I am having an issue with google app engine. I am trying to implement a Person ndb model that will store basic info on a person. When I try to query the database for a key though, I keep getting a Nonetype error in traceback:
File "xxxx", line 104, in get
parent = ndb.Key('Person', users.get_current_user().email())
AttributeError: 'NoneType' object has no attribute 'email'
Here is the code that relates to the error:
This is where I declare the model
class Person(ndb.Model):
dev_id = ndb.StringProperty()
num_readings = ndb.IntegerProperty()
And here I am simply trying to use it later in the same file:
class MainPageLI(webapp2.RequestHandler):
# Front page for those logged in
def get(self):
user = users.get_current_user()
parent = ndb.Key('Person', users.get_current_user().email())
person = parent.get()
if person == None:
person = Person(id=users.get_current_user().email())
person.temperature_unit = 'celsius'
person.time_zone = 8.00
"""person.notify_type = ['by-time']
person.notify_time_value = 4
person.notify_time_unit = 'days'
person.notify_parameters = ['by-temp']
person.notify_temperature_abe = 'exactly'
person.notify_temperature_value = 20
person.notify_temperature_unit = 'celsius'
person.notify_light_abe = 'above'
person.notify_light_value = 90
person.notify_motion = 'present'"""
person.num_readings = 5
#person.history_log_value = 2
#person.history_log_unit = 'days'
person.put()
if user: # signed in already
params = urllib.urlencode({'username':users.get_current_user().nickname()})
template_values = {
'user_mail': users.get_current_user().email(),
'logout': users.create_logout_url(self.request.host_url),
'nickname': users.get_current_user().nickname(),
}
template = jinja_environment.get_template('frontuser.html')
self.response.out.write(template.render(template_values))
else:
self.redirect(self.request.host_url)
NOTE: All the indenting is proper in the file, it just copy-pasted awkwardly (especially the MainPageLI segment, the first few lines are tabbed right in the file).
Any and all help would be greatly appreciated! thanks :)
You need to move your
if user: # signed in already
check higher up, before theusers.get_current_user().email()
call (which you can replace withuser.email()
BTW, since you already obtaineduser
above).
