Re: [google-appengine] Re: Blobstore file upload with other form values

2011-02-13 Thread Robert Kluin 
Hi,
  You're getting the IndexError because get_uploads is returning an
empty list, which means there are no blob-info records for the 'file'
field.

  Your other error is because BlobstoreUploadHandler only allows
redirects.  Like Doug suggests, you'll need to redirect to another
page to output something.

 I think your issue is that you lose your self.response.out.write(N)
 content when you redirect via return self.redirect('/')... that
 response body content won't survive the redirect (the redirect will
 provide its own content).  If you need to return the submitted N and S
 content then perhaps you could redirect to a URL that takes the 'a'
 object key as a parameter self.redirect('/' +
 urllib.quote(a.key())).  Of course you'd have to setup your handler
 to accept the parameter... but then you could re-retrieve 'a' object
 in the handler via a datastore get such as a = db.get(a_key)...
 assuming 'a_key' is the name of the parameter.

Thank you. I solved the problem. In my html form I forgot to put
enctype=multipart/form-data. It seems working now.

[google-appengine] Re: Blobstore file upload with other form values

2011-02-12 Thread Doug Anderson 
FWIW I'm facing the same problem and I'm reasonably certain the issue is 
simply a limitation of the BlobstoreUploadHandler.  The handler stores 
uploaded blobs perfectly fine and gives your handler the BlobInfo for each 
blob BUT it seems to discard any non file (type='file') form fields.  So if 
you want to upload a text description along with a photo you're out of luck 
(using the blobstore).  I don't actually want the text description stored in 
the blobstore but I'd like it passed to the handler so I can store it in the 
datastore.

PLEASE FIX this blobstore upload issue... please make other (non file) form 
fields available to BlobstoreUploadHandler derived classes.  Thank you!

On a separate note I'm really looking forward to the programmatic access to 
the blobstore that I see listed on the roadmap!

As I understand from it, It could not get the file so it gives list
index out of range error. However, in another application I use the
same structure and it does not give any error.

Any suggestion about that?

 Some thoughts / suggestions:
   1) Check your url to handler mappings. Both in app.yaml and in your
 WSGI app definition.
   2) Check the logs to see what urls are actually getting hit.
   3) At some point in the Upload handler you do create and put a new
 Expert entity, right?

  Hello,

  I have a structure like:

         S = db.StringProperty(indexed=True, required=True,

                 upload_url = blobstore.create_upload_url('/upload')
                 doRender(self, addexpert.htm, {'upload_url': upload_url } )

  and html form like:

  form id=upload_form action={{ upload_url }} enctype=multipart/
  form-data method=post
  table
   trtd class=leftcolumnName/tdtdinput type=text
  name=name //td/tr
   trtd class=leftcolumnSurname/tdtdinput type=text
  name=surname //td/tr
  

  when I tried to upload my data and redirect my page:

  class Upload(blobstore_handlers.BlobstoreUploadHandler):
     def post(self):
         upload_files = self.get_uploads('file')
         blob_info = upload_files[0]
         blob = blob_info.key()
         N = self.request.get('name')
         S = self.request.get('surname')
         ..
         self.redirect('/')

  It redirects to an empty page. It saves the file at __BlobInfo__ (I
  could see it at SDK console) but it does not save other information.

  Am I missing any point?
  Thanks for helps in advance.
