Rails Routes - Limiting the available formats for a resource

Question

I have a series of resources that I want only available if accessed via the JS format. Rails\' route resources gives me the formats plus the standard HTML. Is there a way

Answer 1

If you need not only one or another than json (cant use #xhr?) I offer to you option below

resource :offers, only: :show, format: true, constraints: { format: 'pdf' }

Hope it helps
