When a data field of the type HTML String is dragged into a Handlebars snippet, the
expression gets three curly brackets to ensure that HTML characters are not escaped (see
"HTML values" on the next page).
It is possible to use logic in an expression, for example to display content only if a field has a
certain value. How this is done is described in another topic: "Using logic in a Handlebars
template: helpers" on page452.
Note
In OLConnect (as opposed to the original Handlebars library), numbers in Handlebars
expressions do not need to be surrounded by quotes. For example, to calculate 1+2 you
can write (add 1 2) instead of (add "1" "2").
Accessing data at different levels
A field or key name without a . or / is assumed to refer to a field or table at the root of the data
with which the template is rendered. There are a number of ways to access data that is not
located at the root.
l With . or / you can navigate down into the record or object. For example: {{Cars.Brand}}
and {{Cars/Brand}} refer to the same field.
Note that to access an item in a detail table or array directly, you also have to navigate
down. For example: Cars.Brand.Models.[0] refers to the first item in Models.
l @root represents the top level of the data.
If a template is rendered with the current record or part of it, @root refers to the root of the
current record.
With a JavaScript object, @root refers to the root level of the data that was passed to the
Handlebars template.
l The built-in helpers #each and #with dive into an object-property, giving you direct access
to its properties. (See "Using logic in a Handlebars template: helpers" on the facing page
and the documentation of Handlebars.)
l Use ../ to navigate one level up. This is particularly useful in #each and #with blocks.
Note
If a template is rendered with part of the current record, the template still has access
