I have these two models:

### User ###
############
class User(ndb.Model):
fb_id = ndb.StringProperty(indexed = True, required = True)
fb_access_token = ndb.TextProperty(indexed = False, required = True)
email = ndb.StringProperty(indexed = True, required = True)
first_name = ndb.StringProperty(indexed = False, required = True)
last_name = ndb.StringProperty(indexed = False, required = True)
gender = ndb.StringProperty(indexed = False)
group_key = ndb.KeyProperty(indexed = False, required = False, kind = Usergroup, default = ndb.Key(Usergroup, 'member'))
join_date = ndb.DateTimeProperty(indexed = True, auto_now_add = True)
last_login = ndb.DateTimeProperty(indexed = True, auto_now_add = True, auto_now = False)
#app.route('/user/login', methods=['POST'])
def user_login():
me = exchange_token_me(request.form['accessToken'])
if me is not False:
user = user_find_or_register(me)
if user is not None:
register_session(user)
return 'success'
return 'error'
def user_find_or_register(user):
qry = User.query(User.fb_id == user['id'])
existing_user = qry.get()
if existing_user is not None:
existing_user.fb_access_token = user['access_token']
existing_user.fb_id = user['id']
existing_user.email = user['email']
existing_user.last_login = datetime.datetime.now()
existing_user.put()
return existing_user
new_user = User()
new_user.fb_id = user['id']
new_user.fb_access_token = user['access_token']
new_user.email = user['email']
new_user.first_name = user['first_name']
new_user.last_name = user['last_name']
new_user.gender = user['gender']
new_user.last_login = datetime.datetime.now()
#new_user.group_key = ndb.key(Usergroup, 'member')
key = new_user.put()
saved_user = key.get()

session['loggedin'] = True
The Usergroup model has a small unique string as entity key. There is already a Usergroup whose key is 'member'
Whenever we create/save a user, it should use the key to the 'member' usergroup, but we get this error instead:
TypeError: Key('Usergroup', 'member') is not JSON serializable

UPDATE:
After Dan has spotted the problem, the solution is in the following function:
def register_session(user):
session['fb_id'] = user.fb_id
session['first_name'] = user.first_name
session['last_name'] = user.last_name
session['group_key'] = user.group_key.id() # Thanks Dan
session['loggedin'] = True
FWIW, a quick test with your code as models.py shows this to be working just fine, at least on the development server:
from models import User
user = User(email='email', username='username')
user.put()
produced:
This worked without even having a Usergroup entity - a key can exist without a matching entity. Of course, trying to follow the link to the Usergroup in the datastore viewer fails:

So you might want to show your actual code creating the entity and the full traceback, something else may be going on.
Your traceback indicates that the problem is not with creating the entity, but with saving your session:
File "/var/www/mywebsite/public_html/lib/flask/app.py", line 926, in save_session
return self.session_interface.save_session(self, session, response)
It appears you included in the session content the key object (possibly by including the entire User entity?), which is what causes the failure. For that purpose keys need to be serialized and you can use key.urlsafe() for that. See this answer for an example: https://stackoverflow.com/a/34835074/4495081
If indeed you included the entire User entity in the session you can just include its urlsafe key instead.
Yup, this is the source of your problem:
session['group_key'] = user.group_key
change it to:
session['group_key'] = user.group_key.urlsafe()
And you'll retrieve it like this:
urlsafe_key = session.get('group_key')
if urlsafe_key:
group_key = ndb.Key(urlsafe=urlsafe_key)

I have a function that exports a CSV to S3:
def export_csv(report_id):
# MyModel has a JsonField called `json_data`
items = MyModel.objects.all()
data = [x.json_data for x in items]
df = pd.DataFrame(data)
file_buffer = io.StringIO()
# QUOTE_ALL to avoid separators from throwing off columns
df.to_csv(
file_buffer,
index=False,
encoding='utf-8',
quotechar='"',
quoting=csv.QUOTE_ALL,
)
report.report_data_file.save(
"data.csv", ContentFile(file_buffer.getvalue())
)
I'm using the following FieldField:
class PrivateMediaStorage(S3Boto3Storage):
location = settings.AWS_PRIVATE_MEDIA_LOCATION
default_acl = 'private'
file_overwrite = False
custom_domain = False
class Report(BaseModel):
...
report_data_file = models.FileField(
storage=PrivateMediaStorage(),
upload_to=export_location,
null=True,
blank=True,
)
This is working fine in my local environment, where PrivateMediaStorage is defined as
class PrivateMediaStorage(FileSystemStorage):
pass

When I do print("major_id: " + str(user.major.id)) it will print major_id: 5b55e986f15bf336e0b820fe to console. Why does str(user.major.id) seen as bytes type in jsonify? I've tried to delete 'major_id': str(user.major.id) but then line 'token': token will cause the same error.
Thank you.
It seems that your data may not be properly decoded. You could try to decode your data before jsonifying it.
For example, instead of using token directly, try using: token.decode('utf-8')
I'm studying Flask and now want to dump some data to json and print a piece of data to the web:
#app.route('/home')
def index():
if 'piece' in session:
m = session['piece']
session.clear()
# online_users = mongo.db.GOOG.find({'date': '2017-02-01'})
return render_template('index.html')
#app.route('/query', methods=['POST'])
def query():
# stockName = request.form['stockName']
print(request.json)
stockName = request.json['stockName']
stock = mongo.db[stockName]
m = stock.find({})
session['piece'] = m.clone()
mClone = m.clone()
docs = []
for doc in m:
one = json_util.dumps(doc, default=json_util.default)
docs.append(one)
docs = json_util.dumps(docs)
print type(docs)
s = str(mClone[4][u'high'])
print s
return s
the output is:

I'm a bit curious about the error. It's like happening between print s and return s. Or would it be possible that after the post of query, /home is loaded again, but in this case, s should be returned to my web page.
Solved.
Seems session will excute by the end of the function, and m has been iterated, thus error appears.
Don't know if this explains correctly.
At first you need from flask import jsonify.
print type(docs)
s = str(mClone[4][u'high'])
print s
return jsonify({data: s})
here is the flask documentation link with an example:
http://flask.pocoo.org/docs/0.12/patterns/jquery/
I have an application that has worked successfully in the past. Today however, it's started throwing an error when I try write to datastore. For example, I'm creating a new entity of this model
class EventInstallment(ndb.Model):
somekey = ndb.KeyProperty()
somename = ndb.StringProperty(default = "")
start_date = ndb.DateTimeProperty()
notes = ndb.StringProperty("")
moderator_approved = ndb.BooleanProperty(default = True)
added_by = ndb.KeyProperty()
created = ndb.DateTimeProperty(auto_now_add = True)
using this code
ins = somemodel()
ins.somename = "26-september-2016"
ins.somekey = the_key
ins.start_date = datetime.datetime.now()
ins.put()
and this exception gets thrown.

Any idea what this issue might be? It looks like a change in GAE ndb - as it worked as recently as 1 month ago...
Shouldn't notes = ndb.StringProperty("") be: notes = ndb.StringProperty(default = "") ?
Hi i am getting error on this line. Its working in local.
I just deleted all the entities at appspot.
#query line
sent_list = db.GqlQuery("SELECT email FROM MailListNew WHERE active = True")
#error line
sent_count = sent_list.count()
projection and keys_only cannot both be set

You need to change the query to:
sent_list = db.GqlQuery("SELECT * FROM MailListNew WHERE active = True")
or (better):
sent_list = db.GqlQuery("SELECT __key__ FROM MailListNew WHERE active = True")
