It's not related to AS, you want to build an URL in rails, you don't want to change the records shown by AS. If you need to set more variables in the list action, you can override do_list method, calling super in order not to lose AS code, or set a before_filter to some actions. You can load all records in rails, and pass all ids as argument in the url, but is a bad idea to build so long URL and to send so much data. You can get all records you need in reports controller. Also it's better to select all records without adding "where id IN (all id list)" to select query, it would be slow to build, and slower to execute. If reports controller build a report for records you pass, add another action to build a report for all records. I think it's more a rails issue than AS issue, it would be better to ask in a rails list instead of a rails plugin list as this one if you have doubts about how to do that controller. Anyway if you need some help about how to link some AS controllers with your report controller, or how to override some AS views, explain where you want to add that link, if there is a report model, what associations between your models and so on. Also you can add a report action to your controller. Report action it would use @records = Model.all to get all records. If you want to build reports for multiple models, set in a module and include it in some controllers. You can use active_scaffold_config.model instead of Model if you use AS in all of those controllers, in other case you will have to guess model from controller name or add a method in each controller which returns the model class. -- Sergio Cambra .:: entreCables S.L. ::.
