I have an upload page for uploading multiple mp3 files using
uploadify.
For me it works perfectly, however one of my users reports
intermittent problems, and indeed, errors appear in the logs.
My set up:
Rails 2.3.5 + datamapper 0.10.2, latest uploadify, Ruby EE 1.8.7
2009.10, passenger 2.2.9
Here is a successful uploadify post from the user:
Processing Media::Lessons::DaysController#create (for x.x.x.x at
2010-01-20 12:59:16) [POST]
Parameters: {“Filename”=>“20100124_sun.mp3”,
“_chronicles_session”=>"…blablabla…", “folder”=>"/media/lessons/
days/", “action”=>“create”,
“authenticity_token”=>"…moreblablabla…", “Upload”=>“Submit Query”,
“fileext”=>"*.mp3", “controller”=>“media/lessons/days”,
“Filedata”=>#<File:/tmp/RackMultipart20100120-4207-dnd6as-0>}
Completed in 1125ms (View: 1 | 200 OK
And here is a failed one:

I have looked at methodoverride.rb but I don’t really get what’s going
on.
The error occurs here (methodoverride.rb line 15):
def call(env)
if env[“REQUEST_METHOD”] == “POST”
req = Request.new(env)
method = req.POST[METHOD_OVERRIDE_PARAM_KEY] || #<--------
line 15
env[HTTP_METHOD_OVERRIDE_HEADER]
method = method.to_s.upcase
if HTTP_METHODS.include?(method)
env[“rack.methodoverride.original_method”] = env
[“REQUEST_METHOD”]
env[“REQUEST_METHOD”] = method
end
end
@app.call(env)
end
Anyone have any ideas?
The error persists with all versions of passenger I have tried (2.2.4
to 2.2.9)
Thanks,
