Constructor Details
#initialize ⇒ Schema
The internals of an Active Resource Schema are very simple - unlike an Active Record TableDefinition (on which it is based). It provides a set of convenience methods for people to define their schema using the syntax:
schema do
string :foo
integer :bar
end
The schema stores the name and type of each attribute. That is then
read out by the schema method to populate the schema of the actual
resource.
