Rails Route 404
159 I'd like to 'fake' a 404 page in Rails. In PHP, I would just send a header with the error code as such: header("HTTP/1.0 404 Not Found"); How is that done with Rails? ruby-on-rails http-status-code-404 share|improve this question edited Jul 8 '12 at 18:12 Andrew Marshall 63.9k12134153 asked Mar 5 '10 at 9:52 Yuval Karmi 9,6022697151 add a comment| 9 Answers 9 active oldest votes up vote 864 down rails raise activerecord recordnotfound vote accepted Don't render 404 yourself, there's no reason to; Rails has this functionality built in already. If you want to show a 404 page, create a render_404 method (or not_found as I called it) in ApplicationController like this: def not_found raise ActionController::RoutingError.new('Not Found') end Rails also handles AbstractController::ActionNotFound, and ActiveRecord::RecordNotFound the same way. This does two things better: 1) It uses Rails' built in rescue_from handler to render the 404 page, and 2) it interrupts the execution of your code, letting you do nice things like: user = User.find_by_email(params[:email]) or not_found user.do_something! without having to write ugly conditional statements. As a bonus, it's also super easy to handle in tests. For example, in an rspec integration test: # RSpec 1 lambda { visit '/something/you/want/to/404' }.should raise_error(ActionController::RoutingError) # RSpec 2+ expect { get '/something/you/want/to/404' }.to raise_error(ActionController::RoutingError) share|improve this answer edited Aug 31 '14 at 9:47 Bob Aman 25k84985 answered Feb 13 '11 at 9:09 Steven Soroka 13.2k23430 178 +1 for adding example test code! –bantic Aug 18 '11 at 16:47 3 There is a reason to do it yourself. If your application hijacks all of the routes from the root. It's bad design, but sometimes un-avoidable. –ablemike Oct 3 '11 at 13:54 6 This approach also

I don't like that Rails maps certain errors to 404s- I think it should be up to the developer to decide whether a URL is invalid, or whether the failure to retrieve an record is an application error. How do we ensure http://stackoverflow.com/questions/27925282/activerecordrecordnotfound-raises-404-instead-of-500 all Rails errors are treated as 500 errors? ruby-on-rails share|improve this question asked Jan 13 '15 at 15:11 Yarin 47.1k89269381 add a comment| 2 Answers 2 active oldest votes up vote 7 down vote accepted First off, if you can manually notify your error logger of the error, that would probably be the best thing to do. Making Rails return a different HTTP status code might break other parts of your application. However, if you absolutely must do so, you can instruct Rails not to return a 404 by removing the corresponding entry from the rescue responses hash. You could do this in an initializer: # config/initializers/rescue_responses_overrides.rb ActionDispatch::ExceptionWrapper.rescue_responses .delete('ActiveRecord::RecordNotFound') Now Rails will send a 500 status code to the browser whenever ActiveRecord::RecordNotFound is raised. You could also remove all entries in a single step: ActionDispatch::ExceptionWrapper.rescue_responses.clear To see which other errors Rails returns different status codes for, you can simply print the hash in the Rails console: pp ActionDispatch::ExceptionWrapper.rescue_responses share|improve this answer answered Jan 13 '15 at 16:03 fivedigit 11.4k42846 add a comment| up vote 7 down vote it was raising an ActiveRecord::RecordNotFound error, which Rails treats as a 404 error instead of a 500 error It's the right thing to do.
