无法从 gqlgen-sqlboiler 生成 generated_sort.go

php小编新一提到，有时候在使用gqlgen-sqlboiler生成器时，可能会遇到无法生成generated_sort.go文件的问题。这个问题可能是由于配置或者依赖关系的错误导致的。在解决这个问题之前，我们需要仔细检查配置文件和相关依赖，确保没有遗漏或者错误。同时，我们也可以尝试更新生成器和相关库的版本，以解决可能存在的bug。如果问题仍然存在，我们可以寻求社区的帮助，看看是否有其他人遇到了相同的问题，并且找到了解决办法。总之，解决这个问题需要耐心和细心，通过排查和尝试不同的解决方案，我们有望找到有效的解决方法。

问题内容

我正在使用 sqlboiler版本：v4.14.2 gqlgen版本：v0.17.33 gqlgen-sqlboiler 版本：v3.3.12 https://github.com/web-ridge/gqlgen-sqlboiler

遵循 readme.md 先决条件后，在运行 convert.go 时出现以下错误 以下是convert.go

请帮忙解决这个问题？

解决方法

通过映射正确的目录解决了问题。在侧面convert.go 在convert.go中创建结构时

//output 代表将从 gqlgen-sqlboiler 生成文件的文件夹

output := structs.config{
        directory:   "helpers", // supports root or sub directories
        packagename: "helpers",
    }

//backend是生成所有sqlboiler模型的文件夹

backend := structs.config{
    directory:   "models",
    packagename: "models",
}

//！！！重要的前端是gqlgen生成所有graphql文件的文件夹

frontend := structs.Config{
    Directory:   "graph",
    PackageName: "graph",
}

前端文件夹映射错误。

以上是无法从 gqlgen-sqlboiler 生成 generated_sort.go的详细内容。更多信息请关注PHP中文网其他相关文章！
