Attachment_fu functional testing

Rails
1

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:inuploaded_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:inattributes=’
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:inattributes=’
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:ininitialize’
}}}

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

Any ideas?

Thanks,

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,
