Updating array of objects in mongodb - mongodb

Question

I'm trying to update an array of objects in my simple-schema. Currently, it removes everything in the database and leaves behind:
"careerHistoryPositions": []
My simple-schema looks like:
const ProfileCandidateSchema = new SimpleSchema({
userId: {
type: String,
regEx: SimpleSchema.RegEx.Id
},
careerHistoryPositions: { type: Array, optional: true },
'careerHistoryPositions.$': { type: Object, optional: true },
'careerHistoryPositions.$.uniqueId': { type: String, optional: true },
'careerHistoryPositions.$.company': { type: String, optional: true },
'careerHistoryPositions.$.title': { type: String, optional: true }
});
If console.log form data looks like:
careerHistoryPositions: [Object, Object],
0: Object
company: "Test company"
title: "Test Title"
uniqueId: 1498004350350
1: Object
company: "Test company 2"
title: "Test Title 2"
uniqueId: 149800433221
My update function:
handleFormSubmit(event) {
event.preventDefault();
const { careerHistoryPositions } = this.state;
ProfileCandidate.update({ _id: this.state.profileCandidateCollectionId },
{ $set: {
careerHistoryPositions
}
}
);
}

Answer 1

I managed to fix this by mapping over my object and running 2 separate updates. The first removes the old element and the second adds the updated version. I'm sure there is a better way to do this, however, this does seem to work.
handleFormSubmit(event) {
event.preventDefault();
const { careerHistoryPositions } = this.state;
ProfileCandidate.update({_id: this.state.profileCandidateCollectionId}, { $unset: {
'careerHistoryPositions': {}
}
})
const updatePosition = this.state.careerHistoryPositions.map((position) => {
ProfileCandidate.update({_id: this.state.profileCandidateCollectionId}, { $push: {
'careerHistoryPositions': {
company: position.company,
title: position.title,
uniqueId: position.uniqueId
}
}
})
