I’m new to laravel and created a mini program using a bit of help of twitter bootstrap.

I’m trying to access this route:

http://127.0.0.1:8000/posts/create

And I get these errors:

2/2 ErrorException in 73427cb411f683691ba00d0846f7eda3c61bff74.php line 4:

Here are my routes at the moment:

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)

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppPost;

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)

<?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppPost;
use AppComment;

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 Blades in question i think:
(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>
@endsection

(new-post.blade.php)

@extends('master')

@section('content')
    <div class="col-sm-8 blog-main">
        <h1>Publish a Post<hr /></h1>

        <form method="POST" action="/posts">
            {{ csrf_field() }}

            <div class="form-group">
                <label for="title">Title:</label>
                <input type="text" class="form-control" id="title" name="title">
            </div>

            <div class="form-group">
                <label for="body">Body</label>
                <textarea name="body" id="body" class="form-control" cols="30" rows="10"></textarea>
            </div>

            <div class="form-group">
                <button type="submit" class="btn btn-primary">Publish</button>
            </div>

            @include('partials.error')
        </form>
    </div>
@endsection

(master.blade.php)

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="">

    <title>Blog Template for Bootstrap</title>

    <!-- Bootstrap core CSS -->
    <link rel="stylesheet" href="{{ URL::asset('css/bootstrap.min.css') }}">

    <!-- Custom styles for this template -->
    <link rel="stylesheet" href="{{ URL::asset('css/blog.css') }}">
    <link rel="stylesheet" href="{{ URL::asset('css/style.css') }}">
</head>

<body>      
    @include('partials.nav')

    <div class="container">

        <div class="row">
            @yield('content')

            @include('partials.sidebar')

        </div><!-- /.row -->

    </div><!-- /.container -->

    @include('partials.footer')

</body>
</html>

Here are my models if it helps:
(Post.php)

<?php

namespace App;

class Post extends Model
{
    public function comments()
    {
        return $this->hasMany(Comment::class);
    }
}

(Comment.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.

The problem is that your create route is listed after the general posts/{id} route. Laravel handles every segment after the /posts/ as an id and ignores the “special” create route.

Swap those two lines like this:
```
Route::get('/posts/create', 'PostController@showForm');
Route::get('/posts/{id}', 'PostController@showById');
```
Furthermore I’d suggest you to use resource controllers which makes your life a bit easier with routing!

Change your route

From
```
Route::get('/posts/{id}', 'PostController@showById');
```
To
```
Route::get('/posts/{id}', 'PostController@showById')->where('id', '[0-9]+');
```

If you use resource controllers and still have the same problem , you should check your database because something within the columns may be NULL.
