Boolean logic in Rewst workflows
Boolean values and their role in automation
Boolean values represent simple yes/no conditions, like on/off or true/false. They define rules and logic in workflows by evaluating conditions.
Boolean values are fundamental in automation workflows, controlling decision-making and process flow. Understanding Boolean logic helps ensure that workflows are efficient, reliable, and easy to maintain.
Key boolean concepts
Boolean values: Represent
true
orfalse
, similar to1
(on) and0
(off).Logical operators:
and
,or
,not
determine conditions in workflows.Comparison operations: Evaluate conditions (e.g.,
user_role == "admin"
).Custom conditions in workflows: Enable transitions based on Boolean evaluations.
Boolean operators in Rewst workflows
Boolean logic controls workflow decisions using these key operators:
and
β Requires both conditions to be true.Example:
user_logged_in and is_admin
or
β Requires at least one condition to be true.Example:
is_manager or is_admin
not
β Inverts a Boolean value.Example:
not user_logged_in
(returnstrue
ifuser_logged_in
isfalse
).
Boolean logic in action
True and false = false β Both conditions must be true for
and
to returntrue
.True or false = true β Only one condition needs to be true for
or
to returntrue
.Not false = true β Flips the Boolean value to its opposite.
Best practices for boolean logic in Rewst
To ensure efficiency and maintainability, follow these best practices.
Structuring logical conditions
Group logic with parentheses: Ensures conditions execute in the correct order.
Example:
(is_admin and is_active) or is_super_admin
Use
in
for cleaner conditions:Before:
if role == "admin" or role == "super_admin"
After:
if role in ["admin", "super_admin"]
Simplifying boolean expressions
Use ternary operators for concise logic:
Syntax:
variable = value_if_true if condition else value_if_false
Example:
status = "Active" if is_active else "Inactive"
Leverage short-circuit evaluation:
Skips unnecessary checks by placing the most likely condition first.
Example:
if user_logged_in and is_admin:
(Skipsis_admin
check ifuser_logged_in
isfalse
.)
