Rails link_to :format => :xlsx not generating link to .xlsx path

Question

If I hit this url: http://localhost:3000/reports/action.xlsx it shows a generated xlsx file.

If I have a link_to like this:

<%= link_to 'Export to Excel', reports_affirmative_action_path, :format => :xlsx %>

It generates a link to this page: http://localhost:3000/reports/action

Why does my link_to with :format => :xlsx not link to the correct path?

Answer 1

Your link_to and path are slightly off. You want

<%= link_to('Export to Excel', reports_affirmative_action_path(format: :xlsx)) %>

Where the format is an argument to the path helper, not link_to.
