SeedRecorder class

Runs seeders, records what they change, and puts it back.

seed in metro live and Seeder.seed use it. While a seeder's up() runs, NyStorage and Backpack report each change to a recording held in the current zone. The record of every seeded seeder is kept in storage under recordKey, so it survives hot restarts.

Static Methods

downAll(List<Seeder> seeders) → Future<List<SeedRun>>

Runs each seeder's down(), last seeder first, stopping at the first failure.

forgetBackpackValues() → void

Forgets the Backpack values kept in memory, as a restart would.

list() → Future<List<Map<String, Object?>>>

Each registered seeder's name, description and when it was last seeded, followed by seeders that are still recorded but no longer registered.

nameFromClass(String className) → String

DemoUserSeeder, DemoUser and demo-user all become demo_user.

nameOf(Seeder seeder) → String

The name seeder runs by: its key in the registered seeders, otherwise its own Seeder.name, otherwise its class name in snake case without Seeder (DemoUserSeeder is demo_user).

restore(Seeder seeder) → Future<void>

Puts back everything seeder changed when it was seeded.

runNamed(List<String> names, {required String direction, bool fresh = false}) → Future<List<SeedRun>>

Runs the seeders named names in direction: up or down.

seedChildren(List<Seeder> seeders) → Future<void>

Runs seeders from inside another seeder's up(), each recorded as its own run. Throws when one fails, so the parent fails too.

upAll(List<Seeder> seeders, {bool fresh = false}) → Future<List<SeedRun>>

Runs each seeder's up() in order, stopping at the first failure.

Constants

recordKey → const String

The storage key the record of seeded seeders is kept under.
