I have the following datastore model:
class FeatureCategory(db.Model):
name_eng = db.StringProperty(required=True)
name_spa = db.StringProperty()
name_por = db.StringProperty()
device_type = db.ReferenceProperty(DeviceType, required=True, collection_name='feature_categories')
class Feature(db.Model):
name = db.StringProperty(required=True)
category = db.ReferenceProperty(FeatureCategory, required=True, collection_name='features')
desc_eng = db.StringProperty()
desc_spa = db.StringProperty()
desc_por = db.StringProperty()
I've been experiencing errors when after doing a couple of db.get(db.Key('key_string')) and to the Referenced object like:
feats = dbmodel.Feature.all()
for feat in feats:
cat = feat.category
in the development environment. If I stop the server and restart, it will work for some queries and be back to throwing the error below. Any ideas how can I fix this?

I am new to flask and I am having some problems one of them being,
When I try to start running the below app on the server I get an error saying Attribute error: init
I have no clue what to do next even after a lot of googling.
from flask import *
from models import db, EmployeeModel
app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] = "sqlite:///theemp.db"
app.config["SQLALCHEMY_TRACK_MODIFICATIONS"] = False
db.init_app(app)
#Linking instance from Models and creating a DB file before the user accesses the server
#app.before_first_request
def create_table():
db.create_all()
#Create view
#app.route("/data/create", methods=["GET", "POST"])
def create():
if request.method == "GET":
return render_template("create.html")
if request.method == "POST":
employee_id = request.form["employee_id"]
name = request.form["name"]
age = request.form["age"]
position = request.form["position"]
employee = EmployeeModel(employee_id=employee_id, name=name, age=age, position=position)
db.session.add(employee)
db.commit()
return redirect(url_for("data"))
if __name__=="__main__":
app.run(debug=True)
Here is the exception I get.

The "ssl" library appeared to have issues with import, thus ssl = None.
Updating the app.yaml helped.

I have the following POST method in my api. After sending a big JSON collection around 350 entries to the api, I get an DeadlineExceedError exception.
I already am utilising the ndb.multi_put_async. I don't know what else I could do to speed this up?
def post(self):
arguments = self.reqparser.parse_args()
json_records = arguments.get('records')
user = User.query(User.email == request.authorization.username).get()
if user:
records_put_list = []
events_put_list = []
for json_record in json_records:
record_id = json_record['record_id']
rec = Record.get_or_insert(record_id,
user=user.key,
record_date=record_date,
timestamp=record_timestamp)
for json_event in json_record['events']:
event = Event.get_or_insert(json_event['event_id'],
parent=rec.key,
user=user.key,
is_deleted=json_event['is_deleted'])
if event.timestamp < json_event['timestamp']:
event.user = user.key
event.record = rec.key
event.date_time = event_dt
event.timestamp = json_event['timestamp']
event.parent = rec.key
events_put_list.append(event)
ndb.put_multi_async(records_put_list)
ndb.put_multi_async(events_put_list)
return '', 201
else:
return '', 401
This is the exception. Any advice what I could do?

You are not using the right logic. Do not put the get_or_insert in the loop - that is never going to work for anything except the smallest number of records (and is generally an anti-pattern to avoid). Instead create the entities and append them to the list inside the loop. Once this is done, the put_multi will then take this list and handle all the puts in parallel. There is a question about how many items in a put_multi list is tolerable, but 350 is far from what I remember as a limit.
You can use a Task API to split this processing job into smaller batches (e.g. 100 entries per task - you can find the optimum number).
I have to classes comment and report:
class comment(ndb.Model):
date =ndb.StringProperty()
title=ndb.StringProperty()
name=ndb.StringProperty()
content=ndb.TextProperty()
class report(ndb.Model):
comments=ndb.StructuredProperty(comment,repeated=True)
date=ndb.StringProperty()
title=ndb.StringProperty()
content=ndb.BlobKeyProperty()
images=ndb.BlobKeyProperty(repeated=True)
images_urls=ndb.StringProperty(repeated=True)
so i declare comments (in the report class) as ndb.StructuredProperty ,then when i get the comment from the user i append it to the comments in this way:
class add(webapp2.RequestHandler):
def post(self):
key_url=self.request.get("key")
key=ndb.Key(urlsafe=key_url)
report=key.get()
title=self.request.get("title")
name=self.request.get("name")
date=self.request.get("date")
content=self.request.get("content")
new_comment=comment(date=date,title=title,name=name,content=content)
report.comments.append(new_comment)
report.put()
self.redirect('/comments?'+urllib.urlencode({"key":key_url}))
actually when I deploy the project it is work fine, but after a while maybe 30 minute it fail , it is weird ! I get this error message:

You said when I asked if you had the class defined elsewhere - you said "yes actually i have , but i am sure that all of them are the same , i do copy paste"
There's your answer.
You should never define the class in more than one place, because if they are imported in different orders you will have problems when doing comparisons.
this is what the stack trace is telling you with

the classes for comment don't match
When building projects your should always adher to the principal of DRY (don't repeat yourself).
Put all your classes in one file and then import them where ever you need to use them.
In this case the validation routine is comparing the classes and whilst they may defined identically they are different entities.
