Commonly assumed
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.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- 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
