Test Environment

Running Tests

To run the main test framework, first install all the dependencies, then run the tests:

cpanm --installdeps .
prove -lr

To run the main framework against a PostgreSQL backend, assuming you have postgres installed, you will need some extra dependencies first:

cpanm --installdeps . --with-feature postgres
PEAR_TEST_PG=1 prove -lr

Setting Up Minion

To set up Minion support, you will need to create a database and user for it to connect to. In production his should be a PostgreSQL database, however SQLite can be used in testing.

To use the SQLite version, run the following command:

cpanm --installdeps --with-feature sqlite .

And then ensure that the following is in your configuration file:

  minion => {
    SQLite => 'sqlite:minion.db',
  },

This will then use an SQLite DB for the Minion backend, using minion.db as the database file. To start the minion itself, run:

./script/pear-local_loop minion worker

Importing Ward Data

To import ward data, download CSV(s) from here and then run the following command:

./script/pear-local_loop minion job \
  --enqueue 'csv_postcode_import' \
  --args '[ "⟨ path to CSV ⟩ ]'

Setting Up Entity Postcodes

1. Import Code-Point Open:
   • included in etc/
   • ./script/pear-local_loop codepoint_open --outcodes LA1
2. Assign postcodes:

./script/pear-local_loop minion job \
  --enqueue entity_postcode_lookup

Example PostgreSQL setup

# Example commands - probably not the best ones
# TODO come back and improve these with proper ownership and DDL rights
sudo -u postgres createuser minion
sudo -u postgres createdb localloop_minion
sudo -u postgres psql
psql=# alter user minion with encrypted password 'abc123';
psql=# grant all privileges on database localloop_minion to minion;

Development Environment

There are a couple of setup steps to getting a development environment ready.

First Time Setup

1. Decide if you're using SQLite or PostgreSQL locally.
   • Development supports both, however production uses PostgreSQL.
   • For this example we will use SQLite.
   • As the default config. is set up for this, no configuration changes are needed initially.
2. Install dependencies:
   • cpanm --installdeps . --with-feature=sqlite --with-feature=codepoint-open
3. Install the database:
   • ./script/deploy_db install -c 'dbi:SQLite:dbname=foodloop.db'
4. Set up the development users:
   • ./script/pear-local_loop dev_data --force
   • DO NOT RUN ON PROD.
5. Start the minion:
   • ./script/pear-local_loop minion worker
6. Import ward data (see Production instructions above)
7. Set up postcodes (see Production intructions above)
8. Start the application:
   • morbo script/pear-local_loop -l http://*:3000
   • You can modify the host and port as needed.

Database Scripts

To upgrade the database after making changes to commit:

./script/deploy_db write_ddl -c 'dbi:SQLite:dbname=foodloop.db'
./script/deploy_db upgrade -c 'dbi:SQLite:dbname=foodloop.db'

To redo leaderboards:

./script/pear-local_loop recalc_leaderboards
