Rails - Jan 2006 - Underscore character in session var

I stumbled across a weird problem

i can do:
@session[:userid] = 1

but cant:
@session[:user_id] = 1

The second session var doesnt set.
Is there a config setting for this?

yes..

@session[:user_id] = 1
user_id: <%= @session[:user_id]%>

wont work and

@session[:userid] = 1 (in the controller)
user_id: <%= @session[:userid]%> (in the view)

does work...

Are you sure you don''t unset :user_id, or set :userid in a filter/other
place?

Hmmm jup it unsetted somewhere :S
Just blindly copied the code from the agile_web_development book...

i have another question:

in my application.rb file

i have

class ApplicationController < ActionController::Base

def authorize_by_type(name)
..do stuff
end

end

i want to use the authorize_by_type method with the before_filter but my 
php syntaxed brain cant find the solution to that. It seems unpossible 
to me to get the name var put in.

i tried:

before_filter :authorize_by_type("administrator"), :except => 
[:login,:logout]
before_filter(:except => [:login,:logout]) { 
authorize_by_type("administrator") }

it doesnt work


i cant also loop through the session data (after sessiondata has been 
set ofcourse)

i tried this in my view

<% for sess in @session %>
<%= sess %>
<% end %>

@session might not be a hash, but I think you can do:

debug(@session)

If you need that.

And you can do:

before_filter(:except => [:login,:logout]) {
   authorize_by_type("administrator")
}

But what are you doing in the authorize_by_type method? Does that method 
work?

PS:

before_filter(:except => [:login, :logout]) {
   authorize_by_type(:administrator)
}

Is nicer because you are using a role (administrator), and there is only 
one role named administrator.

I think a good rule is:

Use symbols if you would use an integer in 
#{insert_bad_programming_language}

;-). So you COULD do:

authorize_by_type(1)

And check in that method:

def authorize_by_type(type)
  if type == 1
  ...
  elseif ...
  ...
  end
end

But this is better:

def authorize_by_type(type)
  if type == :administrator
  ...
  elseif ...
  ...
  end
end

That doesnt work somehow.
