Awesome here. Let me suggest you that instead of

```
def set_routine
  @routine = Routine.find_by(id: params[:id])
end
```

You do something like:

```
def set_routine
  @routine = Routine.find(params[:id])
end
```

`.find_by` returns `nil` when it doesn't found nothing and then you could face `NoMethodError for NilClass`.

`.find` raises an exception and you can better handle that with a notification or message or something.
