ruby - Undefined method for main:Object (NoMethodError) though method is defined -


i have defined script following code snippet:

check_params param  def check_params(param)  # code end

when run get

undefined method `check_params' main:object (nomethoderror)

ruby expects method declared before call it, try move method definition before call method like:

def check_params(param)  # code end  check_params param
