Drgcms controls
Every form can have its own control file. Methods from control file are included into CmseditController and become part of controller when controller actions are called. Control methods can be used as callbacks called before or after record load and save or as actions defined on forms. There are 6 available callbacks:
- dc_new_record
- dc_before_edit
- dc_before_save
- dc_after_save
- dc_before_delete
- dc_after_delete

def dc_new_record()
@record.user_id = session[:user_id]
@record.time_begin = Time.now
end

def notes_filter()
user_filter_options(Note).and(user_id: session[:user_id]).order_by(created_at: -1)
end
end
dc_new_record method is called after new document is created. It can be used to initialize fields with values that can not be accessed within model definition.
notes_filter method is used to filter documents presented to user. Method name is defined under form result_set: filter: option. Method ensures that only documents which belong to currently logged user are presented to user. user_filter_options method mixes additional filter options defined by user with criteria defined in notes_filter.
