# Steering

A job's router can receive arguments computed dynamically by `::steer`.
Steering enables [batch routing](/cookbook/batch_routing).

For example, the following router has hostname and path hard-coded:

```ruby
class DummyJob < Wayfarer::Base
  route do
    host "example.com", path: "/contact", to: :index
  end
end
```

Instead, hostname and path could be provided by `::steer`, too:

```ruby
class DummyJob < Wayfarer::Base
  route do |hostname, path|
    host hostname, path: path, to: :index
  end

  steer do |_task|
    ["example.com", "/contact"]
  end
end
```

Note that `steer` yields the current [task](/guides/tasks).
