• Skills of specifying a ternary condition for the input fields

You can conditionally execute formulas using Ruby's ternary syntax (popular shortcut for if-else statements). Ternary syntax is of the form: 

condition ? expression1 : expression2

Behavior

condition:

A boolean expression that evaluates to true or false.

expression1:

Returns this expression if the condition is true.

expression2:

Returns this expression if the condition is false.

Conditional formula example

In the following example, we conditionally pass in either the Full name or First name into the Message input field:

Here is a detailed explanation of what the ternary formula does:

1. Full name.present? will check if the Full Name pill has a value. If it has a value, it evaluates to true. If it has no value, it evaluates to false.
2. The second ? in the formula separates the condition to evaluate from the expressions to return.
3. If there is a value in the Full Name pill when the job is run, the value for Full Name will be mapped to the Message input.
4. If there is no value in the Full Name pill when the job is run, the value for First Name will be mapped to the Message input. Of course, if there's also no value in this First Name pill, the job will fail at this step, as Message is a required input field.
