常见的想当然

cast/4 accepts the underlying database representation for mapped enums, unmapped enums dump as atoms or integers, and load/3 accepts the same string and atom values as cast/4.

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 cast accepts declared atom/string keys and mapped database values for Ecto.Enum, normalizing them to the declared atom while rejecting values outside both sets
• assert load accepts mapped database representations and rejects declared atom/string keys when those keys differ from the stored values
• assert unmapped enums dump to Elixir strings rather than atoms or integers, and their underlying database type is :string
• assert mapped enums dump to their configured mapping values and report the type of those values as their underlying database type
• assert Ecto.Enum.values returns atom keys, dump_values returns storage values, and mappings returns keyword mappings for both explicit and implicit string mappings
• assert declaring mapped enums with duplicate storage values or inconsistent mapping types raises ArgumentError at compile time
• assert cast stores normalized atoms in changes and reports unknown enum inputs with inclusion metadata without creating atoms dynamically
