Override Rails scaffold generator

For those who are lazy, here is a quick command to copy the default railties erb templates to the correct location in Rails:

mkdir -p lib/templates/erb/scaffold && \
cp $(bundle info railties --path)/lib/rails/generators/erb/scaffold/templates/* lib/templates/erb/scaffold

Well after a couple months I've found the solution. Instead of creating a new generator as the Rails documentation states, I override the default generator but in my projects lib folder.

The original scaffold_generator.rb is located at ~/.rvm/gems/ruby-2.1.0/gems/railties-4.2.4/lib/rails/generators/erb/scaffold. To add the new file (_info.html.erb) we will add it to the available_views method.

def available_views
    %w(index edit show new _form _info)
end

Hope it helps someone.
