Requirements

Python

Version

This project is using Python3. Se be sure that it's available on your system.

Pip

Pip is a python dependency manager. Be sure to install it first.

Virtualenv

Once you've installed pip, you will need to work inside a virtualenv. A virtualenv is a convenient way to isolate your python packages. If you don't use a virtualenv, all the python libraries required will be installed system wide.

Install virtualenv:

pip install --user virtualenv

In the project directory create the virtualenv (here we will name it env):

virtualenv env

If python 3 is not the default python version on your system, you may have to specify you python 3 binary to virtualenv:

virtualenv --python=/usr/bin/python3 env

Then activate the environment before launching any python command. You will need to do that each time you want to work on the project:

. ./env/bin/activate

Your prompt should be modified and should contain something like (env).

Dependencies

All the project dependencies are managed using pip. Once you've activated your virtualenv, type:

pip install -r requirements.txt

Note: If you are using Debian/Ubuntu, be sure to have the python3-dev package installed or the installation will fail with errors like: fatal error: Python.h: No such file or directory.

You're ready to go!

Running the webapp

First be sure to activate your virtalenv using:

. ./env/bin/activate

The first time (and only the first time), you will need to first bootstrap your database:

./manage.py initdb

Then you just have to launch the following command and your server should be running on http://127.0.0.1:5000/:

./manage.py runserver

If you want to use a real webserver like gunicorn, just use the wsgy_dev.py file provided:

gunicorn webapp.wsgi_dev:application

Activate virtualenv and then

./manage.py runserver

Run tests

If you want to launch the test suite only once, run:

py.test tests

If you want to launch only one test file, use the command below:

py.test tests/test_mediafileapi.py

If you want to launch only one test in a test file:

py.test -s tests/test_mediafileapi.py::MediaFileApiTestCase::test_file_upload_multi_part_fail

Generate documentation

You will need ApiDocJs to generate the documentation. From the project root type:

apidoc -i api -o docs

To deploy it for example you can do:

rsync -avz docs/ [email protected]:/home/voxolab/www/docs/

Miscellanous

curl upload

curl -i -F file=@lcp_q_gov.wav http://localhost:5000/api/v1.0/files
