I am able to create and even delete a polymorphic row from my app, but I can not for the life of me able to figure out how to query the relationship so I can update the row. My models and controller methods are below--all work except for public function updateManifest($id). I didn't include all the update code I've been trying over the past day and a half because it would be too much and not really relevant, but I can tell you that I can only get as deep as the Workorder model, I can't seem to query anything related through the poly relationship so I can query all the manifest objects. Thank you.
Workorder.php

public function manifestable(){
return $this->morphTo();
}
}

I'm using laravel 9.11
I have a stock table containing items and each item is related to a specific place,
table snapshot
I have another form to make changes of values and I want to loop throw all places that exist in stock table but withouh making duplicate record.
snapshot of the error
showing the error
I do have all record of stock places and made a loop throw it but I want a way to avoid duplicating the records.
Blade code
<div class="mb-3">
<label for="place_name" class="block mb-2 mt-2 text-sm font-medium text-gray-900 dark:text-gray-400">

Stock Model
class Stock extends Model
{
use HasFactory;
protected $fillable = ['current_stock', 'asset_id', 'place_id', 'quantity_id'];
public function assets() {
return $this->belongsTo(Asset::class, 'asset_id');
}
public function places() {
return $this->belongsTo(Place::class, 'place_id');
}
// Relation to know quantity of assets
public function quantity() {

Place Model
class Place extends Model

use HasFactory;

public function stocks() {

I think you can eager load Stock::with('places')->get() and later map your collection
with something like.
$stocksCollection = Stock::with('places')->get();
$collection = $stocksCollection->map(function ($array) {
return collect($array)->unique('place_id')->all();
});

The current output is:

Thanks for reading! :D
If is complaining that it can't find a variable called $navContent.
I can't see you passing it to either of the views you are calling from your index() functions.
return view('navManagement', compact('navs'));
return view('pageManagement', compact('pages'));
You would need to set that varaible and pass it to the view
// Get the nav content however you want, this is just a crude example
$navContent = $this->getMyNavContent();
return view('navManagement', [
'navs' => $navs,
'navContent' => $navContent
]);
I'm guessing you want to find a way to embed the dynamic nav without having to add the navContent every time you render a view, as that's what the other answer is suggesting. You could achieve this using a middleware, say dynamicNav and registering your routes under that middleware group.
In that middleware you can do all the logic of fetching the nav content and then use something like merge, as shown here:
$request->merge(['dynamicNav' => $navContent]);
This way your middleware will add the data to every request which goes through it, although I wouldn't recommend this solution.
What I would do is cache the nav content and retrieve in the view using the cache() helper, then override the save() method of the model to also update the cache when the DB is updated (to avoid duplicate code, you could create a trait for the fetching of the nav). Example:
// in your model
public function save(array $options = [])
{
Cache::put('nav-content', getNavContent());
parent::save();
}
I have two tables with a many to many relation (Project and Center, the pivot table is ProjectCenter).
These are my models:
Project:
class Project extends Model {
public function centers()
{
return $this->belongsToMany('App\Models\Center', 'ProjectCenter', 'IDProject', 'IDCenter');
}
public function getCenterListAttribute()
{
return $this->centers->lists('IDCenter')->all();
}
}
Center:
class Center extends Model {
public function projects()
{
return $this->belongsToMany('App\Models\Project', 'ProjectCenter', 'IDCenter', 'IDProject');
}
}
Controller -> edit:
public function edit($id)
{
$project = Project::find($id);
$centerList = Center::lists('Name', 'IDCenter')->toArray();
return view('project/add', array('centerList' => $centerList))->with('project', $project);
}
And the view:
{!! Form::label('centers_list', 'Center*') !!}
{!! Form::select('centers_list[]',
$centerList,
null,
array(
'class' => 'form-control ',
'required' => 'required',
'multiple' => true,
'data-placeholder' =>
'Select a center'
)
) !!}
But I can not select the data already stored previously.
For example: the project 8 (IDProject) has two centers (1 and 2) but the data is not populated in the multiple select:
What am I doing wrong?
You all time get same result $centerList = Center::lists('Name', 'IDCenter')->toArray(); but you must be get product centers using query with model.
$project = Project::with("centers:Name,IDCenter")->find($id);
$centerList = $project->centers->pluck('Name', 'IDCenter')->toArray();
I already solve the problem using a foreach to select the related centers:
<select multiple="multiple" name="centers[]" id="centers" class="form-control select2" required="required" data-placeholder="Select a center">
#if($centerList)
#foreach($centerList as $key => $center)
<option value="{{$key}}" {{ (collect($selectedCenters)->contains($key)) ? "selected='selected'" : '' }} >{{$center}}</option>
#endforeach
#endif
</select>

