Assume we have the following function
fun getAnnualData(tenant: String): Flux<DashboardResponse> {
val year = LocalDate.now().year
val annualExpenses = expenseFinder.sumAllByYearAndTenant(year = year, tenant = tenant)
val warehouseExpenses = expenseFinder.sumWarehouseByYearAndTenant(year = year, tenant = tenant)
val annualRevenues = revenueFinder.sumAllByYearAndTenant(year = year, tenant = tenant)
return annualExpenses.zipWith(annualRevenues)
.filter { it.t1._id?.year == year }
.filter { it.t2._id?.year == year }
.map {
DashboardResponse(
period = Period.ANNUAL,
expenses = it.t1,
revenue = it.t2
)
}
}
and I want to add the warehouseExpenses to the returning value. How would I do that?
Where
annualExpenses = Flux
warehouseExpenses = Mono
annualRevenue = Flux
You can simply use a flatMap to combine Mono:
Flux.just(...).zipWith(Flux.just(...))
.filter(...)
.flatMap(tuple -> Mono.just(true).map(m -> new DashboardResponse(tuple.getT1(), tuple.getT2(), m)));

I'm currently working on a Spring Boot Webapp where I want to retreive tasks with JPA.
A Task can have multiple requirements and my customer creates requirement_answers which are connected to his wedding. I now want to select all tasks where all the requirement.answer_value are answered with 'true'.
My relevant Database Schema is:
My current query is this:
I now want to check that the task with the same uuid has all requirement_answer with true?
How can I achieve this?
Greetings
EDIT:
My Solution, filtered in Code instead of jpql as I could not get it working
#Query("""
select t, ra
from
Task t,
RequirementAnswer ra,
Requirement r,
Wedding w
where
ra.requirement = r and
w.id = :weddingId and
t member of r.tasks"
""")
fun findByWedding(weddingId: Long): List<Tuple>?
}
Here is the filtering:
fun getTasksByWedding(wedding: Wedding?): List<Task> {
val tasks: MutableMap<Task,String> = mutableMapOf()
wedding?.id?.let { taskRepository.findByWedding(it) } ?.map {
val task = it.get(0) as Task
val requirementAnswer = it.get(1) as RequirementAnswer
tasks[task]?.let { taskAnswer ->
if(taskAnswer != requirementAnswer.answerValue){
tasks.remove(task)
}
}?: let {
if(requirementAnswer.answerValue == "true"){
tasks[task] = requirementAnswer.answerValue
}
}
} ?: throw ResponseStatusException(HttpStatus.BAD_REQUEST, "Wedding doesn't exist")
return tasks.map { it.key }
}
With SQL you can do use subselects to compare the counts:
select t.*
from task t
join task_requirement tr on t.uuid = tr.task_id
join requirement r on tr.requirement_id = r.id
join requirement_answer ra1 on r.id = ra1.requirement_id
join wedding_requirement_answer wra1 on ra1.id = wra1.requirement_answer_id
where wra1.wedding_id = 1
and ( (select ra2.requirement_id
from requirement_answer ra2
join wedding_requirement_answer wra2 on ra2.id = wra2.requirement_answer_id
where wra2.wedding_id = wra1.wedding_id
and ra2.requirement_id = ra1.requirement_id))
=
(select ra3.requirement_id
from requirement_answer ra3
join wedding_requirement_answer wra3 on ra3.id = wra3.requirement_answer_id
where wra3.wedding_id = wra1.wedding_id
and ra3.requirement_id = ra1.requirement_id
and ra3.answer_value = 'true');
I'm using google places to retrieve information for a place such as the business name, address, OpenHours and LatLng.
This works 95% of the time, but for some places I receive the error...
"Attempt to invoke virtual method 'java.util.List com.google.android.libraries.places.api.model.OpeningHours.getWeekdayText()' on a null object reference"
Looking on Google maps, I do see these places have open hours information.
//Add a marker when a POI on map is clicked.
map.setOnPoiClickListener { poi ->
map.clear()
val poiMarker = map.addMarker(
MarkerOptions()
.position(poi.latLng)
.title(poi.name)
)
poiMarker?.showInfoWindow()
placeId = poi.placeId
Timber.i("Place ID: $placeId")

here is the class I set up for my database. database handler being the inner class.
import android.content.Context
import android.database.sqlite.SQLiteDatabase
import android.database.sqlite.SQLiteOpenHelper
import android.content.ContentValues
import android.util.Log
import java.sql.Date
class Scores {
var id : Int = 0
var dataBaseName = "ScoreDatabase"
var averageTime = 0.0f
val date = Date(System.currentTimeMillis()).toString()
constructor(averageTime:Float) {
this.averageTime = averageTime
Log.d("Poop", averageTime.toString())
}
constructor()
inner class DataBaseHandler(var context:Context, tableName:String): SQLiteOpenHelper(context, dataBaseName, null,1){
val TABLE_NAME = tableName
val COL_ID = "id"
val COL_AVG = "Average_Time"
val COL_DATE = "Date"
override fun onCreate(db: SQLiteDatabase?) {
val createTable = "CREATE TABLE " + TABLE_NAME +" (" +
COL_ID +" INTEGER PRIMARY KEY AUTOINCREMENT," +
COL_AVG + " VARCHAR(256)," +
COL_DATE +" VARCHAR(256)"
db?.execSQL(createTable)
}
override fun onUpgrade(db: SQLiteDatabase?, oldVersion: Int, newVersion: Int) {
TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
}
fun insertData(score: Scores){
val db = this.writableDatabase
var cv = ContentValues()
cv.put(COL_AVG,score.averageTime)
cv.put(COL_DATE,score.date)
var result = db.insert(TABLE_NAME,null,cv)
if(result == -1.toLong())
Log.d("POOP", "fail score table in addition")
else
Log.d("POOP", "Success score table in addition" )
}
fun readData(): MutableList<Scores>{
var list: MutableList<Scores> = ArrayList()
val db = this.readableDatabase
val query = "Select * from $TABLE_NAME"
val result = db.rawQuery(query,null)
if (result.moveToFirst()){
do {
var score = Scores()
var id = result.getString(0).toInt()
var AvgTime = result.getString(1).toFloat()
var date = result.getString(2).toString()
list.add(score)
}while (result.moveToNext())
}
result.close()
db.close()
return list
}
}
}
I tried this where the scores class and the handler were two separate classes, but it generated the same results.
