Uploading images to BlobInfo #78

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When sending image files via REST as a BlobProperty (using POST 
"/MyModel/<key>/<blobProperty>/content), I get a following error:

  File &quot;/home/mojmir/google_appengine/lib/webapp2-2.5.2/webapp2.py&quot;, line 1535, in __call__
    rv = self.handle_exception(request, response, e)

    dispatcher.request.body_file.getvalue())
AttributeError: 'LimitedLengthFile' object has no attribute 'getvalue'

Normaly, dispatcher.request.body_file is cStringIO.StringI object, but for some 
reason, it becomes LimitedLengthFile. I hacked it by replacing getvalue() 
method with read() method and it seems to be working now.

I have experienced the same problem, and fixed it the same way.  Specifically, 
I noticed this error when trying to add a single value to an indexed 
StringListProperty.
