Jinja Templating Guide: Part 2
Loops and Rebinding
In part 1 of this guide, we introduced Jinja2 and its templating basics. Now, let's delve into loops and how they're used in Jinja2.
Understanding Loops
Loops are essential for dynamic content generation in Jinja2. They allow you to iterate through sequences like lists, arrays, or dictionaries to create repetitive content.
The Loop Variable
The {% for %} tag introduces a loop block. Within this block, the {% for %} tag defines a loop variable that serves as the current element being iterated over.
Multi-Level Loops
Jinja2 supports nested loops. However, if you need to rebind the loop variable within an inner loop, use set to bind it to a different value.
Conclusion
Loops are a powerful tool in Jinja2 templating, enabling you to create dynamic and repetitive content. Understanding how to use loops and rebinding variables will enhance the flexibility and efficiency of your Jinja2 templates.
