Hi!
I try to store a image in my google app engine application. I followed
this documentation:
http://code.google.com/appengine/docs/python/images/usingimages.html
My db.Model:
class Image(db.Model):
image = db.BlobProperty()
name = db.StringProperty()
My Form:
<p><form action="/insertImage" enctype="multipart/form-data"
method="post">
<p>Name:<br/><input name="name" type="text" size ="30"></p>
<p>Image:<br/><input name="file" type="file"/></p>
<div><input type="submit" value="Insert"></div></form></p>
My insertImage class:
class insertImage(webapp.RequestHandler):
def post(self):
name = self.request.get('name')
image = self.request.get('file')
setImage(name, image)
self.redirect('/')
def setImage(name, image):
dbm = MyDbModel.Image()
dbm.image = db.Blob(image)
dbm.name = name
dbm.put()
But after I click the "submit"-button of my online form I get this
error message:
google_appengine/google/appengine/api/datastore_types.py", line 1057,
in __new__
type(arg).__name__)
TypeError: Blob() argument should be str instance, not unicode
I also tried "dbm.image = db.Blob(open(image).read())" in my setImage
class. Which I found here:
http://code.google.com/appengine/docs/python/datastore/typesandpropertyclasses.html#Blob
But this result in this error:
google_appengine/google/appengine/tools/dev_appserver.py", line 1079,
in __init__
super(FakeFile, self).__init__(filename, mode, bufsize, **kwargs)
IOError: [Errno 2] No such file or directory: u'MyImage.jpg'
Do you have an idea what's wrong?
Thanks a lot!
Markus
