I've been going over and over the Google documentation for GAE Python Blobstore:
https://developers.google.com/appengine/docs/python/blobstore/
and also some questions on the same
Google App Engine (Python) - Uploading a file (image)
Html form submit both datastore entity and blobstore through app engine
How to upload a file using the BlobStore in Python App Engine?
But I'm not able to get the file upload and input fields to pass all in a single form to be processed (code and errors below) and it's also not getting into the Blobstore.
newpost.html
<form method="post" action="/upload" role="form" enctype="multipart/form-data">
<div class="col-xs-6">
<div class="form-group">
<label for="title"><h2><small>Enter Title of this Post</small></h2>
<input type="text" name="subject" value="{{ subject }}" class="form-control">

<div class="pull-right">

class PixHandler(webapp2.RequestHandler):
def get(self):
upload_url = blobstore.create_upload_url('/upload')
## self.response.out.write('<html><body>')
## self.response.out.write('<form action="%s" method="POST" enctype="multipart/form-data">' % upload_url)
## self.response.out.write("""Upload File: <input type="file" name="file"><br> <input type="submit"

class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
upload_files = self.get_uploads('uploadFile') # from upload field in the form
blob_info = upload_files[0]
tag = '/pic/%s' % blob_info.key()
servePic = BlogPosts(imageTag = tag) # BlobStore entry
subject = self.request.get("subject")
content = self.request.get("content")
query = self.request.get("rname")
if (query):
self.render_query()
elif subject and content:
msg = "Looks good"
entry = BlogPosts(subject = subject, content = content)
entry_key = entry.put()
permalink = entry_key.id()
self.redirect("./%s" % str(permalink))
elif (not subject and not content):
msg = "Neither box can be empty"
self.render_html(subject, content, msg)
self.redirect(tag) # serves pix with unique id in url
class ServeHandler(blobstore_handlers.BlobstoreDownloadHandler):
def get(self, resource):
resource = str(urllib.unquote(resource))
blob_info = blobstore.BlobInfo.get(resource)
self.send_blob(blob_info)
HTTP error:
File "C:\Python27\udacity-web-app-rs-1\weblog.py", line 101, in post
blob_info = upload_files[0]
IndexError: list index out of range
It is not getting to the redirect page (going to HTTP error page). Also, the image key() is not getting into the Datastore value I set up for it
The handling is from the form to /upload using UploadHandler.
EDIT:
I realized some code was unrelated to these issues. Didn't change the question.
