Rails 4: List of available datatypes

Where can I find a list of data types that can be used in Ruby on Rails 4?
Such as

• text

• string

• integer

• float

• date

I keep learning about new ones and I'd love to have a list I could easily refer to.

Here are all the Rails 4 (ActiveRecord migration) datatypes:

• :binary

• :boolean

• :date

• :datetime

• :decimal

• :float

• :integer

• :bigint

• :primary_key

• :references

• :string

• :text

• :time

• :timestamp

These are the same as with Rails 3.

If you use PostgreSQL, you can also take advantage of these:

• :hstore

• :json

• :jsonb

• :array

• :cidr_address

• :ip_address

• :mac_address

They are stored as strings if you run your app with a not-PostgreSQL database.
