LoginGeneratorACLSystem Issue

Rails
1

Hello all,

Again, thank you all in advance for any help here. I am trying to figure
out how to show the role associated with a user, in a template. I am
using the LoginGeneratorACLSystem along with the LoginGenerator. I can
show the first name of the user by writing “<%=
session[:user].first_name %>” but when I write “<%=
session[:user].roles.name %>” it spits out “Role”. I am not sure what I
am doing wrong.

Essentially what I am trying to do is lock down user actions based on
what role they have. If anyone know of a “better” way of doing it than
using LoginGenerator along with the LoginGeneratorACLSystem I appreciate
the input.

Sincerely,

Robert D.

Conrad,

There is not an error produced, per se, but rather a lack of correct
information showing. Here is the model code:

User Model:
has_and_belongs_to_many :roles

Role Model:
has_and_belongs_to_many :permissions
has_and_belongs_to_many :users

Permissions Model:
has_and_belongs_to_many :roles

Now, the permissions and roles definately work correctly, however, when
I insert this code, “<%= session[:user].roles.name %>” into the
“welcome.rhtml” page that is the default after a user logs in, this is
what show in the browser: “You are logged in as an Role”. I would like
to show the actual role of the user, such as “Admin”, etc.

Thank you for your help.

Sincerely,

Robert D.

Chris,

I will try this first thing today. Thank you for your help. I have been
using the console (to a limited extent) and have found it extremely
useful. I am also studying Ruby more so that I will stop asking so many
noob-like questions and will hopefully be able to help out more. Thanks
again.

I’m not familiar with LoginGenerator, but I think the problem is that
session[:user].roles will produce many answers (a user can have many
roles, right?)-- I think you should probably get an array of Role
objects returned. You’ll need to iterate through that array to get the
roles the user has (which may only be one) – something like:

You are in the following group(s):
<% for role in session[:user].roles %>
   <%= role.name %>
<% end %>

It’s always worth turning to the console when you have a strange error
like this (ruby script/console). Takes about 30 secs and gives you an
instant feedback on what sort of object is being returned. Hope this
helps.
