Hi, I actually have this on my projects, I still need to make it public, but I was trying to make it more stable first.
The main idea was to be able to add anything inside the brackets, so you could include anything valid as options. The main problem is to use spaces or quotes. rails g migration AddGearsToBicycles gears:integer[default:3 ,limit:10,null:false] In my version, I also create the models (when models are created) using the validations for each parameter, when applicable. Ill try to create an public repo for that in a day or two.
