Did you know that Rails has a
Similar to your
~/.zshrc file, you can use this file to configure your Rails applications.
This is especially useful if you find yourself repeatedly typing
--no-skip commands and installing specific gems every time you create a new Rails application.
Since I made a switch to Rails from .NET last year, I must have created at least 20-30 projects for either learning, experiments, or client work. I have a text file that documents all the gems I want to install for a fresh Rails app. Every time I create a new project, I go through the file to install all the gems I want for my project.
~/.railsrc file, I don't need to do that. Rails will do it for me. Here's how you do this.
First, create the
.railsrc file in your home directory.
Add whatever options you want in this file. For example,
To see all the available options, type
rails in a non-rails directory.
➜ rails rails Usage: rails new APP_PATH [options] Options: [--skip-namespace], [--no-skip-namespace] # Skip namespace (affects only isolated engines) [--skip-collision-check], [--no-skip-collision-check] # Skip collision check -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /Users/akshay/.rbenv/versions/3.1.0/bin/ruby -m, [--template=TEMPLATE] # Path to some application template (can be a filesystem path or URL) -d, [--database=DATABASE] # Preconfigure for selected database ...
To pre-configure the gems you'd like to install, create a
template.rb file. Here's mine:
gem_group :development, :test do gem 'dotenv-rails' gem 'factory_bot_rails' end gem_group :development do gem 'better_errors' gem 'binding_of_caller' gem 'annotate' end
Now add the path to the template at the end of your
That's it. The next time you run
rails new app, Rails will use the configuration file along with the
Gemfile template to create your application just like you want.
Pretty cool, right?
