使用respond_with来服务404？

Question

I'm trying to serve up a custom 404 response in rails, but I'm not sure how to give the :status to a respond_with function.

I know with render , I can do something like this:

render :status => :not_found, :json => {:response =>"There weren't any results"}

How can I do something like that with respond_with ? Is there even a way to set status codes with respond_with ?

The only reason I'm using respond_with is because, to my understanding, it is proper protocol to use respond_with when you've started with respond_to . If that isn't correct and I should be using render , please let me know!

Answer 1

See the docs ; respond_with takes :status as an option.

respond_with(@user, status: :not_found) do |format|
  format.json { response: "There weren't any results" }
end

Answer 2

Instead of set a specific 404 status in your response, you could just raise a ActiveRecord::RecordNotFound exception and it has the same effect. Check it here
