Getting data from umbraco inside a controller

API Questions

HI,

I managed to get get data from umbraco using hive inside a razor view, but I couldn't work out how to do it in a controller. Is that the only way do it? If so, it seems counter intuitive and not very testable. I would expect to be able to constuct a Hive object via injecting stufff into the constructor of my controller.

Anyone managed to do this?

Thanks,

Lee

I found this on the wiki: http://jupiter.umbraco.org/Data-Access-in-Umbraco-5.ashx?HL=hive

var mappingGroup = context.Hive.GetProviderMapForRoute("/news/archive/my-news-article"); // First get the providers for the current route

using (var unit = _mappingGroup.CreateReadOnlyUnitOfWork()) // Get a unit of work for the group

{

Assert.IsNotNull(unit.ReadRepository.GetEntityByRoute("/news/archive/my-news-article")); // Retrieve the entity by its route

}

How do I get the context object though?

Ah ha! Getting closer. If you are using a surface controller, you can do this:

public class WordSurfaceController : SurfaceController {

public ActionResult Index() {

var context = RoutableRequestContext.Application.Hive.Context;

var mappingGroup = context.Hive.GetProviderMapForRoute("/news/archive/my-news-article"); // First get the providers for the current route

using (var unit = _mappingGroup.CreateReadOnlyUnitOfWork()) // Get a unit of work for the group

{

Assert.IsNotNull(unit.ReadRepository.GetEntityByRoute("/news/archive/my-news-article")); // Retrieve the entity by its route

}

return PartialView(); } }

BOOM

using System;

using System.Collections.Generic;

using System.Web.Mvc;

using Umbraco.Cms.Web;

using Umbraco.Cms.Web.Surface;

using Umbraco.Framework;

using Umbraco.Hive;

using Umbraco.Cms.Web.Model;

using System.Linq;

List items = RoutableRequestContext.Application.Hive.QueryContent().Where(x => x.ContentType.Alias == "word").ToList();

This looks to be about right, cant confirm atm as its not hitting my controller for some wierd reason.

Hi Lee.

Could you perhaps include your entire code for the controller?

When I try to use you example I don't have Hive object on the context variable so I won't compile.

Could be that you include somthing that I've missed

This is a very good example as well:

Hm.. I don't get any items back from the query.

The x.ContentType.Alias == "word" is that the alias of the document property ?

I am talking about this:

That is what I would expect. Finally got mine to work. This is exactly what I have:

public class HelicopterController : UmbracoController

{

public override ActionResult Index(IUmbracoRenderModel model) {

List items = RoutableRequestContext.Application.Hive.QueryContent().Where(x => x.ContentType.Alias == "word").ToList();

return View();

}

}

Not sure if I have to use UmbracoController, but it works this way.

Hi Ishan,

this post is very old. But for what you want you can use UmbracoApiController or PluginController. Both have in context the UmbracoHelper where you will have access to the content.

https://our.umbraco.com/documentation/reference/routing/webapi/

For reference see the RestApi Project https://github.com/umbraco/UmbracoRestApi/blob/master/src/Umbraco.RestApi/Controllers/ContentController.cs

this simple sample.

using System.Collections.Generic;
using System.Linq;
using Umbraco.Web.WebApi;
using Umbraco.Web;

namespace MyNamespace
{
    public class ProductApiController : UmbracoApiController
    {

        public IEnumerable<Product> GetAllProducts()
        {

            return  Umbraco.TypedContentAtXPath("//product")
                    .Select(x=>
                new Product {
                Name = x.Name,
                Url= x.Url,
                MyProperty = x.GetPropertyValue<string>("MyPropertyAlias"),
                });

        }
    }

    public class Product
    {
        public string Name { get; set; }
        public string Url { get; set; }

        public string MyProperty { get; set; }
    }
}

is a poor example, but it shows how you can do

public IEnumerable<Product> GetAllProductsByCategoryName(string categoryName)
        {

            return  Umbraco.TypedContentAtXPath("//product")
                .Where(x=> x.GetPropertyValue<string>("category") == categoryName)
                    .Select(x=>
                new Product {
                Name = x.Name,
                Url= x.Url,
                MyProperty = x.GetPropertyValue<string>("MyPropertyAlias"),
                });

        }

This example is using the UmbracoHelper as a query. But you can do something with Examine, which I advise you to do. This link has an example with Umbraco web API

In this case you need is UmbracoAuthorizedApiController or UmbracoAuthorizedJsonController
