CRUD new1

In this course, you will learn the fundamentals of Ruby on Rails to build your own application.

You will start by learning how to create a new project, deploy to a Rails server, and the Rails design pattern. After that, you’ll learn how to perform CRUD operations, handle user authentication, and manage sessions.

Once you finish this course, you’ll have the foundations in place to build more complex applications to add to your portfolio.

Introduction to Ruby on Rails

## Create
In the previous lesson, you created a model named `Pet` and used the `create_table` method to create the `pets` table for this model with attributes *name* and *age*. Active Record provides you with two methods to set values for these attributes. These commands will be executed inside the *rails console* for now. In later lessons, you will learn to make updates to the database using web forms.

You can enter the *rails console* by using the command:
```
rails c
```

### new
The first method is by using the `new` command. This command instantiates a new object without saving it into the database. You can set the values for each attribute in separate commands.
