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.

In this example, we are taking a property content (which will be defined as Content in PHP) and defining it as pageContent for GraphQL queries and mutations.

# app/_graphql/models.yml
Page:
  fields:
    pageContent:
      type: String
      property: Content

When using explicit property mapping, you must also define an explicit type, as it can no longer be inferred.

Dot-separated accessors

Property mapping is particularly useful when using dot syntax to access fields.

# app/_graphql/models.yml
App\PageType\Blog:
  fields:
    title: true
    authorName:
      type: String
      property: 'Author.FirstName'

Fields on has_many or many_many relationships will automatically convert to a column array:

# app/_graphql/models.yml
App\PageType\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
App\Model\ProductCategory:
  fields:
    title: true
    productCount:
      type: Int
      property: 'Products.Count()'
    averageProductPrice:
      type: Float
      property: 'Products.Avg(Price)'
