what am I missing here? pymongo

Question

from pymongo import MongoClient
from bson.objectid import ObjectId

class AnimalShelter(object):
    #CRUD operations for animals collection in MongoDB
    
    def __init__(self, username, password):
        #initializing Mongo Client
        self.client = MongoClient('mongodb://%s:%s@127.0.0.1:53310/AAC' % (username, password))
        self.database = self.client['AAC']
        
                                  
        # Method to implement the C in CRUD
    def create(self, data):
        if data is not None:
            if data:
                self.database.animals.insert_one(data)
                return True
        else:
            return False
            
            
    def read(self, search):
        if search is not None:
            if search:
                searchResult = self.database.animals.find(search)
                return searchResult
        else:
            exception = ("Nothing to see here folks.")
                return exception

This is my class that I created, I am trying to test the output.

from animal_shelter import AnimalShelter

#defining data

data = {"age_upon_outcome" : "3 years",
    "animal_id" : "A746874",
    "animal_type" : "Cat",
    "breed" : "Domestic Shorthair Mix",
    "color" : "Black/White",
    "date_of_birth" : "2014-04-10",
    "datetime" : "2017-04-11 09:00:00",
    "monthyear" : "2017-04-11T09:00:00",
    "name" : "",
    "outcome_subtype" : "SCRP",
    "outcome_type" : "Transfer",
    "sex_upon_outcome" : "Neutered Male",
    "location_lat" : 30.5066578739455,
    "location_long" : -97.3408780722188,
    "age_upon_outcome_in_weeks" : 156.767857142857}

#search criteria
search = {"animal_id":"A746874"}

#instantiating an object
assignment = AnimalShelter()

#calling the method
success = assignment.create(data)
print(success)

#call read method
results = assignment.read(search)
print(results)

I keep getting this error which I am having trouble understanding and correcting. I thought I was adding or importing the database when I initialized the mongo client. So how is it that my object doesn't have a database?

TypeError                                 Traceback (most recent call last)
 in 
     26 
     27 #calling the method
---> 28 success = assignment.create(data)
     29 print(success)
     30 

AttributeError: 'AnimalShelter' object has no attribute 'database'

I am unsure about how to actually correct this. Is there a connection that I am not making between my class that I am creating and the mongo database that I am wanting to use?
