Write a tumblelog application with flask and mongoengine django

Edit on GitHub 1. A tumblelog is a blog that supports mixed media content, including text, images, links, video, audio, etc. For this we use the connect function. If running locally, the only argument we need to provide is the name of the MongoDB database to use:

You can, of course, update a record by using the update method. You can update the entire record, as shown in Listing 7. Of course you can continue to explore on the official website, which has a neat web-based interactive mongodb command prompt complete with tutorial as well as the official documents.

The first is using the Python module, PyMongo. To define a connection, simply pass in a database name to a connection instance. Python dictionaries, in this case, substitute the JavaScript object literals for creating new document definitions, and Python lists substitute JavaScript arrays.

The find method returns a database cursor object that you can iterate over. The similarity in syntax makes it easy to switch between the MongoDB command line and running commands with PyMongo.

For example, Listing 11 shows how to run a query with PyMongo. Run a query with PyMongo for e in employees. MongoEngine is a document-to-object mapper, which is similar in concept to an ORM. Listing 12 shows an example session with MongoEngine.

In this example, you use two field types: Blongo displays any blog entries entered upon page load and allows updating and deleting of any entries — in other words, all the standard CRUD operations.

The Django views have three methods: The cascading style sheets CSS definitions go in a separate static file. Assuming everything is installed and running well, create a new Django project and the necessary components as shown in Listing By adding a static directory to any application directory such as blogapp in this case and making sure that django.

Listing 14 shows the lines of the settings files that have been altered from the default settings. Lines of the settings files that have been altered from the default settings.

Listing 15 shows the code for all three template files. Code for the index. You want the sample blog to create new blog entries at the indexupdate existing blog posts, and delete them when desired. Each action is accomplished by posting to a specific URL.The MongoDB documentation project aims to provide a complete manual for the MongoDB database server describing its use, behavior, operation, and administration.

These docs will eventually replace MongoDB’soriginal documenta-. Oct 02,  · Using MongoDB with Python This part of the Bookshelf tutorial shows how the sample app stores its persistent data in a MongoDB database.

This page is part of a multi-page tutorial. From the tutorial (bold added for emphasis): First, create a simple “bare bones” application. Make a directory named tumblelog for the project and then, add the following content into a file named urbanagricultureinitiative.com tumblelog isn't something you install.

It's something you make. Flask and MongoEngine help makes development work easier. One common task in the development of backend applications is the pagination of database records.

Without pagination, the application server can run out of memory while generating a response from the database records. This post discusses a way to paginate MongoEngine records in your Python 3 Flask application . Join Stack Overflow to learn, share knowledge, and build your career.

Flask-Script for an easy-to-use development server Install with the following commands: pip install flask pip install flask-script pip install WTForms pip install mongoengine pip install flask_mongoengine Continue with the tutorial to begin building the \"tumblelog\" application.
