Good morning . we are trying to send push notification by your Kinvey provider but we 
find some problem about send notification only to some device …

At this time We develop 2 Application develop  by Embarcadero Xe10  platform: 

>> APP “A ”<<<
1) The APP : Insert a record on a Kinvey table named :“UserApp”
2) the APP : waiting push notification  and memorize it on a listBox.. .

>> APP “B ”<<< Sender of Push notification

1) The APP : Insert a record on a Kinvey table named :“Messages”
2) On Kinvey Business Logic  we set a “OnPresave ” Hook in “Messages” table
     And … on it … we write some code that do a query on “UserApp” table 
      and try to send notification to the device that corresponding on the query result ..

===> We try the query … and it work fine …  
   But  the notification doesn’t Work !!   by  method : >>>>push.send(doc, message);  <<<<  Why ?? 

 - if in business Logic… we use method  :   push.broadcastMessage(request.body.message, function(err, result)  IT WORK FINE!

Why ?

Why the broadcast work fine ?

How can I see the “device id” that insert the record on table “UserApp” ?

Where can I see in Kynvwey all device registered ?

Please, can you help us ?

BR

Please.. help.. Thanks a lot!

In your example... 

What do you mean ? Do you mean  that there is a collencion named "user" that have fiel like "firstName" ?

Don't you do the same things that i have do for PahrmacyUsers ? 

Thanks for your attenction

BR.

var push = modules.push, collectionAccess = modules.collectionAccess; 

 collectionAccess.collection('user').find({"firstName": request.body.firstName}, function (err, userColl) { 

if (err) { 

 logger.error('Query failed: '+ err); 

} else { 

   userColl.forEach(function (user) { 

         logger.info('Pushing message to ' + user); 

          push.sendMessage(user, "People who are named " + user.firstName + " are awesome!", function(err, result) { }); }); } });

Hi Wani , thanks for your answer!

Yes.. I try to send push notification to PharmacyUsers… (deive who insert the record....) 
because I think that I lack a concept … :-(

In my idea … I want create a APP (with embarcadero) … that at the first time running… ask to the App user some data…(Age, sex, and so on. )
Than the data  are posted by App to Kinvey Tabe “PharmacyUsers”…  I do like, in the same time that The data are linked with the user App device UID…

Than… in a next time, when I’ll use another App … I can interrogate “PharmacyUser” table  and send notification to the device that insert the funded  record (by business logic query)…

Is that possible ? How can I do ?

Hi,

I lloked at your onPreSave hook code:

• The push.broadcastMessage is sent to registered users of the app.
• Your code seems to be trying to send push notifications to rows in PharmacyUsers collection. That is not possible.

Hi,

Can you share the code for onPreSave hook which doesn't work?

Is this issue happening for both Android and iOS devices?
