) i want to get only name and price to be stored in room database
entity class that i am using :
#Entity(tableName = "productlisttable")
data class ProductList_Data(
#PrimaryKey
val uid: Int = 0,
#ColumnInfo(name = "_name")
var name: String? = "",
#ColumnInfo(name = "_price")
var price: String? = ""
)
calling method in main activity and getting red underline error that no values passed for init and all that
saveToRoom(Array<Data>))
i think the way i am calling the method is wrong or what
Use this function to convert and save array in database
#TypeConverter
fun fromStringList(stringList: List<String?>?): String? {
if (stringList == null) return null
val type = object : TypeToken<List<String?>?>() {}.type
return Gson().toJson(stringList, type)
}

I am trying to get data from rest api using retrofit on Android app.
I am trying to reach the data structured below;
sections -> items -> venue -> id (Unique id of the venue)
sections -> items -> venue -> name (Name of the venue)

I searched the forum but did not get any right solution.
I want to store this response in Room database. Can someone help me the correct approach to follow.
Thanks
you should create "CalendarEvent" object and make response of retrofit be like this Call
after that you need to create entities from your models and create dao (contain methods to insert,get,update and delete the data from db)
and in your repository when you receive the data map it to your db entity
with your mapper (you can use extension to map your own data)
I convert that json to kotlin data classes and you can create db entites inspired from those models
data class Address()
data class Attendees(val type: String?, val status: Status?, val emailAddress: EmailAddress?)
data class CalendarEvent(val id: String?, val createdDateTime: String?, val lastModifiedDateTime: String?, val changeKey: String?, val categories: List<Any>?, val transactionId: Any?, val originalStartTimeZone: String?, val originalEndTimeZone: String?, val iCalUId: String?, val reminderMinutesBeforeStart: Number?, val isReminderOn: Boolean?, val hasAttachments: Boolean?, val subject: String?, val bodyPreview: String?, val importance: String?, val sensitivity: String?, val isAllDay: Boolean?, val isCancelled: Boolean?, val isOrganizer: Boolean?, val responseRequested: Boolean?, val seriesMasterId: String?, val showAs: String?, val type: String?, val webLink: String?, val onlineMeetingUrl: Any?, val isOnlineMeeting: Boolean?, val onlineMeetingProvider: String?, val allowNewTimeProposals: Boolean?, val isDraft: Boolean?, val hideAttendees: Boolean?, val responseStatus: ResponseStatus?, val body: Body?, val start: Start?, val end: End?, val location: Location?, val locations: List<Any>?, val recurrence: Any?, val attendees: List<Attendees>?, val organizer: Organizer?, val onlineMeeting: OnlineMeeting?)
data class Body(val contentType: String?, val content: String?)
data class Coordinates()
data class EmailAddress(val name: String?, val address: String?)
data class End(val dateTime: String?, val timeZone: String?)
data class Location(val displayName: String?, val locationType: String?, val uniqueIdType: String?, val address: Address?, val coordinates: Coordinates?)
data class OnlineMeeting(val joinUrl: String?)
data class Organizer(val emailAddress: EmailAddress?)
data class ResponseStatus(val response: String?, val time: String?)
data class Start(val dateTime: String?, val timeZone: String?)
data class Status(val response: String?, val time: String?)

But everytime I'm trying to do the request I'm getting this ERROR:

