Gorm和关系

Question

我对Golang是新手，对Gorm更是如此。我正在尝试建立一对多的关系。基本上只有一个报价器符号和他的许多报价器数据。一切都很好，除了我不能让模型上的关系继续运行。我只需要一点关于如何做到这一点的提示(欢迎最佳实践)。

main.go

package main

import (
    "github.com/jinzhu/gorm"
    "github.com/khwerhahn/quoteworker/common"
    "github.com/khwerhahn/quoteworker/tickerdata"
    "github.com/khwerhahn/quoteworker/ticker"
)

// Migrate database
func Migrate(db *gorm.DB) {
    ticker.AutoMigrate()
    tickerdata.AutoMigrate()
}

func main() {
    db := common.Init()
    Migrate(db)
    defer db.Close()
    //// more code....
}

存在于它自己的文件和包中。自动收报机的model.go

package ticker

import (
    "github.com/jinzhu/gorm"
    "github.com/khwerhahn/quoteworker/common"
)

type TickerModel struct {
    gorm.Model
    Name   string `gorm:"column:name;unique_index"`
    Symbol string `gorm:"column:symbol;unique_index"`
}

// AutoMigrate the schema of database if needed
func AutoMigrate() {
    db := common.GetDB()
    db.AutoMigrate(&TickerModel{})
}

存在于它自己的文件和包中。tickerdata的model.go

package tickerdata

import (
    "github.com/jinzhu/gorm"
    "github.com/khwerhahn/quoteworker/common"
    "github.com/khwerhahn/quoteworker/ticker"
)

type TickerDataModel struct {
    gorm.Model
    Rank                           int     `gorm:"column:rank"`
    // left out some stuff....
    TickerModel                     ticker.TickerModel
    TickerModelID                   uint `gorm:"column:tickerId"`
}

// AutoMigrate the schema of database if needed
func AutoMigrate() {
    db := common.GetDB()
    db.AutoMigrate(&TickerDataModel{})
}

Thx
