Collections are a very powerful feature because they allow us to access multiple items at the same time. However, in many situations we do not want to access all the entities of a given type, but only the ones that meet some specific criteria. In order to reduce the set of entities in the collection to the ones we care about, we use filters.
In this tutorial we will:
- Look at the
filterquery string parameter and how it can be used with JSON API collections
- Learn how to use filters in combination with the JSON API module for Drupal to reduce the list of entities in a collection
By the end of this tutorial you should be able to request a list of entities in the form of a JSON API collection and filter that list to include only the entities that match a specific set of requirements.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
