Heroku Database Setup

Setting Up The Database

• head to the heroku dashboard for your project

• go to the resources tab

• provision a free heroku postgres database

• go the database dashboard, under settings you'll find the database credentials

• use those credentials to add the following heroku config vars

DB_HOST
DB_PORT
DB_DATABASE
DB_USERNAME
DB_PASSWORD

• you'll see a command like this that will let us access the psql shell for the database so we can create our table. heroku pg:psql postgresql-objective-XXXX --app projectname

• create your tables

• in connection.dart add useSSL in the list of arguments this.conn = PostgreSQLConnection(host, port, database, username: username, password: password, useSSL: true); and push your code again your api will be deployed!

DATABASE CONNECTION

Environment Variables for Database Settings

• DB_HOST
• DB_PORT
• DB_DATABASE
• DB_USERNAME
• DB_PASSWORD

These can be changed in connection.dart

the test.dart file in connection folder is a good tool for testing out database queries and your models

Models

A Sample model is in the models folder that you can copy to create your own by modifying their methods as needed.

follow the patterns in initiateModel and the /getall route in testController to see how to use your model in your routes.

Migrations

I'm using the raw postgres drivers, so no migrations. So you'll need to create the database and tables for your models to work.
