[英]The current request for action 'AdminManagement' on controller type 'AdminController' is ambiguous between the following action methods
[英]The current request for action […] on controller type '…' is ambiguous between the following action methods
我无法解决此问题。
在以下操作方法之间,当前对控制器类型“ ProductController”的操作“ ListProducts”的请求是模棱两可的:类型为Nettbutikk.Controllers.ProductController的System.Web.Mvc.ActionResult ListProducts(System.Nullable`1 [System.Int32]) Nettbutikk.Controllers.ProductController类型的.Web.Mvc.ActionResult ListProducts(Int32,System.String)
有人可以帮助我吗?
内容:
public List<Product> getAll(int id, string something)
{
var db = new DatabaseContext();
List<Product> allProducts = new List<Product>();
var products = db.Products.Where(p => p.SubCategoriesId == id).ToList();
foreach (var p in products)
{
var product = new Product()
{
itemnumber = p.Id,
name = p.Name,
description = p.Description,
price = p.Price,
volum = p.Volum,
producer = p.Producers.Name,
pricePerLitre = pricePerLitre(p.Price, p.Volum),
category = p.SubCategories.Categories.Name,
subCategory = p.SubCategories.Name,
country = p.Countries.Name
};
allProducts.Add(product);
}
return allProducts;
}
控制器:
public ActionResult ListProducts(int? id)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id);
return View(listOfProducts);
}
public ActionResult ListProducts(int id, string something)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id,tull);
return View(listOfProducts);
}
和视图:
<a href='@Url.Action("ListProducts", "Product", new { id = 1, tull = "" })'>sub category</a>
这是因为您有两个重载的操作,这些操作导致路由混乱。 在您的示例中,您认为
<a href='@Url.Action("ListProducts", "Product", new { id = 1, tull = "" })'>sub category</a>
将转到ListProducts(int id,字符串的东西)。 没有! 这是错误的假设。...URL类似于yourdomain / 1,因为某些内容为空。...这似乎是第一个动作。
因此,当某个变量为空时,这两种操作方法会使路由引擎感到困惑。
因此,将名称更改为其他名称
public ActionResult ListProductsbyId(int? id)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id);
return View(listOfProducts);
}
public ActionResult ListProductsByIdAndTull (int id, string tull)
{
var db = new DBProduct();
List<Product> listOfProducts;
listOfProducts = db.getAll(id,tull);
return View(listOfProducts);
}
或只是一个动作
public ActionResult ListProducts(int? id, string tull)
{
var db = new DBProduct();
List<Product> listOfProducts;
if(String.IsNullOrEmpty(tull)
{
listOfProducts = db.getAll(id);
}
else
{
listOfProducts = db.getAll(id,tull);
}
return View(listOfProducts);
}
