英文:
Invalid block tag on line 117: 'endblock', expected 'empty' or 'endfor'. Did you forget to register or load this tag?
问题
It seems like you're experiencing an issue with your Django template code. The error message you're getting, "Invalid block tag on line 117: 'endblock', expected 'empty' or 'endfor'. Did you forget to register or load this tag?" indicates that there might be an issue with the use of the {% endblock %} tag.
To troubleshoot this issue, you can follow these steps:
-
Check for Missing Load Statement:
Ensure that you have loaded thestaticand other necessary template libraries at the top of your template file. You should have something like this at the beginning of your template:{% load static %}Make sure you have the appropriate
{% load ... %}statement for any other template tags you might be using as well. -
Verify Block Hierarchy:
Check if all your{% block ... %}tags have corresponding{% endblock %}tags. In your provided code, you seem to have a{% block body %}tag, and it appears that you have an{% endblock %}tag at the end of your template. Ensure that there are no unmatched block tags, and they are properly nested. -
Check for Syntax Errors:
Sometimes, syntax errors or typos can cause issues like this. Double-check that there are no syntax errors in your template, such as mismatched{% endfor %}or{% endif %}tags. The error might be occurring earlier in the template, affecting the block definitions later on. -
Look for Included Templates:
If you are extending another template (as indicated by{% extends 'shop/basic.html' %}), make sure that the base template (basic.html) also has the necessary block definitions and{% endblock %}tags. If you have extended a template and overridden a block, ensure that you have defined that block in the base template. -
Check for Template Caching:
Sometimes, template caching can cause issues where changes to templates are not immediately reflected. You can try clearing your Django template cache to ensure that you are working with the most up-to-date templates. -
Review Your Django Version:
Occasionally, issues like this may be related to specific versions of Django. Make sure you are using a compatible version of Django for your code. -
Debugging Output:
To debug further, you can add some debugging output in your template. For example, you can use{% debug %}to display the template context, or print values using{{ variable }}to check if the variables are being set correctly.
Once you've gone through these troubleshooting steps, you should be able to identify the root cause of the issue and resolve it. It's important to carefully review your template code and ensure that all block tags are properly defined and matched with their respective {% endblock %} tags.

This was my code in index.html and I am getting this error:
Invalid block tag on line 117: 'endblock', expected 'empty' or 'endfor'. Did you forget to register or load this tag?

你在第75行和88行有两个重复的for，并且在第106行有一个endfor。你需要处理这种情况，要么移除一个for，要么在该段落的末尾添加另一个endfor。

以下是翻译好的部分：
错误是由于您的代码中重复的“for循环块”引起的。另外，在扩展基本模板后，您应该在脚本的顶部加载静态资源。
这段代码应该可以工作：
{% extends 'shop/basic.html' %}
{% load static %}
{% block css %}

The error was caused by the duplicated for loop block in your code. Also you should load static at to top of the script, after extending the base template
