堆栈跟踪是代码调试和分析的关键工具,用于在应用程序执行时查看函数调用堆栈和变量值。在 Django 500.html 文件中包含堆栈跟踪可以采取以下步骤:
print()
函数打印堆栈跟踪信息。try:
# Execute your function or view function here
pass
except Exception as e:
# Print the exception information with a line break for better readability
print(traceback.format_exc())下面是一个更完整的示例:
import pprint
import traceback
def do_something():
try:
# Your code here to execute
func1()
except Exception as e:
# Handle exception in your code
print(traceback.format_exc())
def func1():
try:
# Your code here to execute
func2()
except Exception as e:
# Handle exception in your code
print(traceback.format_exc())
def func2():
try:
# Your code here to execute
# 调用 do_something 函数会调用其他函数,直到到达这个函数。在此情况下,打印堆栈跟踪信息将显示在 Django 的 500.html 视图中,用于调试和解决问题。
do_something()
except Exception as e:
# Handle exception in your code
print(traceback.format_exc())
{% extends 'base.html' %}
{% block error_messages %}
{{ super() }}
<p class="error">An error occurred.</p>
<p class="error">Please see the browser console for details.</p>
{% endblock %}
