LARAVEL Ultimate Laravel 3

Question 1

Which Laravel command is used to run only the most recently created migration file?

Accepted Answer

php artisan migrate --step=1

Answer

`php artisan migrate --step=1` runs exactly one pending migration, which is the most recently created one.

Question 2

In Laravel Broadcasting, what interface must a model implement to broadcast its events on a private channel scoped to that model?

Accepted Answer

Illuminate\Contracts\Broadcasting\HasBroadcastChannel

Answer

Implementing `HasBroadcastChannel` and defining `broadcastChannel()` allows Eloquent models to expose a named private channel.

Question 3

Which Eloquent relationship method would you use to define a 'belongs to many' with an intermediate pivot table?

Accepted Answer

belongsToMany()

Answer

`belongsToMany()` defines a many-to-many relationship and expects a pivot table named by combining the two model names alphabetically.

Question 4

What is the default behavior of Laravel's `Route::resource()` when the model cannot be found during route model binding?

Accepted Answer

It returns a 404 HTTP response

Answer

By default, route model binding automatically returns a 404 response when the model is not found in the database.

Question 5

Which method allows you to add a global scope to an Eloquent model so it applies to every query on that model?

Accepted Answer

boot() with addGlobalScope()

Answer

Defining `addGlobalScope()` inside the model's `boot()` method registers a scope class or closure that applies to all queries.
