I'm stuck at a point to implement the upload function in my web application using GAE. After submitting at /signup page, it redirects to /upload_file page, while it prompts the error 405 Method Get not allowed, and I was expecting to see the upload form.
(Got some Reference from: https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/appengine/blobstore/main.py)
Appreciate any help!
Part of the code in a main python script:
# BaseHandler is a subclass of webapp2.RequestHandler.
# create an upload URL for the form that the user will fill out
upload_url = blobstore.create_upload_url('/upload_file')
self.render('upload-file.html', upload_url = upload_url)
upload = self.get_uploads('file') ## 'file' is a var in the upload-file.html
blob_key = upload.key()
blob_reader = blobstore.BlobReader(blob_key) # instantiate a BlobReader for a given BlobStore value.
locations = parsefile(blob_reader)
img_url = generate_url(locations=locations)
self.redirect('/view_map/%s' % img_url)
app = webapp2.WSGIApplication([('/', Home),
After submitting at /signup page, it redirects to /upload_file page, while it prompts the error 405 Method Get not allowed, and I was expecting to see the upload form.
I think herein lies the problem. After sign up you're redirecting to
/upload_file page which is mapped to
FileUploadHandler, as follows:
('/upload_file', FileUploadHandler),. Now note that
FileUploadHandler has no get method to handle your redirect.
What I reckon you wanted to achieve is to render your
upload_file template(which contains your upload form) after signup and you already have the logic setup in
class FileUploadFormHandler. So you should instead map the
/upload_file route to
Also you will need a route to handle the call to your
FileUploadHandler when creating the upload url for the form the user will fill.
class FileUploadFormHandler(BaseHandler): def get(self): upload_url = blobstore.create_upload_url('/upload') self.render('upload-file.html', upload_url = upload_url) ... ... app = webapp2.WSGIApplication( [..., ('/upload', FileUploadHandler), ('/upload_file', FileUploadFormHandler), ... ], debug=True)
NOTE: You should probably come up with less confusing url paths ;)
