[SugarTable("STudent")]

public class Student

{

[SugarColumn(IsPrimaryKey = true, IsIdentity = true, ColumnName = "ID")]

public int Id { get; set; }

public int? SchoolId { get; set; }

public string Name { get; set; }

public DateTime? CreateTime { get; set; }

[SugarColumn(IsIgnore=true)]

public int TestId { get; set; }

public School School { get; set; }

}

var db = GetInstance();

var q = db

.Queryable<Student>()

.Where(a => a.Name == "1");

q = q.Where(b => b.Name == "2");

q = q.Where(c => c.School.Name == "3");

var r = q.ToList();

然后就报错了，如图：

如果支持导航属性的查询（EF是支持这种写法的），麻烦给个文档示例，非常感谢。
