angular - How to map object array to my type array -


i have class:

export class    stuff {       id: string;       namd: string;     }

with angular < 4.3 have call:

getstuff(): observable<stuff[]> {     return this.http.get('api-url-here/stuff')         .map((data: response) => {             return data.json()                 .map((item: any) => {                     return {                     id: item.id,                     name: item.name                 };         });     }) }

with angular >= 4.3 changed this:

getstuff(): observable<stuff[]> {     return this.http.get<stuff[]>('api-url-here/stuff')         .map((data: any) => {             return data                 .map((item: any) => {                     return {                     id: item.id,                     name: item.name                 };         });     }) }

i receiving array of stuff fro api looking that.

[  {"id":1,"name": "name" } ]

as can see code example above have map data twice type shape (stuff[]). there better way of doing angular 4.3+ ?

you using typed response in new httpclientmodule, in first map result parsed.

getstuff(): observable<stuff[]> {   return this.http.get<stuff[]>('api-url-here/stuff'); }

should work. , then

somestaffservice.getstuff().subscribe(staff => console.log(staff));

update:

in case able handle errors in 2 ways. outside of service

somestaffservice.getstuff().subscribe(   staff => console.log(staff),   (err: httperrorresponse) => {     if (err.error instanceof error) {       console.log("client-side error occured.");     } else {       console.log("server-side error occured.");     }   } );

or can subscribe right in service , catch error there. please refer documentation

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
