2 "newbie questions"

Rails
1

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

  1. 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 !!!

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

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?

def activate
self.active = 1
end

-> This works! Many thanks Felipe!

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
