New deployment step for Open ID Server, a new multi-tenant platform built with Orchard Core and a very interesting demo about a custom admin tree module with taxonomy terms menu are waiting for you among other exciting news in this year's last This week in Orchard post! On Orchard Core Allow replacing a Liquid filter Orchard Core has several built-in Liquid filters. You can make your own Liquid filter if you implement the ILiquidFilter interface. However, it could be a valid use case if you would like to change the behavior of one of the predefined built-in filters and replace it with your own one. When registering a Liquid Filter to the service container, you have to do it in the ConfigureServices method of your Startup.cs file: public override void ConfigureServices(IServiceCollection services){ services.AddLiquidFilter<BuildDisplayFilter>("shape_build_display"); services.AddLiquidFilter<ContentItemFilter>("content_item_id");} Here you can see how to register the shape_build_display and content_item_id filters. But let's have a closer look at that AddLiquidFilter extension method! public static IServiceCollection AddLiquidFilter<T>(this IServiceCollection services, string name) where T : class, ILiquidFilter{ services.Configure<LiquidOptions>(options => options.FilterRegistrations.Add(name, typeof(T))); services.AddScoped<T>(); return services;} You could see that every time when you call AddLiquidFilter it adds your filter to the FilterRegistrations Dictionary. To be able to override an existing Liquid filter with your own, Jean-Thierry Kéchichian had to change this extension method a little bit and instead of adding the new filter to this Dictionary, just overwrite an existing one. public static IServiceCollection AddLiquidFilter<T>(this IServiceCollection services, string name) where T : class, ILiquidFilter{ services.Configure<LiquidOptions>(options => options.FilterRegistrations[name] = typeof(T)); services.AddScoped<T>(); return services;} Delete role should warn the user if the role has associated users Let's create a custom role and let's name it Blogger. Now let's create a new user and add the Blogger role to it. Now go back to the Roles page and delete the Blogger role. If you hit the Delete button you will see a warning message, that says this role is associated to existing user(s). Prefix resource manager definitions for sample themes When you would like to register your resource using the ResourceManifest, you have to do something similar: manifest .DefineScript("vendor-bootstrap") .SetDependencies("vendor-jQuery") .SetUrl("~/TheBlogTheme/vendor/bootstrap/js/bootstrap.min.js", "~/TheBlogTheme/vendor/bootstrap/js/bootstrap.js") .SetCdn("https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js", "https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.js") .SetCdnIntegrity("sha384-JjSmVgy...", "sha384-rkSXwmdF/9eRLkw/gNZG+1...") .SetVersion("4.3.1"); But what if you want to register Bootstrap again in your custom theme? You can do that of course, but when there are multiple resources with the same name, the resource manager takes the one with the highest version. // Use the highest version of all matchesif (resource == null || (resourceDefinition.Version != null && new Version(resource.Version) < version)){ resource = resourceDefinition;} To make things easier every predefined resource in the themes available in Orchard Core now has prefixes, which is the name of the theme. As you can see in the following code snippet, we registered the script for Bootstrap in the Blog theme with the name: TheBlogTheme-vendor-bootstrap. manifest .DefineScript("TheBlogTheme-vendor-bootstrap") .SetDependencies("TheBlogTheme-vendor-jQuery") .SetUrl("~/TheBlogTheme/vendor/bootstrap/js/bootstrap.min.js", "~/TheBlogTheme/vendor/bootstrap/js/bootstrap.js") .SetCdn("https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js", "https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.js") .SetCdnIntegrity("sha384-JjSmV6OrQ6VrjIEaF...", "sha384-rkSGcqMuXXwmdF/9eRLkw/gNZG+1zYut...") .SetVersion("4.3.1"); Deployment step for Open ID Server Head to Configuration -> Features and enable the OpenID Authorization Server module. Then you will get a new OpenID Connect option under the Security menu, where you can set up the authorization server, application, and scopes. If you set up the server in a way (the way how it's not important right now) you can import the settings of your server if you create a new deployment plan under Configuration -> Import/Export -> Deployment Plans. If you select the OpenID Server step, that will export all the Open ID Server settings. Just execute the deployment plan locally. After if you open the Recipe.json file in the zip you will find a section called OpenIdServer in the steps section. "steps": [ { "name": "OpenIdServer", "OpenIdServer": { "AccessTokenFormat": 0, "Authority": null, "CertificateStoreLocation": null, "CertificateStoreName": null, "CertificateThumbprint": null, "AuthorizationEndpointPath": "/connect/authorize", "LogoutEndpointPath": "/connect/logout", "TokenEndpointPath": "/connect/token", "UserinfoEndpointPath": "/connect/userinfo", "GrantTypes": [ "authorization_code", "refresh_token" ], "UseRollingTokens": false } }] In the specific content type list only allow the creation of the new content item of the selected type In the admin page, you have a Content Types submenu under the Content menu, where you can list all of the content items. If you click on one of those (for example the Article) there was a green New button where you can create any type of content item that is creatable. Now with a new improvement, the UI responds to the type of the selected content type and (if the Content Type is marked as creatable) you can create only a new content item of the selected type. Here you could see the green button has a text: New Article. New multi-tenant Orchard Core platform GovBuilt has over 30 years of government software experience. They worked with government employees, contractors, and citizens to build a best-in-class online solution that streamlines the permitting and licensing process. They offer a GovBuilt Platform built for Government. And they are using Orchard Core to build their solution! They have several tenants, and https://pottcounty.govbuilt.com/ is one of that! Demos Custom Admin Tree module with taxonomy terms menu You can find a new module in this repository called ThisNetWorks.OrchardCore.AdminTree and a new theme here, called ThisNetWorks.OrchardCore.Themes. If you clone these repositories and add them to your Orchard Core solution you will see a new module under Configuration -> Fetaures called ThisNetWorks Admin Tree Menus. ThisNetWorks Admin Tree module displays content items based on a URL tree or taxonomy structure. This module presents a taxonomy and it's associated terms in a tree menu. The primary purpose of this menu is intended to provide a way to manage complex taxonomies, in combination with a navigation system that makes manages those terms, and content items easier. Let's enable this feature! Now go Design -> Themes and make the ThisNetWorks Admin Theme as the current theme. This adapts the default admin theme to support the menu's on the left sidebar to include clickable entries on tree nodes (i.e. nodes that contain child items can also contain a link to an entry). To be able to test the current capabilities of this solution quickly, you can use a recipe (Configuration -> Recipes) called Categories, that contains sample content items and taxonomy for a taxonomy menu tree. After you run this recipe you should see the following admin menu structure. Here you can see a Categories option with several sub-items. Categories is a taxonomy with the Category term content type and this admin menu shows you the structure of the Categories taxonomy in a clickable way. For example, if you select Motorbike, the site lists you all the content items that have this taxonomy and the category of that is Motorbike. If you click on the blue Create Leaf Article button you can create a content item that has a permalink and the Categories taxonomy will be set to Motorbike by default. Let's see what will happen if you click on the View button near the Articles content item, that is the root term content item of the Categories taxonomy. As you can see, users in the front-end can navigate between the different levels of terms and when navigating between the different content items, you can use different kinds of badges to show the terms and of course, the URL reflects this change as well. This feature is under development and we hope that this will be part of Orchard Core soon! If you are interested in this demo don't forget to check this video on YouTube!
