猫鼬在特定条件下按索引在数组中查找值

Question

I need to create a query that find a document in which each of the values of an array field must meet a different condition. Those condition differ by the index of this array.

i read that it can be done, for example, in this way:

var cursor = db.collection('inventory').find({ 
  "dim.1": { $gt: 22, $lt: 30 }
});

here i find document in which the array field "dim" has a value >22 & <30 in the second position.

I need to do the same thing with mongoose. but how?!?

Answer 1

You can use the same query with Mongoose.

Assuming that your Mongoose model is Inventory , this should work:

Inventory.find({ 
  "dim.1": { $gt: 22, $lt: 30 }
}, function(err, docs) {
  // Callback code
})
