An example of an AI chatbot conversation about using environment variables in Rails.
How do I use environment variables in a Rails application?
You can use the dotenv gem to manage environment variables in your Rails app. First, add it to your Gemfile.
What do I need to do after adding the dotenv gem?
After adding the gem, create a .env file in the root of your project and define your variables there, like DATABASE_URL=your_database_url.
How do I access these variables in my code?
You can access the environment variables using ENV['VARIABLE_NAME']. For example, ENV['DATABASE_URL'] will give you the database URL.
Is it safe to store sensitive information in the .env file?
Yes, but make sure to add the .env file to your .gitignore to prevent it from being pushed to version control.
