Django TemplateError when using if...else block inside for loop - django

Question

I have the following as part of my django template:
<nav>
<ul class="pagination">
{% if page.has_previous %}
<li>
<a href="{% url 'main:stream_detail' stream_id=stream.id %}?p={{page.next_page_number}}" aria-label="Previous">
<span aria-hidden="true">«</span>
</a>
</li>
{% else %}
<li class="disabled" aria-label="previous"><span aria-hidden="true">«</span></li>
{% endif %}
{% for i in paginator.page_range %}
(% if i == page.number %}
<li class="active">{{i}} <span class="sr-only">(current)</span></li>
{% else %}
<li>{{i}}</li>
{% endif %}
{% endfor %}
{% if page.has_next %}
<li>
<a href="{% url 'main:stream_detail' stream_id=stream.id %}?p={{page.next_page_number}}" aria-label="Next">
<span aria-hidden="true">»</span>
</a>
</li>
{% else %}
<li class="disabled" aria-label="next"><span aria-hidden="true">»</span></li>
{% endif %}
</ul>
</nav>
And I'm getting the following exception:
Invalid block tag on line 26: 'else', expected 'empty' or 'endfor'. Did you forget to register or load this tag?
Line 26 corresponds to the {% else %} clause inside the {% for %} loop. As fas as I can tell, this else clause correctly matches up with the if statement, but the template parser seems to expect a clause to match the for loop there.

Answer 1

You have a syntax error with the if tag in the for loop:
(% if
...should be
{% if

Answer 2

You used '(' instead of '{' on line (% if i == page.number %}
