multiple mounts: ApplicationRecord instance "to_json" result is weird.

[ejvalmores]

I am trying to make an API only Rails app (Rails 5.0.1). In my Service model I have something like:

class Service < ApplicationRecord
   mount_uploaders :photos, ServicePhotoUploader
end

I noticed this issue while I was making the test script for my ServicesController. However, I managed to replicate it in the test environment console.

> service = Service.new()
> service.photos = [ Rack::Test::UploadedFile.new(File.join(Rails.root, 'spec', 'fixtures', 'images', 'altia.jpg')) ]
> service.save!
> service.to_json
=> "{\"id\":3053,\"photos\":[{\"url\":\"/uploads/service/photos/3053/altia.jpg\"}]}"

The result looks ok. But when I do service.reload the result looks weird.

> service.reload
> service.to_json
=> "{\"id\":3053, \"photos\":[{\"url\":\"/uploads/service/photos/3053/%5B%22altia.jpg%22%5D\"}]}"

Decoded, the 'url' value loooks like:

> URI.decode "/uploads/service/photos/3053/%5B%22altia.jpg%22%5D"
=> "/uploads/service/photos/3053/[\"altia.jpg\"]"

This is causing an issue when I to JSON.parse( respond.body ) in my test script.

Is this the expected result? or am I doing something wrong?

Thanks!

Not reproducible here, how does your uploader and test code look like?

Hi,

I can't replicate this in the latest version anymore.

Thanks!
