List of Rails Model Types

Question

Does someone have a complete list of model types that be specified when generating a model scaffolding

e.g.

foo:string 
bar:text 
baz:boolean
         


        

Answer 1

You can use the following basic field types in model scaffolding, all are supported in ActiveRecord supported databases without any extra gem (MySQL, PostgreSQL, SQLite):

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

In the scaffold generator you can also declare the foreign references using :references field type, which additionaly adds a belongs_to reference in the new model.

If you use Rails 4 and PostgreSQL, you can take advantage of these:

• :hstore
• :array
• :cidr_address
• :ip_address
• :mac_address

For UI mapping (Model scaffold data type -> HTML), the next image has all the basic field types:
