我只是想 crud 系统。对于控制器存储功能，我的代码是
public function store(Request $request)
{
Article::create([
'user_id' => auth()->id(),
'content' => $request->content,
'live' => (boolean)$request->live,
'post_on' => $request->post_on

存储数据就足够了，但是当我想编辑文章并再次保存时，我的编辑功能代码是什么？我不知道。我在编辑功能中尝试相同的代码，它会创建新文章而不是更新。那么编辑功能的正确代码是什么？谢谢

Resource controller method for update is update(). Eloquent method for update()is update()too, so you can do this:
更新的资源控制器方法是update(). Eloquent 方法update()也是update()如此，所以你可以这样做：
public function update(Request $request, $id)
{
Article::where('id', $id)->update($request->all());
return redirect('/articles');
}
You also can use the same controller and Eloquent method for both crerate and update data updateOrCreate()method.
您还可以对创建和更新数据updateOrCreate()方法使用相同的控制器和 Eloquent方法。

you can use
您可以使用
public function update(Request $request, $id)
{
$article = Article::find($id);
$article->fill($request->all());
}
sure you should add Your column attributes to $fillable array in Your model
确保您应该将您的列属性添加到您的模型中的 $fillable 数组中
protected $fillable = ['user_id', 'content', 'live'];

You can also update it as object format like this.
您也可以像这样将其更新为对象格式。
public function update(Request $request, $id)
{
$article = Article::find($id);
$article->user_id = auth()->id();
$article->content = $request->content;
$article->live = (boolean)$request->live;
$article->post_on = $request->post_on;
$article->save();
}`

//route//
Route::any('/update/{id}', 'ProductController@update');
//controller//
public function update(Request $request, $id) {
$product = $request - > all();
Product::find($id) - > update($product);
return redirect('/product') - > with('message', 'Success', compact('product'));
}

If you auto-generate resource controller for a specific Model using php artisan make:model -a Articalthen you have the update()function like below:
如果您使用自动生成特定模型的资源控制器，php artisan make:model -a Artical那么您将拥有如下update()功能：
public function update(Request $request, Article $article)
{
//
}
Here, Lavarel automatically fetch the Articleobject into $article. So, you can save the $requestdata like below:
在这里，Lavarel 自动将Article对象提取到$article. 因此，您可以保存如下$request数据：
public function update(Request $request, Article $article)
{
$article->update($request->all());
return redirect()->route('article.index'); // or your desired location :)
}

public function update(Request $request, $id)
{
$info = array('user_id' =>$request->user()->id,
'content' => $request->content, 'live'=>$request->live);
DB::table('article')->where('id', $id)->update($info);
session()->flash('success', 'Update Successfully');
return redirect('/article');
}

First, you are having two actions right, the create and update, so for a real crud in laravel you might have these two in a separated logic methods the store()and update():
首先，您有两个正确的操作，创建和更新，因此对于 laravel 中的真正 crud，您可能将这两个操作放在单独的逻辑方法 the store()and 中update()：
/**
* This is a resource create method which is a HTTP POST.
*/
public function store(Request $request) {
// create a new item in database
}
/**
* This is a resource update which is a HTTP PUT METHOD.
*/
public function update(Request $request, $id) {
// update the item in database
}
You set up your routes withPOSTfor creating and PUTto update then your doing a proper crud resource.
你设置你的路线以POST创建和PUT更新然后你做一个适当的 crud 资源。
I recommend you to separate the create logic off the update logic and if you have sort of unique data then you should validate its value before creating a new resource.
我建议您将创建逻辑与更新逻辑分开，如果您有某种独特的数据，那么您应该在创建新资源之前验证其值。
