ソース

使い方

1 プロジェクトをclone
2 プロジェクト名を変更
3 application.rbを修正

config/application.rb

require_relative 'boot'

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module RailsDevice # ←ここを任意のプロジェクト名へ
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.
  end
end

4 session_store.rbを修正

config/initializers/session_store.rb

# Be sure to restart your server when you modify this file.

Rails.application.config.session_store :cookie_store, key: '_rails-device_session'# アプリ名の部分を変更

5 database.ymlを修正

config/database.yml

# MySQL. Versions 5.0 and up are supported.
#
# Install the MySQL driver
#   gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
#   gem 'mysql2'
#
# And be sure to use new-style password hashing:
#   http://dev.mysql.com/doc/refman/5.7/en/old-client.html
#
default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: root
  password:
  host: localhost

development:
  <<: *default
  database: rails-device_development # アプリ名の部分を変更する

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: rails-device_test # アプリ名の部分を変更する

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
#   DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
#   production:
#     url: <%= ENV['DATABASE_URL'] %>
#
production:
  <<: *default
  database: rails-device_production # アプリ名の部分を変更する
  username: rails-device # アプリ名の部分を変更する
  password: <%= ENV['RAILS-DEVICE_DATABASE_PASSWORD']  # アプリ名の部分を変更する%>
