As the PyMongo doc described, InsertManyResult doesn't has the inserted_count attrbute. You can use len(result.inserted_ids) instead.

How to get the value of array in postman using parser = reqparse.RequestParser() in flask api?
Im getting an error says: NoneType' object is not subscriptable
And here is my code:
class CreateUser(Resource):
def post(self):
try:
conn = None
parser = reqparse.RequestParser()
parser.add_argument('username', type = str)
args = parser.parse_args()
name = args['username'][0]
return name
except Exception as e:
x = str(e)
x.replace('\n', '')
return {'status' : 'failed', 'message' : str(x)}
finally:
if conn is not None:
conn.close()
im getting error with this name = args['username'][0] and i also try to make this too name = args[0]['username'] and still error appears and when i just make this like name = args['username'] the postman replies null. please help me.
Use this
def post(self):
try:
conn = None
parser = reqparse.RequestParser()
parser.add_argument('username[0]', type = str)
parser.add_argument('username[1]', type = str)
args = parser.parse_args()
name = args['username[0]']
return name
except Exception as e:
x = str(e)
x.replace('\n', '')
return {'status' : 'failed', 'message' : str(x)}
finally:
if conn is not None:
conn.close()
Editing for multiple params
form data should be like this
username: "user1"
username: "user2"
username: "user3"
Yes you can pass multiple values with same key
def post(self):
try:
conn = None
parser = reqparse.RequestParser()
parser.add_argument('username', type = str, action='append')
args = parser.parse_args()
name = args['username']
print(name) # ['user1', 'user2','user3'] you can traverse over this list
Here is the complete code where i am trying to use ForexConnect().get_history(.... instead of fx.get_history( and i do not want this line of code "with ForexConnect() as fx:" how to achieve this ,the last section of code given produces excpetion issues .
Why i do not want to use "with ForexConnect() as fx:" The reason is once the session "with ForexConnect() as fx:" the function is logged out .My idea is to be in the session after once logged in .So i do not want to try this with "with ForexConnect() as fx:"

