Insertion order of multiple records in Entity Framework

Question

I\'m having trouble with EF reordering my inserts when I try and add an entity with multiple children all at once. I\'ve got a 3 level structure with one-to-many relationsh

Answer 1

It's not professional. But, I solved my problem with this method.

PublicMenu.cs file:

public class PublicMenu
    {
        public int Id { get; set; }

        public int? Order { get; set; }
        
        public int? ParentMenuId { get; set; }

        [ForeignKey("ParentMenuId")]
        public virtual PublicMenu Parent { get; set; }

        public virtual ICollection Children { get; set; }

        public string Controller { get; set; }

        public string Action { get; set; }

        public string PictureUrl { get; set; }

        public bool Enabled { get; set; }
}

PublicMenus.json file

[
    {
        "Order": 1,
        "Controller": "Home",
        "Action": "Index",
        "PictureUrl": "",
        "Enabled": true
    },
    {
        "Order": 2,
        "Controller": "Home",
        "Action": "Services",
        "PictureUrl": "",
        "Enabled": true
    },
    {
        "Order": 3,
        "Controller": "Home",
        "Action": "Portfolio",
        "PictureUrl": "",
        "Enabled": true
    },
    {
        "Order": 4,
        "Controller": "Home",
        "Action": "About",
        "PictureUrl": "",
        "Enabled": true
    },
    {
        "Order": 5,
        "Controller": "Home",
        "Action": "Contact",
        "PictureUrl": "",
        "Enabled": true
    }
]

DataContextSeed file

    public class DataContextSeed
        {
            public static async Task SeedAsync(ICMSContext context, ILoggerFactory loggerFactory)
            {
                try
                {
                       if (!context.PublicMenus.Any())
                        {
                            var publicMenusData = File.ReadAllText("../Infrastructure/Data/SeedData/PublicMenus.json");
                            var publicMenus = JsonSerializer.Deserialize>(publicMenusData);
                            foreach (var item in publicMenus)
                            {
                                context.PublicMenus.Add(item);
                                await context.SaveChangesAsync();
                            }
                       }
                }
                catch (Exception ex)
                {
                    var logger = loggerFactory.CreateLogger();
                    logger.LogError(ex.Message);
                }
            }
   }
