How can I group/reuse named scopes in Rails? -


How do I group a named SCOPE? For example, I have two models, users, and activity, a user may have multiple activities.

The activity has two named scopes: 

  activity .ordered_by_created_at activity.top_20

I want to have a new designated scope < Create code> activities. such as 

  activity.recent == activity .ordered_by_created_at.top_20

In this way, I user.activities I can call recently 

  user.activities.recent

Is this possible? Thank you.

When you call the user. ACTIVITY, INTRODUCE you have close_you: Relationship to activities in your user. RB files, activatecord will return an array of all user activities.

Now a la actti. recent. Consider changing the approach of the user (UID) and only your activity. In the RB file, a named_scope finds the users associated with the activity
