Laravel 5.5 BelongsToMany returns empty - php

I'm trying to use a belongsToMany relation, i never had any problems with it but for some reason it returns empty.
I've set up my relation in the Store model like this:
public function images()
{
return $this->belongsToMany('App\Images', 'images_stores', 'image_id', 'store_id');
}
When i test the relationship it returns no error just a empty collection although it's not. This is the way i access the data:
public function edit($id)
{
$store = Store::find($id);
dd($store->images);
return view('admin.pages.store.edit', compact('store'));
}
But it would just return a empty collection, i hope someone could help me out with this. These are my migration file's but i don't think the problem is inside the migration files.
Schema::create('images', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('path');
$table->timestamps();
});
// pivot table
Schema::create('images_stores', function (Blueprint $table) {
$table->increments('id');
$table->integer('image_id')->unsigned()->nullable();
$table->foreign('image_id')->references('id')->on('images')->onDelete('cascade');
$table->integer('store_id')->unsigned()->nullable();
$table->foreign('store_id')->references('id')->on('stores')->onDelete('cascade');
$table->timestamps();
});
// store table
Schema::create('stores', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('location');
$table->string('email');
$table->timestamps();
});
Thanks guys.

I think the ids are inverted. Try this:
public function images()
{
return $this->belongsToMany('App\Images', 'images_stores', 'store_id', 'image_id');
}

Laravel 8 relationship of three models which belongs to Parent model

Hello everyone I'm currently working on a laravel project where I have a parent table that has the id's of three tables referenced to it. These table migrations also have their models respectively. Here are the table migrations files respectively:
create_products_table.php
Schema::create('products', function (Blueprint $table) {
$table->id();
$table->string('product_id', 10);
$table->string('product_name');
$table->string('image');
$table->string('images');
$table->string('product_description');
$table->bigInteger('size_id')->unsigned();
$table->string('color');
$table->string('product_quantity');
$table->string('old_price');
$table->string('discount');
$table->string('product_price');
$table->bigInteger('user_id')->unsigned()->nullable();
$table->bigInteger('category_id')->unsigned();
$table->bigInteger('gender_id')->unsigned();
$table->timestamps();
$table->foreign('size_id')->references('id')->on('sizes')->onDelete('cascade');
$table->foreign('category_id')->references('id')->on('categories')->onDelete('cascade');
$table->foreign('gender_id')->references('id')->on('genders')->onDelete('cascade');
});
create_genders_table.php
Schema::create('genders', function (Blueprint $table) {
$table->id();
$table->string('gender_class');
$table->timestamps();
});
create_categories_table.php
Schema::create('categories', function (Blueprint $table) {
$table->id();
$table->string('cat_name');
$table->timestamps();
});
create_sizes_table.php
Schema::create('sizes', function (Blueprint $table) {
$table->id();
$table->string('sizes');
$table->timestamps();
});
Also this is how I defined the relationships on their models respectively
Product.php
public function category()
{
return $this->belongsTo(Category::class);
}
public function gender()
{
return $this->belongsTo(Gender::class);
}
public function size()
{
return $this->belongsTo(Size::class);
}
Category.php
public function products()
{
return $this->hasMany(Product::class);
}
Gender.php
public function products()
{
return $this->hasMany(Product::class);
}
Size.php
public function products()
{
return $this->hasMany(Product::class);
}
I'm actually a laravel beginner and I studied eloquent model relationships at laravel.com so what I did was just based on my understanding of one to many relationships. When I check all my request with dd($request), category_id, gender_id, size_id all show null and I believe it's because I didn't define the relationship properly. Now this is where I seriously need your assistance.
So please my experienced developers I seriously need your help I'll really be grateful if I get your replies today. Thanks in advance.
=>Everything is right, just make changes in the products migration add this code.
$table->foreign('size_id')->references('id')->on('products')->onDelete('cascade');
$table->foreign('category_id')->references('id')->on('products')->onDelete('cascade');
$table->foreign('gender_id')->references('id')->on('products')->onDelete('cascade');
=>and migrate table

one to many And one to many relationship laravel

This is projects migrate
Schema::create('projects', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('start_date');
$table->string('end_date');
$table->string('con');
$table->timestamps();
});
and this is timesheets migrate
Schema::create('timesheets', function (Blueprint $table) {
$table->increments('id');
$table->string('user_id');
$table->string('project_id');
$table->string('day');
$table->string('month');
$table->string('year');
$table->string('jalali');
$table->string('timesheet_h');
$table->string('timesheet_m');
$table->timestamps();
});
and this users migrate
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('mobile');
$table->string('salary_base');
$table->string('salary_base_h');
$table->string('start_contract');
$table->string('end_contract');
$table->string('start_insurance');
$table->string('end_insurance')->nullable();
$table->string('first_salary');
$table->string('date_birth');
$table->string('melli_code');
$table->string('s_number');
$table->string('nda');
$table->string('work_rules');
$table->string('end_work')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
This my project model
public function timesheets()
{
return $this->hasMany(timesheet::class,'project_id');
}
This my timesheet model :
public function projects()
{
return $this->belongsTo(project::class,'project_id');
}
public function users()
{
return $this->belongsTo(User::class,'user_id','id');
}
and This my User model
public function project_peoples()
{
return $this->hasMany('App\project_people');
}
public function timesheets()
{
return $this->belongsTo(timesheet::class);
}
public function projects()
{
return $this->belongsTo(project::class);
}
Now I return my query from projects
public function allProject()
{
$projects=project::with(['timesheets','users'])->get();
return $projects;
}
This is ok but user_id Users in timesheets.user_id And I can not get it out timesheets and get it
This controller return project and timesheet by project_id in timesheet but user_id in timesheet I do not know how to get this into the system
Use dot syntax to load nested relationships:
project::with('timesheets.users')->get();

