Hi,
For some reason I can''t get the following class to work,
here is
the setup.
1. I have the following method in the controller
def suggestions
@suggestion = Suggestion.new("Jonny Doe", "Developer")
render :text => @suggestion.name
end
2. Here is the class
class Suggestion
def initialize(name,profession)
@name=name
@profession = profession
end
def name
@name
end
end
3. When I go to the suggestions action I get the following error:
ArgumentError in Shahablab#suggestions
wrong number of arguments (2 for 1)

Any ideas about what I am doing wrong? I realize that I can use
attr_accessor to get/set the name attribute but right now I would just like
to get this working.
Thanks!

Hi,
I sent the following e-mail in the morning but my subscription
to the list didn''t get processed until now. I am not sure where I can
see if
someone has answered. Any help? Please forgive the extra spaces, I had to
copy this from a web interface :-(.
Thanks!

Hi, The problem is the initialize() definition. The framework expects a 3-argument version while you have defined a 2-arg version. I would suggest that you not use initialize at all and instead do initialization after constructing objects.
