Question

我正在尝试使用图像和标记的ID填充image_tag中间表，但是，我不断收到此错误，据我所知，表示表名不正确，即使它不是。它有列image_id和tag_id，它们采用无符号整数。

“SQLSTATE [42000]：语法错误或访问冲突：1103表名称'image_tag'不正确（SQL：插入image_tag（image_id，tag_id）值（17,12）））“

    public function uploadImage(Request $request){
            $this->validate($request, [
                'name' => 'required|max:120',
                'description' => 'max:120|nullable',
                'image' => 'required|max:1999'
            ]);

            $name = $request['name'];
            $description = $request['description'];
            $tag = $request['tags'];
            $userId = auth()->user()->id;
            $file = $request->file('image')->getClientOriginalName();
            $fileName = pathinfo($file, PATHINFO_FILENAME);
            $extension = $request->file('image')->getClientOriginalExtension();
            $fileNameToStore = $fileName.'_'.time().'.'.$extension;
            $fileNameToStore = str_replace(' ', '', $fileNameToStore);
            $path = $request->file('image')->storeAs('public/images/uploaded', $fileNameToStore);

            $image = new Image();
            $image->name = $name;
            $image->description = $description;
            $image->user_id = $userId;
            $image->file_name = $fileNameToStore;

            $image->save();
            $image->tags()->attach($tag);

            return redirect()->route('home');
    }

图片模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Image extends Model
{
    public function user(){
        return $this->belongsTo('App\User');
    }

    public function tags(){
        return $this->belongsToMany('App\Tag', 'image_tag ','image_id','tag_id');
    }
}

标记模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Tag extends Model
{
    public function images(){
        return $this->belongsToMany('App\Image', 'image_tag','tag_id','image_id');
    }
}

＆＃39; image_tag＆＃39;你写的：|

return $this->belongsToMany('App\Tag', 'image_tag ','image_id','tag_id');
