how to integrate recommender system(python file) to the django project.

问题

This is the python script made by my friend .How to integrate this file in my django project which contains all list of movies taken from the movierulz data set.Where should I integrate this code.

import numpy as np
import pandas as pd

# set some print options
np.set_printoptions(precision=4)
np.set_printoptions(threshold=5)
np.set_printoptions(suppress=True)
pd.set_option('precision', 3, 'notebook_repr_html', True, )
# init random gen
np.random.seed(2)



#users_file = "/media/sourabhkondapaka/Sourabh's/main_project/sandbox/ml-latest-small/ratings.csv"
#movies_file = "/media/sourabhkondapaka/Sourabh's/main_project/sandbox/ml-latest-small/movies.csv"
#users = pd.read_table(users_file,sep=',', header=None,names = ['user_id','movie_id','rating','timestamp'])
#movies = pd.read_table(movies_file, sep=',')



class popularity_based():
    def __init__(self,users,movies):
        self.users = users
        self.movies = movies
        self.user_id = None
        self.mean_ratings = None
        self.movielens= None
        self.c  = 0

    def create(self):
        self.movielens = pd.merge(users,movies)
        self.movie_ratings = self.movielens.ix[:,1:3]
        self.mean_ratings = self.movie_ratings.groupby('movie_id',as_index = True)['rating'].mean().sort_values(ascending = False)
        self.mean_ratings = pd.DataFrame(self.mean_ratings).reset_index()
        self.mean_ratings['title'] = self.mean_ratings['movie_id'].map(self.movies.set_index('movie_id')['title'])

    def recommend(self, user_id,topu): #no arguement required here, just for the sake of uniformness across other recommender implementations
        self.user_id = user_id
        #From = self.c
        #self.c += topu
        #To = self.c
        print(type(self.mean_ratings.as_matrix(columns=None)))
        return self.mean_ratings.ix[:topu,'title'].as_matrix(columns = None)

You have to ask yourself, what does this file do? If it functions as a utility that helps you get movie recommendations for a user, then it should be included in your utils.py under the main project. You can then use appropriate relative import and serve the content in the right view.
