Undefined local variable or method `current_user' for

Hi All, I am using a Plugin mdarby-restful_acl with
restful_authentication and I am following the procedure form
http://github.com/mdarby/restful_acl/tree/master , but I am getting some
irritating error “undefined local variable or method `current_user’
for”, I
know I am missing something but I dont know what?
Can anybody help me regarding this?

Hi,

generally plugins require methods like current_user implemented in
application.rb for integration purposes.
This method should return an object of the user

Okay, but could you please explain it in detail, I mean what I have to
define in application.rb and how to define? And whats the whole
procedure?
Thanks in advance
Shahroon

that depends on your plugin. did you follow all the instructions in
README? what’s your complete error-trace? where does the error occurr?

When I tried to add this row

In environment.rb:

config.gem “mdarby-restful_acl”, :lib => ‘restful_acl’

in my environment.rb file it stopped my server. After commenting this
line I got the above mentioned error. I am getting this when ever I
put this line in my controller

before_filter :has_permission?

And this is really disturbing.

Thanks again,

Shahroon

another one:
did you install the restful_athentication plugin first?
http://techno-weenie.net/2006/8/1/restful-authentication-plugin

even if you installed the “mdarby-restful_acl” gem or plugin you’ll
need the restful_authentication-plugin anyways.

No problem at all, in fact you are helping me a lot.Well I have
installed
my gem “mdarby-restful_acl” and its installation was completed
successfully.
And I have downloaded the auhthentication_acl as well and I think its
installation had some problems and I just put that whole plugin directly
into my vendor/plugin folder.

what do you mean by “some problems”? the current_user-functionality is
provided by “restful_authentication”-plugin. if there are unsolved
problems, you should absolutely take care of them.
here is the latest version:
http://github.com/technoweenie/restful-authentication/tree/master/README.textile#INSTALL

it’s always hard to guess, what could be the problem in other people’s
code, so excuse me for asking:
did you install the gem “mdarby-restful_acl”? (= does it show up on
“gem list”?)

In environment.rb:

config.gem “mdarby-restful_acl”, :lib => ‘restful_acl’

I wrote RESTful_ACL; are you using restful_authentication (like followed
their directions), or did you just install it a plugin?

This error indicates that you’re not actually using
restful_authentication

Yeah I checked it was installed properly, there was no error in
installing
it, i was just mistaken.

He’s missing include AuthenticatedSystem from application.rb

Thanks everyone, you helped me a lot in solving my problem. Now
restful_authentication is working fine but restful_acl isn’t, I am
following
the instructions written here
http://github.com/mdarby/restful_acl/tree/master but when ever i add
this
line of code

config.gem “mdarby-restful_acl”, :lib => ‘restful_acl’

in my environment.rb file my server doesn’t start. And whenever I
comment
this line and then restart my server it works but the controller with
has_permission? doesn’t work. It takes me to denied page.
Please help me in solving this issue.
Thanks & Regards,
Shahroon

It has been solved, everything is fine and working now. Once again
thanks
everyone.
Thanks & Regards,

Shahroon

do you have any console output, error message, log entry or whatsoever?
