Before sending API request to insert I want to check the item is already exist in store or not, if not then only send the request to insert.
add(){
const item = {id: 4,name:'test1',description:'description'}
// here i want to check whether test1 already exist or not
this.store.add(item);
this.httpService.insert(item).subscribe(
result => {
this.messageService.handleSuccess('inserted');
this.store.updateId(id, result.id);
},
error => this.messageService.handleError('error on insert:', error)
);
can someone please help?
You can use the query:
add(){
const item = {id: 4,name:'test1',description:'description'}
if(query.hasEntity(4)) {
// exists
}
this.store.add(item);
this.httpService.insert(item).subscribe(
result => {
this.messageService.handleSuccess('inserted');
this.store.updateId(id, result.id);
},
error => this.messageService.handleError('error on insert:', error)
);
