Testing Paperclip - post :create fails

I have a video model using Paperclip to store the file. The model:

class Video < ActiveRecord::Base   belongs_to :category   before_save :permalink

  validates_presence_of :title   validates_presence_of :category   validates_attachment_presence :filepath, :message => '- please, select a file to updload'   validates_attachment_size :filepath, :less_than => 100.megabytes   validates_attachment_content_type :filepath, :content_type => ['video/x-flv'],                                            :message => '- You can upload only Flash movies'

  has_attached_file :filepath,                     :url => APP_CONFIG['url']+"/videos/inline/:id",                     :path => ":rails_root/ uploads/:attachment/:id/:style/:basename.:extension"

  named_scope :videos_in_category,     lambda { |category_id|       {:conditions => ["category_id = ?", category_id]}       }

  private     def permalink       slug = Slug.new       self.url_slug = slug.url_friendly self.title     end end

When I run this test:

  test "should create video" do     assert_difference('Video.count') do       video = videos :videos_002       video.filepath = File.new("#{RAILS_ROOT}/test/fixtures/ add_file.flv")       video.filepath_content_type = 'video/x-flv'       category = categories(:intranet_administration)       post :create, :video => { :title => video.title,                                 :description => video.description,                                 :category_id => category.id,                                 :filepath => video.filepath,                                 :filepath_file_size => File.size("#{RAILS_ROOT}/test/fixtures/add_file.flv"),                                 :filepath_content_type => 'video/x- flv',                                 :url_slug => video.url_slug}     end

    assert_redirected_to video_path(assigns(:video))   end

I get this message:

"Video.count" didn't change by 1. <2> expected but was <1>.

I tried to understand why it is not created but I do not get any feedback. Do you have an idea how to solve this?

Thanks.

Any idea how to debug?

Just i noted from your code you are not using

"belongs_to :attachable" in your model video.

I will have a look thank you.
