Question

I have an array defined like this,

result = ["true","false","false","false"]

In my code I iterate through the array and raise an exception when i come across false.

begin  result.each  do |method| 
           raise  if (method == false) {
           rescue Exception => Form_Validation_Failure
                  puts "fail!"
           end } 
       end

There is an error when i execute the code.Is this is the right way to raise and exception in Ruby? Could somebody help with this please.

Cheers!

In addition to using strings in your array and the constant false in your comparison, I see a rescue inside braces.

I think the form of code you are looking for is:

>> result = [true,false,true,false]
=> [true, false, true, false]
>>
?> result.each do |method|
?>   begin
?>     raise if not method   # preferred to method == false
>>     puts "ok"
>>   rescue
>>     puts "fail!"
>>   end
>> end
ok
fail!
ok
fail!
=> [true, false, true, false]
