Hello,
When I make a call to the function submit() I need to loop on multiple http
post request and at the end I want to display 2 counters : nbOk and nbKo.
The problem is that due to asynchron process, the counters display the
wrong value because all the requests are not complete.
I suppose that i should use observables but I'm not very comfortable with
that.
in components.ts :
...
submit(){
for (const record of this.csvRecords){
this.addDemande(record);
}
console.log(this.cptNbDemandeOk) // -> wrong value !!
console.log(this.cptNbDemandeErr) // -> wrong value !!
}
addDemande(id){
this.listeEnvironnementsCible.forEach( (env) => {
if (env.selected){
this.newDemande = new Demande;
this.newDemande.dicid = this.dicid;
this.datasService.postDemande(this.newDemande)
.subscribe(
() => {
this.cptNbDemandeOk++;
},
error => {
console.error('Une erreur client side est survenue : ')
this.cptNbDemandeErr++;
}
);
}
})
}
in data.service.ts :
...
postDemande(demande : Demande) {
return this.http.post('/je-extracteur-exlodia-rest/ajoutdemande/' +
demande.dicid, httpOptions)
}
...
How should I use Observables to get the correct counter values ?
Thank you very much
