2 "newbie questions"

Hello -

Being new to Ruby and Rails I am finding some hurdles that kind of
slow my progress.

1. What is the difference between the 2 statements:

staff = Staff.find(params[:id])
and
@staff = Staff.find(params[:id])

I find books and articles using either of them but I fail to grasp why
this should be different

2. This piece of code does not work and I have no idea why:

controlller:

    @subscriber = Subscriber.new(params[:subscriber])
    @subscriber.activate
    @subscriber.save

the function activate is defined in the model:
  def activate
    @active = 1
  end

(active beeing one of the row of the table).

Result: this does not set active to 1.
If in my controller I set @subscriber.active = 1 then it works and the
row is saved with active set to 1.

Thanks for your help !!!

Re: 2 "newbie questions"

Well, talking about rails, if you do in your controller
staff = Staff.find(1), then you can''t use that in your views, because
it
goes out of scope, instead, if you use @staff, it will be available in 
your view. I suggest you to read something about scope and variables.

For the second problem, try tu use active = 1 instead of @active = 1. 
I''m not sure let me know f it works

Re: 2 "newbie questions"

Thanks for the answer. I know understand about the scope thing.
I''ve tried using "active = 1" in my model but this still does
not
work. Any further idea?

Re: 2 "newbie questions"

On the model:

try this:

def activate
  self.active = 1
  self.save #you might even remove this, not sure
end

or, if it does not work, you can always use

def activate(user_id)
  user = User.find_by_id(user_id)
  user.active = 1
end

and then in the controller

User.activate(222) #or whatever the id is

Best regards,

Felipe
