Postgres: Nested object queries

Introduction​

You can use the object (one-to-one) or array (one-to-many) relationships defined in your schema to make a nested query i.e. fetch data for a type along with data from a nested or related type.

The name of the nested object is the same as the name of the object/array relationship configured in the console.

You can also filter, sort, aggregate and paginate nested objects in case of array relationships. These are not exposed for object relationships as they have only one nested object.

Fetch nested object using an object relationship​

The following is an example of a nested object query using the object relationship between an article and an author.

Example: Fetch a list of articles and the name of each article’s author:

Fetch nested objects using an array relationship​

The following is an example of a nested object query using the array relationship between an author and articles.

Example: Fetch a list of authors and a nested list of each author’s articles:

You can also filter, sort, aggregate and paginate nested objects in case of array relationships.
