Dynamic store dirs for same models with carrierwave

I am using CarrierWave with fog to upload my images to S3.

I have model Image that can represent images of different sizes and according to that needs to be saved in different folder.

For example, for image.jpg I could have two different uploaded versions that need to be saved as:

'images/large/image.jpg'
'images/small/image.jpg'

There could be arbitrary number of use cases and versions using minimagick can't cover them all.

So far I haven't been able to find solution. Does anyone know how to do this?

I've seen this question asked a few times so I'll write what my final solution is.

Instead of defining mount_uploader on model I decided to just use Uploader independently and save urls to records later.

Dynamically changing store_dir and filename can be accomplished like this

uploader = Uploader.new

uploader.define_singleton_method(:store_dir) do
    'new_store_dir'
end
uploader.define_singleton_method(:filename) do
    'new_filename'
end

uploader.store!(image)

Using this approach you can also define names with local variables or whatever you have available in controller.

Hopefully it helps someone else as well.

in order to change where uploaded files are put, just override the store_dir method:, for your case (reference link)

class Image < CarrierWave::Uploader::Base
storage :file
  # this if you using use condition for folder location
  def store_dir
    if model.somefield == "somecondition
       "uploads/#{model.somefield}"
    elsif model.somefield == "somecondition
       "uploads/location2"
    else
       "uploads/default_dir"
    end

  end
  # this is if you want to use version_name
  def store_dir
    'images/#{version_name}/'
  end
end
