'Admin::UsersHelper' is already used problem

Rails
1

Hi,

I’m getting the next error:

The name ‘Admin::UsersHelper’ is either already used in your application
or reserved by Ruby on Rails.

When trying to run:
ruby script/generate controller Admin::Users

I’ve done something similar with Rails 2.0 with no problems. I have
Rails 2.1.1 now.

Tried to google but found no hints. Just that I’m not the only one with
similar problem.

Any ideas how to fix it?

Thanks

i had the same problem. i am not sure what is causeing the error. what
i did was use a name different than users. i used
Admin::AccountsHelper which worked fine.

Try using:

script/generate controller admin/users

Do you happen to have a model named Admin?

Nvm what I just said earlier. It’s a confirmed bug:

One way I found around it is to temporarily rename the helper with the
same name on the parent namespace before running the script/generate.

Hi,

Thanks for the replies.

Erol how did you actually renamed it? I tried and complains about some
dependencies.

The name ‘Admin::ProblemsHelper’ is either already used in your
application or reserved by Ruby on Rails.
Please choose an alternative and run this generator again.

How would you remane the helper in the above test?

Thanks!

I’m assuming you already have non-namespaced ProblemsController - and
corresponding ProblemsHelper.

Rename problems_helper.rb to problems_helper.rb.bak in your app/
helpers directory.
Run your generate script.
Rename problems_helper.rb.bak to its original name.

Nvm what I just said earlier. It’s a confirmed bug:

#545 Bug colliding classes (when they shouldn't) - Ruby on Rails - rails

Rename problems_helper.rb to problems_helper.rb.bak in your app/
helpers directory.
Run your generate script.
Rename problems_helper.rb.bak to its original name.

Yeah, now it went through.

Thanks!

I had the same problem setting up my categories, so I wiped them out and
then scaffolded the admin before the frontend app and it worked
perfectly.

ruby script/generate scaffold Admin::Categories name:string
parent_id:integer lft:integer rgt:integer

ruby script/generate scaffold Categories name:string parent_id:integer
lft:integer rgt:integer

11

in application.rb

comment “helper :all” and run again.
Like this:

class ApplicationController < ActionController::Base
#helper :all # include all helpers, all the time
end

Update… not so perfectly at first…

  1. It was Category not Categories

ruby script/generate scaffold Admin::Category name:string
parent_id:integer lft:integer rgt:integer

ruby script/generate scaffold Category name:string parent_id:integer
lft:integer rgt:integer

  1. I had to go into the admin controller and views and remove Admin::
    and admin_ from everywhere but the controller class declaration.

  2. Also… I think I’m gonna delete the generated Admin::Category class.

I have to wonder if there’s not a better way… oh well, newbie must
learn.
