title: How to call conditional statements on template tags with no arguments django
body: <p>I'm trying to display html content based on what a template tag function returns.</p>
  
  <p><strong>template.html</strong></p>
  
  <pre><code>{% load custom_tags %}
  {% if return_something == True %}
    # display something
  {% endif %}
  </code></pre>
  
  <p><strong>custom_tags.py</strong></p>
  
  <pre><code>from my_app.models import MyModel
  
  @register.simple_tag()
  def return_something():
      if MyModel.objects.filter(active=True).exists()
          return True
      else:
          return False
