I am attempting to make use of the google app engine to have a login system for a site I am building using Webapp2 in python. Upon attempting to access the root page however, I receive this error

The code section that it errors on is as follows:
class LoginHandler(webapp2.RequestHandler):
def get(self):
user = users.get_current_user()
myPage = """
<html>
<body>
<div>
<h2>Google App Engine Login - Python Web app</h2>
<h3>Welcome, {0}. This is a sample page!</h3>
<b>Click here to {2}</b>
</div>
</body>
</html>
"""
if user:
myData = myPage.format(user.nickname(), users.create_logout_url("/"),'logout' )
else:
myData = myPage.format('Guest', users.create_login_url("/"),'login' )
return myData
As Dan Cornilescu commented, setting the following environment variable fixes this
os.environ["AUTH_DOMAIN"] = 'gmail.com'

I'm trying to insert an instance of a model into an ndb database.
It keeps on giving me the "Model is not immutable" error.
I have tried with different model names, but still the same error.
class User(ndb.Model):
username = ndb.StringProperty()
email = ndb.StringProperty()
lwr_username = ndb.ComputedProperty(lambda self: self.username.lower())
lwr_email = ndb.ComputedProperty(lambda self: self.email.lower())
Here's my insert code:
entity = User()
entity.email = ""
entity.username = "bob"
logging.info(entity)
#Commit data asynchronously
entities = [entity]
futures = ndb.put_multi_async(entities)
#Build Response whilst database is committing
response = {
}
#Wait for commits to finish
ndb.Future.wait_all(entities)
This is the full stack trace
Model is not immutable

TypeError: Model is not immutable
You need to use the futures list, not entities to wait for the async process to complete:
ndb.Future.wait_all(futures)
The wait_all() function stores these in a set() object, and sets require the contents to be hashable. Since mutable objects cannot be stored in sets or dictionaries, Google engineers added an explicit TypeError to the Model.__hash__ method, which is what you see raised here.
this question has been asked before but found no answers that worked !
i am using urlfetch in my code to fetch url content but am getting unable to fetch URL error . Heres a part of my code :

i replaced the website name with the ipaddress but still the same error .
i am able to fetch data from the site using requests while testing locally in IDLE .
'http://103.4.253.46/search?q=nexus%204'
replacing space by %20 solved the error as suggested by #Back2Basics
I'm using google-api-python-client and imapclient libraries to try get IMAP access to Gmail.
When going through the authentication flow, I'm getting "invalid scope" errors. I've tried both https://mail.google.com and https://mail.google.com/mail/feed/atom as scopes.
Here's what I'm trying to do:
from oauth2client.appengine import OAuth2Decorator
SCOPE = "https://mail.google.com"
# SCOPE = "https://mail.google.com/mail/feed/atom"
oauth2decorator_gmail = OAuth2Decorator(client_id="CLIENT_ID",
client_secret="CLIENT_SECRET",
scope=SCOPE,
callback_path='/mycallbackurl')
class AuthenticateSyncServices(webapp2.RequestHandler):
#oauth2decorator_gmail.oauth_required
def get(self):
self.response.write("Authenticated")
And here's the stacktrace:

I have a problem, I want to access the data which are stocked in my google cloud storage but I have an error and I don't know where it comes from.

In your code you're listing the directory_structure bucket, but the traceback references jba_directory. There is a mis-match of some sort. Perhaps in a wrapping decorator or other code above the snippet you included here?
I'm new to Python (as well as GAE), I'm trying to include gaesessions in my application, this is exactly what I did:
I copied the gaesessions folder to my src folder (the folder includes __init__.py file)
and added this to my working code:
from gaesessions import get_current_session
session = get_current_session()
I received the following error:

You've omitted the actual exception from your stack trace, but I'm guessing it's this:
AttributeError: 'local' object has no attribute 'current_session'
If so, you've most likely skipped the middleware configuration step. Create an appengine_config.py per the instructions and restart the dev server; this should resolve your error.
