Working with DataObjects
[CHILDREN asList]
[alert] You are viewing docs for a pre-release version of silverstripe/graphql (4.x). Help us improve it by joining #graphql on the Community Slack, and report any issues at github.com/silverstripe/silverstripe-graphql. Docs for the current stable version (3.x) can be found here [/alert]
Property mapping and dot syntax
For the most part, field names are inferred through the DataObject model, but its API affords developers full control over naming:
app/_graphql/models.yml
Page:
fields:
pageContent:
type: String
property: Content
[notice] When using explicit property mapping, you must also define an explicit type, as it can no longer be inferred. [/notice]
Dot-separated accessors
Property mapping is particularly useful when using dot syntax to access fields.
app/_graphql/models.yml
MyProject\Pages\Blog:
fields:
title: true
authorName:
type: String
property: 'Author.FirstName'
Fields on plural relationships will automatically convert to a column array:
app/_graphql/models.yml
MyProject\Pages\Blog:
fields:
title: true
categoryTitles:
type: '[String]'
property: 'Categories.Title'
authorsFavourites:
type: '[String]'
property: 'Author.FavouritePosts.Title'
We can even use a small subset of aggregates, including Count(), Max(), Min() and Avg().
app/_graphql/models.yml
MyProject\Models\ProductCategory:
fields:
title: true
productCount:
type: Int
property: 'Products.Count()'
averageProductPrice:
type: Float
property: 'Products.Avg(Price)'
