How to get all the array in relations model. It supposed to be 3 records in relation service, I can fetch all the services of doctor if per one record, but if I will display all the doctor with services, the services per doctor displaying only one.
In my controller
$doctors = User::with('reviews', 'services')->role('Doctor')->where('clinic_id', $id)->get();
User Model
public function services()
{
return $this->belongsTo(Service::class, 'id', 'doctor_id');
}
This is the structure of service table
I've tried hasMany but relation service is empty
You have to change your relation in User model to hasMany as Doctor has many services
per your table structure.
public function services()
{
return $this->hasMany(Service::class, 'doctor_id', 'id');
}
and in Service model use belongsTo

So I have this model Order which has one to many relation with ProductOrder model. And also Product model which has the same one to many relation with ProductOrder model. I can get the PorductOrder data with Product or with Order. Like this:
Order::with('product_orders')->get();
Now this is returning my orders with the associated ProductOrder data. How can I include the Products of each ProductOrder data in this collection?
Make changes of function name, field name, model name as per you requirements
Step 1:
In you ProductOrder Model use this function:
public function products()
{
return $this->hasOne('App\Product', 'id', 'product_id');
}
Step 2:
After this in you query you can use as:
Order::with('product_orders.products')->get();
It sounds like ProductOrder is just a joining table/model, is that right? If that is the case, you should change to a ManyToMany relationship to of the Products model to
public function orders()
{
return $this->belongsToMany('App\Orders', 'product_order');
}
and the Orders to
public function products()
{
return $this->belongsToMany('App\Products', 'product_order');
}
Then you can access like
Order::find(1)->products()->get();
I am using the User model and want to reference other users on a One to Many relationship.
With two models, this would be done by a Many to Many but this attempt at it is obviously wrong:
public function relatedUsers()
{
return $this->belongsToMany(User::class, 'related_user', 'user_id', 'user_id');
}
Is there a better way I can achieve my goal? I don't need an inverse method.
You can use hasMany() or belongsTo() (according to your need) relation for same model relationship
Define hasMany relationship in User model:
public function relatedUsers() {
return $this->hasMany('User','user_id');
}
Example:
Consider you have one User object
$user = User::where('id',$id)->first();
If you want to access related records
$related_users = $user->relatedUsers; // this will return all related users for particular object
I have 3 tables users, companies and pivot table with user_id, company_id.
I can't get users, which belongs to my company inside User model.
Tried like
belongsToMany('App\User','companies_users','company_id','user_id' );
but I get relation with wrong users.
Since you are having a belongsToMany relationship between the User and Company, the User belongs to more than one Company. To get users of the companies of a particular User will not be straight forward. If you are sure that is exactly what you want, then do this:
//inside the User model
public function companies()
{
return $this->belongsToMany('Company');
}
//inside the User model
public function companiesusers()
{
$users= new Illuminate\Database\Eloquent\Collection;
foreach($this->companies as $company)
{
$users = $users->merge($company->users->get());
}
return $users->unique();
}
//inside the Company model
public function users()
{
return $this->belongsToMany('User');
}
Then you can get a user's companiesusers like so:
User::first()->companiesusers();
I am busy building a online ordering system, but now I am stuck with this one table relationship.
I want the User to be able to create many orders, and the order will have many products.
I have looked at many-to-many relationships, however it does not include a third table.
The basic many-to-many relationship releases by pivot table and declares in laravel like belongsToMany
In your situation you can use hasManyThgough relationship to access all products which are connected with user through orders
User.php
public function orders() {
return $this->hasMany('App\Order');
}
public function products() {
return $this->hasManyThrough('App\Product', 'App\Order');
}
Order.php
public function products() {
return $this->hasMany('App\Product');
}
Link to laravel relationship hasManyThrough documentation
I have three models with Many to Many relationships: User, Activity, Product.
The tables look like id, name. And in the each model there are functions, for example, in User model:
public function activities()
{
return $this->belongsToMany('Activity');
}
public function products()
{
return $this->belongsToMany('Product');
}
The pivot table User_activity_product is:
id, user_id, activity_id, product_id. The goal is to get data like: User->activity->products.
Is it possible to organize such relations in this way? And how to update this pivot table?
First I suggest you rename the pivot table to activity_product_user so it complies with Eloquent naming convention what makes the life easier (and my example will use that name).
You need to define the relations like this:
// User model
public function activities()
{
return $this->belongsToMany('Activity', 'activity_product_user');
}
public function products()
{
return $this->belongsToMany('Product', 'activity_product_user');
}
Then you can fetch related models:
$user->activities; // collection of Activity models
$user->activities->find($id); // Activity model fetched from the collection
$user->activities()->find($id); // Activity model fetched from the db
$user->activities->find($id)->products; // collection of Product models related to given Activity
// but not necessarily related in any way to the User
$user->activities->find($id)->products()->wherePivot('user_id', $user->id)->get();
// collection of Product models related to both Activity and User
You can simplify working with such relation by setting up custom Pivot model, helper relation for the last line etc.
For attaching the easiest way should be passing the 3rd key as a parameter like this:
$user->activities()->attach($activityIdOrModel, ['product_id' => $productId]);
So it requires some additional code to make it perfect, but it's feasible.
The solution was found with some changes.
In the models relationships look like:
// User model
public function activities()
{
return $this->belongsToMany('Activity', 'user_activity_product', 'user_id', 'activity_id')->withPivot('product_id');
}
public function products()
{
return $this->belongsToMany('Product', 'user_activity_product', 'user_id', 'product_id')->withPivot('activity_id');
}
To update pivot table:
$user->products()->save($product, array('activity_id' => $activity->id));
- where product and activity ids I get from Input.
And, for example, to check if "user -> some activity -> some product is already exists":
if ($company->activities->find($activity_id)->products()->where('product_id', '=', $product_id)->wherePivot('company_id', $company_id)->get()->count() > 0) {
// code...
}
I think it needs improvements but it works for me now.
