Can I pass default value to rails generate migration?

Question

I want to know if I can pass a default value to the rails g migration command. Something like:

 $ rails generate migration add_         


        

Answer 1

You can't: https://guides.rubyonrails.org/active_record_migrations.html#column-modifiers

null and default cannot be specified via command line.

The only solution is to modify the migration after it's generated. It was the case in Rails 3, still the case in Rails 6
