Nomad

Getting Started

1. Check out the code

   git clone [email protected]:RagtagOpen/nomad.git
   

2. Go into the checked out repository

   cd nomad

3. Local Variables

   Create a file for your local environment variables. This file should be called .env and live at the root of the nomad project directory.

   touch .env
   echo FLASK_APP=wsgi.py >> .env
   echo FLASK_DEBUG=1 >> .env

4. Add a SECRET_KEY to your .env. The value for SECRET_KEY can be any value for the purposes of local development.

    echo SECRET_KEY=your_secret_key >> .env

5. (Optional) Get a Google Maps Api Key

   In order to run the search frontend you will need an API key for Google maps. You can get one here. On the "Enable Google Maps Platform" page choose "Maps" as the product. Then set the key as a variable in your .env file.

   echo GOOGLE_MAPS_API_KEY=YOUR_KEY_HERE >> .env

6. (Optional) Configure Google Sign-In In order to test Google authentication you'll need to create a Console Project.
   For "Where are you calling from?" choose "Web server".
   For "Authorized redirect URIs" enter http://localhost:5000/callback/google.
   After creating credentials you'll get an OAuth Client ID and Client Secret.

   echo GOOGLE_CLIENT_ID=YOUR_CLIENT_ID >> .env
   echo GOOGLE_CLIENT_SECRET=YOUR_CLIENT_SECRET >> .env

7. Configure Email Send In order for the app to send email, you'll need to add details about what mail server it should use. For testing, you can use a Mailgun or Gmail account. Add those details to the .env file, too!

echo MAIL_SERVER=smtp.mailgun.org >> .env
echo MAIL_PORT=465 >> .env
echo MAIL_USE_SSL=1 >> .env
echo MAIL_USERNAME=your_username >> .env
echo MAIL_PASSWORD=your_password >> .env

If you want to test emails without actually sending them, you can use MailDev with Docker and the following .env configuration:

echo MAIL_SERVER=fakesmtp >> .env
echo MAIL_PORT=25 >> .env
echo MAIL_USE_SSL=0 >> .env

With that setup, you can run docker-compose up nomad fakesmtp and view emails at http://localhost:8081/.

Running with Docker Compose

You can get up and running with Docker and Docker Compose. This will allow you to get up and running quickly while installing a smaller set of dependencies to your computer.

1. Install Docker

   This will install Docker and Docker Compose. That should be everything you need.

2. Build the project

   This will build the Docker images that you can use for local development

   # Make sure you're at the root of the nomad project
   # Build the images. This will likely take a few minutes
   # the first time as it needs to download a few images from the Docker registry
   docker-compose build

3. Run the project

   This will set up your database, run migrations, and start the application server for you.

   docker-compose up nomad nomad_worker

4. Browse to http://127.0.0.1:5000/ in your browser to check it out.

5. (Optional) Taking more direct control

   If you actually want to drop into a bash prompt in the nomad container you can execute to following command.

   docker-compose run --service-ports nomad bash

Misc. notes on developing Nomad in Docker

On requirements

If Pipfile changes, a docker-compose build will reinstall all Python dependencies

Accessing the DB

To connect to the DB in docker, run:

docker-compose run --service-ports nomad "psql postgresql://nomad:nomad@db/nomad"

Setting environment variables

.env does not get directly source'd to the application context; rather, it's used to populate docker-compose.yml, which can then be used to set environment variables in the applicaiton context. Therefore, if you add an environment variable in .env that you want the app to be able to access, you must also add it in the environment block of docker-compose.yml.

Running on Localhost

1. Install pipenv

   brew install pipenv

   or

   pip install pipenv

2. Install the database. The app requires PostgreSQL and PostGIS. This guide describes how to get PostgreSQL running on your computer.

   When you have PostgreSQL installed, you need to create a database for the data to go. Use the psql command to connect to your PostgreSQL instance:

   psql
   # psql (9.6.1, server 9.5.4)
   # Type "help" for help.

   Create the database and add the PostGIS extension:

   create database carpools;
   # CREATE DATABASE
   \connect carpools
   # psql (9.6.1, server 9.5.4)
   # You are now connected to database "carpools" as user "iandees".
   create extension postgis;
   # CREATE EXTENSION
   \quit

3. Install the Python dependencies.

   pipenv install
   pipenv shell

4. Set up the database

   source .env
   flask db upgrade

5. Run the Flask application

   source .env
   flask run

6. Browse to http://127.0.0.1:5000/ in your browser to check it out.

Adding the first admin user

Once you have the app running with Docker or locally, you need to add your first admin user.

1. With the app running, visit the login page in your browser and login with Facebook or Google.

2. In a console, bring up a Flask shell:

   If you used Docker:

   docker-compose run --service-ports nomad flask shell
   

   If you are running the app locally:

   # Make sure you've activated your virtual environment
   source venv/bin/activate
   # Run the flask shell
   source .env
   flask shell
   

3. Add an admin Role to your single Person instance:

   from app.models import Role, Person
   from app import db
   r = Role(name='admin', description='Administrator')
   db.session.add(r)
   p = Person.query.first()
   p.roles.append(r)
   db.session.commit()
   

4. Visit http://127.0.0.1:5000/admin to verify your account now has the appropriate role.

Running tests

Using Docker:

```
docker-compose run nomad pytest
```

Locally:

```
pytest
```

Branding

Organizations using Nomad need to set these environment variables:

• BRANDING_ORG_NAME - organization name; default "Ragtag"
• BRANDING_ORG_SITE_NAME - site name (not full URL), default "ragtag.org"
• BRANDING_LIABILITY_URL - URL to organizer liability statement (required)
• BRANDING_EMAIL_SIGNATURE - default "The Nomad team"
• BRANDING_SUPPORT_EMAIL - default [email protected]

These environment variables have reasonable defaults; setting these is optional:

• BRANDING_CSS_URL - URL to CSS with skin-specific overrides; default is no overrides
• BRANDING_HEADLINE_1 - default "Carpool to canvass in battleground districts near you"
• BRANDING_HEADLINE_2 - default "Find other volunteers near you and join a carpool."
• BRANDING_PRIVACY_URL - default /terms.html; the default terms.html uses values of BRANDING_ORG_NAME, BRANDING_ORG_SITE_NAME, and BRANDING_SUPPORT_EMAIL

sample Swing Left branding

to use sample sample config for Swing Left locally:

cat branding/swing-left >> .env

sample branding config values: branding/swing-left

sample CSS overrides: static/css/swing-left.css

restart app to reload config from .env

branding QA

• BRANDING_ORG_SITE_NAME in terms.html ie "nomad.ragtag.org, the "Site""
• BRANDING_SUPPORT_EMAIL in terms.html ie "email [email protected]"
• BRANDING_LIABILITY_URL in email templates: driver_reminder, ride_approved.html
• BRANDING_EMAIL_SIGNATURE in all email templates
• logo on home page, defined in CSS referenced by BRANDING_CSS_URL
• BRANDING_HEADLINE_1 and BRANDING_HEADLINE_1 on home page, below "SHARE YOUR RIDE"
