使用RazorPDF错误转换视图

Question

I build this format of link: http://localhost:33333/Invoices/Reports?format=pdf 我建立了这种链接格式： http：// localhost：33333 / Invoices / Reports？format = pdf

When I run this shows this error: 当我运行这显示此错误：

System.InvalidOperationException: The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery 1[<>f__AnonymousType9 11[Webb.Models.Faktury,System.Int32,System.String,System.Nullable 1[System.DateTime],System.Nullable 1[System.DateTime],System.Nullable 1[System.Single],System.Nullable 1[System.Int32],System.String,System.Nullable 1[System.Single],System.Nullable 1[System.Single],System.Nullable 1[System.Single]]]', but this dictionary requires a model item of type 'System.Collections.Generic.List 1[Webb.Models.Faktury]'.

Controller: 控制器：

// Setup sample model
            var pro = (from a in db.Fakturies
                       join b in db.Wierszes on a.FAK_Id equals b.WIE_Fkid
                       join c in db.Produkties on b.WIE_Pid equals c.PRO_Id

                       select new
                       {
                           a,
                           a.FAK_Id,
                           a.FAK_Numer,
                           a.FAK_DataS,
                           a.FAK_TerminZ,
                           a.FAK_Rabat,
                           b.WIE_Ilosc,
                           c.PRO_Nazwa,
                           c.PRO_CenaN,
                           c.PRO_CenaB,
                           c.PRO_Vat
                       });


            pro = pro.Where(a => a.FAK_Id == 6);

            // Output to Pdf?
            if (Request.QueryString["format"] == "pdf")
                return new PdfResult(pro, "Reports");

            return View(pro);
        }

What should I do to export success view to pdf with data from database? 我应该如何使用数据库中的数据将成功视图导出为pdf？

            var vm = new PrintViewModel();
            vm.Fakturies = pro;  //assuming pro is already loaded with the above code.
            vm.Wierszes = db.Wierszes;


            if (Request.QueryString["format"] == "pdf")
                return new PdfResult(vm, "Reports");

            return View(vm);

Your view is strongly typed to a collection of Faktury . 您的观点与Faktury的集合Faktury 。 But from your action method you are passing a collection of annonymous objects. 但是从您的操作方法中，您正在传递匿名对象的集合。

Change your LINQ expression code to do a projection using the Faktury class. 更改LINQ表达式代码以使用Faktury类进行投影。

var pro = (from a in db.Fakturies
                   join b in db.Wierszes on a.FAK_Id equals b.WIE_Fkid
                   join c in db.Produkties on b.WIE_Pid equals c.PRO_Id
                   select a);

pro = pro.Where(a => a.FAK_Id == 6);

 if (Request.QueryString["format"] == "pdf")
      return new PdfResult(pro.ToList(), "Reports");

return View(pro);

If you need to pass more information than the list of Fakturties, you may create a view model with the properties you need. 如果您需要传递比Fakturties列表更多的信息，则可以使用所需的属性创建视图模型。

public class PrintViewModel
{
  public IEnumerable<Faktury> Fakturies {set;get;}
  public IEnumerable<Wiersz> Wierszes {set;get;}  

  public PrintViewModel()
  {
    this.Fakturies = new List<Faktury>();
    this.Wierszes = new List<Wiersz>();
  }
}

and in your action method, create an object of this, assign the property values and send to the view. 然后在您的操作方法中，创建一个对象，分配属性值并将其发送到视图。

var vm=new PrintViewModel();
vm.Fakturies=pro;  //assuming pro is already loaded with the above code.
vm.Wierszes =db.Wierszes;
return View(vm);

Now make sure that your view is strongly typed to this new view model 现在，请确保您的视图已严格键入此新视图模型

@model PrintViewModel
<h3>Fatturies</h3>
@foreach(var f in Model.Fakturies)
{ 
  <p>@f.FAK_Numer</p>
}
<h3>Wierszes</h3>
@foreach(var f in Model.Wierszes)
{ 
  <p>@f.Name</p>
}
