Hi everyone,

I’m trying to test file uploads (with attachment\_fu) in the  
integration tests for a rails 2.0.1 application, with code like:

post :action, :data =\> fixture\_file\_upload(‘/image.png’, ‘image/  
png’)  
assert\_response :redirect

but this fails with a message  
NoMethodError (undefined method `content\_type’ for  
“#ActionController::TestUploadedFile:0xb6f1a28c”:String):

because the TestUploadFile object is converted to a String with #to\_s  
in #requestify (integration.rb about line 337). Obviously,  
attachment\_fu shows this error but the string conversion problem is  
general.

I guess TestUploadedFile should be kept in the parameters hash as-is  
instead of being converted to #inspect-Strings.

I hope I’m doing something wrong (i.e. there is an argument to post  
that I’m missing).  
If not, shall it be specified in the documentation for  
fixture\_file\_upload that this does not work with integration tests?  
There has been a ticket about it for 2 years, now[1].
