Defining resources in StellarAdmin


Central to StellarAdmin is the concept of "resources". A resource is a representation of the underlying domain models or entities that your application makes use of. For example, a blogging application may have resources for entities such as Blog post, Author and Category.

Defining a resource

You define resources in StellarAdmin when you register the StellarAdmin services in your Startup.ConfigureServices method. The AddStellarAdmin() method takes an optional configure parameter that gives you access to the StellarAdminBuilder class that allows you to register resources.

The builder has an AddResource<TResource> method you call to declare a resource. The TResource generic parameter specifies the model the resource will be managing. In the code below, we register a new resource that will manage the Author class.

services.AddStellarAdmin(builder =>
    builder.AddResource<Author>(rb =>
        // ...

The AddResource<TResource> method has a configure parameter that gives you access to the ResourceDefinitionBuilder<TResource> class that will allow you to define the resource. It allows you to do the following:

  1. Define the data source of the resource through the UseDataSource() method
  2. Define the fields of the resource through the AddField() method
  3. Define the primary key of the resource through the HasKey() method
  4. Define the display field of the resource through the HasDisplay() method
  5. Register custom actions for the resource through the AddSimpleAction(), AddConfirmationAction(), and AddFormAction() methods.
