Question

这是我的观看代码：

<!-- form.blade.php -->
<form class="form-horizontal" action="{{ isset($article) ? URL('console/articles/'.$article->id) : URL('console/articles') }}" method="POST">
  @if (isset($article))
    <input name="_method" type="hidden" value="PUT">
  @endif
  @unless (empty($errors->first()))
      <div class="alert alert-danger alert-dismissible" role="alert">
        <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        ...
      </div>
  @endunless
  <input type="hidden" name="_token" value="{{ csrf_token() }}">
  <div class="form-group {{ $errors->has('title') ? 'has-error' : '' }}">
    <label for="article_title" class="col-sm-2 control-label">...</label>
    <div class="col-sm-8">
      <input type="text" name="article[title]" id="article_title" class="form-control" placeholder="..." value="{{isset($article) ? $article->title : old('title')}}">
      {!! $errors->first('title', '<p class="help-block">:message</p>') !!}
    </div>
  </div>
  <div class="form-group {{ $errors->has('body') ? 'has-error' : '' }}">
    <label for="article_body" class="col-sm-2 control-label">...</label>
    <div class="col-sm-8">
      <textarea name="article[body]" id="article_body" cols="30" rows="10" class="form-control">{{isset($article) ? $article->body : old('body')}}</textarea>
      {!! $errors->first('body', '<p class="help-block">:message</p>') !!}
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-8">
      <button type="submit" class="btn btn-success">...</button>
    </div>
  </div>
</form>

并请求验证人：

// StoreArticleRequest.php
// ...
public function rules()
{
  switch ($this->method()) {
    case 'GET':
    case 'DELETE': {
      return [];
    }
    case 'POST': {
      return [
        'article.title' => 'required|unique:articles|max:255',
        'article.body' => 'required'
      ];
    }
    case 'PUT':
    case 'PATCH': {
      return [
        'article.title' => 'required|unique:articles,title,'.Route::input('articles').'|max:255',
        'article.body' => 'required'
      ];
    }
    default:
      break;
  }
  return [];
}
// ...

在发送创建方法的请求后，它会引发

SQLSTATE [42S22]：未找到列：1054未知列＆＃39; article.title＆＃39;   在＆＃39; where子句＆＃39;

SQLSTATE [42S22]：未找到列：1054未知列＆＃39; article.title＆＃39;   在＆＃39; where子句＆＃39; （SQL：从articles选择count（*）作为聚合   其中article。title = test）

更新

这是我的控制器代码：

// ArticlesController.php
// ...
public function store(StoreArticleRequest $request)
{
  $article = new Article($request->input('article'));
  if ($article->save()) {
    return redirect('console/articles')->with('success', '...');
  } else {
    return redirect()->back()->withInput();
  }
}

// ...
public function update(StoreArticleRequest $request, $id)
{
  $article = Article::find($id);
  if ($article->update($request->input('article'))) {
    return redirect('console/articles')->with('success', '...');
  } else {
    return redirect()->back()->withInput();
  }
}

// ...

Answer 1

在 StoreArticleRequest.php 文件

中更改规则

case 'POST': {
  return [
    'article.title' => 'required|unique:articles,title|max:255',
    'article.body' => 'required'
  ];
}

如果您未在唯一验证中指定列名，则需要将键视为列名。

Answer 2

而不是使用文章[title]作为输入名称使用title作为输入名称，而在规则中使用title而不是article.title
