How to enable activerecord whitelist_attributes in non-Rails environment?

Hello all, I’m developing a sinatra application and loads ActiveRecord in,

sometimes it will just report warning for mass for attributes,

how can I enable it in non-Rails environment?

checked in rails code, it’s config.active_record.whitelist_attributes = true,

so I add to my top code of sinatra ActiveRecord::Base.whitelist_attributes=true

but no luck, no such method exists in ActiveRecord::Base,

so what’s the class of config.active_record, and when setting whitelist_attributes = true,

in what point it invokes some method of active_record to make it whitelist_attributes aware?

Thanks.

Best Regards

Hello, thanks very much.
