How to upload multiple files with cloudinary and carrierwave

I've been looking for a while at the Cloudinary documentation but can't figure out how to upload multiple files to it using Rails and a html form.

I added Cloudinary support to my Carrierwave ImageUploader

include Cloudinary::CarrierWave

and I added my api-key and secret to config/cloudinary.yml

but what more do I need to change? For now, I kept everything as it was with carrierwave. So my form holds a file field

<%=file_field_tag "images[]", type: :file, multiple: true %>

and then for every image a new picture instance gets created, and every picture instance holds a :image attribute

if params[:images]
     params[:images].each do |image|
           @post.pictures.create(image: image)
     end
end

I kept my ImageUploader more or less default.

class ImageUploader < CarrierWave::Uploader::Base

  include Cloudinary::CarrierWave
  storage :file
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end 
end

When I upload some images, the urls are linking to a cloudinary page, but nothing has been actually uploaded to cloudinary. Can I just add something to the create action of the picture controller to actually upload the image? Something like

def create
   @picture = Picture.new(picture_params)  
   @picture.save
   Cloudinary::Uploader.upload(picture_params)
end

The line of code where you upload your images would be good to see. You should have something like this: Cloudinary::Uploader.upload(your_image, auth) - The F
Sorry about that, I updated my question, but this line doesn't seem to upload it either - sjbuysse
You need to define your authorization params, that are needed for .upload as a second parameter. You should do that, and use .upload where you actually include Cloudinary::CarrierWave - The F
With authorization, do you mean the api key and secret? because that's defined in config/cloudinary.yml, so that should be allright. Also, I should I add the .upload to my ImageUploader then? - sjbuysse
Yes and yes - this sounds reasonable. feel free to also post some relevant parts of your uploader instead of your file field, which looks fine to me. - The F

Depending on the value of image, you could do this:

if params[:images]
  params[:images].each do |image|
    @post.pictures.create(image: image)
  end
  upload_images(@post.pictures)
end

def upload_images(images)
  images.each do |i|
    Cloudinary::Uploader.upload(i)
  end
end

Here's how it's done in Paperclip. 

class Attachment < ApplicationRecord
  if Rails.env == 'production'
    has_attached_file :file, :storage => :cloudinary, :path => ':class/:id/:filename', :cloudinary_resource_type => :raw


class Deal < ApplicationRecord
  has_and_belongs_to_many :attachments, dependent: :destroy
  accepts_nested_attributes_for :images, :attachments, reject_if: :all_blank, allow_destroy: true

  def files=(files)
    files.each do |file|
      attachments.build(file: file)
    end
  end

#controller
def deal_params
  params.require(:deal).permit :name, ...,  photos: [], files: [] 

#view
= form_for([parent, child], html: { multipart: true }) do |f|
  =f.file_field :files, multiple: true, class: 'form-control'
