Remove embedded document in a nested array of documents

Question

My schema looks like this:

\"content\" : [
        {
            \"_id\" : ObjectId(\"4fc63de85b20fb72290000f8\"),
          


        

Answer 1

You are so close! Remember that your outermost "content" is an array itself. So the following 2 character change works, use content.$.assets inside the value for $pull.

db.presentations.update(
  {'content.assets._id': ObjectId('4fc63def5b20fb722900010e')}, 
  {$pull: {'content.$.assets': {'_id': ObjectId('4fc63def5b20fb722900010e')}}}
)
