Instance Method Summary

• #ensure_snowflake_sequences ⇒ Object

  Ensures that any tables using a snowflake primary key (:id with timestamp_id default) have their backing

  _id_seq sequences present.

  Instance Method Details

  #enhance_snowflake_db_task(name) ⇒ Object

  # File 'lib/rails/snowflake/database_tasks.rb', line 28
  
  def enhance_snowflake_db_task(name)
    return unless Rake::Task.task_defined?(name)
  
    Rake::Task[name].enhance do
      ensure_snowflake_sequences
    end
  end

  #ensure_snowflake_sequences ⇒ Object

  Ensures that any tables using a snowflake primary key (:id with timestamp_id default) have their backing

  _id_seq sequences present. This is necessary for tables created with id: false and a subsequent t.snowflake :id, primary_key: true where Rails does not auto-create the normal sequence.
