Hello folks, I am trying to generate only Go types from schema.graphql. Is there a way to achieve that? If I don't have resolver and generated entries in my gqlgen.yaml, gqlgen generates generated and resolver.

Is there a specific configuration for this?

Edit: The use case is to generate types for go clients

Thanks in advance

Hi, is there a way to omitempty(i.e not send nil/empty fields back in response) ? I tried a model hook to add omitempty to json tag of generated models but that doesnt prevent sending out nil/empty fields as "null" value in response

Is there a way to grab the operation execution time from the OperationContext? TIA
Randy Lough
@randallmlough
Is there a good way to add to the ast.Path, like an index? One of my operations is a bulk operation that takes a slice of elements. If there's an error I'd like to append the index of element where the error occurred. As of right now only the general path to the resolver is returned
@bhaskarsaraogi_twitter add omit_slice_element_pointers: true to your gqlgen.yml file
Randy Lough
@randallmlough
@bhaskarsaraogi_twitter on non slice elements I'm not sure if you can since GraphQL by design you return the requested fields, so if you omit one that was requested, you're breaking the rules. I could be wrong on that, but that was always my understanding

I think I got the ast.Path to work for now using a makeshift appender using context
Randy Lough
@randallmlough
Another question: is there a hook / middleware I can leverage that is called right before the response is sent? AroundOperations seems to be called first, then AroundResponses and then AroundFields, but this can be called multiple times. I'm looking for a hook that is called once and at the very end. My use case is I have nested mutations, and if a nested mutation fails I would like to rollback. So I would start the transaction at the start of the request and if there's an error anywhere in the request/operation I can rollback otherwise commit. If anyone has any suggestions on how to implement that I would appreciate it

Hi everyone. I'm having a bit of a weird issue that I'm trying to narrow down. Every so often (can be within days, hours or within 30 minutes) I start getting 'too many open files' log messages in syslog. When I run lsof, I see hundreds of sock connections to my gqlgen-based server. I've already changed the open-files limit on my OS. I have 3 subscriptions, my app is private and only developers are connecting to it. It "feels" like the websocket part of my server is not closing these connections. Has this happened to any of you, or do you have any tips for me?

Hello everyone!
Is it possible to force gqlgen to throw an error when there is a mismatch between enum values between the resolver response and the schema?
Currently, if the resolver returns enum field with a value that is different from schema definition, it silently renders it into the response without any error.
Is it expected behavior? Should the validation logic for enum be implemented separately?

Anyone got any examples of testing resolvers? ideally unit testing i guess...

Hi!

Say I have a custom ID implementation (called GlobalID), but my models all contain a string ID. Can I point gqlgen into a function that converts a string to GlobalID
instead of it generating ID resolvers for every model?

Alik Send
@aliksend

@yuvalt7 better yet https://gqlgen.com/reference/scalars/#custom-scalars-with-third-party-types
use

models:
  ID:
    model: path/to/your/file.GlobalID

and in file implement MarshalGlobalID and UnmarshalGlobalID functions

Alik Send

Hi. I created fix for #965 ("Support fields that return top level operations"): #1200
The final implementation contains:

  • generating models without fields for root types (Query, Mutation etc) (plugin/modelgen/models.go)
  • skip generating resolver for field with root type and always return empty struct (codegen/field.go, codegen/field.gotpl)
  • fixes for templates to pass necessary number params to generated methods (codegen/type.gotpl that depends on codegen/config.TypeReference's Root field, that added in codegen/config/binder.go)

Also there are small improvements like adding IsRootDefinition method to Config to not to repeat def == c.Schema.Query || def == c.Schema.Mutation || def == c.Schema.Subscription everywhere

Who can review and merge it?

Build fails because generator on CI for some reason creates oneline methods instead of multiline:

-func (r *Resolver) BackedByInterface() BackedByInterfaceResolver {
-    return &backedByInterfaceResolver{r}
-}
+func (r *Resolver) BackedByInterface() BackedByInterfaceResolver { return &backedByInterfaceResolver{r} }

etc

Hey folks, my team’s use-case requires creating and destroying connections/pool at the resolver-level. We want to destroy these connections when a parent and its children are done. Is there any way to know, for a particular parent, when its child resolvers have finished executing?

Thanks,
Akhil

Has anyone got gqlgen run within a bazel project?

It fails with "merging failed: unable to find type github.com/99designs/gqlgen/graphql.Boolean". vendor directory does have these types. I guess I am not able to tell gqlgen (or go) to look for the types in vendor directory.

any example Unmarshal & Marshal primitive.ObjectID for MongoDB for model ? I want make scalar ObjectID to primitive.ObjectID
Muhammad
@harmnot

I was put this

  ObjectID:
    model:
      - go.mongodb.org/mongo-driver/bson/primitive.ObjectID

it was created on my model_gen.go
I got error validates like this : validation failed: packages.Load: .../resolver/generated.go ec.unmarshalInputObjectID undefined (type *executionContext has no field or method unmarshalInputObjectID)

I am afraid when into production this will make issue on my app ,
any idea?

Muhammad
@harmnot
trying again like this:
func MarshalObjectID(v primitive.ObjectID) graphql.Marshaler {
    return graphql.WriterFunc(func(w io.Writer) {
        err := json.NewEncoder(w).Encode(v)
        if err != nil {
            panic(err)
        }
    })
}

func UnmarshalObjectID(v primitive.ObjectID) (primitive.ObjectID, error) {
    return v, nil
}
got
cannot use v (variable of type interface{}) as primitive.ObjectID value in argument to model.UnmarshalObjectID

Hi everyone! Is there a way to define a naming schema for resolver files? Such as resolver/schema.go instead of schema.resolvers.go

+1 for the ability to override the name for resolvers. Not sure if gqlgen supports it.

hey, trying to get started w/ gqlgen (edit: sorry, cat hit enter)

we have a monorepo, and I want to have the gqlgen "root" be a subdirectory of the overall repo. is that possible?

I'm getting an error like module gitlab.com/mycompany/monorepo@latest found, but does not contain package gitlab.com/mycompany/monorepo/go/path/to/gqlgenroot/graph/model

maybe a related clarifying question... in a setup where the gqlgen "root" is not the repo root, a) where should gqlgen.yml go, b) where should the paths in gqlgen.yml be relative to?

While migrating from v0.10.2 to v0.11.3, generated.go doesn't compile:

/private/var/tmp/_bazel_sateesh/.../sandbox/darwin-sandbox/1531/execroot/__main__/bazel-out/darwin-fastbuild/bin/src/.../generated.go:4521:20: undefined: gqlparser

generated.go does not import gqlparser github.com/vektah/gqlparser/v2. However, it is used as var parsedSchema = gqlparser.MustLoadSchema(sources...)

How did the gqlparser import vanish from generated.go file?
