I am using Laravel-nestedset and am having a hard time querying the ancestrosOf my category model.
This is what I am trying to do:
Works
http://carnival-experts.test/categories (this gives me a list of all categories)
http://carnival-experts.test/categories/carnival-games (this gives me a list of all Carnival Games)
Does Not Work
http://carnival-experts.test/categories/carnival-games/large-scale-games (this shows me a list of Carnival Games and not the Large Scale Games category)
I am sure this is just my lack of understanding--any help appreciated.

my questions may be a bit of a beginner, but please be patient, thank you
I want to display the projects related to each category in the following code in the second foreach, but now all the projects are displayed
view
#foreach($categories as $category)
<div id="section-{{ $category->id }}" class="section">
<h3 class="fnt_gh fnt-color">{{ $category->category_project }}</h3>
<div class="bigBox">
<div class="container1">
#foreach($projects as $project)
<article class="barghabi">
<a href="#" data-cat="news" data-state="vic">
<img src="{{ $project->image_project }}" alt="">
<h6 class="fnt_gh" style="line-height: normal;">
{{ $project->title_project }}
</h6>
</a>
</article>
#endforeach
<div class="content"></div>
</div>
</div>
</div>
#endforeach
And a categories table and a project table whose models and relationships are as follows:
class Project extends Model
{
protected $fillable = [
'title_project' ,
'period_project' ,
'description_project' ,
'manager_project' ,
'phone_project' ,
'email_project' ,
'image_project'
];
public function categories()
{
return $this->belongsToMany(Category::class);
}
}
class Category extends Model
{
protected $fillable = ['category_project' , 'icon_project'];
public function projects()
{
return $this->belongsToMany(Project::class);
}
}
and pivot :
Schema::create('category_project', function (Blueprint $table) {
$table->unsignedBigInteger('category_id');
$table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
$table->unsignedBigInteger('project_id');
$table->foreign('project_id')->references('id')->on('projects')->onDelete('cascade');
$table->primary(['category_id' , 'project_id']);
$table->timestamps();
});
controller:
class ProjectController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
*/
public function index()
{
$categories = Category::all();
$projects = Project::all();
return view('home.fa.pages.project.index', compact('categories' , 'projects' ));
}
}
You are calling #foreach($projects as $project) within your loop. You've defined $projects as all projects. Instead, use #foreach($category->projects as $project).
#foreach($categories as $category)
<div id="section-{{ $category->id }}" class="section">
<h3 class="fnt_gh fnt-color">{{ $category->category_project }}</h3>
<div class="bigBox">
<div class="container1">
#foreach($category->projects as $project)
<article class="barghabi">
<a href="#" data-cat="news" data-state="vic">
<img src="{{ $project->image_project }}" alt="">
<h6 class="fnt_gh" style="line-height: normal;">
{{ $project->title_project }}
</h6>
</a>
</article>
#endforeach
<div class="content"></div>
</div>
</div>
</div>
#endforeach
I'm not sure what's in $category->category_project but having a property with the same name as your pivot table is bound to create confusion. You should keep column names simple and readable, not append _project to each one!
i have two table categories and annonces between them hasMany relationship belongsTo, each category has several annonces, how to display for each category the annonces corresponds, in my example it displays all the annonces.
landing-page.blade.php
<div id="simplelastads">
<h2>Les dernières annonces</h2>
<div class="contentads">
#foreach($categories as $category)
<div class="simpleadsemploi">
<h3>{{ $category->name }}</h3>
#foreach($annonces as $annonce)
<div class="tab_left">
<div class="li-child">
{{ $annonce->titre }}
<span>{{ $annonce->ville }}({{ $annonce->hay }})</span>
</div>
<div class="readmore">Voir plus...</div>
</div>
#endforeach
</div>
#endforeach
</div>
</div>
Annonce.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Annonce extends Model
{
public function category() {
return $this->belongsTo('App\Category');
}
}
Category.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Category extends Model
{
protected $guarded = [];
protected $table = 'category';
public function annonces(){
return $this->hasMany('App\Annonce');
}
}
LandingPageController.php
public function index()
{
$categories = Category::all();
$annonces = Annonce::all();
return view('landing-page')->with(
[
'categories'=> $categories,
'annonces' => $annonces
]);
}
Correct the controller and the view like this
landing-page.blade.php
<div id="simplelastads">
<h2>Les dernières annonces</h2>
<div class="contentads">
#foreach($categories as $category)
<div class="simpleadsemploi">
<h3>{{ $category->name }}</h3>
#foreach($category->annonces as $annonce)
<div class="tab_left">
<div class="li-child">
{{ $annonce->titre }}
<span>{{ $annonce->ville }}({{ $annonce->hay }})</span>
</div>
<div class="readmore">Voir plus...</div>
</div>
#endforeach
</div>
#endforeach
</div>
</div>
Use the eager loading for the annonces to improve performance with('annonces')
LandingPageController.php
public function index()
{
$categories = Category::with('annonces')->get();
return view('landing-page')->with([
'categories'=> $categories
]);
}
Looking to solve this error that I'm getting when trying to display some data to the view. I'm working with v5.7 and I have a feeling it might be something with the index method in my controller, I could be very wrong. If there is any more info that is needed please let me know.

