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")

TypeError: 'bool' object is not subscriptable in Python3,odoo

I don't know where my problem is. Because years is char field must be string not bool.
I feel really frustrated. What can I do to fix this problem?
Any sort of help will be much appreciated!
Please give me some suggestions. Thanks!
Here is my code:
class HreDetailList(models.EcoModel):
_name = "hre.detail.list"
def _compute_holiday_flag(self):
for record in self:
record.work_on_holiday = False
now_year = int(record.years[:4])
next_year = now_year + 1
holiday_obj = self.env['hra.holiday']
holiday_data = holiday_obj.search([('holi_yy', 'ilike', next_year),
('holi_name', '=', 'Xmas')])
change_obj = self.env['hre.changedtl']
change_data = change_obj.search([('hre_empbas_id.emp_no', '=', record.emp_no),
('trans_flag', '=', True),
('lt_startdate', '=like', record.years[:4] + '%')])
for change_datadtl in change_data:
if change_datadtl.chg_kind == '6M' or change_datadtl.chg_kind == '6N' or change_datadtl.chg_kind == '6L':
if holiday_data.holi_date >= change_datadtl.lt_startdate and holiday_data.holi_date <= change_datadtl.lt_enddate:
record.work_on_holiday = True
break
else:
record.work_on_holiday = False
years = fields.Char(string='Year', size=7, required=True)
work_on_holiday = fields.Boolean(compute=_compute_holiday_flag, string='Work on holiday')
I am getting following error: TypeError: 'bool' object is not subscriptable:

Any ideas of what could cause this?

The problem was that I was working with a table object. user_client_association_table is a Table object, and I needed to specify a model to be updated. So I defined a model just for this:
from db import db
import model
class UserClient(db.Model):
__bind_key__ = "DEV_BASIS"
__tablename__ = "tb_user_client"
__table_args__ = {'extend_existing': True}
ctid = db.Column(db.Integer, primary_key=True)
And then I imported it:
from model import UserClient
...
#cognito_required
def put(self, stage: str):
data = Default.validator.parse_args()
table = user_client_association_table
db.session.query(UserClient).\
filter(table.c.client_id == data["client_id"]).\
filter(table.c.user_id == data["user_id"]).\
update({"is_default": 0})
db.session.commit()
return {
"data": {
"code": 200,
"message": f"The default user_id has been updated for the client {data['client_id']}",
}
}, 200
Really obscure problem here, thanks #snakecharmerb

Flask and JSON related

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:

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)
