If someone (like me) finds this later, I was able to achieve this without adding this helper, and instead having capybara attach like so:

attach_file(@basic_file, class: 'dz-hidden-input', make_visible: true)

Test Dropzone.js File Uploads With Capybara
Dec 29, 2014

Integration tests involving complex JS interactions are a pain, especially with something like drag and drop file uploads (you can’t exactly drag something into a headless browser). My recent use case was an AngularJS application using Dropzone.js with Ruby on Rails on the backend, so I needed a way to make Dropzone play nicely with Capybara Webkit. Here is the spec helper I ended up with:

def drop_in_dropzone(file_path)
  # Generate a fake input selector
  page.execute_script <<-JS
    fakeFileInput = window.$('<input/>').attr(
      {id: 'fakeFileInput', type:'file'}

    # find all models and group them on keys which should be common
    grouped = all.group_by{|model| [model.title,model.info,model.address,model.phone] }
    grouped.values.each do |duplicates|
      # the first one we want to keep right?
      first_one = duplicates.shift # or pop for last one
      # if there are any more left, they are duplicates
      # so delete all of them
      duplicates.each{|double| double.destroy} # duplicates can now be destroyed
    end

(wherever it says url.com, use your server's domain or IP)

Login to new server as root, then add a deploy user

sudo useradd --create-home -s /bin/bash deploy
sudo adduser deploy sudo
sudo passwd deploy

And Update the new password
