django template child data in nested loop

To access child data in a nested loop in Django templates, you can follow these steps:

1. Start by defining your parent loop using the {% for %} template tag. This loop will iterate over the parent data.

2. Within the parent loop, use the {% for %} template tag again to define the child loop. This loop will iterate over the child data related to each parent item.

3. To access the child data, use the dot notation along with the variable representing the parent item. For example, if the parent item is parent_item and the child data is stored as a related field called child_data, you can access it using {{ parent_item.child_data }}.

4. If the child data is stored as a queryset or a list, you can further iterate over it using another {% for %} loop within the child loop. This allows you to access and display the individual child items.

5. To access specific attributes of the child items, use the dot notation again, similar to step 3. For example, if the child item has an attribute called name, you can access it using {{ child_item.name }}.

Here's an example to illustrate these steps:

{% for parent_item in parent_data %}
  <h2>{{ parent_item.name }}</h2>
  <ul>
    {% for child_item in parent_item.child_data %}
      <li>{{ child_item.name }}</li>
    {% endfor %}
  </ul>
{% endfor %}

In this example, parent_data represents the data for the parent loop, and child_data represents the related child data. The name attribute is accessed both for the parent and child items using the dot notation.
