Rails ckeditor dragonfly Erorr - ruby-on-rails

Question

Gem => https://github.com/galetahub/ckeditor
Rails = 4.1.4
I've done
rails generate ckeditor:install --orm=active_record --backend=dragonfly
ckeditor_dragonfly.rb
# Load Dragonfly for Rails if it isn't loaded already.
require "dragonfly/rails/images"
# Use a separate Dragonfly "app" for CKEditor.
app = Dragonfly[:ckeditor]
app.configure_with(:rails)
app.configure_with(:imagemagick)
# Define the ckeditor_file_accessor macro.
app.define_macro(ActiveRecord::Base, :ckeditor_file_accessor) if defined?(ActiveRecord::Base)
app.define_macro_on_include(Mongoid::Document, :ckeditor_file_accessor) if defined?(Mongoid::Document)
app.configure do |c|
# Store files in public/uploads/ckeditor. This is not
# mandatory and the files don't even have to be stored under
# public. If not storing under public then set server_root to nil.
c.datastore.root_path = Rails.root.join("public", "uploads", "ckeditor", Rails.env).to_s
c.datastore.server_root = Rails.root.join("public").to_s
# Accept asset requests on /ckeditor_assets. Again, this is not
# mandatory. Just be sure to include :job somewhere.
c.url_format = "/uploads/ckeditor/:job/:basename.:format"
end
# Insert our Dragonfly "app" into the stack.
Rails.application.middleware.insert_after Rack::Cache, Dragonfly::Middleware, :ckeditor
But when I try to do something, an error:
Dragonfly::App[:ckeditor] is deprecated - use Dragonfly.app (for the default app) or Dragonfly.app(:ckeditor) (for extra named apps) instead. See docs at http://markevans.github.io/dragonfly for details
NoMethodError: undefined method `configure_with' for Dragonfly:Module
What ideas are there to solve the problem?
UPD. If correct these errors, it becomes:
Dragonfly::Configurable::UnregisteredPlugin: plugin :rails is not registered

Answer 1

Remove all ckeditor initializers.
Add new file with following content:
require 'dragonfly'
# Logger
Dragonfly.logger = Rails.logger
# Add model functionality
if defined?(ActiveRecord::Base)
ActiveRecord::Base.extend Dragonfly::Model
ActiveRecord::Base.extend Dragonfly::Model::Validations
end
Dragonfly.app(:ckeditor).configure do
# this generate path like this:
# /uploads/ckeditor/AhbB1sHOgZmIjIyMDEyLzExLzIzLzE3XzIxXzAwXzY0OF9zdXJ2ZWlsbGFuY2VfbmNjbi5wbmdbCDoGcDoKdGh1bWJJI.something.png
url_format '/uploads/ckeditor/:job/:basename.:format'
# some image from previous version can break without this
verify_urls false
plugin :imagemagick
# required if you want use paths from previous version
allow_legacy_urls true
# "secure" if images needs this
secret 'ce649ceaaa953967035b113647ba56db19fd263fc2af77737bae09d452ad769d'
datastore :file,
root_path: Rails.root.join('public', 'system','uploads', 'ckeditor', Rails.env),
server_root: Rails.root.join('public')
end
Rails.application.middleware.use Dragonfly::Middleware, :ckeditor
This will store image in (old style):
{Rails.root}/public/system/uploads/ckeditor/{development,production,etc...}

Eraden, your example works. I've replaced the contents of ckeditor_dragonfly.rb with what you've given and then "rake db:migrate" was finally successfull.
But then when I upload an image I get:
NoMethodError (undefined method ckeditor_file_accessor' for #<Class:0x007fb92c720118>):
app/models/ckeditor/asset.rb:5:in'
app/models/ckeditor/asset.rb:1:in <top (required)>'
app/models/ckeditor/picture.rb:1:in'
It seems, you need to replace "ckeditor_file_accessor :data" with "dragonfly_accessor :data" in /app/model/ckeditor/asset.rb. This solved this particular error for me, though I've got another one instead, but it seems to have nothing to do with the topic discussed.
(just for the case, I will write this problem here:
DRAGONFLY: validation of property format of data failed with error Command failed ('identify' '-ping' '-format' '%m %w %h' '/var/folders/x6/pwnc5kls5d17z4j715t45jkr0000gr/T/RackMultipart20150406-2109-1ho7120') with exit status and stderr dyld: Library not loaded: /usr/local/lib/liblzma.5.dylib
Referenced from: /usr/local/bin/identify
Reason: image not found
