[Question] How create related entities objts in one form?

[Todvaa]

Description

Greetings! I have two related entities whose attributes I display together. Is there a way to create them together in a form? Or make two forms for creating these entities in a row. Thank You!!!

Example code

package models

import (
	"gorm.io/gorm"
)

type Article struct {
	gorm.Model // adds ID, created_at etc.

	SitePosition int `json:"site_position" gorm:"uniqueIndex:page_site_position_uniq"`

	PageName string `json:"page_id" gorm:"type:varchar(25);not null;uniqueIndex:page_site_position_uniq"`
	Page     Page   `json:"page" gorm:"foreignKey:PageName;references:Name"`
}

type ArticleTranslation struct {
	gorm.Model // adds ID, created_at etc.

	Text string `json:"text" gorm:"type:text"`

	LocalizationName string       `json:"localization_name" gorm:"type:char(2);not null;uniqueIndex:localization_article_uniq" validate:"required"`
	Localization     Localization `json:"-" gorm:"foreignKey:LocalizationName;references:Name"`
	ArticleID        uint         `json:"article_id" gorm:"uniqueIndex:localization_article_uniq"`
	Article          Article      `json:"-" gorm:"constraint:OnUpdate:CASCADE,OnDelete:CASCADE;"`
}

package tables

import "github.com/GoAdminGroup/go-admin/template/types"

const (
	ID             = "Номер"
	TranslationsID = "Номер перевода"
	Text           = "Текст"
	Localization   = "Язык"
	SitePosition   = "Позиция на сайте"
	Page           = "Страница размещения"
)
const (
	Articles     = "Тексты"
	ArticlesDesc = "Отдельные тексты на страницах"
)

var LocalizationOptions = types.FieldOptions{
	{Text: "Русский", Value: "ru"},
	{Text: "English", Value: "en"},
}

var PageOptions = types.FieldOptions{
	{Text: "Главная страница", Value: "main"},
	{Text: "Работа у нас", Value: "jobs"},
}

package tables

func GetArticlesTable(ctx *context.Context) table.Table {

	articles := table.NewDefaultTable(ctx, table.Config{
		Driver:     db.DriverPostgresql,
		CanAdd:     true,
		Editable:   true,
		Deletable:  true,
		Exportable: true,
		Connection: table.DefaultConnectionName,
		PrimaryKey: table.PrimaryKey{
			Type: db.Int,
			Name: "id",
		},
	})

	info := articles.GetInfo()

	info.SetTable("article_translations").SetTitle(Articles).SetDescription(ArticlesDesc)
	info.AddField(ID, "article_id", db.Int)
	info.AddField(Text, "text", db.Text)
	info.AddField(Localization, "localization_name", db.Text)
	info.AddField(SitePosition, "site_position", db.Int).FieldJoin(types.Join{
		Table:     "articles",
		Field:     "article_id",
		JoinField: "id",
	})
	info.AddField(Page, "page_name", db.Varchar).FieldJoin(types.Join{
		Table:     "articles",
		Field:     "article_id",
		JoinField: "id",
	})
	info.AddField(TranslationsID, "id", db.Int)

	formList := articles.GetForm()
	formList.SetTable("article_translations").SetTitle(Articles).SetDescription(ArticlesDesc)
	formList.AddField(ID, "article_id", db.Int, form.Default).FieldDisplayButCanNotEditWhenUpdate().FieldDisableWhenCreate()
	formList.AddField(Localization, "localization_name", db.Text, form.SelectSingle).
		FieldOptions(LocalizationOptions).FieldDisplayButCanNotEditWhenUpdate()
	formList.AddField(Text, "text", db.Text, form.Text)

	SitePosition ????

	Page ????

	return articles
}
