表1 hasMany in Table 2仅包括最后一行

Question

我有2张桌子。首先是“文档”，它与第二个具有“ hasMany”关系的表2“ DocumentVersions”相关。我正在尝试获取文档并将表2中的最后一行包含在表1中的公共虚拟DocumentVersion属性中。

在我的存储库中，这就是我尝试获取的方式

return _dcmsContext.Documents
                    .Include(d => d.DocumentCategory)
                    .Include(d => d.Project)
                    .Include(d => d.Department)
                    .Include(d => d.Author)
                    .Include(d => (d.DocumentVersions.LastOrDefault()))
                    .Where(d => 
                        d.IsActive == isActive && 
                        projectIds.Contains(d.ProjectId) &&
                        (d.RestrictByDepartment == false || d.DepartmentId == user.DepartmentId) &&
                        (d.RestrictByLocation == false || d.ProjectId == user.ProjectId));

上下文：

modelBuilder.Entity<Document>(entity =>
            {
                entity.HasMany(d => d.DocumentVersions);
                entity.HasOne(d => d.DocumentCategory);
                entity.HasOne(d => d.Department);
                entity.HasOne(d => d.Project);
                entity.HasOne(d => d.Author);
                entity.HasOne(d => d.LastestVersion);
            });

文档类（表1）：

        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int DocumentId { get; set; }
        [NotMapped]
        public virtual DocumentVersion LastestVersion { get; set; }

DocumentVersions类（表2）：

        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int DocumentVersionId { get; set; }

        [ForeignKey("Document")]
        public int DocumentId { get; set; }
        [Required]
        public float Version { get; set; }

我还尝试了多种方法来实现此目的，如下面的代码，但没有运气。

.Include(d => (d.DocumentVersions.LastOrDefault() as d.LatestVersion))

我正在尝试像这样：

[
    {
        "documentId": 1,
        "title": "Sample",
        "description": "test",
        "restrictByDepartment": false,
        "latestVersion": {
            "documentId": 3,
            "documentVersionId": 8,
            "version": 5
        }
]
