MongoDB update multiple array items

Question

I have a document with this structure:

{
  codeId: 1,
  generatedCodes: [
    {
      name: 'Code 1',
      status: 'In Progress'
    },
    {
      name: 'Code 2',
      status: 'In Progress'
    },
    {
      name: 'Code 3',
      status: 'In Progress'
    }
  ]
}

I'm trying to update the status property of each object by using the following code:

db.codes.update({codeId: id}, {$set: {'generatedCodes.$[].status': 'Validated'}}, {multi: true})

But none of the array items get the new status...

The id is correct ... there must be something else I'm missing — Valip

can you look at the mongo logs and see the exact query that is executed? — Eli Skoran

Run this command in mongo shell db.adminCommand( { setFeatureCompatibilityVersion: "3.6" } ). — Ashh

i just run the following and it worked:

db.getCollection('yourCollection').update({codeId: 1}, {$set: {'generatedCodes.$[].status': 'Validated'}}, {multi: true})

the only difference from your code is that i changed {codeId: id} to {codeId: 1}
so make sure you are passing the correct id.

And it updated all the status property for all objects?

yes.

{     "_id" : ObjectId("5b6bfdb818f454e0492896f1"),     "codeId" : 1,     "generatedCodes" : [          {             "name" : "Code 1",             "status" : "Validated"         },          {             "name" : "Code 2",             "status" : "Validated"         },          {             "name" : "Code 3",             "status" : "Validated"         }     ] }
