   I am getting this error when viewing /upload. It comes up 5 times and the submit button does nothing.

   Here is the full text:
   

   File '/httpdocs/mediacore-0.8rc1/mediacore/lib/decorators.py', line 209 in validate
     return self._handle_validation_errors(args, kwargs, inv)
   File '/httpdocs/mediacore-0.8rc1/mediacore/lib/decorators.py', line 248 in _handle_validation_errors
     return error_handler(*args, **kwargs)
   File '/httpdocs/mediacore-0.8rc1/mediacore/controllers/upload.py', line 167 in submit_async
     response.headers['Content-Type'] = best_json_content_type()
   File '/httpdocs/mediacore-0.8rc1/mediacore/lib/helpers.py', line 515 in best_json_content_type
     desired_matches = mimeparse.desired_matches(
   AttributeError: 'module' object has no attribute 'desired_matches'

   Any ideas?

   Same debug message when attempting to "upload image".

   It looks like the mimeparse API has changed between Paste 1.7.2 (what we're running) and Paste 1.7.3 (what I'm assuming you're running). Since we don't explicitly state what version we require, Paste 1.7.2 has continued to be used on our deployments.

   For RC2 we're going to explicitly require the latest versions of all paste packages:

   • Paste 1.7.3.1
   • PasteDeploy 1.3.3
   • PasteScript 1.7.3

   Check back shortly for a patch.

   I am running Paste-1.7.3.1, PasteScript-1.7.3, and PasteDeploy-1.3.3

   I think explicit version numbers in setup.py are the way to go. Most of the problems with 0.7.2 were due to version mismatches (SQLAlchemy, Pylons, Routes). And now Paste...

   Thanks for the quick response.

   As it turns out, the best_json_content_type is was made unnecessary by porting from TG2 to Pylons 0.10rc1. I've committed a patch that removes the helper and simplifies the json header handling. If you're interested there's more info in the commit log:

   Respond to Flash uploads with header Content-Type: application/json

   Uploading files via Flash for Windows uses an Accept header of text/* and there's no way to override it. @expose('json') insists on returning a Content-Type of application/json.

   TurboGears2 can't cope with returning a Content-Type that doesn't match the Accept header. It doesn't throw a 403 Not Acceptable response, it dies with a 500 error. This logic was buried in controller code so extending wasn't a viable option. We decided to just return text/plain.

   Pylons 0.10 happily responds with application/json despite it not matching the Accept text/* header from Flash. To simplify things, we're taking advantage of this flexibility and returning application/json even though Flash didn't explicitly request it.

   This works fine but if we want to ensure we're returning acceptable headers at all times, we should improve the expose decorator rather than handling it in every controller that uses a Flash uploader.

   This also removes the need for the helper best_json_content_type, which relied on a mimeparse function that was removed in Paste 1.7.3.

   Uploads now work with both versions of Paste, but we'll still likely be updating setup.py to explicitly define the latest versions.
