Go 1.12 modules: local import in non-local import

I'm currently using Go 1.12 modules and really tired about importing.

I'm making the rest-api using gin(web microservices) and gorm(golang orm). Everything still ok while working in golang modules. But getting trouble with local packages importing

The directory tree:

project tree

The go.mod:

module github.com/Aragami1408/go-gorm

go 1.12

require (
    github.com/gin-gonic/gin v1.4.0
    github.com/jinzhu/gorm v1.9.9
    github.com/lib/pq v1.1.1
    github.com/satori/go.uuid v1.2.0
)

The db.go: 

package db

//code below...

The tasks.go: 

package task

import (
    "../db"
)

But when I run and still get this error:

local import "../db" in non-local package

I've searched a lot on google and nothing helps

When migrating to go as "package manager", you may create the file go mod using the command :

go mod init myhost/myrepo/mymodule

Then the file will be created go.mod will be created :

module myhost/myrepo/mymodule

go 1.15

Now you can leverage this file to list your dependencies to other modules :

# i.e: your module mymodule depends on github.com/gorilla/mux
go get github.com/gorilla/mux

You run it? then check again the content of go.mod

module myhost/myrepo/mymodule

go 1.15

require (
    github.com/gorilla/mux v1.7.4
)

You are happy because you leverage the package manager features and you are managing dependencies like a Boss.

However,...

However, you forget that you need to maintain all go files which imports directories with relative paths.

example :

if you have main.go

package main

import (
    "fmt"

    "./router" // !! RELATIVE PATH
)

You must migrate also by replacing the relative path with [module-name]/relative-path. in this case, it must become :

package main

import (
    "fmt"

    "myhost/myrepo/mymodule/router" // !! 💼 No more RELATIVE PATH
)

If you are using go modules you can replace your package by a local one using:

go mod edit -replace github.com/username/project=/localpath

then just call

go get github.com/username/project

and everything should work fine.

From "Do modules work with relative imports like import "./subdir"?"

In modules, there finally is a name for the subdirectory.

If the parent directory says "module m" then the subdirectory is imported as "m/subdir", no longer "./subdir".

In your case:

import "github.com/Aragami1408/go-gorm/db"
# or maybe
import "go-gorm/db"

This assumes, as commented below by Silvio Lucas, that you have set GO111MODULE=on.
