The Project Name is Art 12 Consultation Tool

Travis Docker

Prerequisites - System packages

These packages should be installed as superuser (root).

Debian based systems

Install these before setting up an environment:

apt-get install python-setuptools python-dev libmysqlclient-dev \
libldap2-dev libsasl2-dev python-virtualenv mysql-server git

RHEL based systems

Install Python2.7 with PUIAS: https://gist.github.com/nico4/9616638

Run these commands:

curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python2.7 -

pip2.7 install virtualenv

yum install mysql-server mysql git openldap-devel cyrus-sasl-devel \
mysql-devel

Install dependencies

We should use Virtualenv for isolated environments. The following commands will be run as an unprivileged user in the product directory:

1.Clone the repository:

git clone git@github.com:eea/art12-viewer.git -o origin art12
cd art12

2.1.Create & activate a virtual environment:

virtualenv --no-site-packages sandbox
echo '*' > sandbox/.gitignore
source sandbox/bin/activate

2.2.Make sure setuptools >= 0.8 is installed:

pip install -U setuptools

3.Install dependencies:

pip install -r requirements-dep.txt

4.Create a configuration file:

cd art12
mkdir -p instance
cp settings.py.example instance/settings.py

# Follow instructions in settings.py.example to adapt it to your needs.
# MAPS_PATH and MAPS_URI should be filled in according to your local deployment
# e.g: MAPS_PATH = '/Users/foo/art12/art12/static/maps/' MAPS_URI = '/static/maps/'

5.Set up the MySQL database:

# Replace [user] and [password] with your MySQL credentials and [db_name] with the name of the database:
mysql -u[user] -p[password] -e 'create database [db_name] CHARACTER SET utf8 COLLATE utf8_general_ci;'
./manage.py db upgrade

Tests

  1. Run the application by starting docker containers:

    docker-compose up -d
    
  2. Access the art12-mysql container:

    docker exec -it art12-mysql bash
    
  3. Create the test database and grant all the privileges to the test user:

    create database art12test character set utf8 collate utf8_general_ci;
    create user 'test'@'%' identified by 'test';
    grant all privileges on art12test.* to 'test'@'%';
    
  4. Make sure to complete the data for environment variables in docker/art12.env file:

    # test art12
    DB_NAME_TEST=art12_test
    DB_USER_TEST=test
    DB_PASSWORD_TEST=test
    DB_HOST_TEST=mysql
    
  5. Access the art12-app container:

    docker exec -it art12-app bash
    
  6. Install dependencies:

    pip install -r requirements-dev.txt
    
  7. Run tests:

    py.test testsuite
    

Build production

Setup the production environment like this (using an unprivileged user)::

# install dependencies, see above
cd /var/local/art12
source sandbox/bin/activate

At this stage, the application is up and running. You should also configure:

* firewall policy
* public webserver (see vhost.conf.example for an example)
* start supervisord with the system (see init-svisor.example as an example
  init script)

Build staging

To setup a staging environment, follow the same steps as above. Create and use a different database (for example art12staging).

Factsheet generator

Printouts work using wkhtmltopdf 0.12.2.1. Using an older version may cause problems in rendering pdfs.

If you don't have this version installed, add it to your virtualenv.

  1. Go to http://wkhtmltopdf.org/downloads.html and select the build corresponding with your system. Copy the direct link into your clipboard.

  2. Install it locally in your virtualenv

    • For RedHat-based systems in production:

        wget $PASTE_URL_COPIED_AT_STEP_1
        # $PACKAGE is the file downloaded with wget
        sudo rpm -i --prefix=/var/local/wkhtmltox-0.12.1 $PACKAGE.rpm
        # If the command fails because the file is already installed
        # copy `wkhtmltopdf` from the installation directory and skip
        # the next command
        cp /var/local/wkhtmltox-0.12.1/bin/wkhmtltopdf sandbox/bin/
      
    • For RedHat-based development systems:

        # If you don't work on projects that require other versions
        # Install this version globally
        wget $PASTE_URL_COPIED_AT_STEP_1
        sudo rpm -i $PACKAGE.rpm
      
    • For Debian based systems:

        wget $PASTE_URL_COPIED_AT_STEP_1
        dpkg-deb -x wkhtmltox-0.12.1_<your_distro>.deb sandbox
        cp sandbox/usr/local/bin/wkhtmltopdf sandbox/bin