I know there are many posts on this subject but I couldn't find a solution to my problem. Any help would be appreciated!
This is not retrofit but manual parsing in a Firebase message handler service. I am using KotlinJsonAdapterFactory() when building my Moshi instance.
For some reason it thinks one of the nodes is an array when I am asking for it to be parsed as an object. Here is the JSON:
[
{
"$": {
"updateOrigin": "CIS",
"requestSource": "at20",
"requestID": "0000000000004144"
},
"TS": [{
"$": {
"rid": "202008207681819",
"uid": "L81819",
"ssd": "2020-08-20"
},
"Location": [{
"$": {
"tpl": "PADTON",
"wtd": "17:28",
"ptd": "17:28"
},
"dep": [{
"$": {
"et": "17:28",
"src": "Darwin"
}
}
],
"plat": [{
"_": "2",
"$": {
"platsup": "true",
"cisPlatsup": "true",
"platsrc": "M"
}
}
]
}
]
}
]
}
]
And here are my Data classes:
package com.cniekirk.traintimes.model
import com.squareup.moshi.Json
data class PushPortMessage(
val pushPortMessageItems: List<PushPortMessageItem>?
)
data class PushPortMessageItem(
#Json(name = "TS")
val tS: List<TS>?,
#Json(name = "$")
val messageAttrs: MessageAttrs?
)
data class TS(
#Json(name = "LateReason")
val lateReason: List<String>?,
#Json(name = "Location")
val location: List<Location>?,
#Json(name = "$")
val tsAttrs: TSAttrs?
)
data class MessageAttrs(
#Json(name = "updateOrigin")
val updateOrigin: String?
)
data class Location(
#Json(name = "arr")
val arr: List<Arr>?,
#Json(name = "dep")
val dep: List<Dep>?,
#Json(name = "pass")
val pass: List<Pass>?,
#Json(name = "plat")
val plat: List<Plat>?,
#Json(name = "$")
val stationAttrs: StationAttrs?
)
data class TSAttrs(
#Json(name = "rid")
val rid: String?,
#Json(name = "ssd")
val ssd: String?,
#Json(name = "uid")
val uid: String?
)
data class Arr(
#Json(name = "$")
val arrPassAttrs: List<ArrPassAttrs>?
)
data class Dep(
#Json(name = "$")
var depAttrs: DepAttrs?
)
data class Pass(
#Json(name = "$")
val arrPassAttrs: ArrPassAttrs?
)
data class Plat(
#Json(name = "_")
val platform: Int?,
#Json(name = "$")
val platAttrs: PlatAttrs?
)
data class PlatAttrs(
#Json(name = "platsup")
val platsup: Boolean?,
#Json(name = "cisPlatsup")
val cisPlatsup: Boolean?
)
data class StationAttrs(
#Json(name = "pta")
val pta: String?,
#Json(name = "ptd")
val ptd: String?,
#Json(name = "tpl")
val tpl: String?,
#Json(name = "wta")
val wta: String?,
#Json(name = "wtd")
val wtd: String?,
#Json(name = "wtp")
val wtp: String?
)
data class ArrPassAttrs(
#Json(name = "delayed")
val delayed: String?,
#Json(name = "et")
val et: String?,
#Json(name = "src")
val src: String?
)
data class DepAttrs(
#Json(name = "delayed")
val delayed: String?,
#Json(name = "et")
val et: String?,
#Json(name = "etUnknown")
val etUnknown: String?,
#Json(name = "etmin")
val etmin: String?,
#Json(name = "src")
val src: String?
)
I may just be being stupid but I can't find the issue. Here is how I'm parsing the JSON:
val pushPortMessage = data["body"]
val moshi = Moshi.Builder()
.add(KotlinJsonAdapterFactory())
.build()
val pushPortAdapter = moshi.adapter(PushPortMessage::class.java)
pushPortMessage?.let {
val msg = pushPortAdapter.fromJson(pushPortMessage)
println(msg)
}
you are parsing a list of objects not object so the parsing should be something like this
val pushPortMessage = data["body"]
val moshi = Moshi.Builder()
.add(KotlinJsonAdapterFactory())
.build()
val listType = Types.newParameterizedType(List::class.java, PushPortMessageItem::class.java)
val adapter: JsonAdapter<List<PushPortMessageItem>> = moshi.adapter(listType)
val pushPortMessageList = adapter.fromJson(pushPortMessage )
Issue Basics
ObjectBox version 2.5.1
Reproducibility: [always]
Hi, I am getting this error everytime I want to load my Object even though on saving I checked in the debugger and see that the relation target is not null and everything is saved correctly.
I am having those trhee entity classes
#Entity
data class NetflixCache (
val results: List<NetflixSearchResult>,
#Id var objectBoxId: Long?
) {
var searchParams: ToOne<SearchParams> = ToOne<SearchParams>(this, NetflixCache_.searchParams)
}
#Entity
data class SearchParams(val genrelist: String,
val type: String,
val imdbRatingMin: String,
val countryId: String,
val startYear: Int,
val endYear: Int,
val offset: Int? = 0,
val timeStamp: Long,
#Id var id: Long? = null)
#Entity
data class NetflixSearchResult (
val vtype: String?,
val img: String?,
val nfid: Long?,
val imdbid: String?,
val title: String?,
val clist: String?,
val poster: String?,
val imdbrating: Double?,
val synopsis: String?,
val titledate: Date?,
val year: Int?,
var id: Long,
#Id var objectBoxId: Long?
)
Using this code to save:
val cacheBox = LetsFlixApplication.boxStore.boxFor(NetflixCache::class.java)
val netflixCache = NetflixCache(searchResults, null)
netflixCache.searchParams.target = searchParams
cacheBox.put(netflixCache)
And this code to load:
val cachedResult = cacheBox.all //<-Exception is thrown here
As you can see in debugger when saving, ToOne Object is NOT null:
https://ibb.co/s3tdhqP
This is the exact exception message I am getting:
ToOne object is null inside com.haenles.letsflix.domain.NetflixCache
Issue for me was that data class was missing default values as recommended in the doc:
#Entity
data class User(
#Id var id: Long = 0,
var name: String? = null
)
