Create Mongo Database From JSON Files

Here is how to create Mongo Database from JSON files.
Create JSON files with data. Example, I have created a json file named players.json with following data:
{
"first_name": "Virat",
"last_name": "Kohli",
"type": "batsman",
"age": 28,
"team": "Delhi Daredevils"
}
{
"first_name": "Mahendra",
"last_name": "Dhoni",
"type": "all rounder",
"age": 38,
"team": "Big Bengaluru"
}
{
"first_name": "Rohit",
"last_name": "Sharma",
"type": "baller",
"age": 32,
"team": "Mohali Wale"
}
and created teams.json file with the following data:
{
"name": "Delhi Daredevils",
"city": "Delhi",
"won": 2
}
{
"name": "Big Bengaluru",
"city": "Bengaluru",
"won": 3
}
{
"name": "Mohali Wale",
"city": "Mohali",
"won": 0
}

Now, lets add this data to collections in a database of MongoDB.

For that open a new terminal/command prompt and run MongoDB by using the command:
mongod
In another terminal open the folder where both the json files are there and run the following commands:
mongoimport --db ipldb --collection players --file players.json
and
mongoimport --db ipldb --collection teams --file teams.json
This will create a database named ipldb abd add two collections to it namely players and teams with three records each as found in the json files.

Now to view the database collections and it's documents, run the following:

mongo ipldb

  • This will open the database named ipldb

db.players.find()




  • This will show all documents in players collection
db.teamss.find()




  • This will show all documents in teams collection

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Python - List - Append, Count, Extend, Index, Insert, Pop, Remove, Reverse, Sort

🐍 Advance List List is widely used and it's functionalities are heavily useful. Append Adds one element at the end of the list. Syntax list1.append(value) Input l1 = [1, 2, 3] l1.append(4) l1 Output [1, 2, 3, 4] append can be used to add any datatype in a list. It can even add list inside list. Caution: Append does not return anything. It just appends the list. Count .count(value) counts the number of occurrences of an element in the list. Syntax list1.count(value) Input l1 = [1, 2, 3, 4, 3] l1.count(3) Output 2 It returns 0 if the value is not found in the list. Extend .count(value) counts the number of occurrences of an element in the list. Syntax list1.extend(list) Input l1 = [1, 2, 3] l1.extend([4, 5]) Output [1, 2, 3, 4, 5] If we use append, entire list will be added to the first list like one element. Extend, i nstead of considering a list as one element, it joins the two lists one after other. Append works in the following way. Input l1 = [1, 2, 3] l1.append([4, 5]) Output...

269. Alien Dictionary

  Solution This article assumes you already have some confidence with  graph algorithms , such as  breadth-first search  and  depth-first searching . If you're familiar with those, but not with  topological sort  (the topic tag for this problem), don't panic, as you should still be able to make sense of it. It is one of the many more advanced algorithms that keen programmers tend to "invent" themselves before realizing it's already a widely known and used algorithm. There are a couple of approaches to topological sort;  Kahn's Algorithm  and DFS. A few things to keep in mind: The letters  within a word  don't tell us anything about the relative order. For example, the presence of the word  kitten  in the list does  not  tell us that the letter  k  is before the letter  i . The input can contain words followed by their prefix, for example,  abcd  and then  ab . These cases will never ...
