Okay, nobody in rails communication try to let rails follow RFC 2388. I won''t use rails anymore. It''s sucks!

There seems to be a problem with the implementation of the form by the testing software.

But.... as far as I can rationalise: Multipart data has to be turned into something... if you post a mix of text fields and files, if one of those files is a text file, both content-types would be "text/plain", so how would a server know which started on the form as a file-field and which was a text-field? It strikes me that the developers have to make assumptions, and it seems that a sensible assumption is that if a user-agent sends a multipart form; those elements without content-type (seeing as part of the RFC *does* say they''re optional) are form fields, and those with it are files. It also strikes me that since every browser (or at least the dozen or so I''ve tested it with) seems to post multipart forms *without* content-type for fields, this may be a common conclusion, and if one testing application goes the other way, and sends up ambiguous data (is it a text field, or a text file?) while expecting to get the right thing back; using Occams Razor, can it be that favourable that all the other browsers and frameworks are wrong?

I quote : "In the case where a field element is text, the charset parameter for the text indicates the character encoding used." I don''t know how the server distinguishing if the data is text or text- file, though.> It strikes me that the developers have to make assumptions, and it > seems that a sensible assumption is that if a user-agent sends a > multipart form; those elements without content-type (seeing as part of > the RFC *does* say they''re optional) are form fields, and those with > it are files. > It also strikes me that since every browser (or at least the dozen or > so I''ve tested it with) seems to post multipart forms *without* > content-type for fields, this may be a common conclusion, and if one > testing application goes the other way, and sends up ambiguous data > (is it a text field, or a text file?) while expecting to get the right > thing back; using Occams Razor, can it be that favourable that all the > other browsers and frameworks are wrong?Yes, as you mentioned, posting multipart forms *without* content-type (and character encoding if it''s text) for fields may be a common conclusion. But since it''s *optional*, I think, it could be (and could not be) there..... Anyways, I got through my problem, so I don''t care at this time. BTW, thanks for your reply.
