Django应用出现TemplateSyntaxError：无法解析'{{doc.id}}'剩余内容

The error you're seeing comes from incorrect syntax in your template's url tag. Inside Django's template tags (wrapped in {% %}), you don't use the double curly brace {{ }} syntax to reference variables—you can pass the variable directly.

The Problematic Line: #

<a href="{% url 'delete_feed' pk={{doc.id}} %}"><button type="button" class="btn btn-danger">Delete Item</button></a>

Corrected Template Code: #

Replace the above line with this:

<a href="{% url 'delete_feed' pk=doc.id %}"><button type="button" class="btn btn-danger">Delete Item</button></a>

Why This Works: #

When using the {% url %} tag, Django expects variable names without the {{ }} wrapper. Removing those braces lets the template engine correctly parse doc.id as the value for the pk parameter in your URL pattern.

Quick Check of Other Files: #

Your views.py and urls.py look correct:

• The delete_feed view properly accepts the pk argument, fetches the Feed object, deletes it, and returns a response.
• The URL pattern correctly captures an integer pk and maps to the delete_feed view with the name delete_feed.

A Note on Best Practices: #

While this fixes the syntax error, it's worth noting that using a GET request (via an anchor tag) for deletion isn't ideal for security. For better practice, consider using a POST form instead. This prevents accidental deletions from crawlers or users clicking links unintentionally.
