FYI:I found a *GOTCHA* issue when upgrading to 1.92.3 from 1.77.3
Now you have to use .xml() on the URL() that you send into the GAE
API:
upload_url =
blobstore.create_upload_url(URL(r=request,c='default',f='upbm2gig_gaehandler',args=None).xml())
# This works
upload_url =
blobstore.create_upload_url(URL(r=request,c='default',f='upbm2gig_gaehandler',args=None))
# This crashes
It crashes because between 1.77.3 and 1.92.3, a change was made in
html.py in the URL() class.
Around html.py line 265, they added XML() around the return value.
return XML(rewrite.url_out(r or _request, env, application,
controller, function, args, other, scheme, host, port))
In 1.77.3 it was formerly:
return rewrite.url_out(r or _request, env,....)
So basically they have changed the signature of the URL() object.
Not very backward compatible, I would say...
