Many-to-many: middle table with time stamp

Timestamps are not automatically populated when in many-to-many associations, such as role_user in the middle of users and roles tables.

In this model you can define relationships like this:

class User extends Model{ public function roles() { return $this->belongsToMany(Role::class); }}

Then when you want to add a role to a user, you can use it like this:

$roleID = 1;$user->roles()->attach($roleID);

By default, this intermediate table does not contain timestamps. And Laravel does not try to auto-populate created_at/updated_at

But if you want to save timestamps automatically, you need to add created_at/updated_at to the migration file, and then add->withTimestamps() to the model associations;

public function roles(){ return $this->BelongsToMany(Role::class)->withTimestamps();} The above is "How to define timestamped intermediate tables in Laravel many-to-many relations" All the contents of this article, thank you for reading!
