我是Laravel的初学者,现在尝试在我的网站上构建一个简单的搜索栏。

但是我收到了这个错误:

  

Class'产品'找不到

有人可以告诉我,我在控制器中忘记了什么吗?

在索引上搜索表单

 <ul class="searchbar">
    <form action="/search" class="light" method="POST" role="search">
 {{ csrf_field() }}
        <input type="text" class="form-control" name="q" placeholder="Find your item" />
        <input type="submit" value="Search" />
    </form>

search.blade.php:

@extends('master.main')

@if(Auth::check())

@section('main-content')

  @component('master.notification')

    @slot('size')

    col-md-8 col-md-offset-2

    @endslot

    @slot('title')

    Product Search

    @endslot

    <div class="container">
    @if(isset($products))
    <h2>Product Search</h2>
        <table class="table table-striped">
            <thead>
                <tr>
                    <th>Product</th>
                    <th>Description</th>
                </tr>
            </thead>
            <tbody>
                @foreach($products as $dummy)
                <tr>
                    <td>{{$dummy->name}}</td>
                    <td>{{$dummy->description}}</td>
                </tr>
                @endforeach

            </tbody>
        </table>
        {!! $products->render() !!}@endif
    </div>
        <div class="container">
            @if(isset($details))
            <p> The Search results for <b> {{ $query }} </b> are :</p>
            <h2>Product Search</h2>
            <table class="table table-striped">
                <thead>
                    <tr>
                        <th>Product</th>
                        <th>Description</th>
                    </tr>
                </thead>
                <tbody>
                    @foreach($details as $products)
                    <tr>
                        <td>{{$products->name}}</td>
                        <td>{{$products->description}}</td>
                    </tr>
                    @endforeach
                </tbody>
            </table>

            @if($details){!! $details->render() !!}@endif
            @elseif(isset($message))
            <p>{{ $message }}</p>
            @endif
        </div>

  @endcomponent

@stop

@endif

web.php:

Route::get ( '/', function () {
    $mydatabase = products::paginate(25);
    return view ( 'search' )->withproducts($mydatabase);
} );

Route::any ( '/search', function () {
    $q = Input::get ( 'q' );
    if($q != ""){
    $products = products::where ( 'name', 'LIKE', '%' . $q . '%' )->orWhere ( 'description', 'LIKE', '%' . $q . '%' )->paginate (5)->setPath ( '' );
    $pagination = $products->appends ( array (
                'q' => Input::get ( 'q' ) 
        ) );
    if (count ( $products ) > 0)
        return view ( 'search' )->withDetails ( $products )->withQuery ( $q );
    }
        return view ( 'search' )->withMessage ( 'No Products found. Try to search again !' );
} );

错误来自:

  

Route :: get(&#39; /&#39;,function(){       $ mydatabase = products :: paginate(25);

如何productsProduct::paginate定义或必须在web.php ProductController@...使用?是的,我发现它不是我的数据库表products;)我认为Product而不是products是正确的,对吗?

/App/Product.php:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Storage;

class Product extends Model
{
    public function category(){
      return $this->belongsTo('App\Category');
    }
    public function seller(){
      return $this->belongsTo('App\User');
    }
    public function buyer(){
      return $this->belongsTo('App\User');
    }

    public function bids(){
      return $this->hasMany('App\Bid');
    }
    public function purchases(){
      return $this->hasMany('App\Purchase');
    }



}

如果您的产品型号为Product,那么您的代码中就会出现拼写错误。

Route::get ( '/', function () {
$mydatabase = Products::paginate(25);
return view ( 'search' )->withproducts($mydatabase);
} );

您的代码更改为products::paginateProduct::paginate()

希望这有帮助

尝试将products::paginate替换为\App\products::paginate

Laravel是命名空间,因此无法通过正确的名称找到类。

答案 2 :(得分:0)

您必须在控制器的开头添加(导入您的类产品)(适用于您的情况的web.php)

Object_id | term-taxonomy_id
20145     | 113
20145     | 132
20651     | 113
20365     | 114

用命名空间(类产品的路径)替换命名空间例如:\ app 最好使用控制器ProductController并重新定义你的函数

答案 3 :(得分:0)

Laravel 5促进了模型和控制器等名称空间的使用。您的模型位于App命名空间下,因此您的代码需要像下面这样调用它:

Route :: get('/',function(){

    $myDatabase= \App\Products::paginate(25);

});

解决!非常感谢你的帮助!

我必须添加

  

使用App \ Product;

到我的web.php文件,效果很好!
