mongodb - PyMongo not recognizing if the name of the collection is client -


i have cursor open on database , have collection name client in database. when i'm trying execute query like

def connect_to_primary(host, port):     """this function connect primary host in replicaset"""     connection = mongoclient(str(host), int(port))     admindb = connection.admin     pri_host_port_con = admindb.command("ismaster")     primary_con = pri_host_port_con['primary']     pri_host_port = primary_con.replace(':', ' ').split()     pri_host = pri_host_port[0]     pri_port = pri_host_port[1]     final_connection = mongoclient(str(pri_host), int(pri_port))     return final_connection  connect_to_primary(host,port)[db].client.find({}).distinct('clientid')

i getting following error:

file "/usr/lib64/python2.7/site-packages/pymongo/database.py", line 1116, in __call__     self.__name, self.__client.__class__.__name__)) typeerror: 'database' object not callable. if meant call 'find' method on 'mongoclient' object failing because no such method exists.

what's wrong here?

the reason getting because database instances have client attribute returns client instance of database shown in following interactive python session.

>>> import pymongo >>> connection = pymongo.mongoclient() >>> db = connection["test"] >>> db database(mongoclient(host=['localhost:27017'], document_class=dict, tz_aware=false, connect=true), 'test') >>> db.client mongoclient(host=['localhost:27017'], document_class=dict, tz_aware=false, connect=true)

the solution use the get_collection method or [] operator.

>>> db["client"] collection(database(mongoclient(host=['localhost:27017'], document_class=dict, tz_aware=false, connect=true), 'test'), 'client') >>> db.get_collection("client") collection(database(mongoclient(host=['localhost:27017'], document_class=dict, tz_aware=false, connect=true), 'test'), 'client')

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
