Mongoose search for element in utmost sub array - arrays

Question

My schema is as follows
{
product:[{
structure :[{
version:[{
type:[{
values:[{}]
}]
}]
}]
}]
}
Need to search fields in values array.
Actually I need to update the fields in values array. I'm unable to write query to get sub array values. How can I do that. Kindly let me know, as soon as possible.

Answer 1

You can use this types of query:
// match a one name
db.getCollection('test').find({"product.structure.version.type.values.name":'test'})
// match some value from an array
db.getCollection('test').find({"product.structure.version.type.values.name": {$in: [1, 'test']}})
Last query will find 3 items in the next collection:
/* 1 */
{
"_id" : ObjectId("595b9e17c482ca1b99db23a6"),
"product" : [
{
"structure" : [
{
"version" : [
{
"type" : [
{
"values" : [
{
"name" : 1
}
]
}
]
}
]
}
]
}
]
}
/* 2 */
{
"_id" : ObjectId("595b9e68f9f2fe8d79ca4c82"),
"product" : [
{
"structure" : [
{
"version" : [
{
"type" : [
{
"values" : [
{
"name" : 3
},
{
"name" : 4
},
{
"name" : 1
}
]
}
]
}
]
}
]
}
]
}
/* 3 */
{
"_id" : ObjectId("595b9e71f9f2fe8d79ca4c84"),
"product" : [
{
"structure" : [
{
"version" : [
{
"type" : [
{
"values" : [
{
"name" : 5
}
]
}
]
}
]
}
]
}
]
}
/* 4 */
{
"_id" : ObjectId("595ba08af9f2fe8d79ca4cd9"),
"product" : [
{
"structure" : [
{
"version" : [
{
"type" : [
{
"values" : [
{
"name" : 6
}
]
}
]
}
]
}
]
}
]
}
/* 5 */
{
"_id" : ObjectId("595ba0f1f9f2fe8d79ca4d00"),
"product" : [
{
"structure" : [
{
"version" : [
{
"type" : [
{
"values" : [
{
"name" : "test"
}
]
}
]
}
]
}
]
}
]
}
UPDATE:
To do an update query, you need to do something like this:
db.getCollection('test').update({"product.structure.version.type.values.name": {$in: [1, 'test']}}, {$set: {"product.$.testProp": 'some test string'}}, {multi: true})
