GORM Repository

Gormrepo is a repository generator for Gorm.

Install

$ go get github.com/l-vitaly/gormrepo/cmd/gormrepogen/...

For example, given this struct:

package model

type User struct {
    gorm.Model
    FirstName string
    LastName string
    Birthday time.Time
}

running this command:

$ gormrepogen -t=User

in the same directory will create the file user_base_repo.go, in package model and struct userBaseRepo.

Typically this process would be run using go generate, like this:

//go:generate gormrepogen -t=User

Example

package main

import (
	"github.com/jinzhu/gorm"
	"github.com/l-vitaly/gormrepo"
)

type UserRepo struct {
    userBaseRepo
}

func NewUserRepo(db *gorm.DB) *UserRepo {
    return &UserRepo{userBaseRepo{Repo: db}}
}

func main() {
    db, err := gorm.Open("postgres", "postgres://localhost:5432/dbname")
	if err != nil {
		log.Println("err", err)
		os.Exit(1)
	}
	defer db.Close()
	
	userRepo := NewUserRepo(db)
	
	// use repo here
}
