Workaround for CarrierWave multiple file upload using sqlite3 in development

问题

In my team development environment, we are using sqlite3 which comes default in Rails.

However, carrierwave's implementation of multi files upload require database that supports array/json datatype.

Are there any workaround so that it will work on our development environment without installing other database such as postgres?

I'm following the instructions over here https://github.com/carrierwaveuploader/carrierwave#multiple-file-uploads

回答1:

The only possible workaround would be to create a separate model for the uploads:

class ImagesContainer
  has_many :uploads
end

class Upload
  mount_uploader :image, ImageUploader

  belongs_to ImagesContainer
end
