Binance API get_aggregate_trades combination of optional parameters inavild - binance

I'd like to request aggregated trade data beginning at a certain timestamp until now
client.get_aggregate_trades(symbol = 'EURBUSD', startTime = 165605516493)
but i only get an Error:
File "c:\Users\Pascal\Python Skripts\Binance\test.py", line 39, in

binance.exceptions.BinanceAPIException: APIError(code=-1128): Combination of optional parameters invalid.
Even if i input all possible parameters (start and end time less than 1 hour), it still throws the same Error. What am i missing here?
Thank you a lot for helping.

I had the same problem.
I fixed it by adding an "endTime" parameter to the "get_aggregate_trades".
client.get_aggregate_trades(symbol='BTCUSDT', startTime='1534130155000', endTime='1534130169000')

I am trying to get account information, specifically my USDT balance to calculate the percentage (%) and I get the following error:

I have made different modifications and nothing has worked for me yet so that my code runs normally.
Check:
account_info = binance_client.futures_account()
amount = percent_amount * account_info['balance']
With this I try to obtain the balance to calculate the amount with which it will enter the operation based on % of the account, I need help

google.api_core.exceptions.FailedPrecondition: 400 no matching index found

I need to fetch data from google cloud datastore using python, when fetching all the collection it succeed, but when try to fetch specific value according to the key it failed, I provide the store data method and fetch data method:
def store_data(name, value):
entity = datastore.Entity(key=datastore_client.key('visit', name))
entity.update({
'name': name,
'value': value
})
datastore_client.put(entity)
def fetch_name(name):

print("name is: " + name)
# query.add_filter("name", "=", name)
results = list(query.fetch())
# print("GET - param is results: " + results)
return jsonify(results)
which mean, if I uncommit the line:

will get this error:

I tried to add indexing from the UI of google cloud page - add index to name property.
You'll want to check the mode of your database (https://cloud.google.com/sdk/gcloud/reference/alpha/firestore/databases/describe). It's likely your database is in Firestore native mode instead of Firestore in Datastore mode. If so, you'll want to use the Firestore client libraries instead of the Datastore client libraries, or switch your database type to Datastore mode.

IntegrityError: FOREIGN KEY constraint failed in django

I have a django view that causes FOREIGN KEY constraint failed. This is coming from a related question

django.db.utils.IntegrityError: FOREIGN KEY constraint failed
class Issue(models.Model):
borrower_id = models.ForeignKey(Student,on_delete=models.CASCADE)
book_id = models.ForeignKey(Books,on_delete=models.CASCADE)
issue_date = models.DateField(default=datetime.date.today)
issuer = models.ForeignKey(CustomUser,on_delete=models.CASCADE)
class Return(models.Model):
return_date = models.DateField(default=datetime.date.today)
borrowed_item = models.ForeignKey(Issue,on_delete=models.DO_NOTHING)
returner = models.ForeignKey(CustomUser,on_delete=models.DO_NOTHING)
Do DO_NOTHING is typically not a good option since (most) databases will check referential integrity. This means that they guarantee that if a ForeignKey refers (in this case to an Issue), then that means that the table that stores the issues should have a record with the primary key the Return item refers to.
Often DO_NOTHING is used in combination with a certain trigger in the database system (that Django is not aware of).
Typically the most popular choices foron_delete are:
models.CASCADE: in that case it will remove all Returns related to the removed item;
models.PROTECT: in that case it will raise an error to prevent removing the Issue; and
models.SET_NULL: this is done on a NULLable field (so with null=Ture), in which case the impacted Return(s) will set the field to NULL/None.
Another option might be to "soft delete" records, for example with the django-soft-delete package [pypi]. In that case a boolean is added to the Issue that specifies if the item is removed. The package will also transparently filter the objects, such that you only retrieve records that are "alive".
This edge case is not directly relevant for the OP, but may help others that wind up here based on the title:
An IntegrityError: FOREIGN KEY constraint failed will also be raised when trying to delete some object x, if there is a table in your database that Django is unaware of, and this table has a reference to object x.
This can happen, for example, if you remove a model from your code without properly migrating the changes.
As a result, the table remains in the database, but Django does not know anything about it, so, when object x is deleted, Django does not know it should also delete the corresponding row from this "orphaned" table.

