How can I update an object inside of an array in firestore?

Closed last month.
I have the following collection:
collection firebase
And within this collection (0) I have nested modules -> videos as shown below:
enter image description here
What I want to achieve is that in the section, for example: modules[0].videos[0], the property finishedState = true. I am trying as follows:
try {
const cursos = doc(firebase.db, "misCursos", "7eIHn6FtYIOcFEWq2mXE");
await updateDoc(cursos, {
"0.modulos.0.videos.0.videoFinalizado": true,
});
} catch (error) {
console.log(error);
}
But this removes all other modules with their videos and leaves me only **modules[0] -> videos[0] -> **finishState: true
My question is, how can I do to modify ONLY the property that belongs to that section?

i am stuck with a problem with firebase (with Vue). I want to add the user id to a specific map (yes, maybe or no) when the user presses a specific button. But Im having trouble add/update the data because its nested.
Here is my data structure in Firestore
I want to add the user id in a map, something like this:
dates: {
[
0: {
yes: [userId1, userId2]
}
]
}
Does anyone can help me pushing the user ids into the arrays?
Unfortunately, right now it is not possible to update a specific element of the array. You can add new items or remove them - look here. But I would consider a little change in the approach and create a collection called dates in which you can define documents, which will contain yes, no, maybe arrays, which can be easily updated - in the way mentioned before.

Closed last year.
I am new to React and I searched examples for this questions but I could not achieve to do this.
I make 2 separate calls to backend and getting 2 different dto and I want to put them into one table data instead of 2 separate ones.
Here is my code:
const [lensTableData, setLensTableData] = useState<InternalDTO>();
const [dbsaTableData, setDbsaTableData] = useState<InternalDTO>();
useEffect(() => {
context.services.adapterStatus.getLensAdapterStatus()
.then((resp) => setLensTableData(resp));
context.services.adapterStatus.getDbsaAdapterStatus()
.then((resp) => setDbsaTableData(resp));
}, [])
It is working but what I want to do is to make just 1 array instead of 2 different and I want to add 2nd one into array after the first one. How can I combine them ?

Remove array item from localstorage

Closed 4 years ago.
I have an array of contacts in local storrage, and I need to remove, for example, the first element. How better to do? Is this expression correct?
localStorage.removeItem("allContacts"[0]);
localStorage contains string values. If you stringifyed an array and put it into localStorage, then you'll need to parse the array, delete the element you want, and then set the localStorage property again:
const allContacts = JSON.parse(localStorage.allContacts);
allContacts.shift();
localStorage.allContacts = JSON.stringify(allContacts);
