• Create a operation for displaying all contributors with specs (just copy current solution). Interactor documentation. Dummy operation class.
• Replace current index implementation to the new operation;
• Allow to pass sorted_by value to operation and return contributors in right order (use relation.order { <field>.desc } method.
• Update frontend to send sorted_by value to operations

Do you mean you want to add the ability to sort by created_at, project and title in a given contributor show page?

If so, do we need to add columns to the table to show these info? Sorting will be activated by clicking a link in the show page, using query params?

[davydovanton]

yep, I want to see ?sorted_by=project param, we can update relation query and add search by key

[suryakun]

May I try to take this?
