Join Kevin Skoglund for an in-depth discussion in this video Basic CRUD, part of Ruby on Rails 4 Essential Training.
…In this chapter, we will learn to add basic actions to our simple CMS project.…Let's review the MVC architecture diagram.…First, we learn to use controllers and views to create dynamic…pages and return them to the browser, then we shifted our focus.…And we learn to interact with the database by creating models and associations.…We worked with those not from a browser but via the Rails console.…Now we need to learn how to work with models in our controllers.…That will allow us to manipulate our database data…from the browser just like we did from the console.…
We'll be able to create, read, update and delete records.…Those four actions are the main ways that we interact with the database.…We use the acronym CRUD for create, read, update and delete.…Because these four database actions are so common in…Rails, we use standard controller actions for implementing them.…You don't have to use these action names but they are the Rails convention.…So let's learn the rules before we start breaking them.…For each element of CRUD, there are two actions associated with it.…
