Questions tagged [flask-admin]

Flask-Admin is an extension for the Flask framework. It can be used for building admin interfaces easily, with model scaffolding support for many existing python ORMs. Use this tag for questions related to this extension only, and not for general 'admin' functionalities in Flask.

Flask-Admin is an advanced, extensible and simple to use 'administrative interface building' extension for the Flask framework.

It comes with batteries included: model scaffolding for SQLAlchemy, MongoEngine, pymongo and Peewee ORMs, a simple file management interface and a lot of usage examples.

You are not limited by the default functionality - instead of providing simple scaffolding for the ORM models, Flask-Admin provides tools that can be used to construct administrative interfaces of any complexity, using a consistent look and feel.
