How to delete a certain field in an array inside Meteor collection?
I can't delete a field inside an array in Meteor collection. Here is the structure of my collection:
I have tried this:
SMUProfiles.update({
owner: this.userId,
'classrooms.owner': classroom_id,
}, {
$pull: {
'classroom.$.owner': classroom_id
}
}
)
but unsuccessful.
I want to delete any of the key under 'owner' array, and I only have reference to its value, and not their index. In this case, I have a reference to 6Yi64LqpqnfsHv4ms as classroom_id.

Did you try
SMUProfiles.update({
owner: this.userId,
}, {
$pull: {
'classrooms.owner': classroom_id
}
}
)
I think simple pull operator with object path should be enough to pull elements from array.

Apparently, there's no easy way to do that currently. So, for the benefit of others who might be looking at a similar problem, here's my solution:
//** Method for deleting Classroom */
'classroom.delete'(classroom_id){
if(!this.userId){
throw new Meteor.Error('not-authorised');
}
Classrooms.remove(classroom_id)
let classids = Classrooms.find({ owner: this.userId
}).fetch().map(function(classrooms){
return classrooms._id })
//console.log(classids);
SMUProfiles.update({
owner: this.userId,
}, {
$set: {
'classrooms.owner': classids
}
}
)
},
The story behind this solution:
I have 2 collections Classrooms and SMUProfiles. Upon registration, a new record will be created under SMUProfile for that user, containing several other details (refer to the picture attached in the question above), including a record of the classroom ids that user has created.
Now, when the user delete a classroom in Classrooms collection, i need to also delete the id of the classroom that has been deleted, in SMUProfile. I was originally trying to delete the id from the array of ids in SMUProfile but was not successful.
I solved this by re-reading the Classrooms collection after a classroom has been deleted, re-iterate the ids of the remaining classrooms inside an array, and $set that new array of classrooms ids to SMUProfile.
