Django templates problem — {% if object|length 4 %} raises TemplateDoesNotExist: 500.html

Question

I have the following in my template. ``` {% block content %} {% for album in albumsList %} {% if fotosList %}

item

{% if fotosList|length > 4 %} больше ▼ {% endif %}

{% endif %} {% endfor %} {% endblock %} ``` And it raises TemplateDoesNotExist: 500.html. If i write simple `{{ fotoList|length }}` it works okay.

Accepted Answer

This is a very old question. Since then, newer versions of Django support operators in if-statement out of the box, so the following code will work just fine:

```
{% if fotosList|length > 4 %}

{% endif %}
```
