Hi,

My app uses attachment\_fu and I’d like to pre-load some data via a rake  
task.

Thus:

[code]desc “Upload template files”  
task :upload\_files\_test =\> :environment do |t|  
conf = Conference.find(1)

[{:f =\> ‘styles.css’, :type\_code =\> ‘css’, :content\_type =\>  
‘text/css’}].each do |i|  
file =  
ActionController::TestUploadedFile.new(“db/migrate/widgets\_layout/” +  
i[:f], i[:content\_type])  
conf.conference\_files.create(:uploaded\_data =\> file)  
end  
end[/code]

But I get the rake error  
uninitialized constant ActionController::TestUploadedFile

If I start the console, ActionController::TestUploadedFile.new works  
fine.

_Thank you_ for any ideas,

Larry
