I'm still learning Laravel and I can't find the solution for this problem.
I need to get invoices(with expenses) that are related to specific Partner Type.
I tried this:
$p = Project::with(['invoices.partner.partnerType' => function($query){
$query->where('partnerTypeName', 'Lieferant');
}, 'expenses'
])->where('id', $id)
->first();
I want to select invoices for Lieferant, but I get all invoices for one project.
Project Model:
public function invoices()
{
return $this->hasMany('App\Invoice');
}
Invoice Model
public function expenses()
{
return $this->hasMany('App\Expense');
}
public function partner()
{
return $this->belongsTo('App\Partner');
}
Partner Model
public function partnerType()
{
return $this->belongsTo('App\PartnerType');
}
Edit: PartnerType Model
public function partners()
{
return $this->hasMany('App\Partner');
}
Edit 2: Database
Partner(partnerID, name, partnerTypeId)
PartnerType(partnerTypeId, partnerTypeName)
Project(projectID, name)
Invoice(invoiceID, name, projectID, partnerID)
Expenses(expenseID, invoiceID)
If your models look like that.
Should be like :
$p = Project::with(['invoices' => function($query){
$query->where('partnerTypeName', 'Lieferant')
->with(['expenses','partner' => function($q){
$q->with('partnerType');
}]);
}])->where('id', $id)
->first();
return dd($p);
The solution to your problem is to update your query like this:
$p = Project::with(['invoices' => function($query){
$query->with('expenses')->whereHas('partner.partnerType', function($q){
$q->where('partnerTypeName', 'Lieferant');
});
}])
->where('id', $id)
->first();
But a cleaner solution would be using a scope for your problem.
In your Invoice model.
// Invoice.php
public function scopeByPartnerType($query, $partnerType)
{
$query->whereHas('partner.partnerType', function($q) use ($partnerType) {
$q->where('partnerTypeName', $partnerType);
});
}
And then in your Project model, add another relation that will just get Invoices with a particular partner type.
// Project.php
public function lieferantInvoices()
{
return $this->hasMany('App\Invoices')->byPartnerType('Lieferant');
}
Now you can do just this:
$project->find($id)->load('lieferantInvoices');

I have implemented eloquent relationship in my code but Laravel unable to read the function that I created to map the eloquent relationship in the model.
User Model
public function products(){
return $this->hasMany(Product::class,'userid');
}
Product Model
public function users(){
return $this->belongsTo(User::class);
}
Product Controller
$products = Product::with('Users')->Users()->where('users.isActive',1)->get();
return view('product',compact('products'));
I keep getting error from the product controller, I also attached the error that I current encountered as below.
How can I get all the product and user data with the where condition such as "Users.isActive = 1".
Thanks.
You can use whereHas to filter from a relationship.
$products = Product::with('users')
->whereHas('users', function ($query) {
$query->where('isActive', 1);
})
->get();
Also it is generally a good idea to use singular noun for belongsTo relationship because it returns an object, not a collection.
public function user() {
return $this->belongsTo(User::class);
}
$products = Product::with('user')
->whereHas('user', function ($query) {
$query->where('isActive', 1);
})
->get();
EDIT
If you want to retrieve users with products you should query with User model.
$users = User::with('products')
->where('isActive', 1)
->get();
Then you can retrieve both users and products by
foreach($users as $user) {
$user->products;
// or
foreach($users->products as $product) {
$product;
}
}
You can use whereHas() method for this purpose. Here is the doc
$products = Product::with('users')->whereHas('users', function (Illuminate\Database\Eloquent\Builder $query) {
$query->where('isActive', 1);
})->get();
$users = $products->pluck('users');
return view('product',compact('products'));
You have a typo after the with, is users instead of Users and you're redundant about the Query Builder, remove the ->Users():
Before:
$products = Product::with('Users')->Users()->where('users.isActive',1)->get();
return view('product',compact('products'));
After:
$products = Product::with('users')->where('users.isActive',1)->get();
return view('product',compact('products'));
Fix that and all should work.
In my laravel-application I want to display a list of all users/candidates. So far I have this, which basically works fine:
public function candidates()
{
$users = User::whereHas(
'roles',
function ($q) {
$q->where('slug', 'candidates');
}
)->get();
return response(['success' => true, "users" => $users], 200);
}
Now, I actually want to display users/candidates who have taken an education. I have a Model called UserEducation but I don't really know to include it to get the data out I want.
can someone help me out?