wtf-forms populate.object AttributeError: 'Heatingcircuit' object has no attribute 'translate' when editing db entry

First of all I know what the problem is, But I dont know why or how to fix it, I know that the function needs to pass a string to the database, I have a view function for create and edit, in the create part I have added "str" to the function to over come the problem but I dont know how to do this for the edit part. The form has a querySelectField which is correctly populated for the create part, and when I submit the "str" transforms the query result correctly.
So to over come the problem I have added "str" to the create part of the function, but I cannot see how to add this to the edit part with the 'populate.obj', also I expect the field to be populated with the data stored in the db when I created the form, but it is not. It is only this QuerySelectfield which is causing the problems. Here is some of my code.
#bp.route('/control/addheatingcircuit', methods=['GET', 'POST'])
#bp.route('/control/addheatingcircuit/<int:id>', methods=('GET',
'POST'))
#login_required
def addheatingcircuit(id=None):
if id is not None:
obj = Heatingcircuit.query.get(id) or Heatingcircuit()
form = AddHeatingcircuitForm(request.form, obj=obj)

form.populate_obj(obj)
db.session.add(obj)
db.session.commit()
return redirect(url_for('index.index'))
else:
form = AddHeatingcircuitForm()
if form.validate_on_submit():
heatingcircuit = Heatingcircuit(name=form.name.data,
sensor_ID1=str(form.sensor_ID1.data),\ #here i have added 'str'
pin_ID1=str(form.pin_ID1.data))
db.session.add(heatingcircuit)
db.session.commit()

allow_blank=True, get_label='sensorID')
sensor_ID2 = QuerySelectField('sensor_ID2',

timer = db.relationship('Timers', backref='time')
def __repr__(self):
return '{}'.format(self.id)
I have looked at many questions on the forums but this is the closest match Flask WTF 'StringField' object has no attribute 'translate'
So as explained I expect the function on the edit an existing entry part to populate the form with the information already enregistered, and that when I change this and submit the populated form is excepted, instead I get this error message;
AttributeError: 'Heatingcircuit' object has no attribute 'translate'
(full error log possible if needed)
many thanks Paul
EDIT, I am looking at theis tutorial https://www.rithmschool.com/courses/flask-fundamentals/forms-with-wtforms
Here it talks about CSRF and a how to disable tokens for iterating over the form, Could my problem be this.
This problem affects SelectField as well.
Edit2
I tried the idea mentioned in the link http://wtforms.simplecodes.com/docs/0.6.1/ext.html#module-wtforms.ext.sqlalchemy.fields this code through an error "sqlalchemy.exc.InvalidRequestError: Entity '' has no property 'enabled'"
This is my code

AttributeError: 'Sensors' object has no attribute 'translate'
I had this same error message for the second half of the "def addpin():" function, I resaerched and found that I needed to return a string so I added str(form.sensor_ID1.data) "str" and this solved the problem there But the first half of the function is the edit part and and I now have the problem there but dont know how to solve it.
the error is here I believe;
if id is not None:
obj = Heatingcircuit.query.get(id) or Heatingcircuit()
form = AddHeatingcircuitForm(request.form, obj=obj)
if form.validate_on_submit():
form.populate_obj(obj)
db.session.add(obj)
db.session.commit()
Thanks for the help
Warm regards

Two problems. First, QuerySelectField's query_factory argument takes a query, not a list of results. So take off the .all():
sensor_ID1 = QuerySelectField('sensor_ID1',
query_factory=lambda: Sensors.query,
allow_blank=True, get_label='sensorID')
Secondly, the data for the given form field is going to give you a Sensors object. So you can't just cast it, you need to ask it for its id. The same goes for the pin_ID1 field. How you do this will depend on how the Sensors class is declared:
heatingcircuit = Heatingcircuit(
name=form.name.data,
sensor_ID1=form.sensor_ID1.data.sensorID,
pin_ID1=form.pin_ID1.data.pinID
)
