when using document’s id as the only criteria in my query what’s the difference between:
Board.only(:_id).find(params[:board_id])
and
Board.where(_id: params[:board_id]).only(:_id)
the only thing i’ve noticed is that printing the result as json when using where it encloses the result in square brackets
findreturns one document.wherereturns an array of documents that match the criteria.
