How to manage relationships with AshGraphql

I have a Resource called WebSite that has_many :components, and each is a WebComponent. This test failed: 
test "success creating a WebSite", ctx do
  input = %{
    attrs: [%{title: "Test Site", key: "test_site"}],
    components: [%{type: "html", value: "test"}]
  }

  resp_body = post_gql(ctx, query: @create_web_site, variables: %{input: input})

  %{
    "data" => %{
      "createWebSite" => %{
        "result" => result,
        # Argument "input" has invalid value $input. In field "components": Expected type "[JsonString!]"
        "errors" => []
      }
    }
  } = resp_body
end
test "success creating a WebSite", ctx do
  input = %{
    attrs: [%{title: "Test Site", key: "test_site"}],
    components: [%{type: "html", value: "test"}]
  }

  resp_body = post_gql(ctx, query: @create_web_site, variables: %{input: input})

  %{
    "data" => %{
      "createWebSite" => %{
        "result" => result,
        # Argument "input" has invalid value $input. In field "components": Expected type "[JsonString!]"
        "errors" => []
      }
    }
  } = resp_body
end
In the list of components in the input, does each component need to be individually JSON-encoded? Apparently it does, because when I encode the component, the test passes. Why would this need to be JSON-encoded? Is this documented somewhere? I didn't see mention of it.

You need to specify the managed relationship in the graphql dsl: https://ash-hq.org/docs/dsl/ash-resource#graphql-managed_relationships-managed_relationship
Ash HQ
Ash.Resource
View the documentation for Ash.Resource on Ash HQ.

Got it. thanks @Zach Daniel ! One thing about that page you referenced. The page is for the Ash.Resource DSL, and the information in it is about AshGraphql. I never would have expected to find direct info about AshGraphql inside the Ash.Resource documentation.

Yeah, so we combined it to be about the entity that the DSL belongs in. I can see how that would be confusing

Did you find this page helpful?
