# Flask-Restless #

## Introduction ##

This is Flask-Restless, a [Flask][1] extension which facilitates the creation
of ReSTful JSON APIs. It is compatible with models which have been defined
using either [SQLAlchemy][sa] or [Flask-SQLAlchemy][fsa].

This document contains some brief instructions concerning installation of
requirements, installation of this extension, configuration and usage of this
extension, and building of documentation.

two copyright licenses:

## Contents ##

This is a partial listing of the contents of this package.

* `COPYING` - the copyright license under which this program is distributed to
  you (the GNU Affero General Public License version 3)
* `docs/` - the Sphinx documentation for Flask-Restless
* `examples/` - example applications of Flask-Restless
* `flask_restless/` - the Python package containing the extension
* `README.md` - this file
* `setup.py` - Python setuptools configuration file for packaging this
* `tests/` - unit tests for Flask-Restless

The `flask_restless` directory is a Python package containing the following

* `views.py` - the view class which implements the ReSTful API
* `manager.py` - the main class which end users will utilize to create ReSTful
  APIs for their database models
* `search.py` - functions and classes which facilitate searching the database
  on requests which require a search

## Installing ##

This application requires [Python][4] version 2.5, 2.6, or 2.7.

This application requires the following libraries to be installed:

* [Flask][1] version 0.7 or greater
* [SQLAlchemy][sa]
* [python-dateutil][5] version less than 2.0
* [simplejson][sj] only in Python 2.5
* [Flask-SQLAlchemy][fsa] only if your models are defined using Flask-SQLAlchemy

These requirements are also listed in the `requirements.txt` file. Using `pip`
is probably the easiest way to install these:

    pip install -r requirements.txt


    pip install Flask Flask-SQLAlchemy python-dateutil simplejson sqlalchemy

Technical note: simplejson is only required if you are using Python 2.5. The
built-in json module will suffice in later Python versions.

## Building as a Python egg ##

This package can be built, installed, etc. as a Python egg using the provided
`setup.py` script. For more information, run

    python setup.py --help

## How to use ##

For information on how to use this extension, build the documentation here or
[view it on the Web](http://readthedocs.org/docs/flask-restless).

## Testing ##

Running the unit tests requires the [unittest2][ut2] package, which backports
the functionality of the built-in `unittest` package from Python version 2.7 to
earlier versions. This requirement is also listed in the
`requirements-test.txt` file.

Using `pip` is probably the easiest way to install this:

    pip install -r requirements-test.txt


    pip install unittest2

The Python unit tests are contained in the `tests/` directory (which is a
Python package). To run the test suite, run the command

    python setup.py test

You can also run the unit tests in a less verbose way by doing


This is a Python module which, when executed, simply runs all unit tests.

[ut2]: http://pypi.python.org/pypi/unittest2

### Test coverage ###

You can measure the test coverage by running

    python setup.py coverage

Measuring test coverage requires the [coverage.py][cov] package, which can be
installed like this:

    pip install coverage

[cov]: http://nedbatchelder.com/code/coverage

### Testing validation ###

Validation is not provided directly by Flask-Restless, but it does provide a
way for users to indicate exceptions to catch. If you wish to test validation
of SQLAlchemy models with a real external SQLAlchemy validation library,
install the development version of [SAValidation][sav]:

    pip install -e "hg+http://bitbucket.org/rsyring/sqlalchemy-validation#egg=savlidation-dev"

The test suite will automatically skip these tests if it is not installed.

[sav]: http://pypi.python.org/pypi/SAValidation

## Building documentation ##

Flask-Restless requires the following program and supporting library to build
the documentation:

* [Sphinx][6]
* [sphinxcontrib-httpdomain][7], version 1.1.7 or greater

These requirements are also listed in the `requirements-doc.txt` file. Using
`pip` is probably the easiest way to install these:

    pip install -r requirements-doc.txt


    pip install sphinx "sphinxcontrib-httpdomain>=1.1.7"

The documentation is written for Sphinx in [reStructuredText][8] files in the
`docs/` directory. Documentation for each class and function is provided in the
docstring in the code.

The documentation uses the Flask Sphinx theme. It is included as a git
submodule of this project, rooted at `docs/_themes`. To get the themes, do

    git submodule update --init

Now to build the documentation, run the command

    python setup.py build_sphinx

in the top-level directory. The output can be viewed in a web browser by
opening `docs/_build/html/index.html`.
