Here are my routesat the moment:
以下是我目前的路线：
Route::get('/posts', 'PostController@index');
Route::get('/posts/{id}', 'PostController@showById');
Route::get('/posts/create', 'PostController@showForm');
Route::post('/posts', 'PostController@store');
Route::post('/posts/{post}/comments', 'CommentController@store');
My Controllers: (PostController)
我的控制器：（PostController）
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Post;
class PostController extends Controller
{
public function index() {
$posts = Post::latest()->get();
return view('index', compact('posts'));
}
public function showById($id)
{
$post = Post::find($id);
return view('show-solo', compact('post'));
}
public function showForm()
{
return view('new-post');
}
public function store(Request $request) {
$this->validate(request(), [
'title' => 'required|min:2',
'body' => 'required|min:10'
]);
Post::create([
'title' => $request->title,
'body' => $request->body
]);
return redirect('/posts');
}
}
(CommentController)
（评论控制器）
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Post;
use App\Comment;
class CommentController extends Controller
{
// Convention to POST ADD
public function store(Post $post)
{
Comment::create([
'body' => request('body'),
'post_id' => $post->id
]);
// return back() works too
return back();
}
}
The Bladesin question i think: (show-solo.blade.php)
我认为有问题的刀片：（show-solo.blade.php）
@extends('master')
@section('content')
<div class="col-sm-8 blog-main">
<div class="blog-post">
<h2>Post number: {{ $post->id }}</h2>
<h2 class="blog-post-title">
<a class="title-link" href="/posts/{{ $post->id }}">{{ $post->title }}</a>
</h2>
<!-- {{ $post->created_at->toFormattedDateString() }} -->
<p class="blog-post-meta">{{ $post->created_at->diffForHumans() }} by <a href="#">Mark</a></p>
{{ $post->body }}
<hr />
@include('partials.error')
@include('partials.post-comment')
</div>
</div>

Here are my modelsif it helps: (Post.php)
如果有帮助，这是我的模型：（Post.php）
<?php
namespace App;
class Post extends Model
{
public function comments()
{
return $this->hasMany(Comment::class);
}
}
(Comment.php)
（评论.php）
<?php
namespace App;
class Comment extends Model
{
public function post()
{
return $this->belongsTo(Post::class);
}
}
Before the posts/create route works fine and now it won't. When I try to remove the route Route::get('/posts/{id}', 'PostController@showById'); the post/create route works properly again. What Am I missing? Any help would be greatly appreciated, Thanks.
在帖子/创建路线工作正常之前，现在不会了。当我尝试删除路由 Route::get('/posts/{id}', 'PostController@showById'); post/create 路由再次正常工作。我错过了什么？任何帮助将不胜感激，谢谢。
回答by manniL
The problem is that your createroute is listed after the general posts/{id}route. Laravel handles every segment after the /posts/ as an id and ignores the "special" createroute.
问题是您的create路线列在一般posts/{id}路线之后。Laravel 将 /posts/ 之后的每个段作为 id 处理，并忽略“特殊”create路由。
Swap those two lines like this:
像这样交换这两行：
Route::get('/posts/create', 'PostController@showForm');
Route::get('/posts/{id}', 'PostController@showById');
Furthermore I'd suggest you to use resource controllerswhich makes your life a bit easier with routing!
此外，我建议您使用资源控制器，这使您的路由生活更轻松！
回答by Quynh Nguyen
Change your route
改变你的路线
From
从
Route::get('/posts/{id}', 'PostController@showById');
To
到
Route::get('/posts/{id}', 'PostController@showById')->where('id', '[0-9]+');
回答by sejfi hoxha
If you use resource controllersand still have the same problem , you should check your database because something within the columns may be NULL.
如果您使用资源控制器并且仍然有同样的问题，您应该检查您的数据库，因为列中的某些内容可能为 NULL。
