attachment_fu functional testing

Hi,

I'm trying to write a functional test to a model that has attachment_fu:

{{{   fdata = fixture_file_upload(fname,'application/octet-stream')   post url_for(:controller=>:support_files, :action=>:create),     :session=>session, :project_id=>project_id, :support_file=>{'uploaded_data'=>fdata}, :format=>'xml' }}}

The log file shows: {{{ NoMethodError (undefined method `content_type' for "#<ActionController::TestUploadedFile:0x4376938>":String):     /vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb: 255:in `uploaded_data='     c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/base.rb:1672:in `send'     c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/base.rb:1672:in `attributes='     c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/base.rb:1671:in `each'     c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/base.rb:1671:in `attributes='     c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/base.rb:1505:in `initialize_without_callbacks'     c:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/callbacks.rb:225:in `initialize' }}}

The strange this is, when it runs with file updates from a browser, this all works just fine.

Any ideas?

Thanks, Helzer

Your fdata needs to be an object which acts like an uploaded file.

IE:   MockFile = Struct.new( :original_filename, :read, :content_type )   fdata = MockFile.new :original_filename=>"filename", :read=>"data", :content_type=>"text/ html"

If you use Mocha or another mocking library you can do:

  fdata = mock()   fdata.expects( :original_filename ).returns( "somefilename" )   fdata.expects( :read ).returns( "file contents" )   fdata.expects( :content_type ).returns( "text/html" )

HTH,
