Html Django-如何将您创建的主题公开？学习日志项目 问题

我正在尝试制作一个项目，在那里你可以制作主题，对于未经身份验证的用户，可以是私有的，也可以是公共的。然后，在每个主题中，您都可以创建多个条目，应用于该主题。现在，我正在尝试在我的new_topic.html中创建一个复选框，如果您选中它，它将计算为True，如果不选中，则计算为False。但是，当我选中复选框时，我很难使其计算为真。出于某种原因，页面中有两个适用于new_topic.html的复选按钮；一个有标签，一个只有一个盒子

我试过的 我已尝试重新创建db.sqlite3数据库。但那没用。 保存新主题变量时，我已尝试在我的新主题函数中使用request.POST.get'public'，False 代码 我的学习日志/models.py如下所示：

我似乎无法纠正这个错误。提前谢谢！非常感谢您的帮助。

您有：

  <input class="form-check-input" type="checkbox" value=True id="public">
      <label class="form-check-label" for="public">
       Make it public?
      </label>
  </input> # <<< this closing tag is wrong

因此，您将有：

<label class="form-check-label" for="public">
 Make it public?
</label>
<input class="form-check-input" type="checkbox" value=True id="public" />

标记输入不以关闭。只是，所以你不能在里面放标签。@guillermochamorro你能给我举个例子吗？这真的很有帮助。@Lauritis L.L.我发布了一个答案，我知道这就是你需要的？@guillermochamorro非常感谢！我得到了它。现在有一个复选框，如果您选中它，它的计算结果将为True！谢谢
