string as optional parameter for method?

[Varun Goel]

Hi All,
I have one method like def hello(int,string)
Now i want that if user pass int value or string value then it should
search on the basis of one of those.

means i want both as optional parameter.
Please tell me how to do this in ROR.
Thanks
Varun

Dear Varun,

maybe something like this ?


def hello(first=nil,second=nil)
if first.class==Fixnum and second.class==String
p 'you entered something for both int and string'
elsif first.class==Fixnum
p 'you entered something for int'
elsif first.class==String and second==nil
p 'you entered something for string'
else
p 'come on, read the manual!'
end
end


p hello(5,'string')
p hello(5)
p hello('string')
p hello(5.78,nil)
p hello()


Best regards,

Axel
