Flask-Generate

Flask-Generate is a Flask extension that allows you to create web applications faster by creating models, routes and forms from console. It also generates scaffolds with CRUD operations.

Usage

Installation

pip install Flask-Generate

Generate a new Flask app

With Flask-Generate you can start a new project that contains base code to start working with

flask-generate app <my-app-name>

The flask-generate app command comes with two optional flags.

• --type: Indicates the app structure
  • options: MVC and Blueprint
  • default: mvc
• --orm: The ORM option to generate models based on it
  • options: SQLAlchemy and Peewee
  • default: SQLAlchemy

Example:

flask-generate app <app-name> --type blueprint --orm sqlalchemy

Generators

Once you have the Flask-Generate extension installed, you have access to the generate commands group and start working with models, forms and blueprints.

Blueprint

Blueprint generation will depend on the chosen app structure, if the chosen structure it's MVC the new blueprint will be saved on the blueprints folder as a Python module, else, the blueprint will be a Python package, similar to a Django app.

Arguments:

• name: Generates a Python file or package with this param

Example:

flask generate blueprint posts

Dest for mvc-like apps: my-app/blueprints/posts.py Dest for blueprint-like apps: my-app/posts

Models

Flask-Generate takes the GENERATE_ORM constant from settings to create models depending on the chosen ORM

Arguments:

• name: The model name, must be in PascalCase
• fields: List of model fields, must be declared as follows; field_name:type
• -d | --dest: File or Blueprint name where the model will be saved.

Example:

flask generate model Post title:str body:text --dest posts

Generated models should be saved on models/posts.py for mvc-like apps and posts/models.py for blueprint-like apps

Forms

Same as model command it takes the same parameters, but generates a form using the WTForms library.

Arguments:

• name: The model name, must be in PascalCase
• fields: List of model fields, must be declared as follows; field_name:type
• -d | --dest: File or Blueprint name where the model will be saved

Example:

flask generate form Post title:str body:text --dest posts

Generated forms should be saved on forms/posts.py for mvc-like apps and posts/forms.py for blueprint-like apps.

scaffolds

Flask-Generate can create a fully functional scaffold with CRUD operations; the scaffold generates all the necessary code to start faster (model, forms, routes and templates)

Arguments:

• name: This will be used to generate the related scaffolding files or a full package
• model: Model name that generates a SQLAlchemy/Peewee class to work with
• fields: Model fields that also will be used to generate the form

Example:

flask generate scaffold posts Post title:str body:text
