how to use a django variable in an <a> tag's href?-CodePudding

I want to create a list of entries in which each entry is linked to its page like this: wiki/entry-title. I'm using a for loop to add <li>s to HTML. here's the code:

<ul>
  {% for entry in entries %}
    <li><a href="">{{ entry }}</a></li>
  {% endfor %}
</ul>

urlpattern:

path('wiki/<str:title>', views.entry, name='entry')

what should I type in href to link the <li> to wiki/entry?

You can set your value in url as

<ul>
    {% for entry in entries %}
        <a href="/wiki/{{entry.value}}"><li>{{ entry }}</li></a>
  {% endfor %}
</ul>

Its better to use {% url %} [Django-doc] template tags as

<ul>
    {% for entry in entries %}
        <a href="{% url 'your-url-name' entry.value %}"><li>{{ entry }}</li></a>
  {% endfor %}
</ul>

NOTE : change value with your value accordingly. For e.g. {{entry.value}} or {{entry.title}} or {{entry.id}}

There is a clear example in the django docs

<ul>
  {% for yearvar in year_list %}
    <li><a href="{% url 'news-year-archive' yearvar %}">{{ yearvar }} Archive</a></li>
  {% endfor %}
</ul>

In django, the template parser always handles django code first, then html/javascript. So you would insert a django variable into an anchor tag the same way you'd insert it anywhere in the template and the parser will replace it before it tries to render the html. If it's a django url, you can use the {% %} format as referenced in the previous answer, and if it's a url that's perhaps stored on the object, you can just use {{ }} (like {{ entry.wiki_url }}). You can also use text for some of the url and a variable for part. So if you have a wiki site that has a base url of, for instance, https://mywiki.com you'd write the href like:

<ul>
  {% for entry in entries %}
    <a href="https://mywiki.com/{{entry.title}}"><li>{{ entry.title }}</li></a>
  {% endfor %}
</ul>
