I have two Models User and Owner with many to many relationship
I want to fetch only those users who don't have owner
how can I get using eloquent
i tried
$query = User::whereHas('userOwners', function ( $subquery ){
$subquery->whereNull('owner_id');
})->get();
but not working.
Eloquent has a way to query an absent relationships, it should work like this in your case:
$query = User::doesntHave('userOwners')->get();
User::with('userOwners')
->whereHas('userOwners', function ($query) {
$query->wherehas('owner_id');
})
->where('user_status', 1)->get();
use second where if you want to filter on user
use first where if you want to filter on Owner
I think you should just change your query like:
$query = User::whereHas('userOwners')->get();
Hope this work for you!!!

I'm having trouble to write query in laravel eloquent ORM.
I have a proyect table, where you can assign users, in a many to many relationship
In the view to asign users, I have a selector, but I want to show only the users not already assigned to the proyect and checking also that the user belongs to the company that created the proyect (user.company_id=proyect_id)
In a normal query should me something like this, having $company_id and $proyect_id from the controller.
select * from users u left join proyect_user pu on u.id=pu.user_id and
pu.proyect_id = $proyect_id where u.company_id=$company_i and
proyect_id is null;
The query works, but I would like to use Eloquent. ¿Any idea how to do it?
It depends on how you declared the relationship in the User model. But I would do something like this:
$users = User::whereHas('company', function ($query) use ($companyId) {
$query->where('id', $companyId)
})->whereDoesntHave('proyects', function ($query) use ($proyectId) {
$query->where('id', $proyectId);
})->get();
I want to attach the relationship when getting data from database by model in laravel.
I use these code to do this.
but I know there is better way to do this.
thanks for your helps.
$courses = Cource::orderBy('id' , 'desc')->take($count)->get();
foreach($courses as $cource){
$cource['image'] = $cource->image()->get();
$cource['rate'] = $cource->rate()->get();
}
You might want to use with:
$courses = Cource::orderBy('id' , 'desc')
->take($count)
->with(['image', 'rate'])
->get();
$courses = Cource::orderBy('id' , 'desc')
->take($count)
->with(['image', 'rate'])
->get();
the condition is that use all relationship except morph relationship
Hey guys I have a query that looks like this
$query = Transaction::with(['customer', 'merchant', 'batch'])
->select(sprintf('%s.*', (new Transaction)->table));
I need to filter the transaction based on the iso_id that belons to the current user logged in.
$query = Transaction::with(['customer', 'merchant', 'batch'])
->select(sprintf('%s.*', (new Transaction)->table))
->where('merchant.iso_id', '=', auth()->user()->isIso());
The iso_id I need to compare to, is inside the merchant table
auth()->user()->isIso() returns the correct iso_id if true or sends false if not
So my first try at this was to use where('merchant.iso_id', '=', auth()->user()->isIso())
But that returns that the column does not exist because for some reason, it's not switching from the transaction model to the merchant one.
I am not sure how to use the stuff inside with() as a selector for my where()
Any help would be appreciated!
Try using whereHas to add the constraint:
$query = Transaction::with(['customer', 'batch'])
->whereHas('merchant', function ($q) {
$q->where('iso_id', auth()->user()->isIso());
})
->select(sprintf('%s.*', (new Transaction)->table))
->get();
Im trying to make a query using whereHas with eloquent. The query is like this:
$projects = Project::whereHas('investments', function($q) {
$q->where('status','=','paid');
})
->with('investments')
->get();
Im using Laravel 5.2 using a Postgres driver.
The Project model is:
public function investments()
{
return $this->hasMany('App\Investment');
}
The investments model has:
public function project() {
return $this->belongsTo('App\Project');
}
The projects table has fields id,fields...
The investments table has the fields id,project_id,status,created_at
My issue is that the query runs and returns a collection of the projects which have at least one investment, however the where clause inside the whereHas is ignored, because the resulting collection includes investments with status values different than paid.
Does anyone has any idea of what is going on?
I believe this is what you need
$projects = Project::whereHas('investments', function($q) {
$q->where('status','=','paid');
})->with(['investments' => function($q) {
$q->where('status','=','paid');
}])->get();
whereHas wil check all projects that have paid investments, with will eagerload all those investments.
You're confusing whereHas and with.
The with method will let you load the relationship only if the query returns true.
The whereHas method will let you get only the models which have the relationship which returns true to the query.
So you need to only use with and not mix with with whereHas:
$projects = Project::with(['investments' =>
function($query){ $query->where('status','=','paid'); }])
->get();
Try like this:
$projects = Project::with('investments')->whereHas('investments', function($q) {
$q->where('status','like','paid'); //strings are compared with wildcards.
})
->get();
Change the order. Use with() before the whereHas(). I had a similar problem few weeks ago. Btw, is the only real difference between the problem and the functional example that you made.
I know, we can do this in the controller:
User::with('post')->get();
It will get every user's post from the database, based on users.id.
But the problem is, I want to do this:
User::with(['post' => function($query) {
# Throw users.id here...
}])->get();
How to do that?
You should get the users first, and then load related posts with a separate query and merge them manually.
$users = User::get();
$posts = Post::whereIn('user_id', $users->pluck('id'))->get(); // Get your additional data in this query
$users->each(function ($user) use ($posts)
{
$user->posts = $posts->where('user_id', $user->id);
});
Note: I did not test the code above. It's just an example to show you how to accomplish what you are trying to do.
