Laravel 7 - Mastering the Art of Passing Data to Views

I am currently working with two tables, Companies and Projects. In this setup, a company has many projects while a project belongs to a specific 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');
}

On my index.blade.php file, I have a list of companies that are clickable. When a user clicks on a company, they are redirected to show.blade.php where the company's name and its associated projects are displayed. Here is an example:

<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>

I encountered an error indicating that $project was an undefined variable. To resolve this issue, I made changes in the show() function of CompaniesController.php:

public function show(Company $company)
{
    $company = Company::find($company->id);
    $projects = Company::find(1)->projects;

    return view('companies.show', ['company' => $company, 'projects' => $projects]);
}

In order to access the variable in show.blade.php, I used the following approach:

    <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>

However, another error popped up stating that Class 'App/Project' not found when accessing show.blade.php. It seems like passing company projects to the view is posing a challenge for me. Any assistance on resolving this issue would be highly appreciated. Below are my defined 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

It would be quite the laugh if I turn out to be correct....

When defining relationships in your models, remember to use App\Project instead of App/Project. The same goes for Company - replace "/" with "\".

Answer №2

Ensure that the Project class is properly namespaced.

  1. Confirm that the file name is Project.php
  2. Verify that the namespace declaration inside Project.php is accurate: namespace App;
  3. Check that the class name inside Project.php is 'Project':
    class Project extends Model { ...
  4. Make sure to import it in the controller: use App\Project

Once you have completed all these steps, you should no longer see the error:

Class 'App/Project' not found

You have successfully passed a variable in the view, but for more examples and methods on passing variables, refer to: https://laravel.com/docs/7.x/views

I hope this information proves useful for you.

Answer №3

Utilizing model binding is already in place for you. Within your show method, there is no need to search for the data. Simply return what you require

public function display(Company $company)
{
    return view('companies.show', ['company' => $company];
}

Within your view, you can proceed with:

@foreach($company->projects as $project)
...
@endforeach
