Is there any way to group them in a more hierarchical manner, like how the templates go under the 'blueprint1/photos' sub-directory? Of course I can put all the photo views in their own module to keep them organized separately, but what if I want to change the parent 'blueprint1/photos' path to something else? I'm sure I can invent a function or decorator that groups related routes under the same root path, but then I still have to name all the functions with the photos_ prefix and reference them like url_for('blueprint1.photos_show') It seems like blueprints are the answer when a Flask app gets large and you need to group and compartmentalize similar parts together, but you cannot do the same thing when the blueprints themselves get large.įor reference, in Laravel you can group related "views" under a Controller class where the views are methods. The problem here is that all the views related to the photos section of blueprint1 are located at the "top level," right with maybe blueprints for videos or audio or whatever (named videos_index().). This Blueprint class within the flask. Return render_template('photos/show.html', methods=) A Blueprint in Flask is a 'mold' or template for creating parts of web applications. I can't think of a better way of doing it than: # app/blueprints/blueprint1/_init_.pyīlueprint1 = Blueprint('blueprint1', _name_, photos_index(): Here, we will use FlaskSQLAlchemy and SQLite DB. But what if I need to group routes and logic further under a blueprint?įor example, I have blueprint1 with url_prefix='/blueprint1' and maybe under that I want to have a collection of views revolving around a user sharing photos and other users commenting on them. We will create a simple Flask CRUD application that can Create / Retrieve / Update / Delete Employee Information. They both can have resources, such as static files, templates, and views that are associated with routes. in the templates folder for the blueprint, move templates Update any references. Each Flask Blueprint is an object that works very similarly to a Flask application. from flask import Blueprint, rendertemplate home Blueprint(home. I think this is pretty much exactly what blueprints are for. In this section, you’ll learn in detail how a Flask Blueprint is implemented and used. Adding nestable blueprints into Flask is not as trivial as automatically appending a prefix to routes. It is possible to register a blueprint on another blueprint. START: Part from the docs Nesting Blueprints. My app is divided into several mostly disparate parts that share things like users/sessions/security and base template and everything but mostly do not interact much, and should be routed under different paths like /part1/. Blueprints are a way to organize your code in Flask to keep independent sections of your app as separate as possible. Flask 2 was released with support for nested blueprints. I'm still new to Flask, so there may be an obvious way to accomplish this, but I haven't been able to figure it out so far from the documentation.
