Flask application generator for boosting your development.

Features

  • Well Defined Project Structure

    • Use factory pattern to generate Flask app.
    • Use Blueprints to organize controllers.
    • Split controllers, models, forms, utilities, assets, Jinja2 pages, Jinja2 macros into different directories.
    • Organize Jinja2 page assets (HTML, JavaScript, CSS) to the same directory.
    • Organize Jinja2 macro assets (HTML, JavaScript, CSS) to the same directory.
  • Batteries Included

    • Use Flask-SQLAlchemy and Flask-Migrate as database tools.
    • Use Flask-WTF to validate forms.
    • Use Flask-Script to help writing scripts.
    • Use permission_ to define permissions.
    • Use Bootstrap as frontend framework.
    • Use Bower to manage frontend packages.
    • Use Gulp and FIS_ to compile static assets.
    • Use Gunicorn to run Flask app and Supervisor to manage Gunicorn processes.
    • Use Fabric as deployment tool.
    • Use Sentry to log exceptions.
    • Use Nginx to serve static files.
  • Scaffold Commands

    • Generate project files: boost new <project>
    • Generate controller files: boost new controller <controller>
    • Generate action files: boost new action <controller> <action> [-t]
    • Generate form files: boost new form <form>
    • Generate model files: boost new model <model>

Development Guide

Init project

    boost new <your_project_name>

Setup backend requirements

::

cd <your_project_dir>
virtualenv venv
. venv/bin/activate (venv\Scripts\activate in Windows)
pip install -r requirements.txt

Note: if you failed in pip install -r requirements.txt in Windows, try to install package binaries directly:

  • pycrpyto: try to follow this article compiling-pycrypto-on-win7-64, or get the complied pycrypyto library directly: archive_pycrpyto_library.

.. _compiling-pycrypto-on-win7-64: https://yorickdowne.wordpress.com/2010/12/22/compiling-pycrypto-on-win7-64/ .. _archive_pycrpyto_library: http://archive.warshaft.com/pycrypto-2.3.1.win7x64-py2.7x64.7z

Init database


Create database with name ``your_project_name`` and encoding ``utf8``.

Update ``SQLALCHEMY_DATABASE_URI`` in ``config/development.py`` as needed.

Then init tables::

    python manage.py db upgrade

Run app
~~~~~~~

Run local server::

    python manage.py run

Setup frontend requirements

Install Node.js first and then install Bower, FIS and Gulp_ globally::

npm install -g bower
npm install -g fis
npm install -g fis-postpackager-simple
npm install -g gulp

Install local packages::

npm install
bower install

Run Gulp watch task


::

    gulp watch

LiveReload support

Install LiveReload browser extension from here_.

And use ``python manage.py live`` instead of ``python manage.py run`` to start app.

.. _here: http://livereload.com/extensions/

Scaffold commands
~~~~~~~~~~~~~~~~~

::

    boost new <project>
    boost new controller <controller>
    boost new action <controller> <action> [-t]
    boost new form <form>
    boost new model <model>
    boost new macro <category> <macro>
    boost new macro <macro>
    boost -v
    boost -h

Config app


Save ``config/production_sample.py`` as ``config/production.py``, update configs in ``config/production.py`` as needed and transfer it to server.

**Note**: remember to update ``SECRET_KEY`` in ``config/production.py``! You can generate random secret key as follows::

>>> import os
>>> os.urandom(24)

Init database

Create database with name your_project_name and encoding utf8.

And run::

export MODE=PRODUCTION
python manage.py db upgrade

Copy config files


Update project root path as needed in ``deploy/nginx.conf`` and ``deploy/supervisor.conf``.

::

    cp deploy/flask_env.sh /etc/profile.d/
    cp deploy/nginx.conf /etc/nginx/conf.d/<your_project_name>.conf
    cp deploy/supervisor.conf /etc/supervisor/conf.d/<your_project_name>.conf

Build assets
~~~~~~~~~~~~

Install Node.js first and then install Bower_, FIS_ and Gulp_ globally::

    npm install -g bower
