Root Cause

Accessing a query parameter that is missing, and trying to convert it to int without a default.

generic

中文

访问缺失的查询参数，并在没有默认值的情况下尝试将其转换为int。

Workarounds

  1. 95% success 
    Use request.GET.get('param', 0) to provide a default value.
  2. 90% success 
    Use try-except with int() and handle ValueError/TypeError.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    If the parameter is missing, get() returns None, causing TypeError.

  2. 70% fail

    May lead to unexpected behavior or silent failures.
