Mongodb - Modelling a product catalog with user specific pricing -

-

looking @ mongodb product catalog example (for data caching lookups), how best implement pricing , qty available specific user logged in. picturing layout this:

[{"_id":"skua",   "details":{ "msrp": "$15", "short_desc": "my short description"} , "priceqty" : [{"custid": 1, "price":10 , "qty":25 },{"custid": 2, "price":9 , "qty":20 }] }]

(but need push in updated (or add if first log in) pricing when user logs in (ex: remove custid = 1 documents , push in ). or make sense keep item information in 1 place , create separate collection holding sku, price, customer, , qty? not sure how use reference id on sql left join item collection pricing collection second approach.

the item collection hold 100k+ (for quoting purposes) pricing , qty hold 2k ordered on spot. unfortunately, have mind in relational world still.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
