Issue while running `go run convert_plugin.go`

[alichherawalla]

Thanks for this amazing library!

Currently when executing go run convert_plugin.go I'm getting the following error

panic: recursive or concurrent call to RenderToFile detected

my gqlgen.yml looks like this

schema:
  - schema.graphql
exec:
  filename: graphql/generated.go
  package: graphql
model:
  filename: graphql/models/generated_models.go
  package: gqlmodels
resolver:
  filename: graphql/resolver.go
  type: Resolver

any idea why this would be an issue?

[RichardLindhout]

Does this work

gqlgen.yml

schema:
  - ../schema.graphql
exec:
  filename: graphql_models/generated.go
  package: graphql_models
model:
  filename: graphql_models/generated_models.go
  package: graphql_models
resolver:
  filename: resolver.go
  type: Resolver

[RichardLindhout]

The directories needs aliasing so these are required till a next release| graphql_models for gqlgen models models for sqlboiler models

[RichardLindhout]

Do you have single or multiple schema.graphql?

[alichherawalla]

Hi, thanks for the swift response.

It doesn't work with the gqlgen.yml you posted, unfortunately.

I have a single schema.graphql

[alichherawalla]

this is the full stack trace

[alichherawalla]

also btw i'm using postgres

[RichardLindhout]

Hmm strange, on what versions are you of gqlgen and sqlboiler? I'm on the latest versions of both.

[RichardLindhout]

• what is the content of your convert_plugin.go

Mine is:

// +build ignore

package main

import (
    "fmt"
    "os"

    "github.com/99designs/gqlgen/api"
    "github.com/99designs/gqlgen/codegen/config"
    convertsGenerator "github.com/web-ridge/gqlgen-sqlboiler/convert"
    resolverGenerator "github.com/web-ridge/gqlgen-sqlboiler/resolver"
)

func main() {
    cfg, err := config.LoadConfigFromDefaultLocations()
    if err != nil {
        fmt.Fprintln(os.Stderr, "failed to load config", err.Error())
        os.Exit(2)
    }

    convertHelpersDir := "helpers"
    sqlboilerDir := "models"
    gqlgenModelDir := "graphql_models"

    err = api.Generate(cfg,
        api.AddPlugin(convertsGenerator.New(
            convertHelpersDir, // directory where convert.go, convert_input.go and preload.go should live
            sqlboilerDir,      // directory where sqlboiler files are put
            gqlgenModelDir,    // directory where gqlgen models live
        )),
        api.AddPlugin(resolverGenerator.New(
            convertHelpersDir,
            sqlboilerDir,
            gqlgenModelDir,
            "gitlab.com/decicify/app/backend/auth",
        )),
    )
    if err != nil {
        fmt.Println("error!!")
        fmt.Fprintln(os.Stderr, err.Error())
        os.Exit(3)
    }
}

[RichardLindhout]

It crashes on this line in qqlgen code. https://github.com/99designs/gqlgen/blob/master/codegen/templates/templates.go#L68

Your convert_plugin.go file needs to live in the same folder as the project where you want to generate.

[RichardLindhout]

Did you generate your models for your database with https://github.com/volatiletech/sqlboiler?

[alichherawalla]

I'm on the latest versions of gqlgen and sqlboiler as well. yes i've generated the database models from sqlboiler. and yes the convert_plugin is in the root folder

[RichardLindhout]

Interesting, to be honest I don't know if the output of sqlboiler is any different than with postgressql vs mysql.

What operating system do you use?

[alichherawalla]

macos

[RichardLindhout]

Me too :)

[alichherawalla]

i simplified the schema to have a just single type with a few scalar fields but it still doesn't work for some reason

[RichardLindhout]

Can you share your schema (maybe privately)

[RichardLindhout]

My email is on my profile

[RichardLindhout]

I'm generating my schema with: https://github.com/web-ridge/sqlboiler-graphql-schema a.t.m.

go run github.com/web-ridge/sqlboiler-graphql-schema --output=../schema.graphql --skip-input-fields=organizationId --directives=isAuthenticated

[RichardLindhout]

Maybe I made some assumptions about the schema.grapql which are not always true for everyone.

[alichherawalla]

I used that to generate my schema as well

[alichherawalla]

I tried it on a playground Blog/Comment/Post project as well, let me share that schema with you

[RichardLindhout]

I did have this issue too now I remember: the cause is here. https://github.com/99designs/gqlgen/blob/master/codegen/templates/templates.go#L62

This library generates multiple files instead of one, so we we needed to prevent this panic from happening.

That was fixed 6 days ago: https://github.com/web-ridge/gqlgen-sqlboiler/blob/master/convert/convert.go#L208

Somehow go.mod does not always understand how to update to the latest version

Maybe put this instead of the other web-ridge vendors in go.mod and run go mod tidy. And try regenerating.

[alichherawalla]

that doesn't seem to work, could you please send me your go.mod?

[RichardLindhout]

I've added an example. https://github.com/web-ridge/gqlgen-sqlboiler/tree/master/examples/social-network

I do something wrong here with go-modules maybe I need to split up the project or something like that to keep everything on latest version

[alichherawalla]

what's the go version that you are on?

[alichherawalla]

i've added the project locally to make sure that there are no issues with the version for now but it still doesn't seem to work. I wasn't able to run your project either. Could it be something in the environment configuration?

[RichardLindhout]

➜ ~ go version go version go1.13.5 darwin/amd64

[RichardLindhout]

I don't know, it's strange!

[RichardLindhout]

I also don't have problems with latest version of golang go version go version go1.14.2 darwin/amd64

[RichardLindhout]

Ah!! I have the same problem now if I take it outside my golang path src directory

[RichardLindhout]

[RichardLindhout]

I think I need to rewrite this function or something like that. https://github.com/web-ridge/gqlgen-sqlboiler/blob/master/convert/convert.go#L134

Do you have the option available to move to your GOPATH folder?

[alichherawalla]

that did the trick! Thanks very much

[RichardLindhout]

In v2.1.1 it works outside of GOPATH!

@randallmlough added support for repositories outside of GOPATH based on where the go.mod file lives👌
