Hi all,

I am using rails v.2.3.2 and if I put following line to my  
ApplicationController:

include LoginSystem

and I moved my login\_system.rb to lib folder:

module LoginSystem  
protected

def is\_logged\_in?  
@logged\_in\_user = User.find(session[:user]) if session[:user]  
end

def logged\_in\_user  
return @logged\_in\_user if is\_logged\_in?  
end

def logged\_in\_user=(user)  
if !user.nil?  
session[:user] = user.id  
@logged\_in\_user = user  
end  
end

def self.included(base)  
base.send :helper\_method, :is\_logged\_in?, :is\_admin?,  
:logged\_in\_user  
end  
end

This does work under RAILS 2.1.1, but not under 2.3.2  
It says: undefined method `is\_logged\_in?’ for  
#ActionView::Base:0x78cf044

Cheers  
P.

Library methods are not accessible in view.

Hi Petan,

instead of using is\_logged\_in?.  
give a try for logged\_in? method.

still problem then define method is\_logged\_in? method in  
application\_helper

def is\_logged\_in?  
session[:user]  
end

I hope this will work.

Hi Sandip,

I’ve tried to moved all the stuff from login\_system.rb to  
application.rb, but it is still the same.

Is there a another way to solve this trouble?  
Thanks.

I moved all the stuff from my lib/login\_system.rb to the  
application\_helper.

And I got this ubly error: NoMethodError … undefined method  
`helper\_method’ for #Module:0x75f19f8

So I added following line to my application\_controller:

helper\_method :logged\_in\_user, :check\_administrator\_role,  
:check\_moderator\_role, :login\_required, :is\_logged\_in?, :is\_admin?

but still no luck. ☹  
Still the same error.

Cheers

Dont’ do this keep your lib/login\_system.rb as it is.

restart server

lib methods are accessible in controller, only problem with views.

If you wanted to access them in view  
add following line in your application controller  
helper\_method :method\_name
