Image Attachments in ActionText not showing due to routing

Benjamin Deutscher asked in Rails

I am desperatly trying to get my ActionText site working in production. I have a it working in development. In production the upload and editing is working fine, I get the images saved on local disk. But when showing the page I only get a broken image. Visiting the image url will result in an error 404.

The URL is something like
Using rails c I get all attachments of the rich_text body. Is there a route I need to configure to get the images to show?

Some more information

  • I am running unicorn and nginx
  • ruby 2.6.5p114
  • rails


  service: Disk
  root: <%= Rails.root.join("storage") %>


 # Store uploaded files on the local file system (see config/storage.yml for options).
  config.active_storage.service = :local


Rails.application.routes.draw do
  resources :pages, param: :seo_url, path: 'seite'

  get '/index', to: 'application#home', as: :home
  root to: 'application#home'



Looks like it's using for the domain so you're probably missing one of the configs to set the default host.

Lots of chat about it in this thread.

And one of the recommended options to try is:

config.active_storage.service = :local
config.action_mailer.default_url_options = { host: '' }
config.default_url_options = { host: "" }

Hi Chris,
thanks for your response! I might haven't made my problem clear enough. I do get the correct link to the image with my real domain. URL wise everything looks fine so far. It is just the link itself that is not working. Sorry for the inconvenience!

This is the output that is produced. MYDOMAIN is my actual domain.

I was able to solve my problem. I misconfigured my nginx. I pasted the wrong config snippet for static image delivery into the config. This is actually so embarrassing!

Thank you very much for your help.



Could you please explain how you configured nginx because I am having the same problem.
