I am trying to remove an object from array in in firestore, but encountered an obstacle what are the requirement or the reference to do the removal ? does one key value in the object sufficient to do the remove or should the object by identical to the one that is getting removed ?
const deleteWeek = async () => {
const docRef = doc(db, 'Weeks', id);
await updateDoc(docRef, {
weeks: arrayRemove({
weekId: '7518005f-7b10-44b6-8e0a-5e41081ee064',
}),
});
};
deleteWeek();
}however week in data base looks like this
{name ,"Week 2"
days : [/*data all kinds*/]
weekId : "7518005f-7b10-44b6-8e0a-5e41081ee064"}If it's an array of object, then you need to know the whole object to use arrayRemove() For example, if the a document looks like this:
{
...data
weeks: [
{
name: "Week 2",
days: [/*data all kinds*/]
weekId: "7518005f-7b10-44b6-8e0a-5e41081ee064"}
}
]
}
You'll have to pass the entire week object in arrayRemove(). It might be better to store such data in sub-collections instead so you can query/delete a specific one.
