Invalidate cache in CarrierWave uploader?

[sandric]

Hi, I having strange issue that I found many people struggle with through out issues, but I havent found how to make it using carrierwave. My problem is that if I have cloudinary carrierwave uploader on field in model and currently that field is nil and I upload new image using just simple_form form submit - it appears in cloudinary dashboard and as actual field in model so I can see uploaded image on site. Issue occurs when I want to update existing image on model - after model.update_attributes call with say logo parameter from form submitted, I see new image occurs in dashboard and old one is gone, however, my model still having old image in its field, so that I see only old image on site.

For example, my model Comany is Neo4j one, and in it is only that:

class Company
  ...
  property :logo
  mount_uploader :logo, CompanyLogoUploader
  ...
end

CompanyLogoUploader:

class CompanyLogoUploader < CarrierWave::Uploader::Base
  include Cloudinary::CarrierWave

  process :convert => 'jpg'

  if Rails.env.development?
    process :tags => ['env.development']
  end

  version :large do
    process :resize_to_fit => [500, 500, :north]
  end

  version :medium do
    process :resize_to_fit => [140, 140, :north]
  end

  version :small do
    process :resize_to_fit => [80, 80, :north]
  end

  version :tiny do
    process :resize_to_fill => [20, 20, :north]
  end
end

Now, if I have company model without logo and upload new one, all is great and here what I see as logo:

[2] pry(main)> Company.find('f0cfdf56-0f72-4184-affb-b37ee5fe097e').logo
=> #<CompanyLogoUploader:0x0055971c014d58

   @resource_type="image",
   @storage_type=nil,
   @uploader=#<CompanyLogoUploader:0x0055971c014d58 ...>,
   @version=nil>,
 @model=

[3] pry(main)> Company.find('f0cfdf56-0f72-4184-affb-b37ee5fe097e').logo.url(:medium)
=> "https://res3.cloudinary.com/davsupw1h/image/upload/c_fit,h_140,w_140/spikbsjvpx9tkgi78c3w.jpg"

It appears in dashboard with url: "https://res.cloudinary.com/davsupw1h/image/upload/v1532952671/spikbsjvpx9tkgi78c3w.jpg"

Now, If I'll change this image to smth else, here's updated debug:

[5] pry(main)> Company.find('f0cfdf56-0f72-4184-affb-b37ee5fe097e').logo.url(:medium)
=> "https://res-3.cloudinary.com/davsupw1h/image/upload/c_fit,h_140,w_140/spikbsjvpx9tkgi78c3w.jpg"

Whereas new image that got updated in dashboard has url "https://res.cloudinary.com/davsupw1h/image/upload/v1532953062/spikbsjvpx9tkgi78c3w.jpg" - version is changed.

So my question is next - should I pass version somehow in image uploader, and how/where?
If yes then why does carrierwave integration by default does not using version and rely on caching? Can I turn it off somehow, in uploader, in cloudinary initializer? Thanks.

[sandric]

Any ideas?

Hi @sandric. We've identified the issue - version remains nil after the update instead of been populated with the new version.
We'll update as soon as we'll have an ETA for a fix.

[sandric]

Any progress on this? I guess there should be fairly simple in-place fix untill pr with real fix is merged maybe?

[roeeba]

Hi @sandric, no ETA yet as we're still reviewing the issue and possible solutions. We'll update on any progress done.
