Rewsty Jinja Ninja-Jinja2 Templates with Enhanced Features

Example

{{ [user.id for user in CTX.users if user.active] }}

Scenario

In a workflow where you need to extract user IDs of only active users, instead of manually filtering and iterating over the list, you can use list comprehensions. This results in cleaner and more readable code, with the ability to process large datasets efficiently. It’s especially useful in situations where data transformation needs to be quick and minimalistic without intermediate variables.

Example

{% try %}{{ user.name }}{% catch %}Unknown User{% endtry %}

Scenario

This feature allows users to wrap code inside a try-catch block to gracefully handle potential errors, such as missing or undefined variables. For instance, if you’re dealing with an uncertain dataset where user names might be missing, you can provide a fallback message instead of an error. This improves the robustness of the workflow by ensuring the template runs without interruptions even when encountering unexpected situations.

Example

{{ user.name | capitalize }}

Scenario

Custom filters extend the functionality of Jinja2 by allowing users to format or transform data in specialized ways. For example, the `capitalize` filter can be applied to a user's name to ensure that the name is displayed with proper capitalization. Users can create workflows that clean or standardize their data based on specific requirements, such as trimming whitespace or converting all text to lowercase or uppercase.
