mongodb - How to delete depricated string fields in options document? -


lets have collections 'testcol' document validation options in options document.

{      "name" : "testcol",      "type" : "collection",      "options" : {          "validator" : {              "$or" : [                  {                      "phone" : {                          "$type" : "string"                      }                  },              ]          },          "validationlevel" : "moderate",          "validationaction" : "error"      },      ... }

lets want delete these options (i aware can set 'validationlevel' 'off'). can run db.runcommand('colmod'': testcol', validator: {}) , mongodb delete field 'validator' options document. can't same 'validationlevel' , 'validationaction'. db.runcommand('colmod'': testcol', validationlevel: ''), not change leaves me this:

{         "name" : "testcol",         "type" : "collection",         "options" : {             "validationlevel" : "moderate",             "validationaction" : "error"         },         ... }

this unclean! there way rid of deprecated string-field options or way manipulate/access options document of collection directly?

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
