I don't know why I'm not getting notification events from sails models from model.publish(). In pre-1.x sailsjs, similar client-side code had worked and I would get every event when records are created, updated or deleted. So, I must be misunderstanding something.
How do I subscribe to all events for any records from CRUD operations?
On the server side, I have Job.js and JobController.js.
In Job.js model, this test just creates a new record every 10 secs:
test: async function(dataset) {
let count = 0;
setInterval(async function() {
count++;
let newjob = {
dataset: dataset,
state: 'delayed',
name: "job name "+count
};
let job = await Job.create(newjob).fetch()
sails.log.info('created test job: ',JSON.stringify(job));
Job.publish([job.id],job);
},10000);
}
In JobController.js, called by the client and starts the test rolling:
submittest: async function(req,res) {
let dataset = await Dataset.Get({});
await Job.test(dataset[0].id);
return res.ok({status:'ok'});
}
In the client test.html, io.socket.get operations are successful, but I never see an event:
...
<script>
io.socket.get('/job', function(body, JWR) {
console.log('and with status code: ', JWR.statusCode);
setTimeout(function() {
io.socket.get('/job/submittest', function (body,JWR) {
io.socket.on('job', function(msg) {
console.log("job event",msg); // not getting here. why?
});
});
},2000)
});
</script>
This all runs fine but the problem is, no events are seen from the client side. Why? Am I not subscribed to events with the initial io.socket.get('/job')?
Essentially, what is happening here, is you are shouting into an empty box about a new record in your model, but no one is listening to you in that empty box.
In other words, you need to subscribe the socket connection to the model updates.
