CMS Kit: Comments

CMS kit provides a comment system to add comments feature to any kind of resource, like blog posts, products, etc.


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

CmsKitCommentOptions can be configured in the domain layer, in the ConfigureServices method of your module. Example:

Configure<CmsKitCommentOptions>(options =>
    options.EntityTypes.Add(new CommentEntityTypeDefinition("Product"));

If you're using the blog feature, the ABP framework defines an entity type for the blog feature automatically. You can easily override or remove the predefined entity types in Configure method like shown above.

CmsKitCommentOptions properties:

  • EntityTypes: List of defined entity types(CmsKitCommentOptions) in the comment system.

CommentEntityTypeDefinition properties:

  • EntityType: Name of the entity type.

The Comments Widget

The comment system provides a commenting widget to allow users to send comments to resources on public websites. You can simply place the widget on a page like below.

@await Component.InvokeAsync(typeof(CommentingViewComponent), 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.

Database providers


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.
