System Fields

All default, and custom content types come with some managed system fields. These fields reflect certain states of your content, such as when it was last updated, or published at.

Default model fields

These fields are included with all content models you create within GraphCMS.

Asset fields

Since the Asset model is included with every project, it also comes with some predefined fields, as well as all of the system fields above.

The Asset field type has all of the default fields, as well as:

Asset fields are localized by default, and always include the localization fields described below.

Localization fields

When you localize fields within GraphCMS, the model will be updated to contain the following fields:

Version history fields

One of the auto-generated queries GraphCMS will create is around versioning. Each time you publish content to a stage, a version is saved.

You can fetch the version history of a content entry by using the history field on a model. This field is managed automatically by GraphCMS.

{
  posts {
    id
    title
    history {
      id
      stage
      revision
      createdAt
      data
    }
  }
}

Connection type fields

Since GraphCMS implements the Relay specification, when fetching with Relay you will have some fields made available to you automatically.

For example, let's imagine we have the model Post. The postsConnection would look a little something like:

[PostEdge!]!

{
  postsConnection {
    edges {
      cursor
      node {
        id
        title
      }
    }
  }
}

PageInfo!

GraphCMS exposes the PageInfo type on the field pageInfo for connection queries. This is useful with cursor based pagination.

{
  postsConnection {
    pageInfo {
      hasNextPage
      hasPreviousPage
      startCursor
      endCursor
      pageSize
    }
  }
}

Aggregate!

It is possible using the connection type query to perform an aggregate count.

{
  postsConnection {
    aggregate {
      count
    }
  }
}
