Laravel - Setting a default route prefix

Question

I'd like to set a default route prefix for all my routes based on the users company e.g.

Route::group(['prefix' => '/{company}'], function() {
    Route::get('/', 'CompaniesController@index')->name('company.index');

});

Is there some way i can set this value through middleware etc so i don't have to do something like this on every method and the user only has access to their own company.

public function index(Company $company)
    {
        if(auth()->user()->company == $company) {
            return $company;
        }
        abort(404);
    }

Using Laravel 6.x

You don't need any custom middleware for this you can achieve this with Policies & the build-in can middleware of laravel.

In your case it will be something like the following:

// app/Policies/CompanyPolicy.php
class PostPolicy
{
    public function view(User $user, Company $company)
    {
        return $user->company->getKey() === $company->getKey();
    }
}


// web.php
Route::group(['prefix' => '/{company}'], function() {
    Route::get('/', 'CompaniesController@index')->name('company.index');

})->middleware('can:view,company');


// Controller
public function index(Company $company)
{

    return 'magic';
}

For more information about this you can watch the following documentation:
