Hello. I have a program that accesses a metadata (translation) table for column names as well as the ordering of columns for a specific model. Also in there is a collection of bool options such as column_visible_on_form, column_visible_on_screen_quicklist etc. The idea is that our customer can specify to a certain extent how their layout/user interface will appear. To accomplish this, I use

Not sure that works.  I had that initially: auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1)); auto carry = IRB.CreateZExt(cf, Int8Ty); Incr = IRB.CreateAdd(Incr, carry); it makes no difference to the generated assembly

I created a project, made a migration, generated scaffolding...start up webrick and I get nothing. To simplify things, I just started another project and generated a controller, still getting nothing. The index page loads fine, but nothing beyond that.
