Python print function

There is some useful tricks in python (3.x) to print objects.

Alternatively , you can code 3.x print function calls in code to be run by 2.x, by enabling the function call variant with statement like the following coded at the top  of a script , or anyware in an interactive session:

from __future__ import print function

For example here is an exmaple to sepretare print object and to log data into file :

from __future__ import print_function

x = 'Beka'
y = 99
w = '[item]'

print(x,y,w,sep='...')
print(x,y,w,file=open('log3.txt','a')) ## log into file


mongoengine objects to json

If you want to make json data from mongoengine objects.

example is given from flask framework

@app.route('/json', methods=['GET', 'POST'])
def json_data():
    return Company.objects.all().to_json()


If you want to convert json data into mongodb object try this

c = Company.objects.from_json(company)

mongodb $in

We know that "IN" operator is very useful in SQL , It allows to specify various values in where clause.

SELECT Firstname,Lastname FROM Users WHERE City IN ('Tbilisi','London');


This is very simple and clear in SQL , this would return all first name and last name from Users Table where the City column is either Tbilisi or London.

But how to run similar query in Mongodb ?  I hope you have already touch mongo :)

First Let me introduce structure of the my test mongodb collection "Users".
You can download and import test data from here 

One document entry will look like this.

{
    "_id" : ObjectId("51f80e4ba44433577cb1bdbc"),
    "Firstname" : "Leqso",
    "Lastname" : "Zazikashvili",
    "City" : "Tbilisi",
    "Languages" : [
        "English",
        "Spanish",
        "German"
    ]
}




Now lets write query to fetch all entries from mongodb where the City is Tbilisi or London

db.users.find(
 { City: {$in:["Tbilisi","London"]} }

)

As we can see $in operator selects the entries where the field value equals any value in the specified array. We can also get this entries from subarray.This will fetch all entries where subarray of languages contains "Chinese" or "Spanish" 

db.users.find(
  { Languages: {$in:["Chinese","Spanish"]} }
)
