Hello folks,

I do have a hard time with a generator that come with the active  
active-rbac-plugin (v0.5).  
In order to find the source of the problem I did compare the existing  
controller generator with the active-rbac one.

With the same version of ruby (1.8.6), rails (1.2.4) and windows xp  
pro this works

ruby script/generate controller Admin index

and this doesn´t

ruby script/generate rbac\_bootstrap Test

With the later one I get the following error message:

undefined method `error_messages_for' for #<Rails::Generator::Commands::Create:0x470d470> C:/Programme/InstantRails/Rails_1_2_4/ruby/lib/ruby/1.8/delegate.rb: 268:in`method\_missing’

As far as I can see I think it has something to do with ERB. It seems  
not to know the ‘error\_messages\_for’ helper.  
What can be the reason?

The rbac\_bootstrap\_generator.rb files looks like this:

* * *

class RbacBootstrapGenerator \< Rails::Generator::NamedBase  
def manifest  
record do |m|  
m.directory File.join(‘app/controllers’)  
m.directory File.join(‘app/models’)  
m.directory File.join(‘app/views/auth’)  
m.directory File.join(‘test/unit’)  
m.directory File.join(‘test/functional’)

```
  # create controller files
  m.template 'auth_controller.rb', 'app/controllers/

```

auth\_controller.rb’

```
  # create views
  %w( login logout ).each do |str|
    name = "#{str}.rhtml"
    path = "app/views/auth/#{str}.rhtml"
    m.template name, path
  end

  # create controller tests
  m.template 'auth_controller_test.rb', 'test/functional/

```

auth\_controller\_test.rb’

```
  # create models and tests
  %w( anonymous_user user role static_permission ).each do |str|
    m.template "#{str}.rb", "app/models/#{str}.rb"
    m.template "#{str}_test.rb", "test/unit/#{str}_test.rb"
  end

  # create fixtures
  %w( users roles static_permissions ).each do |str|
    m.template "#{str}.yml", "test/fixtures/#{str}.yml"
  end

  # create migrations
  m.migration_template 'add_rbac_schema.rb', 'db/migrate',
    :migration_file_name => "add_rbac_schema"
  m.migration_template 'insert_rbac_records.rb', 'db/migrate',
    :migration_file_name => "insert_rbac_records"

  # modify application_controller.rb
  file_contents = File.read('app/controllers/application.rb')

  if file_contents.match(/ActionController::Base/).nil? then
    file_contents << %Q{

```

# COULD NOT FIND substring “ActionController::Base”! You have to add

the

# following line manually to your ApplicationController:

# 

# acts\_as\_current\_user\_container :anonymous\_user =\> AnonymousUser

}  
else  
file\_contents.gsub!(/ActionController::Base/, “\0\n  
acts\_as\_anonymous\_user :anonymous\_user =\> AnonymousUser”)  
end

```
  File.open('app/controllers/application.rb', 'w') do |f|
    f.write(file_contents)
  end
end

```

end  
end
