It will specify a file in which the data is going to store. For JSON format use json and for CSV format use csv. If you are specifying multiple fields the use comma in between them. It will specify the fields that will include in the export.

It will specify the collection to export. It will specify the name of the database in which mongoexport will run. It will return the version of mongoexport It will return the information about option and the use of mongoexport

The mongoexport tool also provides options.

If the mongoexport tool is not present in your system then you can install it from here.

If the specified file is not created then mongoexport tool will automatically create a file and store data in it.

In case we don’t use –out the file gets created at path where we are at the time of running cmd.

Here, the out command specifies the directory and the file in which the exported data is to be stored.

Mongoexport –db database_name –collection collection_name –type=csv –fields fields_names –out path_or_name_of_the_file Mongoexport –db database_name –collection collection_name –out path_or_name_of_the_file

You don't even have to have the field types be uniform between multiple documents. You can put in any number of fields here, of any type. This will return the newly added document with the embedded document:Īs no fields were defined in the model, we will need to provide any arbitrary set of fields to our dynamic document object. This reference is a key in app.config whose value is a dict containing the connection parameters: app.config = '\ But before the initialization is done, we'll need a reference to our MongoDB instance. Which we'll use to initialize a MongoEngine object.

Then, we can create the Flask app object: app = Flask(_name_) We will start by importing Flask and Flask-MongoEngine into our app:įrom flask_mongoengine import MongoEngine Now that we have installed Flask and Flask-MongoEngine, we need to connect our Flask app with a MongoDB instance.

Instructions to get and install MongoDB can be found in the official documentation.Īnd with that done, we'll also want to install the Flask-MongoEngine library: $ pip install flask-mongoengine Connecting to a MongoDB Database Instance Next, we'll need access to a MongoDB instance, MongoDB provides a cloud instance - the MongoDB Atlas - that we can use for free, however, we will be using a locally installed instance. To get started, let's install Flask if you don't have it already: $ pip install flask

To explore some of the features of MongoEngine, we'll be creating a simple movie API that allows us to perform CRUD operations on Movie instances. MongoEngine is an ODM (Object Document Mapper) that maps Python classes (models) to MongoDB documents, making it easy to create and manipulate documents programatically straight from our code. In this guide, we'll be exploring how to integrate MongoDB with Flask using a popular library - MongoEngine, and more specifically, its wrapper - Flask-MongoEngine.Īlternatively, you can integrate MongoDB with Flask-PyMongo. In this guide, we shall be taking a look at how to integrate one of the most popular NoSQL databases - MongoDB - with the Flask micro-framework. There are various databases to choose from, depending on your preference. Building a web app almost always means dealing with data from a database.
