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.

["id", "title", "author:firstName"] // for books
