And modern database engines can index and natively query inside these JSON structures quite well. standard data structures, and the Document Object Model (DOM). JSON columns effectively give us the benefits (and downsides) of a NoSQL/document-based database inside our relational database. JavaScript often abbreviated as JS, is a programming language that is one of the core. There are plenty of reasons why you may want to consider a JSON column. Maybe we have a collection of items that aren't deserving of their own table. Dynamic properties allow you to access relationship methods as if they were properties defined on the model: phone User::find(1)->phone. The Laravel docs has an excellent example of how we can cast to and from multiple columns into a single value object.īut in some cases we may want a nested structure, or maybe we have a lot of optional fields that we don't want cluttering the table structure. this tutorial we will see the use of Eloquent Pluck method to fetch specific key values from model and. We could create dedicated columns in the database for each attribute. Ive tried changing the wire:model in the blade. However, the database won't be able to query the parts easily, and depending on the number of type of attributes, it could get unwieldy. So we may be tempted to create our own conventions. We may not always be so lucky with our value objects though. For example, a date can represent the year, month, and day as Y-m-d but we can still pull it apart if needed, and the database knows how to query the parts individually. Some may have have special formats that allow us to represent the individual attributes as a single string. That's part of what separates them from primitive types like strings and integers. Most value objects have multiple attributes. $user ->address-> calculateDistance ( $otherUser ->address )
