gqlgen not generating resolvers from custom model

[alexalexyang]

What happened?

I'm trying out the gqlgen getting-started tutorial and I'm stuck at the section "Don’t eagerly fetch the user", where we create a custom model and use go run github.com/99designs/gqlgen generate to generate new resolvers. But the resolvers were not generated.

What did you expect?

It looks like this should be generated in graph/schema.resolvers.go:

func (r *todoResolver) User(ctx context.Context, obj *model.Todo) (*model.User, error) {
	return &model.User{ID: obj.UserID, Name: "user " + obj.UserID}, nil
}

What did you try?

I found this comment saying we should add to resolver: true for the model in gqlgen.yml.

And also this issue for the same problem, which led me to its OP's repo where he solved the problem with a similar pattern.

So I tried different variations of both, one of them like this:

models:
  ...
  Todo:
    model: gqlgen_tutorial/graph/models.Todo
    fields:
      ID:
        resolver: true

Minimal graphql.schema and models to reproduce

graph/model/todo.go

package model

type Todo struct {
	ID     string `json:"id"`
	Text   string `json:"text"`
	Done   bool   `json:"done"`
	User   *User  `json:"user"`
}

gqlgen.yml:

schema:
  - graph/*.graphqls

exec:
  filename: graph/generated/generated.go
  package: generated

model:
  filename: graph/model/models_gen.go
  package: model

resolver:
  layout: follow-schema
  dir: graph
  package: graph
  filename_template: "{name}.resolvers.go"

autobind:
  - "gqlgen_tutorial/graph/model"

models:
  ...
  Todo:
    model: gqlgen_tutorial/graph/model.Todo
    fields:
      ID:
        resolver: true

versions

• gqlgen v0.17.5
• go version go1.18.1 darwin/amd64

I ran into this today as well. The getting started docs are missing some updates. I created a pull request to update the docs to fix the issue. #2147

If you make these changes when following the tutorial every thing should work as expected.
