我正在尝试在Laravel中的数据库表中插入数据，但是在按下提交时，页面将重定向到“ localhost / create”，并且错误是“ 找不到对象”。我的代码如下。请帮助我为什么会发生此错误，以及从哪里可以获取解决此问题的帮助。

def AverageWithThreshold(myList, threshold, emptyResult = None):
newList = [item for item in myList if item >= threshold]
if len(newList) == 0: return emptyResult
return sum(newList) / len(newList)
更改为

public interface ICollectableParent<out T> : ICollectableRelatedMonoBehaviour where T : Collectable
{
// This is allowed - T is used as a return type
T GetChild();
// This is *not* allowed - T is used as a parameter
void SetChild(T child);
}
更改为
Route::post('create','form@create');
并在form.blade.php
中Route::post('create', 'form@store');
更改为
<form action="/create" method="post" onsubmit="return validation()">
希望这会有所帮助。
编辑： 如果你写 路线:: post（'create'，'form @ store'）-> name（'create）;
然后查看
<form action="{{ route('create') }}" method="post" onsubmit="return validation()">
或者如果您写 路线:: post（'create'，'form @ store'）; 然后查看
<form action="{{ route('create') }}" method="post" onsubmit="return validation()">
