Note: RAILS_ROOT is the Rails root directory. This is done using the database.yml file, located at: We will now configure which database Rails will talk to. Rails expects the name of the database user to match the name of the application, but you can easily change that if need be.
This creates a directory called “myapp” which houses an app called “myapp” (you can name it anything you like when running the command). To create a Rails app configured for Postgres, run this command: rails new myapp -database=postgresql
#Setting up adventureworkslt database in postgresql password
Then create a user (or a “role”, as Postgres calls it): create role myapp with createdb login password 'password1' To do this, switch into the Postgres user: su - postgres
#Setting up adventureworkslt database in postgresql install
To do so: gem install pgĬreate a Postgres user for the Rails app we’ll create in the next step. pgAdmin isn’t the prettiest tool in the world, but it does the job.įinally, you’ll want to install the pg gem so that you can interface with Postgres from Ruby code. If you are installing Postgres on a local machine you may also want to install a GUI (though this guide assumes command line usage). Generally it’s easiest to use a package manager such as apt-get on Ubuntu or Homebrew on OS X. The method of installing Postgres depends on your OS. This will install Rails and any other gems it requires. Instead you can simply install Rails by installing the gem: gem install rails If you already have RVM installed, you don’t need to re-install it. This is useful as you may require different versions of Ruby for different projects. You can now use it to manage your Ruby versions. Note: you should review the RVM install script before running it (or any other remote script that you pipe into bash. To do so, run this command: \curl -L | bash -s stable -rails RVM can install Ruby and Rails automatically as part of its installation.
If you already have RVM installed, skip to the next section. To install RVM you will need to ensure your system has curl installed (how you do this depends on your OS).
The easiest way to install Rails is using RVM, which also installs Ruby. You can follow the guide on your local machine or a VPS. This guide will step you through creating a Rails application that uses a Postgres database. By default it assumes that MySQL is being used, but it’s quite easy to use with Postgres instead. Rails is database agnostic, meaning it can be used with a variety of different databases. Ruby on Rails is an open source web framework written in Ruby. Postgres (or PostgreSQL) is an open source database.
