IMAMD

IMAMD (IMAM Dashboard) is a project developed for UNICEF and intended to leverage information technology, libre software ideals and the existing cellular network infrastructure to help in implementation and coordination of Integrated Management of Acute Malnutrition programmes on a local and national level.

Quick Installation for Developers

The following has been tested on Ubuntu Server 14.04 LTS (which is our target platform). Other versions of GNU/Linux or Mac OS X will require some minor adjustments. Please note, it is recommended to develop IMAMD using a dedicated virtual machine with our target operating system installed (even if you do use the same platform!).

1. First install all the needed dependencies:

   sudo apt-get install git postgresql-9.3 postgresql-9.3-postgis-2.1 python-virtualenv python-dev
   libpq-dev postgresql-server-dev-all
   

2. Then get the sources (you may want to use your username and password here):

   git clone https://github.com/system7-open-source/imamd.git imamd
   

3. Now create a python virtual environment:

   virtualenv --no-site-packages imamd-venv
   

4. Activate the virtual environment (has to be done every time you want to run the application):

   source imamd-venv/bin/activate
   

5. Enter the source code:

   cd imamd
   

6. Either install python requirements for a production environment:

   pip install -r requirements/production.txt
   

   or for development:

   pip install -r requirements/development.txt
   

7. Create an isolated node.js environment integrated with the newly initialised Python virtual environment:

   nodeenv -p  # This may take a while
   

8. Install bower in the newly created node.js environment:

   npm install -g bower
   

9. Create the database imam_test (ignore the errors) and enable Postgis (you may want to change password for the PostgreSQL user used by IMAMD and modify IMAMD configuration accordingly):

   sudo -u postgres psql -f make_imam_test.sql
   sudo -u postgres psql -d imam_test -f enable_postgis.sql
   

10. Enter the application:

    cd imam
    

11. Add structure to the database:

    ./manage-test.py migrate
    

12. [optional] Set DEBUG to True in imam/imam/devel_settings.py (e.g. to activate django-debug-toolbar)

13. [optional] Download and load your data into the database (this may take a while):

    git clone url-to-your-data-repository imamd-data
    ./manage-test.py loaddata imamd-data/your-data-file-name.json.gz
    

14. Install required bower packages:

    bower install
    

15. Prepare static resources (JS & CSS):

    ./manage-test.py collectstatic
    

16. Run the system:

    ./manage-test.py runserver
    

17. See it running in a web browser by entering the url:

    http://localhost:8000/
    

For further options see the documentation at http://djangoproject.com. Please note that whenever the command ./manage.py is mentioned in the django documention, you should use ./manage-test.py instead.

Operation

If the DJANGO_SETTINGS_MODULE environment variable is left undefined, the environment will default to imam.preset.url_settings which has a complex method of defining the database.

1. If no environment variables are defined, it will use the database hard-coded in preset/staging.py, with staging settings (DEBUG=True etc.)

2. If environment variable DATABASE_URL is defined, it is used to define the database connection. For example:

   postgis://imamd_db_user:12345678@localhost/imam_test?staging=true
   

   is the same as:

   DATABASES = {
   'default': {
       'ENGINE': 'django.contrib.gis.db.backends.postgis',
       'NAME': 'imam_dev',
       'USER': 'imamd_db_user',
       'PASSWORD': '12345678',
       'HOST': 'localhost',
       'OPTIONS': { } },}
   DATABASE_URL_QUERIES['staging'] = 'true'
   

3. If DATABASE_URL_QUERIES['staging'] == 'true', then 'preset/staging.py' will be imported, otherwise 'preset/production.py' will be imported.

Rebuilding Locations Data

The "Locations" data table is a complex MPTT tree structure, in which the internal indexes can become corrupted.

To refresh the indexing data in those tables, execute the following command:

./manage-test.py rebuild_locations_tree

Outgoing E-mail Configuration

This project sends e-mail using the django-mail-queue application.

see http://django-mail-queue.readthedocs.org/en/latest/usage.html or the sample in imam/core/tests/test_the_utils.py.

Select your SMTP mail transfer agent using the usual Django settings variables (see https://docs.djangoproject.com/en/dev/ref/settings/).

In a simple deployment, this may be best done in a preset, such as:

# this sample sends e-mail using a Google account

EMAIL_HOST = 'smtp.gmail.com'  #The host to use for sending email.

# Password to use for the SMTP server defined in EMAIL_HOST.
EMAIL_HOST_PASSWORD = os.environ.get("EMAIL_HOST_PASSWORD", "12345678")

EMAIL_HOST_USER = 'do.not.reply@yourdomain.org'

EMAIL_PORT = 587
EMAIL_USE_TLS = True
DEFAULT_FROM_EMAIL = "do.not.reply@yourdomain.org"

E-mail tests are sent to the address defined in environment variable EMAIL_TEST_RECIPIENT.
