Support multiple data formats with one struct

[hboylan]

What happened?

My resolver returns JSON data using snake case, but my GQL data adheres to the standard camel case format. This forces me to define 2 separate types for each model in order to support the schema for my resolver and GQL client.

What did you expect?

The documentation mentions the use of a gqlgen struct tag to bind tags, but the json tag appears to override this feature. Basically, I expected the ability to define one model to support data in (json) and data out (gqlgen).

expected models.go

type Account struct {
	ID              int       `json:"id"`
	Name            string    `json:"name"`
	CreatedAt       time.Time `json:"created_at" gqlgen:"createdAt"`
	CreatedBy       string    `json:"created_by" gqlgen:"createdBy"`
}

Minimal graphql.schema and models to reproduce

schema.graphql

type Account {
  id Int!
  name String!
  createdAt String!
  createdBy String!
  ...
}

type Query {
  accounts: [Account!]!
}

models.go

type Account struct {
	ID              int       `json:"id"`
	Name            string    `json:"name"`
	CreatedAt       time.Time `json:"created_at"`
	CreatedBy       string    `json:"created_by"`
}

type GQLAccount struct {
	ID              int       `json:"id"`
	Name            string    `json:"name"`
	CreatedAt       time.Time `json:"createdAt"`
	CreatedBy       string    `json:"createdBy"`
}
