在我的应用程序中,我有一个项目登记册。要访问这些项目是 url:/project/{url-project}
the value of `{url-project}` is defined in the registration of the project!
我使用这个项目来生成路径,但由于“注册项目”是动态的,因此必须手动实现它,如本文所示。
所以我做了:
public class ProjectDetailsDynamicNodeProvider : DynamicNodeProviderBase
{
[Inject]
public IProjectRepository ProjectRepository { get; set; }
#region Overrides of DynamicNodeProviderBase
public override IEnumerable<DynamicNode> GetDynamicNodeCollection()
{
// Build value
var returnValue = new List<DynamicNode>();
var listDB = (from p in ProjectRepository.Query()
select new { p.Name, p.ID });
// Create a node for each album
foreach (var project in listDB.ToList())
{
var node = new DynamicNode { Title = project.Name };
node.RouteValues.Add("id", project.ID);
returnValue.Add(node);
}
// Return
return returnValue;
}
#endregion
}
在我的 Mvc.sitemap
<mvcSiteMapNode title="Projetos" controller="Project" action="Index">
<mvcSiteMapNode title="Novo Projeto" controller="Project" action="Create" />
<mvcSiteMapNode title="Projeto" action="About" dynamicNodeProvider="BindSolution.Infra.ProjectDetailsDynamicNodeProvider, BindSolution" />
</mvcSiteMapNode>
问题
我的问题是ProjectRepository
始终为空!
kernel.Bind<IProjectRepository>().To<ProjectRepository>().InRequestScope();
但在我的设置中,Ninject 是正确的!该存储库在控制器中使用,并且运行良好!
尝试
我试图通过构造函数注入这个依赖,但结果是一样的!
public class ProjectDetailsDynamicNodeProvider : DynamicNodeProviderBase
{
public IProjectRepository ProjectRepository { get; set; }
public ProjectDetailsDynamicNodeProvider(IProjectRepository projectRepository)
{
ProjectRepository = projectRepository
}
#region Overrides of DynamicNodeProviderBase
public override IEnumerable<DynamicNode> GetDynamicNodeCollection()
{
// Build value
var returnValue = new List<DynamicNode>();
var listDB = (from p in ProjectRepository.Query()
select new { p.Name, p.ID });
// Create a node for each album
foreach (var project in listDB.ToList())
{
var node = new DynamicNode { Title = project.Name };
node.RouteValues.Add("id", project.ID);
returnValue.Add(node);
}
// Return
return returnValue;
}
#endregion
}
