Hi, I'm Jeffrey. I'm the creator of Laracasts and spend most of my days building the site and thinking of new ways to teach confusing concepts. I live in Orlando, Florida with my wife and two kids.
    1. Run Time 11:42

      First up, we have "one to one" relationships. This is an easy one to picture in your head. What is one thing that a user might be associated with? What about a profile, or an address, or an avatar?

    2. Run Time 11:05

      Now that we have "one-to-one" relationships locked and loaded, let's move on to our next Eloquent relationship: "one-to-many." What might be an example of something a user would have many of? What about posts, or projects, or tasks? You'll reach for this relationship constantly in your daily workflow.

    3. Run Time 19:06

      Many to many relationships are a bit more confusing to understand. Let's break it down by reviewing the common "posts" and "tags" relationship. A one-to-one or one-to-many relationship isn't quite right here. A post will never own a tag. It can be associated with one, sure, but it doesn't own the tag. The same is true in reverse. When we encounter situations such as this, a "many-to-many" relationship is exactly what we need.

    4. Run Time 9:05

      While not nearly as common, the hasManyThrough relationship, when necessary, can prove to be incredibly useful. This relationship type allows you to perform queries across long-distance relationships.

    5. We've made it to the scariest of Eloquent relations: polymorphic. Don't worry! As with most things, the word is scarier than the technique. A polymorphic relationship allows a model to belong to any number of models on a single association. Let's demonstrate this with a practical example.

    6. We've finally made it to the most intimidating of Eloquent relationships: many to many polymorphic. Don't worry; it's far simpler to understand than you might initially think. In this lesson, we'll construct a standard many-to-many relationship: a user can "like" a post. Then, we'll throw a wrench into the mix. What if a user can also "like" a comment? How might we restructure our existing structure to allow for this?
