問題文
A team wants to add a card that shows data from their internal system on the entity pages. Which option correctly identifies the pair of pieces of work that implies, and where each of them goes?
選択肢
- A frontend extension attached to the entity page, and a backend plugin or an existing service for the data.
- Only a backend plugin, since cards are generated from the interface that it exposes, with one card per method.
- A backend module attached to the catalog's extension point, which contributes both the data and the card so that the entity page picks them up together when the entity is rendered.
- Only a frontend extension, since the catalog already holds all entity data.
