|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!

*/
Route::get('/', 'WelcomeController#index')->name('welcome');
Route::get('blog/posts/{post}', [PostsController::class, 'show'])->name('blog.show');
Route::get('blog/categories/{category}', [PostsController::class, 'category'])->name('blog.category');
Route::get('blog/tags/{tag}', [PostsController::class, 'tag'])->name('blog.tag');
Auth::routes();
Route::middleware(['auth'])->group(function () {
Route::get('/home', 'HomeController#index')->name('home');
Route::resource('categories', 'CategoriesController');
Route::resource('posts','PostsController');
Route::resource('tags','TagsController');
Route::get('trashed-posts','PostsController#trashed')->name('trashed-posts.index');
Route::put('restore-post/{post}', 'PostsController#restore')->name('restore-posts');
});
Route::middleware(['auth', 'admin'])->group(function () {

Answer 1

The error told that you don't have posts. Indeed it is. What you have is post() method on Category class, as evidently seen in this line:
public function post() {
You should change this ->with('posts', $category->posts()->simplePaginate()) to be:
public function category(Category $category) {
return view('blog.category')
->with('category', $category)
->with('posts', $category->post()->simplePaginate())
->with('categories', Category::all())
->with('tags', Tag::all());
}

Answer 2

In your model, you defined a post relationship whereas you use a posts relationship then, they're not the same one. You should replace post by posts because it's a to-many relationship.

Answer 3

Your relationship is post and you have multiple ->with('posts', $category->posts()->simplePaginate()). Can you change those to ->with('post') and try again?
