Feature: Running paperclip in a Rails app
Scenario: Basic utilization
Given I generate a rails application
And I have a "users" resource with "name:string"
And I run "script/generate paperclip user avatar"
And I save the following as "app/models/user.rb"
"""
class User < ActiveRecord::Base
has_attached_file :avatar
end
"""
And I save the following as "app/views/users/new.html.erb"
"""
<% form_for @user, :html => { :multipart => true } do |f| %>
<%= f.text_field :name %>
<%= f.file_field :avatar %>
<%= submit_tag "Submit" %>
<% end %>
"""
And I save the following as "app/views/users/show.html.erb"
"""
<p>Name: <%= @user.name %></p>
<p>Avatar: <%= image_tag @user.avatar.url %></p>
"""
And this plugin is available
And the rails application is prepped and running
When I visit /users/new
And I fill in "user_name" with "something"
And I attach the file "test/fixtures/5k.png" to "user_avatar"
And I press "Submit"
Then I should see "Name: something"
And I save and open the page
Given %r{I generate a rails application} do
FileUtils.rm_rf TEMP_ROOT
FileUtils.mkdir_p TEMP_ROOT
Dir.chdir(TEMP_ROOT) do
`rails _2.3.8_ #{APP_NAME}`
end

end

FileUtils.mkdir_p(File.join(CUC_RAILS_ROOT, File.dirname(path)))
File.open(File.join(CUC_RAILS_ROOT, path), 'w') { |file| file.write(string) }
end
