Relationship Field (PRO)

A link from this record to records of another model — a product to its brand, an article to its authors.

Settings:

Setting	What it does
Relationship type	one_to_one, many_to_one, one_to_many, many_to_many
Picker	A dropdown, or a modal window for choosing — the modal only applies to the *_to_one kinds
Model	What is being linked to
Display	What the editor sees in the list, name by default
Value	What gets saved, id by default
Sort field, Sorting direction, Page size	Shape the list offered
Condition (where)	A filter, as JSON, so the list offers only what fits

The type decides the shape of the value: the two *_to_one kinds save a single identifier, the two *_to_many kinds save a list of them and let the editor pick several.

Output:

{foreach $authors as $id}
    …
{/foreach}

The field saves identifiers, not records

What lands in the value is ids — that is all. There is no ready-made snippet that turns them back into rows, so fetch them yourself, by the ids you stored:

{pbList(model = 'Author', where = '{"id:IN": ' ~ $authors ~ '}', tpl = 'author')}

Plan for that when you choose this field: it links records, it does not join them.
