ActionController::RoutingError (No route matches [OPTIONS] "/assets")

[zpaulovics]

Hi,

In a Rails 4.2 application I have changed config parameter in the config/environments/porduction.rg file
from config.serve_static_assets = false
to config.serve_static_files = false
according to the deprication message. Since that time I have got the following fatal error:

I, [2015-01-14T12:43:41.747355 #22151] INFO -- : Started OPTIONS "/assets/" for 91.120.37.4 at 2015-01-14 12:43:41 +0100
F, [2015-01-14T12:43:41.756075 #22151] FATAL -- :

Can you please provide a sample application that reproduces the error?

@zpaulovics It's been some time without feedback. Do you still experience that problem? If so, please provide a sample application to reproduce the problem, this goes a long way in debugging the issue.

Hi, unfortunately I could not reproduce the problem.

You see this when the remote app sends an OPTIONS http verb. I'm hitting this using the Ionic framework from a phone - I think it's some kind of check to see if the host will accept XSS. You can get match to give you the verb thus:

match '/v1/phone/register', to: 'v1_phone#options', as: :phone_register_options, via: :options

and the options method looks like this

def options
  headers['Access-Control-Allow-Origin'] = request.env['HTTP_ORIGIN']
  headers['Access-Control-Allow-Methods'] = 'POST, GET, OPTIONS'
  headers['Access-Control-Max-Age'] = '1000'
  headers['Access-Control-Allow-Headers'] = '*,x-requested-with'
  head :ok
end

I've got past this now but still fighting with the JavaScript in Ionic asking for options and then not doing the second call for data. I hope this helps someone else make some progress :)
