+* +max_paginates_per+
+
+  You can specify max +per_page+ value per each model using the following declarative DSL.
+  If the variable that specified via +per+ scope is more than this variable, max +paginates_per+ is used instead of it. Default value is 0, which means you are not specifying max +per_page+ value.
+    class User < ActiveRecord::Base
+      max_paginates_per 100
+    end
