This course is a comprehensive tutorial that will teach you the best way to build your next API with Rails. You’ll learn to create a Rails API from scratch and to optimize and secure a Rails API. By the end of this course, you’ll have a full-fledged Rails API ready to be used.

Building your own API with Rails

# Generate the model
The `Order` model is associated with users and products simultaneously.

Thankfully, it is easy to achieve this in Rails. The tricky part is when it comes to serializing this object. We’ll talk more about this later.

We will generate the `Order` model using the `generate model` command:

```
$ rails generate model order user:belongs_to total:decimal
```
We use the `references` method to create the corresponding foreign key for the order to belong to a user. It also adds the `belongs_to` directive into the `Order` model. Let’s generate the model using this command in the terminal below:

Generate the Order model, which will be used to update the total calculation for orders.
