Compare with:

self.encode(value, options = nil)

Dumps objects in JSON (JavaScript Object Notation). See www.json.org for more info.

ActiveSupport::JSON.encode({ team: 'rails', players: '36' })
# => "{\"team\":\"rails\",\"players\":\"36\"}"

Generates JSON that is safe to include in JavaScript as it escapes U+2028 (Line Separator) and U+2029 (Paragraph Separator):

ActiveSupport::JSON.encode({ key: "\u2028" })
# => "{\"key\":\"\\u2028\"}"

By default, it also generates JSON that is safe to include in HTML, as it escapes <, >, and &:

ActiveSupport::JSON.encode({ key: "<>&" })
# => "{\"key\":\"\\u003c\\u003e\\u0026\"}"

This can be changed with the escape_html_entities option, or the global escape_html_entities_in_json configuration option.

ActiveSupport::JSON.encode({ key: "<>&" }, escape_html_entities: false)
# => "{\"key\":\"<>&\"}"

Parameters

value req
options opt = nil
