我正在尝试解决这个问题,在这里我尝试使用laravel 5.2中的更新方法来编辑多个文件。
当我运行并保存过程时,返回以下错误:
QueryException in Connection.php line 729:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'property_id' cannot be null (SQL: insert into `files` (`name`, `property_id`, `updated_at`, `created_at`) values (58bf2825d39d9.jpg, , 2017-03-07 17:37:41, 2017-03-07 17:37:41))
这是我的财产迁移表和您的关系

这是我的文件迁移表和您的关系

这是我的财产模型

在这里,我展示了控制器的部分问题所在
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Intervention\Image\Exception\NotReadableException;
use Illuminate\Support\Facades\Input;
use App\Http\Requests;
use App\Client;
use App\Category;
use App\Term;
use App\Province;
use App\Municipality;
use App\Property;
use App\Currency;
use App\User;
use App\File;
use Image;
use View;
class PropertyController extends Controller
{
public function update(Request $request, $id)
{
//dd($request->input());
$updated = Property::findorFail($id);
$properties = $request->all();
$property_id = $request->get('property_id');
$updated->fill($properties)->save();
// -- Images update method -- //
$images = $request->file('avatar');
foreach ($images as $image)
{
$rules = array(
'avatar' => 'required|mimes:png,gif,jpeg,jpg|max:20000'
);
$validator = \Validator::make(array('avatar'=> $image), $rules);
if (! $validator->passes())
{
return redirect()->back()->withErrors($validator);
}
$extension = $image->getClientOriginalExtension();
$filename = uniqid() . '.' . $extension;
$path = public_path() . 'uploads/products/';
//dd($extension);
Image::make($image)->resize(300, 200)->save( public_path('uploads/products/' . $filename ) );
//Move file into uploads folder
$image->move($path, $filename);
//Insert file name in db
//dd($image);
$image = File::create([
'name' => $filename,
'property_id' => $property_id
]);
}
// -- End method -- //
return redirect()->route('properties.index')
->with('success','Propiedad actualizada satisfactoriamente!!!');
}
这是$ image = File :: create方法之前的测试,返回以下值:
我试图做的是替换文件并删除它们,以便它们不会累积在存储这些图像的目录中。
您需要验证您的property_id是在表单请求中发送的。如果您错过添加它的操作,则将其添加为隐藏字段。
<Input type="hidden" name="property_id" value="{{$properties->id}}" >
您看到的错误是因为property_id
表上的files
列不可为空。
如果您希望此列接受空值,则需要在迁移中允许它:
$table->integer('property_id')->unsigned()->nullable();
当然,您可能不希望该值为null,所以...
$property_id = $request->get('property_id');
您确定在上一行中填充了$property_id
变量吗?应该不是:
$property_id = $request->input('property_id');
SQLSTATE [23000]:违反完整性约束:1048列'c_nm'不能为空(SQL:插入category
(c_nm
)值(?))从3天开始我的项目中发生Theis错误我重新创建了我的整个项目,并且新表也存在,但是发生了同样的问题。现在请帮助我,说我现在该怎么办???
