Get data from two tables(join) with linq and return result into view
I have two tables: Projects and ProjectsData and I want to execute query with join and get the result in the View.
In the Controller I have this code:
ViewBag.projectsData = (from pd in db.ProjectsData
join p in db.Projects on pd.ProjectId equals p.ID
where pd.UserName == this.HttpContext.User.Identity.Name
orderby p.Name, p.ProjectNo
select new { ProjectDat开发者_如何学JAVAa = pd, Project = p });
What I should use in the View to extract this data. I tried that:
@foreach (var item in ViewBag.projectsData)
{
@item.pd.UserName
}
but it doesn't work...
In your view you are trying to access a pd
property but such property doesn't exist. The property is called ProjectData
.
This being said I would strongly recommend you to use view models and strongly typed views instead of ViewBag
. This way you will also get Intellisense in your view which would have helped you pick the correct names.
So you could start by defining a view model that will hold all the information your view would need:
public class MyViewModel
{
public ProjectData ProjectData { get; set; }
public Project Project { get; set; }
}
and then inside your controller action populate this view model and pass to the view:
public ActionResult Index()
{
var viewModel =
from pd in db.ProjectsData
join p in db.Projects on pd.ProjectId equals p.ID
where pd.UserName == this.HttpContext.User.Identity.Name
orderby p.Name, p.ProjectNo
select new MyViewModel { ProjectData = pd, Project = p };
return View(viewModel);
}
and finally inside your strongly typed view use the view model:
@model IEnumerable<AppName.Models.MyViewModel>
@foreach (var item in Model)
{
<div>@item.ProjectData.UserName</div>
}
