大佬教程收集整理的这篇文章主要介绍了根据 laravel-8 中的 product_id 显示所有数据，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
这是我的项目表。谁能帮我？我坚持了 2 天
我可以在这里显示产品表的数据
这是产品表
这个 ID 项目表
product_ID 存储数据。在我的项目表中，我有三个 product_ID 1,2,3。我想根据 product_ID 显示它们。例如，如果我想显示 product_ID 2 的数据，那么在我的 index.blade.php 中将只显示 product_ID 2 的数据，而不是 product_ID 1 和 3
这是我的 projectController.php 的 index() 方法
public function index()
{
$product = Product::with('projects')->where('user_iD',Auth::ID())->firstOrFail();
$projects = $product->projects()->latest()->paginate(20);
return vIEw('projects.index',compact('projects'))
->with('i',(request()->input('page',1) - 1) * 5);
}
这是我在 ProjectController.php 中的 show() 方法
public function show(Project $project)
{
return vIEw('projects.show',compact('project'));
}
这是用户模型 user.php
public function Products(){
return $this->hasmany('App\Models\Product');
}
public function Project(){
return $this->hasmany('App\Models\Project');
}
这是产品模型product.php
class Product extends Model
{
use HasFactory;
protected $fillable = [
'name','detail','image','color','logo','user_iD'
];
public function User(){
return $this->belongsTo(User::class);
}
public function Project(){
return $this->hasmany(Project::class);
}
}
class Project extends Model
{
use HasFactory;
protected $fillable = [
'chapter_name','sub_section_name','title_1','description_1','image_1','image_2','image_3','title_2','description_2','title_3','description_3','vIDeo_1','vIDeo_2','vIDeo_3','user_iD','product_ID'
];
public function User(){
return $this->belongsTo(User::class);
}
public function Product(){
return $this->belongsTo(Product::class);
}
}
这是 projectimport.php，我可以在其中上传 execl
class Projectsimport implements ToModel,WithheadingRow
{
public function __construct()
{
Project::where('product_ID',Product::where('user_iD',Auth::ID())->pluck('ID')->last())->delete();
}
/**
* @param array $row
*
* @return \Illuminate\Database\Eloquent\Model|null
*/
public function model(array $row)
{
return new Project([
'chapter_name' => $row['chapter_name'],'sub_section_name' => $row['sub_section_name'],'title_1' => $row['title_1'],'description_1' => $row['description_1'],'image_1' => $row['image_1'],'image_2' => $row['image_2'],'image_3' => $row['image_3'],'title_2' => $row['title_2'],'description_2' => $row['description_2'],'title_3' => $row['title_3'],'description_3' => $row['description_3'],'vIDeo_1' => $row['vIDeo_1'],'vIDeo_2' => $row['vIDeo_2'],'vIDeo_3' => $row['vIDeo_3'],'user_iD' => auth()->user()->ID,'product_ID' => Product::where('user_iD',Auth::ID())->pluck('ID')->last()
]);
}

您传递的是整个模型而不是 id 列
public function index()
{
$product = Project::whereIn('product_id',Product::where('user_id',Auth::id())->pluck('id')->toArray())->firstOrFail();
$projects = Project::where('product_id',$product->id)->latest()->paginate(20);
return view('projects.index',compact('projects'))
->with('i',(request()->input('page',1) - 1) * 5);
}
class Project extends Model
{
public function product()
{
return $this->belongsTo('App\Models\Product');
}
}
class Product extends Model
{
public function projects()
{
return $this->hasmany('App\Models\Project');
}
}
并像这样访问它：
public function index()
{
$product = Product::with('projects')->where('user_id',Auth::id())->firstOrFail();
$projects = $product->projects()->latest()->paginate(20);
return view('projects.index',1) - 1) * 5);
}
更新：
public function index()
{
$products = Product::with('projects')->where('user_id',Auth::id())->firstOrFail();
$projects = $products->map(function($product) {
return $product->projects()->latest()->first();
})->flatten();
return view('projects.index',1) - 1) * 5);
}
