Python 如何使用同一复选框选择/取消选择/删除表中的多个django项？
我有这个项目表及其详细信息，我实现了一个方法，使用提交按钮“选择”一些项目，提交每个项目上的所有复选框 这是复选框的代码：Python 如何使用同一复选框选择/取消选择/删除表中的多个django项？,python,django,checkbox,django-templates,Python,Django,Checkbox,Django Templates,我有这个项目表及其详细信息，我实现了一个方法，使用提交按钮“选择”一些项目，提交每个项目上的所有复选框 这是复选框的代码： <input name='quiz-pids' id='checkbox-{{ quiz.id }}' type="checkbox" value="{{ quiz.id }}" required> 如您所见，我的函数“post”只接受测验PID，因为这一行request.post.getlist（'quick-pids'）。现在我的问题是，我还想删除和取消选
<input name='quiz-pids' id='checkbox-{{ quiz.id }}' type="checkbox" value="{{ quiz.id }}" required>
request.post.getlist（'quick-pids'）我试过的 我尝试添加更多功能：