EDIT
In my User model, I have this relation:
public function educations()
{
return $this->hasMany('App\Models\UserEducation');
}
you can use has:
$users = User::has('UserEducation')->whereHas(
'roles',
function ($q) {
$q->where('slug', 'candidates');
}
)->get();
You can try create relationship with User and UserEducation models and then get data.
https://laravel.com/docs/7.x/eloquent-relationships
I need to query and check if the relationship column is the same in my main table column.
example codes:
not working
User::with('product', => function($q) {
$q->whereRaw('users.company_id',' product.company_id');
})->get();
not working
User::with('product', => function($q) {
$q->whereRaw('users.company_id = product.company_id');
})->get();
not working
User::with('product')->whereColumn('users.company_id', 'product.company_id')->get();
but it's not working..
any idea how to do it?
My Models
User Model
public function product()
{
return $this->belongsTo(Product::class, 'product_id');
}
Product Model
public function users()
{
return $this->hasMany(User::class, 'product_id');
}
Please try again:
User->with(['product' => function ($query) {
$query->join('users', 'users.company_id', '=', 'product.company_id');
}])->get();
Try to use DB:raw() then show the table info? like this
I have this DB structure:
classroom_user is Elqouent many-to-many pivot.
User.php:
public function classrooms() {
return $this->belongsToMany(ClassRoom::class, 'classroom_user', 'classroom_id', 'user_id');
}
ClassRoom.php:
public function users()
{
return $this->belongsToMany(User::class, 'classroom_user', 'user_id', 'classroom_id');
}
I have a $user and want to write Eloquent method which gets all users who are in at least one of classrooms the $useralso is in. Something like $user->classrooms->users. But this falls with error Property [users] does not exist on this collection instance.. How can I do this?
I think you can do it like this:
$users = User::whereHas('classrooms', function($query) {
$query->whereHas('users', function($query) {
$query->where('id', auth()->user()->id);
});
})->get();
You could store this as a scope in your User model:
public function scopeClassmatesOf($query, $user)
{
$query->whereHas('classrooms', function($query) use($user) {
$query->whereHas('users', function($query) use($user) {
$query->where('id', $user->id);
});
})
}
And then call it from a controller like:
$user = auth()->user();
$users = User::classmatesOf($user)->get();
Your asking for users of a collection. $user->classrooms is a collection of classrooms.
If you do $user->classrooms->first()->users you will get all the users from the first classroom.
To get all users from all classrooms, you can do something like;
$users = $user->classrooms->map(function ($classroom) {
return $classroom->users;
});
Note that will return duplicate users and authenticated user him self witin the collection. So, you might need to do some filtering to the result.
This worked for me:
public function classmates() {
$self = $this;
$a = User::with('classrooms')->whereHas('classrooms', function ($query) use ($self) {
$query->whereHas('users', function ($query) use ($self) {
$query->where('users.id', $self->id);
});
});
return $a;
}
I have two models, App\Song (belongsTo App\Host) and App\Host (hasMany App\Song).
I have the following query in my Controller:
$songs = Song::whereHas('host', function($query) {
$query->where('skip_threshold', '>', \DB::raw('songs.attempts'))
->where('active', 1);
})
->whereNull('downloaded')
->get();
For reusability I would like to turn into a query scope(s).
I'm quite new to Eloquent so I'm not sure this is the correct way to do this being that its two Models as its not returning any results (where there should be).
Song.php
public function scopeEligable($query)
{
$query->where('skip_threshold', '>', \DB::raw('songs.attempts'));
}
public function scopeActiveHost($query)
{
$query->where('active', 1);
}
public function scopeInDownloadQueue($query)
{
$query->whereNull('downloaded');
}
You should put scopes into Models they belong to. Looking at your initial query scopes scopeEligable and scopeActiveHost belongs to Host model, so you should move them into Host model and then you'll be able to use your query using scopes like this:
$songs = Song::whereHas('host', function($query) {
$query->eligable()->activeHost();
})->inDownloadedQueue()->get();
and as already pointed in comment you should add return to each scope so they could be used as they intended.
EDIT
If you would like to make using it shorter, you could create new relationship in Song model:
public function activeHost()
{
return $this->belongsTo(Host:class)->eligable()->activeHost();
}
so now, you could write:
$songs = Song::whereHas('activeHost')->inDownloadedQueue()->get();
I think you're mistaken about 2 models. I think this should work
Song.php
public function scopeEligable($query, $active) {
return $query->whereHas('host', function($q) {
$q->where('skip_threshold', '>', \DB::raw('songs.attempts'))->where('active', $active);
})
}
public function scopeInDownloadQueue($query)
{
$query->whereNull('downloaded');
}
Usage
$songs = Song::eligable(true)->inDownloadQueue()->get();
