CRUD Examples

This page is a follow-up to How to Create, Retrieve, Update, and Delete Objects in FaunaDB. Here you will find further examples of working with objects in FaunaDB including databases, keys, classes, user-defined functions, and indexes.

Database Examples

Reading or writing instances of databases requires an admin key.

Create a Database

curl https://db.fauna.com/ \
    -u fnACrVIq8BACAHNB8hzHWDxMpcYiQkJgPKtZGtIn: \
    -d '{ "create_database": { "object": { "name": "annuvin" } } }'

var adminClient = new FaunaClient(secret: adminKey);

adminClient.Query(CreateDatabase(Obj("name", "annuvin")));

FaunaClient adminClient = FaunaClient.builder()
  .withSecret(adminKey)
  .build();

System.out.println(
        adminClient.query(CreateDatabase(Obj("name", Value("annuvin")))
        ).get());

adminClient := f.NewFaunaClient(adminKey)

result, _ := adminClient.Query(f.CreateDatabase(f.Obj{"name": "annuvin"}))

fmt.Println(result)

val adminClient = FaunaClient(secret = adminKey)

adminClient.query(CreateDatabase(Obj("name" -> "annuvin")))

adminClient = FaunaClient(secret=adminKey)

adminClient.query(q.create_database({"name": "annuvin"}))

$admin_client = Fauna::Client.new(secret: adminKey)

$admin_client.query do
  create_database name: 'annuvin'
end

let adminClient = FaunaDB.Client(secret: adminKey)

adminClient.query(CreateDatabase(Obj("name" => "annuvin")))

var adminClient = new faunadb.Client({
  secret: adminKey
});

adminClient.query(q.CreateDatabase({ name: "annuvin" }))
  .then((ret) => console.log(ret))

User-Defined Function Examples

Creating and updating a function requires a server key.

Create a User-Defined Function

Let’s create a function to allow our authors to create new blog posts. We’ll set it up to allow the author to provide a title and body. This way authors are constrained by what data they can store on a post instance.

Index Examples

Creating and updating an index requires a server key.

Create an Index

Indexes can also cover multiple values, which affect the order of their results. See below section on ordering for more information.

Here is an example of an index that allows you to search for a spell by its element and get back both the spell name and ref:

Indexes with Ordering and Transformations

Let’s create an index to return the latest spells updated. To do this we will create an index which is sorted reversely by each spell’s last updated timestamp.

We’ll specify terms on this index so we can find spells by element. We’ll also use the casefold function as a transformation to the specified term which will make the entries lowercase in the index.

Since timestamp was added to the index to facilitate sorting, it might not be required for the query to return timestamp values to the application layer. In that case, it’s possible to use the map function to extract only the desired fields.

Update an Index

It is disallowed to update an index in a way that changes its shape. This means no changing the source or the terms. You can, however, change the name of an index or its uniqueness. If you update the unique field, it will not remove existing duplicated items from the index.
