Tag Management

CMS kit provides a tag system to tag any kind of resources, like a blog post.

Options

The tag system provides a mechanism to group tags by entity types. For example, if you want to use the tag system for blog posts and products, you need to define two entity types named BlogPosts and Product and add tags under these entity types.

CmsKitTagOptions can be configured in the domain layer, in the ConfigureServices method of your module class.

Example: Adding tagging support for products

Configure<CmsKitTagOptions>(options =>
{
    options.EntityTypes.Add(new TagEntityTypeDefiniton("Product"));
});

If you're using the blog feature, the ABP framework defines an entity type for the blog feature automatically.

CmsKitTagOptions properties:

  • EntityTypes: List of defined entity types(TagEntityTypeDefiniton) in the tag system.

TagEntityTypeDefiniton properties:

  • EntityType: Name of the entity type.
  • DisplayName: Display name of the entity type. You can use a user friendly display name to show entity type definition on the admin website.
  • CreatePolicies: List of policy/permission names allowing users to create tags under the entity type.
  • UpdatePolicies: List of policy/permission names allowing users to update tags under the entity type.
  • DeletePolicies: List of policy/permission names allowing users to delete tags under the entity type.

The Tag Widget

The tag system provides a tag widget to display associated tags of a resource that was configured for tagging. You can simply place the widget on a page like below:

@await Component.InvokeAsync(typeof(TagViewComponent), new
{
  entityType = "Product",
  entityId = "..."
})

entityType was explained in the previous section. entityId should be the unique id of the product, in this example. If you have a Product entity, you can use its Id here.

  • Tag (aggregate root): Represents a tag in the system.
EntityTag

An entity tag represents a connection between the tag and the tagged entity.

  • EntityTag(entity): Represents a connection between the tag and the tagged entity.

Repositories

This module follows the Repository Best Practices & Conventions guide.

Following custom repositories are defined for this feature:

  • ITagRepository
  • IEntityTagRepository

Domain services

This module follows the Domain Services Best Practices & Conventions guide.

Tag Manager

Application layer

Application services

  • TagAdminAppService (implements ITagAdminAppService).
  • EntityTagAdminAppService (implements IEntityTagAdminAppService).
  • TagAppService (implements ITagAppService).

Database providers

Common

Table / collection prefix & schema

All tables/collections use the Cms prefix by default. Set static properties on the CmsKitDbProperties class if you need to change the table prefix or set a schema name (if supported by your database provider).

Connection string

This module uses CmsKit for the connection string name. If you don't define a connection string with this name, it fallbacks to the Default connection string.

See the connection strings documentation for details.
