An example of an AI chatbot conversation about the Rails dotenv gem for managing environment variables.
What is the Rails dotenv gem and how do I use it?
The Rails dotenv gem is a tool that helps you manage environment variables in your Rails applications. It allows you to store sensitive information like API keys in a .env file, which is not included in version control.
How do I install the dotenv gem in my Rails project?
You can install the dotenv gem by adding gem 'dotenv-rails' to your Gemfile and then running bundle install.
Can you show me an example of how to create a .env file?
Sure! Just create a file named .env in the root of your Rails project and add your variables like this:
DATABASE_URL=postgres://user:password@localhost/dbname
API_KEY=your_api_key_here
How do I access these variables in my Rails application?
You can access the variables using ENV['VARIABLE_NAME']. For example, ENV['API_KEY'] will give you the value of API_KEY from your .env file.
