Fields and projections
Fields
Field identifiers simply are strings that identify a column in the context of a collection.
If we consider the following collections:
| Context | Field | Valid ? |
|---|---|---|
Books | "title" | Yes |
Books | "myAuthor:firstname" | Yes |
Books | "myReviews:content" | No, only relationships which yield one record can be traversed |
Reviews | "content" | Yes |
Reviews | "myBook:title" | No, reverse relations are not automatically defined in Forest Admin |
Projections
Projections are mainly used to fetch partial records and automatically fetch linked records.
Projections simply are an array of fields.
