Ruby on rails backend project

MVC architecture

Models are databases (schema) View are webpages controller are brain behind the scene business logic written here

apps

assets (css, js, images files) for webpages views (web pages are built here)

config

routes file where (routes for webpages are created)

rails generate create webpage

creating webpage in rails

rails g controller home index

manual way in app/views/home create a file - filename.html.erb

go to controllers/home_controller create a blank method

def about
end

and create a route in config/route

get 'home/about'

can visit this page using this url home/about

rails generate scaffold

rails g scaffold friends first_name:string last_name:string email:string phone:string twitter:string

After this need to do db migrate to push this changes of models into database

rails db:migrate

rails routes

after this steps perform steps provided in console later from documentation do this adding devise model as uesr

rails generate devise user
