Hi,

I’m trying to do integration tests that require uploading files via  
multipart posts.

Have seen a very similar discussion, but cannot get it to work. Maybe,  
it’s out of date now with Rails 1.2.3:  
[http://groups.google.ca/group/rubyonrails-talk/browse\_thread/thread/fdfd2c040a2425f4](http://groups.google.ca/group/rubyonrails-talk/browse_thread/thread/fdfd2c040a2425f4)

Again, it doesn’t work. The file I’m getting is a truncated version of  
the original.

This is my code:

fdata = fixture\_file\_upload(fname,‘application/octet-stream’)  
multipart\_post  
url\_for(:controller=\>:support\_files, :action=\>:create),  
:session=\>session,  
:project\_id=\>project\_id,  
:support\_file=\>{‘uploaded\_data’=\>fdata},  
:format=\>‘xml’

BTW: On the other side, I’m using acts\_as\_attachment to process the  
multipart data. It works fine when I’m using a browser to upload.

Any recommendations on how to get this to work in an integration  
testing environment?

Thanks,  
Helzer

A quick update, if anyone’s interested:

The solution, shown in the ticket below, actually works fine AFTER I  
fixed the file read to open in mode ‘rb’ and not ‘r’.
