    Accessing Helper Methods

    Hey!

    I'm installing the Azure CDN Toolkit for the first time, and I'm struggling to gain access the Helper methods inside my strongly typed object model.

    I can see the extensions are contained inside "Our.Umbraco.AzureCDNToolkit.UrlHelperRenderExtensions" however, I can't figure out how to get this context into my C# code.

    namespace client.project.Logic.Model.Media
    {
        public class Image : BaseContentType
        {
    
            public Image(IPublishedContent content)
                : base(content)
            {
            }
    
            public string Url
            {
                get
                {
                    return this.GetCropUrl(imageCropMode: ImageCropMode.Max, width: 1200);
                }
            }
        }
    }

    What do you have in your BaseContentType?

    Here we go, a few helpers and a way of bringing back Typed Media/Content.

    using System;
    using Umbraco.Core.Models;
    using Umbraco.Core.Models.PublishedContent;
    using Umbraco.Web;
    
    namespace project.client.Logic.Model.Content
    {
        public abstract class BaseContentType : PublishedContentModel
        {
    
                private UmbracoHelper _umbracoHelper;
    
                protected BaseContentType(IPublishedContent content)
                        : base(content)
                {
                        _umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
                }
    
    
                protected T GetProperty<T>(string propertyAlias)
                {
                        return this.GetPropertyValue<T>(propertyAlias);
                }
    
                protected bool PropertyExists(string propertyAlias)
                {
                        return this.HasProperty(propertyAlias);
                }
    
                protected IPublishedContent GetMediaByAlias(string alias)
                {
                        var str = this.GetPropertyValue<string>(alias);
    
                    if (str != null)
                    {
                            return _umbracoHelper.TypedMedia(str);
                    }
                    return null;
                }
    
    
    
        }
    }

    It's an interesting one with moving the helpers in Umbraco to HtmlHelper and UrlHelper extension methods rather than IPublishedContent which I've continued in this package it means you need a helper to use the methods in this context.

    I would go with this.

    public abstract class BaseContentType : PublishedContentModel
    {
    
        private UmbracoHelper _umbracoHelper;
        internal UrlHelper UrlHelper;
    
        protected BaseContentType(IPublishedContent content)
                : base(content)
        {
            _umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
            UrlHelper = new UrlHelper();
        }
    

    and then

    public class Image : BaseContentType
    {
    
        public Image(IPublishedContent content) : base(content)
        {
        }
    
        public string Url
        {
            get
            {
                return this.UrlHelper.GetCropCdnUrl(this.Content, imageCropMode: ImageCropMode.Max, width: 1200).ToString();
            }
        }
    }
    

    I will think about adding methods that aren't extension methods to this package as I think they are useful on their own for scenarios such as this...

    Thanks Jeavon! I've successfully implemented everywhere, just waiting for the blobs to be available on the CDN endpoint :-) Thanks! Laurie

    Cool, it can take quite a few hours before they appear, it says 90 minutes but I've never seen it be that quick!

    This helped me since I have code outside of Razor views where I want to return Crops from the CDN and came unstuck! Thanks

    The files are there now!

    Just having some issues with the ImageProcessor part of it >.<

    Using the latest (AzureBlobCache.1.1.2.0) as my storage is in the UK.

    Have checked all the DLL's are present, and versions are correct, triple checked config files!

    System.MissingMethodException: Method not found: 'System.String ImageProcessor.Web.Helpers.ImageHelpers.GetExtension(System.String, System.String)'.

    Odd, could you try updating the WindowsAzure.Storage NuGet package to the latest (I have a hunch something's slightly different with new UK accounts)?

    To double check you have the following versions?

    • ImageProcessor.Web.Plugins.AzureBlobCache v1.1.2
    • ImageProcessor.Web v4.6.4
    • ImageProcessor v2.4.4
    • ImageProcessor.Web.Config v2.3.0

    Updating WindowsAzure.Storage from 6.2.0 to 7.2.1 resolved this issue.
