I want the user to be able to upload images to Google App Engine. I have the following (Python):
class ImageData(ndb.Model):
name = ndb.StringProperty(indexed=False)
image = ndb.BlobProperty()
Information is submitted by the user using a form (HTML):
<form name = "input" action = "/register" method = "post">
name: <input type = "text" name = "name">
image: <input type = "file" name = "image">
</form>
Which is then processed by:
class AddProduct(webapp2.RequestHandler):
def post(self):
imagedata = ImageData(parent=image_key(image_name))
imagedata.name = self.request.get('name')
imagedata.image = self.request.get('image')
imagedata.put()
However, when I try to upload an image, lets say "Book.png", I get the error:
BadValueError: Expected str, got u'Book.png'
Any idea what is going on? I have been working with GAE for quite some time, but this is the first time I had to use blobs.
I used this link: https://developers.google.com/appengine/docs/python/images/usingimages
which uses db, not ndb.
I also tried storing the image in a variable first like in the link:
storedInfo = self.request.get('image')
and then storing it:
imagedata.image = ndb.Blob(storedInfo)
Which ALSO gives me an error:
AttributeError: 'module' object has no attribute 'Blob'
Thanks in advance.
Had the same prob.
just replace
imagedata.image = self.request.get('image')
with:
imagedata.image = str(self.request.get('image'))
also your form needs to have enctype="multipart/form-data
<form name = "input" action = "/register" method = "post" enctype="multipart/form-data">
