Mongoid: And - Or query

Question

I have this query:

User.or( { name: 'John' }, { name: 'Sara' } ).or( { age: 17 }, { age: 18 } ) )

It returns the next Criteria:

#<Mongoid::Criteria
  selector: {"enabled"=>true, "$or"=>[{"name"=>"John"}, {"name"=>"Anoun"}, {"age"=>17}. {"age"=>18}]}
  options:  {}
  class:    User
  embedded: false>

But I want to do 'and' betweend two 'or' that return something like this:

#<Mongoid::Criteria
  selector: {"enabled"=>true, "$and"=>[
    {"$or"=>[{"name"=>"John"}, {"name"=>"Anoun"}]}, 
    {"$or"=>[{"age"=>17}, {"age"=>18}]}
  ] }
  options:  {}
  class:    User
  embedded: false>

How would be the query ?

Answer 1

this might help you,

User.where(enabled: true)
    .and( 
          User.or( { name: 'John' }, { name: 'Sara' } ).selector,
          User.or( { age: 17 }, { age: 18 } ).selector
        )

this will return:

#<Mongoid::Criteria
  selector: {"enabled"=>true, "$and"=>[{"$or"=>[{"name"=>"John"}, {"name"=>"Sara"}]}, {"$or"=>[{"age"=>17}, {"age"=>18}]}]}
  options:  {}
  class:    User
  embedded: false>
