Question

How do I change

validates_numericality_of :test, :greater_than_or_equal_to=>0 

into validate form

I tried only character and nil values. I need to check also it must be greater than 0

validate change_test

def change_test
  if @test.nil?
     errors.add_to_base('Hi Test should be only number')
  end
end

and also I tried like this,

validate change_test

def change_test
  if @test.nil?
     errors.add_to_base('Hi Test should be only number')
  else
    if @test < 0
     errors.add_to_base('The number should be greater than or equal to 0')
    end
  end
end

but it is result in error

Please help to solve this problem

thanks all

Answer 1

1. Give the error message, it’s a lot easier to diagnose the problem.
2. Use built in validations, learn how to change their messages (:message parameter to validates_numericality_of)
3. if @test < 0 should rather be if @test.to_i < 0
