Given a schema like this:
UserSchema = new Schema({
name: String,
donations: [
{
amount: Number,
charity: {
type: Schema.Types.ObjectId,
ref: 'charity'
}
}
]
});
I have the (string) ids of a user and of a nonprofit and I want to get the amount the user donated. Im using this query with lodash:
User.findOne({
_id: userId
}, function(err, user) {
var amount = _.find(user.donations, {charity: charityId});
console.log("the amount is: ", amount);
});
Here the amount returns undefined even though it shouldn't also im guessing i shouldn't have to use lodash
. What's the right way to get to the amount donated given a specific userId
and charityId
?
