I need to change my received data from redux store to another variable (and then modify it). At the moment, I receive data from store after API call and it is stored offices
, but it is not set to my officeData
variable. Does anyone how can I solve that?
This is my code:
const dispatch = useDispatch();
const offices = useSelector((state) => state.office.offices)
const [officeData, setOffices] = useState(offices);
debugger;
useEffect(()=> {
dispatch(getOffices());
setOffices(offices);
debugger
}, [dispatch])
If you don't even enter your useEffect i think it's because you give dispatch
as a dependency.
Effect are triggered when component mount but also when component update (prop or state). So you could do something like that:
import { useEffect } from "react";
const dispatch = useDispatch();
const offices = useSelector((state) => state.office.offices);
const [officeData, setOffices] = useState(undefined);
const [didMount, setDidmount] = useState(false);
// When component mount, load your Offices data
useEffect(() => {
if(!didMount){
dispatch(getOffices());
setOffices(offices);
} else {
setDidmount(true);
}
});
useEffect(() => {
if(didMount) {
// When you update officeData, do your thing
}
}, [officeData]);
I don't know the behavior of useSelector, but i guess it does not trigger a rendering. Maybe you could have a useEffect with offices as dependency , just be careful not to loop !
