## Introduction
## Introducción

The Eloquent ORM included with Laravel provides a beautiful, simple ActiveRecord implementation for working with your database. Each database table has a corresponding "Model" which is used to interact with that table.

Before getting started, be sure to configure a database connection in `app/config/database.php`.

<a name="basic-usage"></a>
## Basic Usage
## Uso básico

To get started, create an Eloquent model. Models typically live in the `app/models` directory, but you are free to place them anywhere that can be auto-loaded according to your `composer.json` file.

<a name="mass-assignment"></a>
## Mass Assignment
## Asignación en masa

When creating a new model, you pass an array of attributes to the model constructor. These attributes are then assigned to the model via mass-assignment. This is convenient; however, can be a **serious** security concern when blindly passing user input into a model. If user input is blindly passed into a model, the user is free to modify **any** and **all** of the model's attributes. For this reason, all Eloquent models protect against mass-assignment by default.

## Touching Parent Timestamps
## Actualizando marcas de tiempo de relaciones padre

When a model `belongsTo` another model, such as a `Comment` which belongs to a `Post`, it is often helpful to update the parent's timestamp when the child model is updated. For example, when a `Comment` model is updated, you may want to automatically touch the `updated_at` timestamp of the owning `Post`. Eloquent makes it easy. Just add a `touches` property containing the names of the relationships to the child model:

## Working With Pivot Tables
## Trabajando con tablas intermedias

As you have already learned, working with many-to-many relations requires the presence of an intermediate table. Eloquent provides some very helpful ways of interacting with this table. For example, let's assume our `User` object has many `Role` objects that it is related to. After accessing this relationship, we may access the `pivot` table on the models:
