How to add data in right collection in pymongo? - mongodb

Question

I want to add data in right collection considering by name. The code below is defining well. collection(db,name) returns the name of collection. But when I want to save the collection name via rightCollection = collections(db, name) and inserting it as db.rightCollection.insert({"1" : "Righ collection"}). Pymongo is creating the collection under name rightCollection not Peter. I want to insert data in Peter. Why is it so? Can I resolve it?
from pymongo import MongoClient
def collections(db,name):
if(name is 'Peter'):
return db.Peter
client = MongoClient()
db = client.myDB
name="Peter"
rightCollection = collections(db, name)
db.rightCollection.insert({"1" : "Righ collection"})

Answer 1

Using pymongo 3.2.2, you don't need the collections function, you can just use the collection name directly:
from pymongo import MongoClient
client = MongoClient()
db = client.myDB
db.Peter.insert_one({'1': 'Right collection'})
That should insert the document {'1': 'Right collection} into collection Peter under database myDB. To verify that the data is inserted correctly, you can use the mongo shell:
> use myDB
> db.Peter.find()
{ "_id": ObjectId("57df7a4f98e914c98d540992"), "1": "Right collection" }
Or, if you need the name Peter to be defined in a variable, you can do:
from pymongo import MongoClient
client = MongoClient()
db = client.myDB
coll_name = 'Peter'
db[coll_name].insert_one({'1': 'Right collection'})
