- implements a turbo response in controller
- display error messages on modal -> able for user to re upload
- removes a pending in spec that now tests error message
Yay, now it works. Not sure the best way to show loading yet.
- currently the Turbo loading indicator shows which is better than nothing (blue bar at top)
- ideally we could show a small spinner over the image thumbnail. need to write some stimulus to hook into turbo lifecycle I guess.
- or we could activate the frame-level loading overlay. refactor loading_controller a bit so that it's applied on the container, then hopefully we can just call change->loading#showLoading. the turbo_stream response could dectivate it.
Didn't even need to touch the controller, because data-turbo-stream tells it to render the turbo_stream format ✨
But you might notice that it doesn't redirect to the right return_url yet. Let's see if we can use more Turbo to avoid the page refresh..
