LARAVEL 7 - How to pass variables to views - php

Question

I have two tables, Companies and Projects. A company hasMany projects and a project belongsTo a company.
Company.php model
protected $fillable = [
'id', 'name', 'description'
];
public function projects()
{
return $this->hasMany('App/Project');
}
Project.php model
protected $fillable = [
'name', 'description', 'company_id', 'days'
];
public function company()
{
return $this->belongsTo('App/Company');
}
From my index.blade.php, I list the companies only and I have made them clickable so that when a user clicks on a company listed, they are taken to show.blade.php where the name of the company and the projects that belong to that company are displayed like so.
<div class="jumbotron">
<h1>{{ $company->name }}</h1>
<p class="lead">{{ $company->description }}</p>
</div>
<div class="row">
#foreach($company->projects as $project)
<div class="col-lg-4">
<h2>{{ $project->name }}</h2>
<p class="text-danger">{{ $project->description }}</p>
<p><a class="btn btn-primary" href="/projects/{{ $project->id }}" role="button">View Projects »</a></p>
</div>
#endforeach
</div>
Now am getting an undefined variable $project error. So I decided to declare variable in my show() function of the CompaniesController.php like so
public function show(Company $company)
{
$company = Company::find($company->id);
$projects = Company::find(1)->projects;
return view('companies.show', ['company' => $company, 'projects' => $projects]);
}
And access variable in show.blade.php like so
<div class="jumbotron">
<h1>{{ $company->name }}</h1>
<p class="lead">{{ $company->description }}</p>
</div>
<div class="row">
#foreach($projects as $project)
<div class="col-lg-4">
<h2>{{ $project->name }}</h2>
<p class="text-danger">{{ $project->description }}</p>
<p><a class="btn btn-primary" href="/projects/{{ $project->id }}" role="button">View Projects »</a></p>
</div>
#endforeach
</div>
Now am getting a Class 'App/Project' not found error when I access show.blade.php. I am having a challenge passing company projects to the view. Any help will be appreciated. Here are my routes;
Route::get('/', function () {
return view('welcome');
});
Auth::routes();
Route::get('/home', 'HomeController#index')->name('home');
Route::resource('companies', 'CompaniesController');
Route::resource('projects', 'ProjectsController');

Answer 1

I would be hilarious if I am right....
In your models where defining relations replace App/Project with App\Project. Do the same for Company.... Replace "/" with "\".

Answer 2

You have to namespace Project class properly
Make sure file name is Project.php
Make sure inside Project.php namespace declaration is correct: namespace App;
Make sure class name inside Project.php is 'Project' : class Project extends Model { ...
Make sure you have imported it in controller. use App\Project
After all that done you will not get error:
Class 'App/Project' not found
You have correctly done passing variable in view but have a look here for another examples and methods passing about it:

Hope this helps you

You're already using model binding. In your show method, you do not need to find. just return what you need
public function show(Company $company)
{
return view('companies.show', ['company' => $company];
}
In your view, you can then do:
#foreach($company->projects as $project)
...
#endforeach
