⚙️ Setting up a PostgreSQL user

If you don't have a user set on postgres, here's how to set new user:

sudo -u postgres createuser -s [username]

To set a password for this user, log in to the PostgreSQL command line client:

sudo -u postgres psql

Enter the following command to set the password:

\password your_password

Enter and confirm the password. Then exit the PostgreSQL client:

📋 Execution

Run the following commands to execute locally:

The following will install required version of ruby (make sure rvm is installed.)

rvm use 2.7.2

git clone git@github.com:JuzerShakir/rails-authenticate.git

cd rails-authenticate

bundle install

💡 Imp Note:

To successfully create development and test database, you will need to update config.database.yml file with correct postgresql username and password. To edit the it without exposing your credentials, give the following command:

EDITOR="code --wait" rails credentials:edit

code for Visual Studio Code subl for sublime

This will open credential.yml file and enter credential as follows in it:

database:
  username: your_username
  password: your_password

Hit ctrl + s to save and then close the credential.yml file from the editor. This will save the credentials. To check if it did save, run the following inside rails console:

Rails.application.credentials.dig(:database, :username)

rails db:create

Also .env file has been added to .gitignore file. You should create a similar file named .env at the root of this directory and fill the following environment variables value with yours:

GMAIL_USERNAME = your_email
GMAIL_PASSWORD = your_password
RECAPTCHA_SITE_KEY = your_key
RECAPTCHA_SECRET_KEY = your_secret_key
