render(template text, input json|array|value)
Render a template with query results using Liquid syntax:
-- Single value
SELECT render('Total: {{ value }}', (SELECT count(*) FROM posts));
-- Multiple columns from one row
SELECT render(
'<h1>{{ title }}</h1><p>{{ text }}</p>',
(SELECT to_json(r) FROM (SELECT title, text FROM posts WHERE id = 1) r)
);
-- Loop over an array
SELECT render(
'{% for v in values %} {{ v }} {% endfor %}',
(SELECT array(SELECT title FROM posts))
);
-- Loop over multiple rows with multiple columns
SELECT render(
'{% for row in rows %} {{ row.title }} - {{ row.author }} {% endfor %}',
json_agg(to_json(posts.*))
) FROM posts;render_agg(template text, input record|json|value)
Aggregate render function – renders a template for each row:
-- Render each row from a derived table
SELECT render_agg('{{ title }} {{ text }}', props)
FROM (SELECT title, text FROM posts) AS props;
-- Render using json_build_object
SELECT render_agg(
'<article><h1>{{ title }}</h1></article>',
json_build_object('title', title)
) FROM posts;Using Stored Templates
SELECT render(
(SELECT template FROM templates WHERE id = 'my_tpl'),
(SELECT to_json(r) FROM (SELECT title, text FROM posts WHERE id = 1) r)
);PostgREST Integration