Here i want to login once and be in the logged in session forever.
With the below function this is working fine .But here the problem is once the With section is over the session is disconnected.
with ForexConnect() as fx:
try:
fx.login(str_user_id, str_password, str_url,
str_connection, str_session_id, str_pin,
common_samples.session_status_changed)
history = fx.get_history(str_instrument, str_timeframe, date_from, date_to, quotes_count)
current_unit, _ = ForexConnect.parse_timeframe(str_timeframe)
To stay in the session tried the below code without using the "With" and as :
Here the login is successful but could not get the data in history = ForexConnect().get_history
Error Code :
ForexConnect().login(str_user_id, str_password, str_url,
str_connection, str_session_id, str_pin,
common_samples.session_status_changed)
**history = ForexConnect().get_history(str_instrument, str_timeframe, date_from, date_to, quotes_count)**
How to make it the ** ** code work without any exception error without using With --- as : keyworkds.
what is the alternative for this with and as : why when i try to access as history = ForexConnect().get_history ( ... it is giving error how to overcome this issue.
I am giving a wrong input and I want an exception to be raised. Somehow this is not happening. This is my unit test code:
def test_invalid_bag_json_conversion_1(self):
file_name = "../test/test_files/wrong_bag.bag"
ru = RosbagUploader(file_name, self.json_output, "", "", "", "")
status = ru.start()
self.assertRaises(Exception, RosbagUploader, file_name, self.json_output, "", "", "", "")
self.assertEquals(ReturnCodes.FAIL, status)
and my code that I am testing:
class RosbagUploader(object):
"""
#brief Uploads deserialized input Rosbag file to ElasticSearch or
stores it locally
"""
def __init__(self, _rosbag_filepath, _json_filename, _es_addr, _es_index,
_es_type, _buffer_size):
self.overall_status = ReturnCodes.SUCCESS
self._rosbag_filepath = _rosbag_filepath
self._json_filename = _json_filename
self._buffer_size = _buffer_size if _buffer_size > 0 else 5000
self._es_type = _es_type
self._es_addr = _es_addr
self._es_index = _es_index
self._es_buff = []
try:
self._rosbag = rosbag.Bag(_rosbag_filepath, "r")
if self._es_addr:
self._es = Elasticsearch() if _es_addr == "" else \
Elasticsearch([_es_addr])
self._total_num_record = self._rosbag.get_message_count()
except:
print("[ERROR] {}".format(sys.exc_info()))
self.overall_status = ReturnCodes.FAIL
It shows the output that the exception is raised as below:
[ERROR] (<class 'rosbag.bag.ROSBagException'>, ROSBagException(), <traceback object at 0x7fdcb463e8c0>)
EException AttributeError: "'RosbagUploader' object has no attribute '_rosbag'" in <bound method RosbagUploader.__del__ of <rosbag_deserializer_core.RosbagUploader object at 0x7fdcb4899ad0>> ignored
Which is what it should do. But why doesnt it raise the exception?
You are essentially ignoring the exception since you are not re-raising after the print statement:
try:
[...]
except:
print("[ERROR] {}".format(sys.exc_info()))
self.overall_status = ReturnCodes.FAIL
You need to re-raise for callers to receive the exception:
try:
[...]
except:
print("[ERROR] {}".format(sys.exc_info()))
self.overall_status = ReturnCodes.FAIL
raise
Do you have a __del__ destruction method? Seems to be failing there.
I want to request some parameters from a external web app. I create an API with flask and query data from MySQL. I able to query the data if I gave a fix input but not when using request.args. I try both request.args['name'] and request.args.get('name') but return the output of Exception path.
Below is my current code. I comment out the fix input I used.
from flask import Flask,jsonify,abort,make_response,request,render_template
import MySQLdb
import MySQLdb.cursors
#app.route('/KLSE/search', methods=['GET'])
def KLSEsearch():
db = MySQLdb.connect(host='vinus.mysql.pythonanywhere-services.com',user='vinus',passwd='Vindex2016',db='vinus$default',cursorclass=MySQLdb.cursors.DictCursor)
curs = db.cursor()
#name ='P'
#macd = 'H'
#volumeMin = '_'
#volumeMax = '_'
#stoch ='H1'
#bollinger ='H'
#rsi ='H1'
#atr ='LV'
#trade = 'HOLD'
#limit = 3
#offSet = 1
name = request.args.get('name')
volumeMin = request.args['volumeMin']
volumeMax = request.args['volumeMax']
macd = request.args['macd']
stoch = request.args['stoch']
bollinger = request.args['bollinger']
rsi = request.args['rsi']
atr = request.args['atr']
trade = request.args['trade']
limit = request.args['limit']
offSet = request.args['offSet']
query0 = "SELECT * FROM KLSE WHERE Stock LIKE '%s' AND"
#query1 = "(Vindex BETWEEN (IF(%s='_',-5000,%s)) AND (IF(%s='_',5000,%s))) AND "
query2 = "(Volume_changes_pc BETWEEN (IF (%s='_',-5000,%s)) AND (IF(%s='_',5000,%s))) AND "
query3 = "MACD LIKE %s AND "
query4 = "STOCH LIKE %s AND "
query5 = "BOLLINGER LIKE %s AND "
query6 = "RSI LIKE %s AND "
query7 = "ATR LIKE %s AND "
query8 = "TRADE LIKE %s LIMIT %s OFFSET %s"
query = query0+query2+query3+query4+query5+query6+query7+query8
input = name+"%",volumeMin,volumeMin,volumeMax,volumeMax,macd,stoch,bollinger,rsi,atr,trade,limit,offSet
try:
curs.execute(query,(input))
g = curs.fetchall()
except Exception:
return 'Error: unable to fetch items'
#return "hihi"
return jsonify({'Stock': g})
The output with fix value as below. I think it shows the query to MySQL is correct.
http://vinus.pythonanywhere.com/KLSE/search1
For the user input value, which use the args,
http://vinus.pythonanywhere.com/KLSE/search?atr=%&bollinger=%&macd=%&name=M&rsi=%&stoch=%&volumeMax=&volumeMin=&trade=HOLD&limit=5&offSet=1
What is the right way, get the parameters? volumeMin,volumeMax,limit and offSet are in float and integers.
You have to serialize your data first.
def serialize():
return {
"id" : g.id,
"volumeMin" : g.name,
"volumeMax" : g.address,
"macd" : g.city,
"stoch" : g.state,
"zipCode" : g.zipCode,
"bollinger" : g.bollinger,
}
#app.route("/KLSE/search/.json")
def stock_json():
query = your.db.query()
return jsonify(Stock=[i.serialize for i in query])
I get this error and I don't know what the problem is.

How can I fix this? I would appreciate any help.
Since xmldi['Storingen']['Ongepland'] has the value None
id = xmldi['Storingen']['Ongepland']['Storing']['id']
should be changed to:
id = xmldi['Storingen']['Gepland']['Storing']['id']
