ASP.NET MVC。 如何在视图页面中显示测试而不是 id？

Question

I have a view (Index) which display data from a model (TBL_PROJECT).

@foreach (var item in Model)
{
    <tr>
        <td>
            @Html.DisplayFor(m => item.PROJ_YEAR)
        </td>
        <td>
            @Html.DisplayFor(m => item.PROJ_NAME)
        </td>
        <td>
            @Html.DisplayFor(m => item.PROJ_STATUS)
        </td>
    </tr>
}

When displayed it would be:
1998 Paint 1
1998 Cleaning 1

I need the status to be in text, which is in another model(TBL_STATUS).
What should I do?
This is the TBL_STATUS Model

public class TBL_STATUS
{
    public int ID { get; set; }
    public string STATUS { get; set; }
}

This is the controller

public ActionResult Index(int page = 1, string Query = null)
{
    var projectList = db.TBL_PROJECTS.Include(x => x.TBL_STATUS).Where(x => x.PROJ_CAT == 1).ToList().OrderByDescending(x => x.ID);

    if (!string.IsNullOrEmpty(Query))
    {
        projectList = projectList
            .Where(x => x.PROJ_NAME.ToLower().Contains(Query.ToLower()))
            .ToList().OrderByDescending(x => x.ID);
    }
    return View(new PagedList.PagedList<TBL_PROJECT>(projectList, page, 10));
}

Update: I found out a way the way to do it. In the model (TBL_PROJECT) I add this:

    [Display(Name = "Current Status")]
    public int PROJ_STATUS { get; set; }

    [ForeignKey("PROJ_STATUS")]
    public TBL_STATUS TBL_STATUS { get; set; }

and when calling it in the View:...

 <td>
    @Html.DisplayFor(m => item.TBL_STATUS.STATUS)
 </td>

Now I have another issue. Same issue, I want to add a district (which is an int in the TBL_PROJECT which refer to another model (TBL_DISTRICT)).

    public class TBL_DISTRICT
{
    public int ID { get; set; }
    public string DIST_NAME { get; set; }
    public string DIST_OFFICE { get; set; }
    public string DIST_CODE { get; set; }
}

Now, in my TBL_PROJECT model, I add these:

    [Display(Name = "District")]
    public int DISTRICT { get; set; }

    [ForeignKey("DISTRICT")]
    public TBL_DISTRICT TBL_DISTRICT { get; set; }

And in the view:

@Html.DisplayFor(m => item.TBL_DISTRICT.DIST_NAME )

Theres no error but it returned nothing. Do I need to add constraint between these tables (TBL_PROJECT & TBL_DISTRICT)?

Answer 1

Add the following line in TBL_PROJECT Model.

public class TBL_PROJECT
{
//Code you have
public virtual TBL_STATUS TBL { get; set; }
}

Then modify the view

@foreach (var item in Model)
        {
                <tr>
                    <td>
                        @Html.DisplayFor(m => item.PROJ_YEAR.STATUS)
                    </td>
                    <td>
                        @Html.DisplayFor(m => item.PROJ_NAME)
                    </td>
                    <td>
                        @Html.DisplayFor(m => item.TBL.STATUS)
                    </td>
                </tr>
            }

Answer 2

Try to use foreign key reference.

Answer 3

Found the answer. I put this first line in the controller.

var projectList = db.TBL_PROJECTS.Include(x => x.TBL_STATUS).Include(x => x.TBL_DISTRICT).Where(x => x.PROJ_CAT == 1).ToList().OrderByDescending(x => x.ID);

I just add another Include(x => x.TableName)

Answer 4

使用@Html.Display(item.PROJ_STATUS.ToString())
