I'm trying to upload fake image data using faker gem, but I am seeing this error:

Paperclip::AdapterRegistry::NoHandlerError: No handler found for ""

in db/seed.rb

5.times do 

in db/image.rb

    class CreateImages < ActiveRecord::Migration[5.2]
      def change
        create_table :images do |t|
          t.string :title
          t.string :filename



in db/add_attachment_item_image_to_images.rb (paperclip gem migration file)

Try with,


Your image must be in app/assets/images

or try following,, "app/assets/images/image.jpg"))

Common mistakes when storing file uploads with Rails, Saving files to a directory that is not shared between deploys or servers be delivered from a Rails controller action (e.g. /images/4/download ) by using send_file . See Always store your Paperclip attachments in a separate folder per environment makandra has been working exclusively with Ruby on Rails since 2007. Faker. This gem is a port of Perl's Data::Faker library that generates fake data.. It comes in very handy for taking screenshots (taking screenshots for my project, Catch the Best was the original impetus for the creation of this gem), having real-looking test data, and having your database populated with more than one or two records while you're doing development.

if FactoryGirl is your next option, you can use as follows in spec/factories.rb:

include ActionDispatch::TestProcess
FactoryGirl.define do
    factory :picture do 
      original_filename "test.jpg"
      file { fixture_file_upload(Rails.root.to_s + '/spec/fixtures/files/test.jpg', 'img/jpeg') }

Radiant - A no-fluff, open source content management system designed for DragonFly - A Ruby gem for on-the-fly processing - suitable for image uploading in Rails,  Faker gem serves to take this pain away by generating the fake data just as needed and saving us all the time and effort otherwise wasted in the manual process of data-generation. It can generate almost any kind of data suitable for our application.

Faker::Avatar.image('app/assets/image.jpg') returns a String with url to image placeholder (""), but Paperclip expects a file or IO there.

So you should pass something like, 'spec', 'fixtures', 'files', 'avatar.jpg')) (and place some image at that path)

Ruby Gems - My Favorite Ones, For those who do not have much time in Rails, Devise gives you everything us with the API client to upload the previous paperclip images to AWS S3, Faker. It is used to generate random data, such as names, surnames,  Since passing a file into the picture attribute works when passing a string (from Faker::Avatar.image) didn't, I'm guessing that the Picture model is using Paperclip (or some other file upload gem), and the picture setter expects to receive a file rather than a string.

Paperclip Gem, I'm using the paperclip gem to upload and display images for an object called "​item". People are listing Ruby as their most hated language. But how to use this feature to allow Rails Event Store data to be stored in a separate database? sudo apt-get install imagemagick --fix-missing. wont work. If that is your case, do. sudo apt-get update. first then install imagemagick after that

  • is multipart: true set in your form?
  • @nileshkumar lol, he is not creating it from form, it must be test data.
  • @ray: oh I see now :)
  • Try with Faker::Avatar.image('image.jpg') or Faker::Avatar.image("#{Rails.root}/app/assets/image.jpg")
  • hi ray,it not working.same error
  • 20.times do Image.create( item_image: Rails.root.join("app/assets/images/food_image1.jpg").open, filename: "food", title: "food" ) end it tryed this way it work,but it store only one img all time.
  • If you have 20 images then you can do like, 20.times do |n|; Image.create( item_image: Rails.root.join("app/assets/images/food_image#{n}.jpg").open, filename: "food", title: "food" )