here is how I write to the database (from 4 separate activities. in each activity the tablename is different. in this one for example it is 'additionDataBase')
val scores = Scores("%.3f".format(timeKeeper.averageNumber).toFloat())
val db = scores.DataBaseHandler(context, "additionDataBase")
db.insertData(scores)
and here is how I read from the database which is in a different activity that shows the averageTime from each table. here is the code for one of them
val context: Context? = activity
val adb = Scores().DataBaseHandler(context!!,"additionDataBase")
val data = adb.readData()
TextViewAdScore.text = data[0].averageTime.toString() + " " + data[1].date
I think I am missing something, but I can't seem to find what it is.
so far, no matter how many times I do this. the output is always 0.0f
Look at what you do in readData:
var score = Scores()
var id = result.getString(0).toInt()
var AvgTime = result.getString(1).toFloat()
var date = result.getString(2).toString()
list.add(score)
id, AvgTime, and date are retrieved but not used in any way, so your code is equivalent to just writing list.add(Scores()). (Side note: there's no reason for them to be var, and why the case inconsistency between AvgTime and the rest?)
My apk is uploaded in the alpha channel, my products created, the buy button if it works.
I'm trying to show several products to buy in a RecyclerView. The purchases work for me. What I could not do is show the price and title of the products.
In my myadapter.kt file I have the following var var p = ArrayList<String>() and function:
fun queryskudetails() {
billingClient = BillingClient.newBuilder(context).setListener(this).build()
billingClient.startConnection(object : BillingClientStateListener {
override fun onBillingServiceDisconnected() {
Log.i("Disconnected", "billing client")
}
override fun onBillingSetupFinished(responseCode: Int) {
billingClient.let { billingClient ->
val skulist = ArrayList<String>()
skulist.add("books")
skulist.add("pens")
skulist.add("keychains")
val params = SkuDetailsParams.newBuilder()
params.setSkusList(skulist).setType(BillingClient.SkuType.INAPP)
billingClient.querySkuDetailsAsync(params.build(), { responseCode, skuDetailsList ->
if (responseCode == BillingClient.BillingResponse.OK && skuDetailsList != null) {
for (skuDetails in skuDetailsList) {
val sku = skuDetails.sku
val price = skuDetails.price
Log.i("skudetails", sku)
Log.i("skuprice", price)
hashMap[sku] = price
println("===== price and sku ======")
println(price)
println(sku)
println("===== /proce and sku ======")
// add price to array p1 (defined as a global variable)
p1.add(price)
}
p = precios
}
})
}
}
})
}
In the section onBindViewHolder which is where I assign the price and title to a textView:
override fun onBindViewHolder(holder: Vholder, position: Int) {
queryskudetails()
print("-----Here array price print [] -----")
println (p)
var text: String = array[position]
Log.i("text", text)
holder.textView.text = text
holder.Price.text = hashMap[text.toLowerCase()].toString() // this does not work for me, retun null
Log.i("price", hashMap["books"].toString())
println(hashMap[array[position]]) // retunr null
holder.btn.setOnClickListener(View.OnClickListener {
Log.i("button", text.toLowerCase())
var skuid = hashMap2[text]
val flowParams = BillingFlowParams.newBuilder()
.setSku(text.toLowerCase())
.setType(BillingClient.SkuType.INAPP)
.build()
val responseCode = billingClient.launchBillingFlow(context as Activity?, flowParams)
})
}
When I show the price in a textview the following code does not work for me:
holder.Price.text = hashMap[text.toLowerCase()].toString() where Price is var Price: TextView = itemView.findViewById(R.id.price)
As a second option I try to use the matrix p1 where I stored all the prices in thequeryskudetails ()function but it returns empty.
How can I do to use the content of the array p1?
The price is stored in the Map: hashMap, to recover it use the sku (identifier in google play console)
hashMap = {sku1=USD 3.99, sku2=USD 1.99, sku3=USD 3.99}
//to recover the values according to the sku (key)
hashMap[sku1] = USD 3.99
hashMap[sku2] = USD 1.99
As I see in your code holder.Price.text = hashMap[text.toLowerCase()].toString() (in the variable Text you must have the identifier (identifier = sku) in order to recover the price of each product ), it is correct, check that in another part is not making conflict or has repeated.
How can I perform geo queries using Squeryl with a postgres backend? The sort of queries I want to run are "return all users within x kilometres", etc.
If geo queries aren't supported directly/through a plugin, how can I run raw SQL queries? I saw one gist and it looked complicated.
Update
Specifically I want to run the following query:
SELECT events.id, events.name FROM events
WHERE earth_box( {current_user_lat}, {current_user_lng},
{radius_in_metres}) #> ll_to_earth(events.lat, events.lng);
This is taken from http://johanndutoit.net/searching-in-a-radius-using-postgres/
