如何用多個條目更新表格。 Laravel 5

Question

已更新。我有一種形式將數據添加到兩個不同的表（文章&交易）。一篇文章有​​很多交易。一筆交易有一篇文章。有多個的交易與dealname不同，用戶在創建和編輯表單上輸入。我可以創建一個有很多交易的文章，我可以使用Deals表中的數據填充編輯表格，但當我使用文章控制器更新我的'交易'表時，它只更新每個'交易名'與最後一個dealname是輸入的。我只需要更新'dealname'列，因爲所有其他列將保持不變。如果我刪除表單的dealname/deals部分，我可以更新。

如何正確更新交易表？我知道我必須改變我的文章控制器的更新功能。

我使用Laravel 5.

在文章表有：ID，標題，圖片，說明，地址。 Deals表格包含：id，dealname，article_id，dayID。

文章控制器 - 更新

 public function update(ArticleRequest $request, $id) 
     { 
     $article = Article::find($id); 
      if($request->hasFile('image')){ 
       // photo saving stuff. 
      } 
     $article->fill($request->input())->save(); 
//Get IDs of deals to be updated. 
     $dealID = Deal::all()->lists('dealname', 'id'); 
     $dealID = $dealID->toArray(); 
     $dealID = array_keys($dealID); 

     $deals = $request->input('dealname'); 

    foreach($deals as $deal) { 
      Deal::whereIn('id', $dealID)->update(['dealname' => $deal]); 

      } 
      return redirect('/'); 
     } 

表

{!! Form::model($article, ['route' => ['articleUpdate_path', $article->id], 'files' => true, 'method' => 'PATCH']) !!} 

    {!! Form::label('title','TITLE') !!} 
    {!! Form::text('title', null, ['class' => 'form-control']) !!} 
    {!! $errors->first('title','<p class="error">:message</p>')!!} 

    {!! Form::label('image','PHOTO') !!} 
    {!! Form::file('image', null, ['class' => 'form-control']) !!} 

    {!! Form::label('description','DESCRIPTION') !!} 
    {!! Form::textarea('description', null, ['class' => 'form-control']) !!} 

@foreach ($article->deals as $deal) 

    @if($deal->dayID == '1') 
    {!! Form::label('dealname','Monday') !!} 
    {!! Form::text('dealname[]', $deal->dealname, null, ['class' => 'form-control', 'id' => '1']) !!} 
    @endif 

    @if($deal->dayID == '2') 
    {!! Form::label('dealname','Tuesday') !!} 
    {!! Form::text('dealname[]', $deal->dealname, null, ['class' => 'form-control', 'id' => '2']) !!} 
    @endif 
    @if($deal->dayID == '3') 
     {!! Form::label('dealname','Wednesday') !!} 
     {!! Form::text('dealname[]', $deal->dealname, null, ['class' => 'form-control', 'id' => '3']) !!} 
    @endif 
@endforeach 

    {!! Form::label('address','ADDRESS') !!} 
    {!! Form::text('address', null, ['class' => 'form-control']) !!} 

    {!! Form::close() !!} 

文章控制器-store

public function store(ArticleRequest $request) 
    { 
     $image_name = $request->file('image')->getClientOriginalName(); 
     $request->file('image')->move(base_path().'/public/images', $image_name); 
     $article = ($request->except(['image'])); 
     $article['image'] = $image_name; 

     $article = Article::create($article); 

// GET INPUT 
     $deals = $request->input('dealname'); 

// GET ID OF ARTICLE 
     $articleID = $article->id; 
// N is the day id that increments 
     $n = 1; 
     foreach($deals as $deal) { 

      Deal::create(['dealname' => $deal, 'article_id' => $articleID, 'dayID' => $n++]); 

     } 

     return redirect()->route('articles_path'); 

    } 

Article模型

class Article extends Model 
{ 
    public function deals() 
    { 
     return $this->hasMany('App\Deal'); 
    } 
protected $fillable = array('title', 'photo', 'description', 'address'); 
} 

DEAL模型

class Deal extends Model 
{ 
    public function article() 
    { 
     return $this->belongsTo('App\Article')->withTimestamps(); 
    } 
    protected $fillable = array('dealname', 'article_id', 'dayID'); 
}

我真的不知道要充分了解你的問題，但將這樣的事情可能是你的情況非常有用：

public function update(ArticleRequest $request, $id) { 
    $article = Article::findOrFail($id); 
    if($request->hasFile('image')){ 
     // photo saving stuff. 
    } 
    $article->update($request->all()); 
    $article->deals->where('dayID',1)->first()->dealname = $request->input('dealname')[0]; 
    $article->deals->where('dayID',1)->first()->save(); 
    $article->deals->where('dayID',2)->first()->dealname = $request->input('dealname')[1]; 
    $article->deals->where('dayID',2)->first()->save(); 
    $article->deals->where('dayID',3)->first()->dealname = $request->input('dealname')[2]; 
    $article->deals->where('dayID',3)->first()->save(); 
} 

他們只是你在表單中使用的那3天嗎？

編輯： 您也可以嘗試使用for循環。這是未經測試的代碼，所以你可能想要優化它:)

public function update(ArticleRequest $request, $id) { 
    $article = Article::findOrFail($id); 
    if($request->hasFile('image')){ 
     // photo saving stuff. 
    } 
    $article->update($request->all()); 
    for($i = 0; $i < sizeof($request->input('dealname')); $i++) { 
     $article->deals->where('dayID',($i + 1))->first()->dealname = $request->input('dealname')[$i]; 
     $article->deals->where('dayID',($i + 1))->first()->save(); 
    } 
}
