factory_girl attachments for paperclip

# Paperclip attachments in factories, made easy based on technicalpickles
Factory.class_eval do
  def attach(name, path, content_type = nil)
    if content_type
      add_attribute name, ActionController::TestUploadedFile.new("#{RAILS_ROOT}/#{path}", content_type)
    else
      add_attribute name, ActionController::TestUploadedFile.new("#{RAILS_ROOT}/#{path}")
    end
  end
end

Factory.sequence :badge do |n|
  "name#{n}"
end

Factory.define :badge do |badge|
  badge.name         { Factory.next :badge }
  badge.active       { true }
  badge.description  { "You get this when you are awesome" }
  badge.tags         { "cool awesome" }
  badge.site         { |badge| badge.association(:site) }
  badge.attach       ( "image", "test/fixtures/flower.png", "image/png" )
end

For Rails 3, your gist actually doesn't work. After looking at the Rails code, this code works:

Factory.define :contacts_short_csv, :class => 'CsvFile' do |f|
  include ActionDispatch::TestProcess
  f.csv   { fixture_file_upload( 'files/contacts_short.csv.upload', 'text/csv') }
  f.account_id { 1 }
end

My model is

class CsvFile < ActiveRecord::Base
  include Paperclip
  has_attached_file :csv
end

The CSV file is actually under test/fixtures/files/ and since they are not real fixture data, but actual CSV data for testing the data import process, I had to rename them as .csv.upload otherwise Rails's test will try to populate the test databases with them (and fail miserably)

I'm using Rails 3b4, with latest paperclip 61f74...eed69-master

You can simplify further by just adding "include ActionDispatch::TestProcess" to test_helper.rb, and then just using the following in your factory

f.field_name { fixture_file_upload 'filename', 'mimetype' }

I realize this is a pretty old post, but wasn't sure if anyone here has run into an issue when using S3 for storage. I'm using the code mentioned by sr3d, but am getting AWS::S3::RequestTimeTooSkewed in my test results when attempting to use a factory that contains an "upload" file.

Dont work for Rails 4.1
