => session.attributes("WorkflowStatus") != "false" && count.getAndIncrement() < 8) {
doIf(session => session("WorkflowFailed").validate[String].map(WorkflowFailed => !WorkflowFailed.contains("true")).recover(true))
{
pause(pauseTime)
.exec(http("SaveWorkflowStatus")
.get("""/api/actions/${WorkflowID}""")
.headers(headers_0)
.check(jsonPath("$.running").saveAs("WorkflowStatus"))
.check(jsonPath("$.failed").saveAs("WorkflowFailed")))
.exec(session => {
val wflowStatus1 = session.get("WorkflowStatus").asOption[String]
val wflowFailed1 = session.get("WorkflowFailed").asOption[String]
println("Inner Loop Workflow Status: ========>>>>>>>> " + wflowStatus1.getOrElse("COULD NOT FIND STATUS"))
println("Inner Loop Workflow Failed?? ========>>>>>>>> " + wflowFailed1.getOrElse("COULD NOT FIND STATUS"))
println("Count =====>> " + count)
session})
}
}
setUp(scn.inject(atOnceUsers(userCount))).protocols(httpProtocol)
}
there's a method available on the session
exec(session => session.markAsFailed)
I stuck with Unit test in Scala for many days. I cannot inject mock object to Unit test. The ScalatraFlatSpec call to the actual database not my mock variable and i have no idea to do.
This is my API
class Dashboard extends Servlet {
get("/:brand_code") {
val start = System.currentTimeMillis
val brandCode = params.get("brand_code").get
var brandId = 0;
val sqlFind = "SELECT DISTINCT(id) FROM brands WHERE brand_code=?"
val found:List[Map[String, Any]] = ConnectionModel.getExecuteQuery(sqlFind, List(brandCode))
if(found.isEmpty){
halt(404, send("error", s"brand_code [$brandCode] not found."))
}else{
brandId = found(0).getOrElse("id", 0).toString.toInt
send("Yeah55", brandId)
}
}
And this is Servlet
abstract class Servlet extends ScalatraServlet with CorsSupport with JacksonJsonSupport {
protected implicit lazy val jsonFormats: Formats = DefaultFormats.withBigDecimal
protected override def transformResponseBody(body: JValue): JValue = body.underscoreKeys
protected lazy val body = parsedBody.extract[Map[String, Any]]
protected def send(message: String, data: Any = None) = Map("message" -> message, "data" -> data)
options("/*") {
response.setHeader(
"Access-Control-Allow-Headers", request.getHeader("Access-Control-Request-Headers")
)
}
before() {
contentType = formats("json")
}
}
And this is ConnectionModel and ConnectionModelAble
trait ConnectionModelAble {
def getExecuteQuery(sql: String, parameters: List[Any]): List[Map[String, Any]]
}
object ConnectionModel extends ConnectionModelAble{
var connection:Connection = {
val url = "jdbc:mysql://localhost:3306/db"
val username = "root"
val password = ""\
Class.forName("com.mysql.jdbc.Driver")
DriverManager.getConnection(url, username, password)
}
def getExecuteQuery(sql: String, parameters: List[Any]): List[Map[String, Any]]= {
try {
val statement = connection.createStatement()
var preparedStatement: PreparedStatement = connection.prepareStatement(sql);
var formatDate: DateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
// Do some execute
for (i <- 0 until parameters.size) {
parameters(i) match {
case _: Int => preparedStatement.setInt(i + 1, parameters(i).toString.toInt)
case _: Double => preparedStatement.setDouble(i + 1, parameters(i).toString.toDouble)
case _: Date => preparedStatement.setDate(i + 1, new java.sql.Date(formatDate.parse(parameters(i).toString).getTime))
case default => preparedStatement.setString(i + 1, parameters(i).toString)
}
}
val resultSet = preparedStatement.executeQuery()
val metaData: ResultSetMetaData = resultSet.getMetaData();
val columnCount = metaData.getColumnCount();
var ret: List[Map[String, Any]] = List();
while (resultSet.next()) {
var row: Map[String, Any] = Map[String, Any]();
for (i <- 1 to columnCount) {
val columnName = metaData.getColumnName(i);
var obj = resultSet.getObject(i);
row += columnName -> obj
}
ret = ret :+ row
}
ret
}catch {
case e: Exception => {
e.printStackTrace();
List()
}
}
}
And this is my unit test
class DashboardSpec extends ScalatraFlatSpec with MockitoSugar {
addServlet(new Dashboard, "/v1/dashboard/*")
it should "return get dashboard correctly" in {
val brandCode = "APAAA"
val brandId = 157
get("/v1/dashboard/APAAA") {
val connectModel = mock[ConnectionModelAble]
val sqlFind = "SELECT DISTINCT(id) FROM brands WHERE brand_code=?"
Mockito.when(connectModel.getExecuteQuery(sqlFind, List(brandCode))).thenReturn(
List(Map("id" -> 150))
)
assert(status == 200)
println(connectModel.getExecuteQuery(sqlFind, List(brandCode)))
println(body)
}
}
}
I found that body from unit test is not from my mock data, it's from real database. What should i do.
Thank you.
You aren't injecting your mock into the Dashboard, so the Connection you're seeing in getExecuteQuery is the one provided by ConnectionModel.connection. You probably want to use a dependency injection framework or something like the Cake pattern to make sure your Dashboard is referring to your mock instance.
