How to show actual page body on unprocessable entity or unauthorized

[frenkel]

With Devise I get a 422 response code back on wrong password. In normal browsers I also see the body of that response. On Hotwire Native however I get this screen and the user can't do anything with it anymore:

How can I disable this behaviour and better emulate a normal browser?

Is nobody else having problems with this behaviour? I can work around it partially by using Turbo drive which handles it correctly, but for example the opening screen of my app might return unauthorized with the login form, but that just shows a big error screen like above instead of the sign in form.

Regular forms should work as expected by default and you can tell devise to use 200 and 302 status codes on login.

The demo has a nice example for this, you can try it out by running the demo app based on the readme: https://github.com/hotwired/hotwire-native-android/tree/main/demo
Then navigating to Resources -> Forms and flash messages section.

The following page will be loaded in the Android app: https://hotwire-native-demo.dev/resources/new
You can see the server returns 422 when an empty form is submitted and hotwire-native-android renders the response correctly.

For Devise, I could get it wokring by commenting out the error_status and the redirect_status in the initializers.

# config/initializers/devise.rb
  # ==> Hotwire/Turbo configuration
  # When using Devise with Hotwire/Turbo, the http status for error responses
  # and some redirects must match the following. The default in Devise for existing
  # apps is `200 OK` and `302 Found` respectively, but new apps are generated with
  # these new defaults that match Hotwire/Turbo behavior.
  # Note: These might become the new default in future versions of Devise.
  # config.responder.error_status = :unprocessable_entity (COMMENT THIS OUT)
  # config.responder.redirect_status = :see_other (COMMENT THIS OUT)

Thanks. That seems to break Turbo though, it complains it wants a redirect instead of 200.

You are right. I checked the project where I got this working. I forgot to mention that, I use custom views for devise and I disabled turbo when I submit the forms related to devise.

I did it something like this:

# app/views/users/sessions/new.html.erb

<%= f.submit "Sign In", data: { turbo: false } %>

Thanks.