Post table
Blog Cats table
The belongsTo function accepts a second argument for the name of the foreign key in your posts table, if you do not provide it the framework will try to guess what is the foreign key column name giving the name of the function as pattern, in your case category(), so the framework is searching for category_id, however, your foreign key column name is blog_category_id.
public function category()
{
return $this->belongsTo(BlogCategory::class, 'blog_category_id');
}
You should call the category relationship in the index of your controller, if this view is related to the index method!
public function index()
{
$categories = BlogCategory::with(['posts' => function ($query) {
$query->published();
}])->orderBy('title', 'asc')->get();
$posts = Post::with('author')
->category()
->latestFirst()
->published()
// ->filter(request()->only(['term','year','month']))
->simplePaginate($this->limit);
return view('pages.frontend.blog.index', compact('posts', 'categories'));
}
I am trying to get the posts that belong to each category, i had this working before but i can't seem to find what i have done wrong here.
I have a Post Table and a Categories Table
ROUTE
Route::get('articles/category/{id}', ['as' => 'post.category', 'uses' => 'ArticlesController#getPostCategory']);
CONTROLLER
public function getPostCategory($id)
{
$postCategories = PostCategory::with('posts')
->where('post_category_id', '=', $id)
->first();
$categories = PostCategory::all();
// return view
return view('categories.categoriesposts')->with('postCategories', $postCategories)->with('categories', $categories);
}
VIEW
#foreach($postCategories->posts as $post)
<div class="well">
<div class="media">
<a class="pull-left" href="#">
<img class="media-object" src="http://placekitten.com/150/150">

// Category belongs to more than 1 post
public function posts()

}

I can't see what i am doing wrong every time I go to a category it shows
Trying to get property of non-object
Any help will be much appreciated thanks
replace your lines:
$postCategories = PostCategory::with('posts')
->where('post_category_id', '=', $id)
->first();
with:
$postCategories = PostCategory::find($id)->posts;
Change your line in your PostCategoryModel to:
return $this->hasMany('App\Post', 'post_category_id','post_category_id');
I do not know exactly how this works, so that's why I'm asking. I'm still working on a Bulletin Board System and now I want under each category, a subcategory.
For example:
I have done this using the following thread on LaraCasts:
https://laracasts.com/discuss/channels/eloquent/eloquent-getting-subcategories-from-the-categories
Now my IndexController looks like this:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Thread;
use App\Chat;
use App\Category;
class IndexController extends Controller
{
/**
* Show the application dashboard.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
$threads = Thread::all()->toArray();
$chats = Chat::orderBy('id', 'DESC')->take(50)->with('author')->get();
$categories = Category::with('sub_category')->get();
return view('index', compact('threads','chats','categories'));
}
}
This is my Category Model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Category extends Model
{
public function sub_category()
{
return $this->belongsTo(self::class, 'parent_id', 'id');
}
public function parent_category()
{
return $this->hasMany(self::class, 'id', 'parent_id');
}
}
My view (index.blade.php):
#foreach($categories as $category)
<div class="col-md-8">
<div class="panel panel-primary">
<div class="panel-heading"><i class="fa fa-angle-right" aria-hidden="true"></i> {{ $category->caption }}</div>
<div class="panel-body">
#foreach($category->sub_category as $sub_category)
<div class="row forum-row">
<div class="col-xs-12 col-md-8 col-sm-8">
<div class="hidden-xs visible-sm visible-lg visible-md pull-left forum-icon-read">
<i class="fa fa-comment"></i>
</div>
{{ $sub_category->caption }}<br>
<small>{{ $sub_category->desc }}</small>
</div>
<div class="col-xs-12 col-md-4 col-sm-4 forum-latest-container">
<p class="forum-data cutoff">Test</p>
<small>
door <a class="Donateur" href="/user-Sygun">Sygun</a>
<p class="forum-data">
2 minuten geleden </p>
</small>
</div>
</div>
#endforeach
</div>
</div>
</div>
#endforeach
I also have two database tables:
Sub_categories (id, caption, parent_id, min_rank, desc)
Categories (id, caption, min_rank, desc)
The error message I get:
Invalid argument supplied for foreach()
Can you tell me what is the right way to achieve this?
Create two model named Category and SubCategory.
In Category model
public function subcategories()
{
return $this->hasMany('App\SubCategory', 'parent_id');
}
In SubCategory model
public function parent_category()
{
return $this->belongsTo('App\Category', 'parent_id');
}
Then in your controller query it like:
$categories = Category::with('subcategories')->get();
And hopefully your foreach will work.
Category model
public function subcategories(){
return $this->hasMany('SubCategory', 'parent_id');
}
On view
#foreach($categories as $category)
#foreach($category->subcategories as $subcategory)
{{$subcategory->caption}}
#endforeach
#endforeach
And make sure you create SubCategory model.
