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

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,

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'

7

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

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

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

12

He's missing include AuthenticatedSystem from application.rb

13

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

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

15

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