Rails 4 Error 422 on heroku with ajax button

My Rails 4 app works fine locally but when I deploy to heroku I keep
getting the error “422 Unprocessable Entity” for a particular ajax
request:

<%= button_to update_profile_picture_path(
                params: {
                  picid:    standardpicture.id,
                  callsign: character.callsign,
                  authenticity_token: form_authenticity_token # 

doesn’t
work with or without this
}
),
class: ‘btn btn-default btn-xs’,
remote: true do %>

<% end %>

which hits this controller action:

def update_profile
  @character = Character.find_by(callsign: params[:callsign])
  standardpicture = Picturething.find_by(id: params[:picid])
  @character.build_profilepicture
  standardpicture.picture.recreate_versions!
  @character.profilepicture.picture = 

standardpicture.picture.profile
@character.profilepicture.save!
respond_to do |format|
format.html do
redirect_to @character.sociable
end
format.js
end
end

I’ve done everything suggested on SO:

application_controller.rb

protect_from_forgery # doesn't work with with: :exception or with:

:null_session

application.html.erb

<%= csrf_meta_tags %>

I’ve also tried deleting cookies and clearing the cache.

Have a look in production.log and you should get more information.

Ok, here are the local logs and the production logs. While the local
logs
don’t have any errors the production logs are complaining about the line

picturethings_controller.rb:12:in `update_profile’

Update:

Removing MiniMagick partially solves the problem - the ajax request goes
through without error, returning this js:

$('#profilepic').html('<img

src=“https://websmash.s3.amazonaws.com/uploads/picturething/picture/5/baz1.jpg
alt=“baz1” />’)

However the picture doesn’t show up, there’s just a broken link saying
‘baz1’.

Ok, here are the local logs and the production logs. While the local
logs
don’t have any errors the production logs are complaining about the line

  @character.profilepicture.save!

If you put that link straight into the browser you will see that
apparently amazon does not recognise websmash. I have never used
amazon aws so I can’t say exactly what the problem may be.

So open your S3 console and fix your permissions :slight_smile:

Ok, I’ve been reading about Amazon bucket ACLs and their permissions.
I’m
not clear on the following.
My objectives are simple: I have created a website in which users can
sign
in, make posts, upload photos etc. Firstly, which group should I choose
(Anyone; Any authenticated AWS user; log delivery; Me; Bazley). Which of
these represents “anyone signed in and using my website”?

Secondly, what level of permissions should I give this group? (Read;
Write;
Read_ACP; Write_ACP)

I apologise, I have been fiddling with my heroku apps. If you put the
link
straight into the browser you get this:
