常见的想当然

Parameterized types in Ecto schemas are represented as three-element tuples of {:parameterized, module, params}, and casting an Ecto.Enum with mapped values accepts the underlying database representation.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• assert schema type for an Ecto.Enum is a 2-element tuple {:parameterized, {Ecto.Enum, info}} rather than a 3-element tuple, Ecto.Type.parameterized? identifies it, and Ecto.Type.type returns the underlying primitive storage type
• assert casting an Ecto.Enum with mapped values accepts atom keys, string names, and raw mapped integers, while rejecting stringified integers with inclusion metadata
• assert Ecto.Enum reflections distinguish between Elixir value atoms, database dump values, and key-value mappings
• assert Ecto.Type.cast! returns normalized scalar values and raises Ecto.CastError on failure, while invalid composite arrays collapse to :error and changesets omit the failing element index
