I had that same need time ago. I solved it this way:
- permissions as fields in Role:
create_item :boolean, :default => false
update_item :boolean, :default => false
delete_item :boolean, :default => false
create_category :boolean, :default => false
....etc....
habtm :roles :users
roles_controller:
active_scaffold :role do |config|
Role.columns.collect{ |c| c.name if c.type
== :boolean }.compact.each{ |c|
config.columns[c].form_ui = :checkbox
config.columns[c].inplace_edit = :true
config.columns[c].weight = 3 # to get name as first column and
checkboxes all together
}
end
this will give you a big table which lets you have a global view of
permissions and change them without "editing" role by role, just
clicking checkboxes over the big table.
and for the users:
active_scaffold :user do |config|
config.columns[:roles].form_ui = :multi_select
## ..etc...
end
