Question

我遇到了这个错误：

The model item passed into the dictionary is of type 
'Nop.Web.Models.Catalog.SearchModel', but this dictionary requires a model 
item of type 'Nop.Web.Models.Catalog.CategoryModel'

完整的错误是这样的：

is of type 'Nop.Web.Models.Catalog.SearchModel', but this dictionary requires 
a model item of type 'Nop.Web.Models.Catalog.CategoryModel'. at

我修改了 SearchBox.cshtml 以插入我需要父类别 (cid) 和搜索文本 (q) 的输入。所以为了找到我从服务器 SearchBox.cshtml 和 Search.cshtml 删除的错误，但它给了我同样的错误。

我使用的是 nopCommerce 3.90 版

谁能帮我解决这个错误。

Answer 1

您将模型传递给控制器查看 - Nop.Web.Models.Catalog.SearchModel 并在视图页面中使用模型 - Nop.Web.Models.Catalog.CategoryModel

在视图页面中使用模型 Nop.Web.Models.Catalog.SearchModel，它将解决您的问题。
