```cucumber
Given a developer has Person and Article models
When he/she uses Ransack on Person, but searches for people who have published articles on the last 30 days
Then he/she should be able to retrieve Articles on the last 30 days without additional scoping
```

Right now, I have to find the appropriate param, see if it's present, and then use it on scopes. person.articles just fetches all the associated articles.
