Rails 5: How to add folders and files in application template script
I would like to add folders and add files (like my own readme.md) to newly created rails apps using application templates.
In template.rb
require "fileutils"
require "shellwords"
def add_folders
mkdir views/components/buttons
mkdir csv/
end
def add_file
cd csv
touch user.csv
end
def add_readme
rm README.md
touch README.md
inject_into_file("README.md", "New readme..")
end
after_bundle do
add_folder
add_file
add_readme
end
But I don't know how to do it.

FileUtils covers most of what you want. mkdir_p uses the command line mkdir -p command, which makes the full path if the directories don't exist.
IO.write (which File inherits from IO) accepts a file name, and content. No need to delete the old file and touch a new one.
Also, you'll want to make sure you use Rails.root.join with your file paths. It's similar to File.join, in that it helps you build a file path without doubling up your / on accident, but it also returns an absolute file path on your computer. Also, it makes your code OS agnostic because while unix systems use '/' as the folder separator, Windows computers use ''. So, Rails.root.join makes all of that safer.
Here's an example of using it on a unix system:
If Rails.root is '/some/cool/path/here', then Rails.root.join('views','components', 'buttons') would be '/some/cool/path/here/views/components/buttons'.
require 'fileutils'
require 'shellwords'
def add_folders
FileUtils.mkdir_p(Rails.root.join('views', 'components', 'buttons'))
FileUtils.mkdir_p(Rails.root.join('csv'))
end
def add_file
FileUtils.touch('Rails.root.join('csv', 'user.csv'))
end
def add_readme
File.write(Rails.root.join('README.md'), 'New readme..')
end
after_bundle do
add_folder
add_file
add_readme
end

@JunDalisay Be careful with that. You could end up in a bad place if you skip theRails.root.joinpart, because you're now assuming you know what folder you're in. Skipping that part often leads to cases of "well it works on my computer, I don't know why it isn't working on yours". It's best practice to always useRails.root.joinand then use file paths that are relative to the root of your Rails app (like I showed).

Check whether expected directory is present or not, then create it.
dir = "#{Rails.root}/public/folder_1"
FileUtils.mkdir(dir) unless File.directory? dir
Similarly, you can remove directory if present.
file = "#{dir}/alpha.png"
And you can further proceed with File IO in rails.
