Как насчет задания на выходные? 

```
if weekend_task
  Task.create([
    { title: 'first_assignment', body: 'do something. have fun', deadline: '1 day' },
    { title: 'second_assignment', body: 'do refactoring. test all', deadline: '2 days' },
    { title: 'third_assignment', body: 'die hard git push heroku master', deadline: '3 days' }
  ])
else
  respond_to format.js { render: study_js_path}
end
```