Getting distant belongsToMany through belongsToMany

I'm trying to grab a distant relationship and it isn't working. I've tried doing a hasManyThrough but that doesn't appear to work for belongsToMany relationships. It was throwing a query error.
Here are my migrations:
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
Schema::create('roles', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->timestamps();
});
Schema::create('role_user', function (Blueprint $table) {
$table->integer('role_id');
$table->integer('user_id');
});
Schema::create('permissions', function (Blueprint $table) {
$table->increments('id');
$table->string('group');
$table->string('name');
$table->timestamps();
});
Schema::create('permission_role', function (Blueprint $table) {
$table->integer('permission_id');
$table->integer('role_id');
});
Here are my models:
class User extends AuthUser
{
//
public function roles()
{
return $this->belongsToMany('App\Role');
}
}
class Role extends Model
{
//
public function permissions()
{
return $this->belongsToMany('App\Permission');
}
}
What I'm trying to do:
$user = App\User::find(1);
Log::info($user->roles->permissions);
This gives me a Property [permissions] does not exist on this collection instance. error.
How do I grab the users permissions through their roles?
EDIT:
I've come up with this ugly solution to what I'm trying to do:
if (auth()->check()) {
if (auth()->user()->roles->contains('name', 'Admin')) {
Gate::before(function () {
return true;
});
}
else {
$permissions = [];
foreach (auth()->user()->roles as $role) {
$permissions = array_merge($permissions, $role->permissions->pluck('name')->all());
}
foreach (array_unique($permissions) as $permission) {
Gate::define($permission, function () {
return true;
});
}
}
}
How can I improve this?
You should eager load those relationships like this:
$user = User::with(['roles', 'roles.permissions'])->where('id', 1)->first();
This will give you an array of roles, and each role with their respective permissions.
Permission::whereHas('role', function($query) use ($user_id) {
return $query->whereHas('user_id', $user_id);
});
The idea in the above query is that when you want the many to many of a distant relationship, you work backwards.
change $user=App\USER->find(1);
to this
$user= App\User::find(1);
try this will work for you
you have not set foreign key in migration
$table->foreign('role_id)->references('id')->on('roles');
Same define for users
It gave you Property [permissions] does not exist on this collection instance. error because: $user->roles returns a collection of roles while permissions in your model Role is for a single model only ..
Basically you have to foreach($user->roles as $role) before you can use $role->permissions
but here's a sample where you don't have to foreach to get a permission depending on a role ..
auth()->user()->roles->where('name','=','Administrator')->permissions;
and that would be returning an array/collection of permissions of an administrator ..

Laravel Many to Many Relationship Users on Shift

I'm trying to get the users that are on today's shift. I have a many to many relationship between the User and Shift model with a pivot table called user_shifts.
My User model:
/**
* Get the users shifts
*/
public function shift()
{
return $this->belongsToMany('App\Shift', 'user_shifts', 'user_id', 'shift_id');
}
My Shift model
/**
* The shift can have many users
*/
public function users()
{
return $this->belongsToMany('App\User', 'user_shifts', 'shift_id', 'user_id')->withPivot('start_time', 'end_time');;
}
In my controller I thought I could do something like:
$shift = Shift::all()->where('date', date('Y-m-d'));
$users = User::all()->where('shift_id', $shift);
return $users;
But that is returning null. Any help would be appreciated!
If it matters my db schema is:
Schema::create('shifts', function (Blueprint $table) {
$table->increments('id');
$table->date('date');
$table->boolean('weekend');
});
Schema::create('user_shifts', function (Blueprint $table) {
$table->increments('id');
$table->integer('shift_id');
$table->integer('user_id');
$table->time('start_time');
$table->time('end_time');
});
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('fname');
$table->string('lname');
$table->string('email')->unique();
$table->string('password', 60);
$table->rememberToken();
$table->timestamps();
});

How to query pivot table using Eloquent in Laravel 5

I have a many-to-many relationship between my client and tag tables. A client can have many tags, and each tag can be related to multiple clients.
On the client show view, I'm trying to display the client info plus all tags associated to this client.
How do I change the query below to retrieve the client rows with all its related tags?
public function show($id)
{
$client = Client::findOrFail($id);
return view('clients.show')->with(['client' => $client]);
}
Client model
public function clienttag()
{
return $this->belongsToMany('App\Clienttag');
}
Clienttag model
public function client()
{
return $this->belongsToMany('App\Client');
}
Client_clientags table migration
public function up()
{
Schema::create('client_clienttag', function(Blueprint $table)
{
$table->integer('client_id')->unsigned();
$table->foreign('client_id')->references('id')->on('clients')->onDelete('cascade');
$table->integer('clienttag_id')->unsigned();
$table->foreign('clienttag_id')->references('id')->on('clienttags')->onDelete('cascade');
$table->timestamps();
});
}
Clients table migration
public function up()
{
Schema::create('clients', function(Blueprint $table)
{
$table->increments('id');
$table->string('first_name');
$table->string('last_name');
$table->rememberToken();
$table->timestamps();
});
}
Clienttags table migration
public function up()
{
Schema::create('clienttags', function(Blueprint $table)
{
$table->increments('id');
$table->string('tag');
$table->text('description');
$table->rememberToken();
$table->timestamps();
});
}
You can use "Eager Loading" methods like the following
public function show($id)
{
$client = Client::with('clienttag')->findOrFail($id);
return view('clients.show')->with(['client' => $client]);
}
Check documentation at http://laravel.com/docs/5.1/eloquent-relationships#eager-loading
Then at your view you can print your tags
#foreach ($client->clienttag as $tag)
{!! $tag->tagname!!} (or whatever your field in clienttags table name is)
#endforeach