im still new to laravel, and what did i do wrong that make such an error like that?
I found the answer, i got the reference from here so based on that reference and the basic of x->y->z, we got to check first that x->y have some value in it if yes we got to check whether it's an object or just an array, in my case it was an array so rather doing something like this
{{$project->client->cv_name}}
which is that how to display an object, we should do something like this
{{$project->client['cv_name']}}
and that is how you solve your problem, cheers :D
I have created very basic Model. I have persons table and emails table.
Also I have create a link in the persons/show.blade.php ("Add mail").
My models are
class Person extends Eloquent {
protected $table = 'persons';
public function email()
{
return $this->HasMany('Email');
}
}
and
class Email extends Eloquent {
protected $table = 'emails';
public static $rules = array(
'email'=>'required|unique:emails'
);
public function person()
{
return $this->belongsTo('Person');
}
}
How can I pass the $person->id to the new Controller?
In my show.blade.php for Person I added
{{ HTML::linkRoute('email.adduseremail','Προσθήκη Email',array($person->id))}}
and I added to my EmailController
public function adduseremail($id)
{
return View::make('email.createforuser',['id'=>$id]);
}
public function storeforuser($pid)
{
$validator = Validator::make(Input::all(),Email::$rules);
if ($validator->fails()) {
$messages = $validator->messages();
foreach ($messages->all('<li>:message</li>') as $message)
return Redirect::back()->withInput()->WithErrors($messages);
}
$person = Person::FindorFail($pid);
$email = new Email;
$email->email = Input::get('email');
$email->person()->associate($person);
$email->save();
return Redirect::route('person.index');
}
and my createforuser view is
<p>
{{Form::open(['route'=>'email.storeforuser'])}}
<div>
{{Form::label('email', 'Email:')}}
{{Form::input('text', 'email')}}
{{$errors->first('email')}}
</div>
</br>
<div>
{{Form::submit('Submit')}}
</div>
{{Form::close()}}
<p>
I keep getting Trying to get property of non-object (View: /var/www/laravel/app/views/email/show.blade.php)
Is there any example using Form and Models for inserting new objects to the database for 'belongsTo' Relationship? I couldn't find anything complete , just partial examples.
I generally use laravel sessions or laravel cache to tempererally save an id that i need to use later like:
Session::set('personId',$person->id);
Session::get('personId');
The same is for cache except cache will only last for the current request session is persistent for the session
Hope that helps
I am no sure if I 'm supposed to answer my own question but finally I found a solution.
I set two new routes
Route::post('email/adduseremail/{pid}', array('uses'=>'EmailController#adduseremail','as' => 'email.adduseremail'));
Route::post('email/storeforuser/{pid}', array('uses' =>'EmailController#storeforuser','as' => 'email.storeforuser'));
and created the corresponding methods in my Controller
public function adduseremail($id)
{
$pname = Person::Find($id)->name;
$psurname = Person::Find($id)->surname;
return View::make('email.createforuser',array('id'=>$id,'name'=>$pname, 'surname'=>$psurname));
}
and
public function storeforuser($pid)
{
$validator = Validator::make(Input::all(),Email::$rules);
if ($validator->fails())
{
$messages = $validator->messages();
foreach ($messages->all('<li>:message</li>') as $message)
return Redirect::back()->withInput()->WithErrors($messages);
}
$person = Person::FindorFail($pid);
$email = new Email;
$email->email = Input::get('email');
$email->person()->associate($person);
$email->save();
return Redirect::route('person.show',array($person->id));
}
then on my view blade pages I can pass the parameters from View to Form and so on
person.show.blade.php
{{Form::Open(array('route' => array('email.adduseremail', $person->id),'method' => 'POST','style'=>'display:inline;'))}}
{{Form::submit('Add Email')}}
{{Form::close()}}
and
email.createforuser.blade.php
{{Form::open(array('route'=>array('email.storeforuser',$id),'method' => 'POST','style'=>'display:inline;'))}}
{{Form::label('email', 'Email:')}}
{{Form::input('text', 'email')}}
{{Form::submit('Submit')}}
Hope it helps others also
