Question

I have the following routes:

resources :tags do
  collection do
    get 'autocomplete', :constraints => { :format => 'js' }
  end
end

I would like this to only respond to JS requests (it’s only for jQuery autocomplete), for a regular HTML request I think it should be a 404 response, or at least a redirect.

Instead, all requests are converted to JS format by the route, so an HTML request gets a json hash.

It isn’t absolutely critical, but I would be much happier if I could cleanly restrict this route so that HTML requests to it were not allowed. How should that be handled?

Answer 1

In TagsController#autocomplete, do the following:

respond_to do |format|
  # format.html { redirect_to some_path } # enable if you want to handle html requests as well
  format.js
end
