This article will explain in detail how to use Blueprints to reconstruct the blog project in Flask. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

Today, after refactoring and configuring the Flask_Blog project using Blueprints, we will learn how to ReFactor our application usage blueprint. The blueprint allows us to split the application into more manageable parts. We also move the configuration to our own file and create a configuration class. Finally, we will transfer the creation of the application to our own functionality. This is called an application factory, and it allows us to easily create multiple instances of the application using different configurations. Let's get started: what is Flask Blueprints?

Official explanation: flask uses the concept of blueprints to make application components and support common patterns in applications or applications. Blueprints can greatly simplify the way large applications work and provide a core way for Flask extensions to register application operations. The Blueprint object works like a Flask application object, but it is not really an application. Instead, it is a blueprint for how to build or extend the application.

We can understand that a blueprint is a template for generating "parts" of a Web application. You can think of it as a mold:

Create new folders main, posts, users under Flask_Blog\ flaskblog, and create an empty file _ _ init__.py in each folder:

Create a new routes.py under Flask_Blog\ flaskblog\ mian:

Create a new forms.py under Flask_Blog\ flaskblog\ posts:

Create a new routes.py under Flask_Blog\ flaskblog\ posts:

Create a new forms.py under Flask_Blog\ flaskblog\ users:

Create a new utils.py under Flask_Blog\ flaskblog\ users:

Create a new routes.py under Flask_Blog\ flaskblog\ users:

Create a new config.py under Flask_Blog\ flaskblog\:

Modify Flask_Blog\ flaskblog\ _ _ init__.py:

Modify the run.py under Flask_Blog:

Modify Flask_Blog\ flaskblog\ models.py:

Modify the hyperlink containing url_for () in all pages under Flask_Blog\ flaskblog\ templates as a blueprint. Take layout.html as an example:

This is the end of the project on how to use Blueprints to reconstruct the blog in Flask. I hope the above content can be of some help and learn more knowledge. If you think the article is good, you can share it for more people to see.
