VisualizaçõesFirestore nested maps (object), dot notation doesn't work
I have a nested maps on Firestore, I am trying to update an object into another object using dot notation but it's concatenate the called key with object name in Firestore, if I update this nested map (object) without dot notation, will overwrite the entire map field.
if (doc && doc.exists) {
await doc.ref.update({subscription: {chartslab: {
"options.expiration": new Date(new Date()
.getTime()+(10*24*60*60*1000)),
"options.updatedAt": new Date().toISOString(),
}}}).then(() => {
return res.status(200).send("Document successfully updated!");
});
} else {
await doc.ref.set({subscription: {chartslab: {options: {
expiration: new Date(new Date().getTime()+(5*24*60*60*1000)),
}}}});
return res.status(200).send("Done");
}

If you are using dot notation to update nested field, you must add the complete path in dot notation as shown below:
await doc.ref.update({
'subscription.chartLabs.options.expiration': 'value',
'subscription.chartLabs.options.updatedAt': 'value'
})
There's a package flat which can be useful in this case if you have a lot of nested fields to be updated.
const flatten = require('flat');
const updateObj = flatten({
subscription: {
chartLabs: {
options: {
expiration: '...',
updatedAt: '...'
}
}
}
})
Since you are updating the whole 'options' object, you can try this:
await doc.ref.update({
'subscription.chartLabs.options': {
expiration: '...',
updatedAt: '...'
}
})
