blobstore redirects?

[pgio]

Anyone having success working with the blobstore? I'm correctly
generating upload URLs and getting data (images) into the blobstore,
but my handler for the uploaded blobs isn't working, instead
returning:

HTTP ERROR 500

Problem accessing /save. Reason:

Expected a redirect, tried to write content instead.

The function I'm using is this (and remember this is the Ringo request/
response):

exports.save = function save(req) {
var blob = blobstore.getUploadedBlobs(req);
res.status = ("303");
res.setHeader =("Location", "/serve?key=" + blob.file.toString())

return redirectResponse("/serve?key=" + blob.file.toString());
}

Doesn't seem to matter what I put in the function or try to return.
Any ideas?
Thanks,
Pete

perhaps Ringo's redirect sets the response body...

try something like (in JSGI parlance):

return {status: 303, headers: {}, body []} 

if you still have problems let me know, and I 'll give it a look...

Ringo's redirect does set the body; I tried with an edited
redirectResponse() with an empty body; same thing.
Tried the direct return like you suggested. Returns the same error.
There's also this in the trace if it helps:

SEVERE: TypeError: Cannot read property "jack.servlet_request" from
undefined (google/appengine/api/blobstore.js#53)
Script stack:
at google/appengine/api/blobstore.js:53 (anonymous)

I think the error is thrown already when
servletResponse.getOutputStream() is called, which is why it happens
even with an empty body. I just pushed a ringojs commit that might fix
this (depending on what appenginejs exactly does):

I pushed some changed that *may* fix the problem.
Also pull the latest version of Ringo.

Give it a try and let me know if it works...

I 'll better test it tomorrow.

Pulled down the newest ringo, built it. Tried to build a new appengine
app but that failed on copying ringo.jar (even though it was built and
sitting there). So I had to fix that by copying over the bin
directory. Tried to install appenginejs (missing zipball error) so I
pulled down that source and installed the package manually,
transferred over my app and static directories, and on appengine
startup I get a 503 Service Unavailable.

If I just take the latest version of blobstore.js and replace the old
one in the current version of the app, I get the same error I got
before about expecting a redirect.

Don't know if the contortions I had to go through led to that 503 or
what. Gonna back away from the computer now...

how did you try to install appenginejs?

OK, will update the appengine-blog-example with a blobstore example.

I 'll let you know when I have this ready.

OK,

it took a little bit longer than expected but the blobstore API is now
compatible with Ringo.

you can see a demonstration in the updated appengine-blog-example:

http://www.nitrojs.org/appenginejs/appengine-blog-example.tar.gz

let me know if it works for you now.

PS: you need to pull the latest ringo and run: ant jar

PS2: thanks to hannes for helping with this fix.
