Ruby-on-rails – Ruby on Rails generates model field:type – what are the options for field:type

generatorrails-activerecordruby-on-rails

I'm trying to generate a new model and forget the syntax for referencing another model's ID. I'd look it up myself, but I haven't figured out, among all my Ruby on Rails documentation links, how to find the definitive source.

$ rails g model Item name:string description:text (and here either reference:product or references:product). But the better question is where or how can I look for this kind of silliness easily in the future?

Note: I've learned the hard way that if I mistype one of these options and run my migration then Ruby on Rails will totally screw up my database… and rake db:rollback is powerless against such screwups. I'm sure I'm just not understanding something, but until I do… the "detailed" information returned by rails g model still leaves me scratching…

Best Solution

:primary_key, :string, :text, :integer, :float, :decimal, :datetime, :timestamp,
:time, :date, :binary, :boolean, :references

See the table definitions section.
