title: How to repeat a "block" in a django template
body: <p>I want to use the same <strong>{% block %}</strong> twice in the same django template. I want this block to appear more than once in my base template:</p>
  
  <pre><code># base.html
  &lt;html&gt;
      &lt;head&gt;
          &lt;title&gt;{% block title %}My Cool Website{% endblock %}&lt;/title&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;h1&gt;{% block title %}My Cool Website{% endblock %}&lt;/h1&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>And then extend it:</p>
  
  <pre><code># blog.html
  {% extends 'base.html' %}
  {% block title %}My Blog{% endblock %}
  
  # pictures.html
  {% extends 'base.html' %}
  {% block title %}My Pictures{% endblock %}
  
  # cats.html
  {% extends 'base.html' %}
  {% block title %}My Cats{% endblock %}
  </code></pre>
  
  <p>I will get an exception, as Django wants the block to appear only once:</p>
  
  <blockquote>
    <p><strong>TemplateSyntaxError at /</strong></p>
    
    <p><strong>'block' tag with name 'title' appears
    more than once</strong></p>
  </blockquote>
  
  <p>A quick and dirty solution would be duplicating the block <em>title</em> into <em>title1</em> and <em>title2</em>:</p>
  
  <pre><code># blog.html
  {% extends 'base.html' %}
  {% block title1 %}My Blog{% endblock %}
  {% block title2 %}My Blog{% endblock %}
  </code></pre>
  
  <p>But this is a violation of the <a href="http://docs.djangoproject.com/en/dev/misc/design-philosophies/#don-t-repeat-yourself-dry" rel="noreferrer">DRY</a> principle. It would be very difficult as I have a lot of inheriting templates, and also because I don't wanna go to hell ;-)</p>
  
  <p>Is there any trick or work-around to this problem? How can I repeat the same block in my template, without duplicating all the code?</p>
