Declares an attribute on the resource

Type can be either a built in type (see Ash.Type) for more, or a module implementing the Ash.Type behaviour.

Opts

• primary_key?(boolean): Whether this field is, or is part of, the primary key of a resource. - Default: false
• default({:function, 0} | {module, atom} | {exactly(:constant), any}): A one argument function that returns a default value, an mfa that does the same, or a raw value via specifying {:constant, value}.

Examples

attribute :first_name, :string, primary_key?: true
