Question

我在控制器中得到了这个

var tobi = (from a in db.Assessments
join u in db.Users on a.rated equals u.user_id
join tm in db.Team_Members on u.user_id equals tm.user_id
join t in db.Teams on tm.team_id equals t.team_id
where (tm.end_date == null || tm.end_date > DateTime.Today)
group new TobiViewModel
{
    teamname = t.name,
    assessed_due = a.assessed_due,
    assessment_id = a.assessment_id,
    rater = a.rater,
    rated = a.rated
}
by new { t.name, a.rated }).ToList();

return View(tobi);

但是它在视图中不接受它？

传递到字典中的模型项是类型的 'System.Collections.Generic.List 1[System.Linq.IGrouping 2 [＆LT;＆GT; f__AnonymousType10 2[System.String,System.String],Kyubu.ViewModels.TobiViewModel]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable 1 [Kyubu.ViewModels.TobiViewModel]'。

我应该如何在视图中传递此信息。任何帮助，将不胜感激视图中的类型是

@model IEnumerable<Kyubu.ViewModels.TobiViewModel>

Answer 1

在视图中尝试以下内容：

@model IEnumerable<System.Linq.IGrouping<object, Kyubu.ViewModels.TobiViewModel>>

使用group by传递linq查询以查看[错误输出]
