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>
  • Generate macro files: boost new macro <category> <macro> or boost new macro <macro>

Installation

::

pip install flask-boost

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_pycrpytolibrary.

.. _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

Recommended IDE

PyCharm_ is the recommended IDE for Flask-Boost.

Recommended preferences:

* In ``Preferences -> Project -> Project Interpreter``, set ``venv`` as project interpreter.
* In ``Preferences -> Project -> Project Structure``, set ``application/pages`` and ``application/macros`` as template folders, set ``application`` and ``application/static/css`` as resource folders.
* In ``Language & Frameworks -> JavaScript -> Bower``, set ``bower.json`` as bower.json.

First Production Deploy
-----------------------

Config server

Install mysql-server, python-virtualenv, git, supervisor, nginx, g++, python-dev, libmysqlclient-dev, libxml2-dev, libxslt-dev on your server.

Install requirements

::

    git clone **.git
    cd <your_project_dir>
    virtualenv venv
    . venv/bin/activate
    pip install -r requirements.txt

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

Install local packages::

    npm install
    bower install

Then::

    gulp
    python manage.py build

.. _Bower: http://bower.io
.. _FIS: http://fex-team.github.io/fis-site/
.. _Gulp: http://gulpjs.com

Start app

::

service nginx restart
service supervisor restart

Daily Production Deploy

Update HOST_STRING in config with the format user@ip.

Commit your codes and run::

git push && fab deploy

P.S. If you wanna to deploy flask with Apache2, see this_ post.
