Question

I’m trying to query a collection in mongo that’s structured like this…

{
  "type":"apple"
  "quality": {
    "1": {
       "owner":"Dan",
       "age":28    
    },
    "2": {
       "owner":"Joe",  
       "age":21      
    }
    "3": {
       "owner":"Bob",  
       "age":29      
    }
  }
}

I initially tried findOne({"quality.owner":"Dan"}) but that failed. Then I realized it needed to be done like findOne({"quality.1.owner":"Dan"}) … not what I want.

Is there anyway to put a wildcard in place of the 1 or to perform the query the way I’m intending? I don’t know what all the variables will be in the quality objects so I don’t think I can do a “sub-object” match either =/

EDIT:

Unfortunately Re-formatting this data is out of the question for the project as the data is being retrieved by a 3rd party API and those index numbers represent “placement” (1st place, 2nd place…)

With your current schema you can’t query like you want(findOne({"quality.owner":"Dan"})). With embedded documents you can search only with dot notation.

But you can redesign your current schema to be like this :

{
  "type":"apple"
  "quality": [
    {
       number: 1,
       "owner":"Dan",
       "age":28    
    },
    {
       number: 2,
       "owner":"Joe",  
       "age":21      
    }]
  }
}

And then search using dot notation:

findOne({"quality.owner":"Dan"})
