Resolver method to nested model not created

[marczahn]

Expected Behaviour

For a relation Card -> Question I expect in the card resolver a method like

func (r *cardResolver) Question(ctx context.Context, obj *models.Card) (models.Question, error) {
	panic("not implemented")
}

Actual Behavior

There is no method for this

Minimal graphql.schema and models to reproduce

same configuration as here

[marczahn]

I just found out that the resolver method is created as soon as the sub entity is specified as a list in the graphql.schema.

Is this a bug or is there a reason why it is like this?

If you want a resolver method when generating models use resolver: true.

eg:

models:
  Todo:
    fields:
      id:
        resolver: true # force a resolver to be generated

see https://gqlgen.com/config/

Hey @vektah
thank you! It is working indeed - I overlooked this. Nevertheless: It is unexpected that there are resolvers created for lists per default.

I agree with @marczahn here, I spent a pretty long time scratching my head as to how to deal with nested models, and this doesn't seem very clearly documented.

Also the nested model in the example https://github.com/99designs/gqlgen/blob/master/example/starwars/schema.graphql#L33 doesn't seem to have the resolver: true directive in its config for friendsConnection: https://github.com/99designs/gqlgen/blob/master/example/starwars/.gqlgen.yml

Could you clarify this a little @vektah ? thanks!

Two years later, it still took me a full day of reading gqlgen docs (finding nothing) and finally Googling to find this issue and realize that generated nested models don't automatically create resolvers.

@vektah @frederikhors I've seen you mention a couple places that the docs explain how to do this, but it's still VERY confusing (as can be seen by the number of confused devs opening these issues still). It seemed completely broken for me.... had no idea why it wasn't working. Maybe could update the docs to better explain what's needed to generate resolvers? I'd recommend a section describing resolver generation here (not mentioned anywhere there): https://gqlgen.com/config
