  1. POHow to repeat a "block" in a django template
    text
    copied!<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>
