よくある思い込み

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.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• 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
