这里的场景是：
我有两张桌子。
1. User
2. Post
用户可以登录，登录和注销，他可以创建自己的个人资料，他可以更新它
发布表包含个人用户信息，当用户创建他的配置文件时，该表包含数据，用户也可以从该表更新数据。
问题是我可以创建用户，但无法更新。如何解决此问题？
Undefined property:
Illuminate'Database'Eloquent'Collection::$first_name (View:
C:'xampp'htdocs'protfolio'resources'views'update.blade.php)
这是我的用户模型：
<?php
namespace App;
use Illuminate'Foundation'Auth'User as Authenticatable;
class User extends Authenticatable
{
protected $fillable = [
'name', 'email', 'password',
];
protected $hidden = [
'password', 'remember_token',
];
public function post()
{
return $this->hasOne('App'Post');
}
}
这是后模型：
<?php
namespace App;
use Illuminate'Database'Eloquent'Model;
class Post extends Model
{
public function user()
{
return $this->belongsTo('App'User'); //Profile is your profile model
}
}
这是邮局管理员：
<?php
namespace App'Http'Controllers;
use Illuminate'Http'Request;
use Illuminate'Http'Response;
use App'Http'Requests;
use App'Post;
use App'User;
use Illuminate'Support'Facades'Auth;
use Illuminate'Support'Facades'Storage;
use Illuminate'Support'Facades'File;
class PostController extends Controller
{
public function getDashboard()
{
$posts = Post::all();
return view('dashboard',['posts'=>$posts]);
}
public function postUpdate(Request $request)
{
$this->validate($request,[
'first_name'=> 'required|max:120',
'middle_name'=> 'required|max:120',
'last_name' => 'required|max:120',
'gender'=> 'required',
'dob'=>'required',
'nationality'=>'required',
'nid'=>'required',
'email' => 'required|email|unique:users',
'phone_no'=>'required',
'about_me'=>'required',
]);
$post = Post::find($request['postId']);
if (Auth::user() != $post->user) {
return redirect()->back();
}
$post->first_name = $request['first_name'];
$post->middle_name = $request['middle_name'];
$post->last_name = $request['last_name'];
$post->gender = $request['gender'];
$post->dob = $request['dob'];
$post->nationality = $request['nationality'];
$post->nid = $request['nid'];
$post->email = $request['email'];
$post->phone_no = $request['phone_no'];
$post->about_me = $request['about_me'];
$post->update();
return redirect()->route('dashboard');
}
public function postCreate(Request $request){
$this->validate($request,[
'first_name'=> 'required|max:120',
'middle_name'=> 'required|max:120',
'last_name' => 'required|max:120',
'gender'=> 'required',
'dob'=>'required',
'nationality'=>'required',
'nid'=>'required',
'email' => 'required|email|unique:users',
'phone_no'=>'required',
'about_me'=>'required',
]);
$post = new Post();
$post->first_name = $request['first_name'];
$post->middle_name = $request['middle_name'];
$post->last_name = $request['last_name'];
$post->gender = $request['gender'];
$post->dob = $request['dob'];
$post->nationality = $request['nationality'];
$post->nid = $request['nid'];
$post->email = $request['email'];
$post->phone_no = $request['phone_no'];
$post->about_me = $request['about_me'];
$message='There was an Error';
if( $request->user()->post()->save($post)){
$message = "Profile Created successfully";
}
return redirect()->route('dashboard')->with(['message' => $message]);
}
}
这是用户控制器：
<?php
namespace App'Http'Controllers;
use Illuminate'Http'Request;
use App'Http'Requests;
use App'User;
use App'Post;
use Illuminate'Support'Facades'File;
use Illuminate'Support'Facades'Auth;
use Illuminate'Support'Facades'Storage;
class UserController extends Controller
{
public function getAccount()
{
$posts = Post::all();
return view('update',['user'=>Auth::user()],['posts'=>$posts]);
}
public function getCreate()
{
return view('create',['user'=>Auth::user()]);
}
}
这是我的更新.blade.php
@extends('layouts.master')
@section('content')
@include('includes.message-block')
<div class="container" >
<h3> Create course </h3>
{!! Form::open(array('route' => 'update','class'=>'form-horizontal','method'=>'POST')) !!}
{!! Form::token(); !!}
{!! csrf_field() ; !!}
<div class="form-group">
<label>First Name</label>
<input type="text" name="first_name" class="form-control" value="{{$posts->first_name}}">

<div class="form-group">

</div>
<button type="submit" class="btn btn-default">Submit</button>
{!! Form::close() !!}
</div>
@endsection
$posts->first()->first_name，并在更新页面中的所有其他变量中使用相同的变量
问题似乎与用户模型类定义有关，请在此处尝试以下代码：
用户模型
namespace App;
use Illuminate'Auth'Authenticatable;
use Illuminate'Database'Eloquent'Model;
class User extends Model
{
use Authenticatable;
...
我认为你的问题在这里：
public function getAccount()
{
$posts = Post::all();
return view('update',['user'=>Auth::user()],['posts'=>$posts]);
}
Post:：all（）从表中获取所有帖子，而不是属于用户的帖子。（我想这就是你想要的）。
要获得与当前登录用户相关联的帖子，您可以尝试以下操作：
$posts = Auth::user()->post
