Rails - generate scaffold for multi select

I used the following method to generate scaffold for platform list in our app:
rails generate scaffold platform name:string url:string country:string
I would like to still use scaffold possibility to add additional attributes, like type and gender, which should be drop downs, or preferably multi-select's.
Is there a way to use rails generate to create such a models?
Soluzione
You have already generated a scaffold for Platform. So you have two options:
- edit scaffold by hand to add the new fields (recommended)
- remove scaffold with
rails destroy scaffold
and then userails generate
again
Anyway scaffolding doesn't allow you to specify options for a drop-down menu. In any case you have to manually edit the scaffold. Furthermore in Rails migrations you cannot specify ENUM fields, so the best option for gender would be a string field with unitary length (with a validates_inclusion_of
in model).
P.S. Don't use type
as a column name because you will probably get strange behaviors.
