List of Rails Model Types

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

e.g.

foo:stri开发者_开发百科ng 
bar:text 
baz:boolean

etc...

And what do these types map to in terms of default UI elements? Text field, Text area, radio button, checkbox, etc...

The attributes are SQL types, hence the following are supported:

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

These are documented under column in the Active Record API.

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:
