{% apibody %} r.row → value {% endapibody %}
Returns the currently visited document.
{% infobox %}
Note that row
does not work within subqueries to access nested documents; you should use anonymous functions to access those documents instead. (See the last example.)
{% endinfobox %}
Example: Get all users whose age is greater than 5.
r.table('users').filter(r.row('age').gt(5)).run(conn, callback)
Example: Access the attribute 'child' of an embedded document.
r.table('users').filter(r.row('embedded_doc')('child').gt(5)).run(conn, callback)
Example: Add 1 to every element of an array.
r.expr([1, 2, 3]).map(r.row.add(1)).run(conn, callback)
Example: For nested queries, use functions instead of row
.
r.table('users').filter(function(doc) {
return doc('name').eq(r.table('prizes').get('winner'))
}).run(conn, callback)
