Django添加项不匹配
我目前正在使用Django开发ToDo应用程序 我有两种模式待办事项和任务。我要创建Todo，在Todo项下我要创建任务项 因为我能够添加todo项和任务项 但是问题是，如果我想为数学添加任务项，那么默认情况下，所有任务项都会添加到第一个待办事项中。我认为这是因为在任务模式（弹出）表单中，我链接了函数url，以在单击add按钮时检索todo对象id，并在html中将引导模式（弹出）表单添加到a标记中。它不检索对应的todo项目id，而是获取第一个todo项目id（请参阅下图） 型号.pyDjango添加项不匹配,django,django-models,django-views,django-forms,django-templates,Django,Django Models,Django Views,Django Forms,Django Templates,我目前正在使用Django开发ToDo应用程序 我有两种模式待办事项和任务。我要创建Todo，在Todo项下我要创建任务项 因为我能够添加todo项和任务项 但是问题是，如果我想为数学添加任务项，那么默认情况下，所有任务项都会添加到第一个待办事项中。我认为这是因为在任务模式（弹出）表单中，我链接了函数url，以在单击add按钮时检索todo对象id，并在html中将引导模式（弹出）表单添加到a标记中。它不检索对应的todo项目id，而是获取第一个todo项目id（请参阅下图） 型号.py cla

// This event is fired when the modal has been made visible to the user
$('#taskModal').on('shown.bs.modal', function (e) {
let id = e.relatedTarget.id // get the id from the button
$('#addTask').attr('action', `/add_todo/${id}/`); // update the action with the id
});
</script>
添加
//当模式对用户可见时触发此事件
$（'#taskModal'）.on（'show.bs.modal'，函数（e）{
让id=e.relatedTarget.id//从按钮获取id
$（'#addTask'）.attr（'action'，`/add#todo/${id}/`）//用id更新操作
});
此外，您还必须改进变量和函数名称，我们为其他开发人员编写代码 您正在创建n个具有相同id的taskModal模态，这是错误的，并导致在所有add操作中仅打开具有id taskModal的第一个模态的错误。html中的每个元素都需要有唯一的id。我想对您的代码做很多更改，但现在让我们让您的代码正常工作 将添加按钮的数据目标从data target=“#taskmodel”更改为data target=“#taskmodel”{{{i.id}}”，类似地将taskmodel的id从taskmodel更改为taskmodel{{i.id}
您需要对更新todo进行类似的更改。在updateTodo模式中，为什么实例不工作？您尚未定义todoModal，我无法在main中看到它。htmlI已在main.HTMLY中添加了UpdatetodoModal。它现在应该工作正常。不，它不工作。显示的是空表单，而不是实例值。
