In my api::controller i have few methods which follow the same type of 
structure .
like :-
def index
    render json:{:status => false, :message => 'qw'} if
params[:type].nil?
    @stats = 
ChildStat.get_child_stat(@child_profile.id,@profile.id,params[:type])
    render json:{:status => false, :message => 'Child stats not
found'}  if
@stats.empty?
  end
  def child_vaccines
    render json:{:status => false, :message => "Please specify type: 
weekly, monthly in parameters "}  if params[:type].nil?
    @vaccines = 
ChildStat.get_child_vaccine(@child_profile.id,@parent_profile.id,params[:type])
    render json:{:status => false, :message => "Child Vaccines not
found "}
 if @vaccines.empty?
  end
  def child_meals
    render json:{:status => false, :message => "Please specify type: 
weekly, monthly in parameters "}  if params[:type].nil?
    @meals = 
ChildStat.get_child_meals(@child_profile.id,@profile.id,params[:type])
    render json:{:status => false, :message => "Child meals not found
"} if
@meals.empty?
  end
So the above three methods follow the same structure . I am thinking to 
refactor or else write them in more compact form  . 
I needs your help or suggestion for this .
thanks.
