I have a thymeleaf template that iterates over a List (chore completion objects), and prints a letter when an if condition is met (when a chore completion object has a certain chore_id and person_id). This results in a string of letters. How can I print out the number of letters rather than the string of repeating letters? Is thymeleaf able to have an iteration counter variable that could be used?
<tr th:each="chore: ${chores}">
<td>
<span th:each="completion : ${completions}">
<span th:if="${(completion.chore?.chore_id) == chore.chore_id and (completion.person?.person_id) == persons[0].person_id}">T</span>
</span>
</td>
</tr>

It is perfectly fine to create a data structure in your controller that allows you to easily output what you need.
For example, you could create a record (Or a class if you are on an older Java version) that has a field for the count you want to show and add instances of such records to your Model:
