示例1: createNewMigrationFile

export async function createNewMigrationFile(
  kiln: IKiln,
  connection?: sequelize.Sequelize,
): Promise<string> {
  const models = kiln
    .buildAll()
    .filter(result => result.extensionName === SQL_EXECUTOR)
    .map(result => result.value.sequelizeModel) as SequelizeModel[]

  for (const model of models) {
    if (!(model as any).rawAttributes || !Array.isArray((model as any).options.indexes)) {
      throw new Error('Sequelize has changed! Unable to create migration')
    }
  }

  const upMigrations = await computeMigrations(models, connection)
  const downMigrations = computeReverseMigrations(upMigrations)

  // TODO: topological sort of models to avoid foreign key issues
  const up = upMigrations.map(createStatementFor)
  const down = downMigrations.map(createStatementFor).reverse()

  const wrapInFn = (stmts: string[]) =>
    `async (queryInterface, Sequelize) => {\n${normalizeWhitespace(
      awaitAll(stmts, 2),
      2,
      false,
    )}\n}`

  const migration = `
    module.exports = {
      up: ${normalizeWhitespace(wrapInFn(up), 6)},
      down: ${normalizeWhitespace(wrapInFn(down), 6)},
    }
  `.trim()

  return normalizeWhitespace(migration)
}
