Question

我有一个客户端模型，客户端属于许多客户端地址。在控制器上，show方法在客户端中传递，但如果我尝试访问地址方法，则会抛出以下错误。

1.1.1

show.blade.php

import React, { Component } from 'react';
import $ from 'jquery';
import './Navigation.scss';

class nav extends Component {

    componentDidMount = () => {
        // Hide Header on on scroll down
        var didScroll;
        var lastScrollTop = 0;
        var delta = 5;
        var navbarHeight = $('header').outerHeight();

        $(window).scroll(function(event){
            didScroll = true;
        });

    setInterval(function() {
        if (didScroll) {
            hasScrolled();
            didScroll = false;
        }
    }, 250);

    function hasScrolled() {
        var st = $(this).scrollTop();

        // Make sure they scroll more than delta
        if(Math.abs(lastScrollTop - st) <= delta) {
            return;
        }

        // If they scrolled down and are past the navbar, add class .nav-up.
        // This is necessary so you never see what is "behind" the navbar.
        if (st > lastScrollTop && st > navbarHeight){
            // Scroll Down
            $("header").removeClass("nav-down").addClass("nav-up");
        } else {
            // Scroll Up
            if(st + $(window).height() < $(document).height()) {
                $("header").removeClass("nav-up").addClass("nav-down");
            }
        }

        lastScrollTop = st;
    }

}

render() {

    return (
        <header className="fixed-top">
            <nav id="small-top-nav" className="nav navbar navbar-expand-lg nav-down">

                /* ALL LINKS CODE */

            </nav>

        </header>
    );
}

export default nav;

控制器

.nav-up {
    top: -2.5rem;
}

.nav-down {
    down: 2.5rem;
}

客户端模型

Invalid argument supplied for foreach() (View: /var/www/resources/views/clients/show.blade.php)

ClientsAddresses Model

@extends('layouts.app')
@section('content')
<section class="content-header">

客户迁移

/**
 * Display the specified resource.
 *
 * @param  \App\Client  $client
 * @return \Illuminate\Http\Response
 */
public function show(Client $client)
{
    //
    return view('clients.show')->with('client', $client);
}

客户地址迁移

class Client extends Model
{
    //
    use SoftDeletes;

    protected $table = 'clients';
    //protected $primaryKey  = 'id';

    const CREATED_AT = 'created_at';
    const UPDATED_AT = 'updated_at';


    protected $dates = ['deleted_at'];


    public $fillable = [
        'client_ref',
        'client_name',
        'is_active'
    ];

    /**
     * The attributes that should be casted to native types.
     *
     * @var array
     */
    protected $casts = [
        'id' => 'integer',
        'client_ref' => 'string',
        'client_name' => 'string',
        'is_active' => 'string',
        'created_at' => 'date',
        'updated_at' => 'date'
    ];

    /**
     * Validation rules
     *
     * @var array
     */
    public static $rules = [

    ];

    /**
     * @return \Illuminate\Database\Eloquent\Relations\HasMany
     **/
    public function addresses()
    {
        return $this->hasMany('ClientsAddresses');
    }

    /**
     * @return \Illuminate\Database\Eloquent\Relations\HasMany
     */
    public function history()
    {
        return $this->hasMany('ClientsHistory');
    }
}

外键迁移

class ClientsAddresses extends Model
{
    //
    protected $table = 'clients_addresses';

    const CREATED_AT = 'created_at';
    const UPDATED_AT = 'updated_at';

    public $fillable = [
        'client_id', 'address_type', 'is_active', 'address_line1', 'address_line2', 'address_line3',
        'city', 'country', 'postcode'
    ];

    public function Client(){
        return $this->hasOne('App\Models\Client');
    }
}

Answer 1

我认为你必须写下完整的路径：

public function addresses()
{
    return $this->hasMany('ClientsAddresses');
}


public function history()
{
    return $this->hasMany('ClientsHistory');
}

尝试：

return $this->hasMany('App\ClientsHistory');
 return $this->hasMany('App\ClientsAddresses');

Answer 2

您必须更改Laravel用于路径模型绑定的参数类型提示：

/**
 * Display the specified resource.
 *
 * @param  \App\Models\Client  $client
 * @return \Illuminate\Http\Response
 */
public function show(\App\Models\Client $client)
{
    return view('clients.show')->with('client', $client);
}

正如Ghyath Darwish指出的那样，你还必须在你的人际关系中指定整个班级名称如果两个模型共享相同的命名空间，请使用YourModel::class。
