Laravel 'many to many' user associates with many posts? - laravel

Question

In PostsController
public function store()
{
$this->validate(request(), [
'title' => 'required',
'body' => 'required'
]);
auth()->user()->publish(
new Post(request(['title', 'body']))
);
return redirect('/');
}
in user.php
public function posts()
{
return $this->belongsToMany(Post::class);
}
public function publish(Post $post)
{
$this->posts()->save($post);
}
the thing is after login I am seeing the all posts associate with only logged in user but i want many posts to many user relation

Answer 1

The user model must be like this
class User extends Authenticatable
{
public function Posts()
{
return $this->belongsToMany('App\Post');
}
}
The post model must be like this.
class Post extends Model
{
public function users()
{
return $this->belongsToMany('App\User');
}
}
The migration class for user
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email')->unique();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}
The migration class for Post
class CreatePostsTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('posts', function (Blueprint $table) {
$table->increments('id');
$table->string('title');
$table->text('body');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('posts');
}
}
Also u need a pivot table. The table name must be - user_post
class CreatePostUser extends Migration
{
/**
* Run the migrations.
*
* #return void
* user_post
*/
public function up()
{
Schema::create('post_user', function(Blueprint $table)
{
$table->integer('user_id')->unsigned()->nullable();
$table->foreign('user_id')->references('id')
->on('users')->onDelete('cascade');
$table->integer('post_id')->unsigned()->nullable();
$table->foreign('post_id')->references('id')
->on('posts')->onDelete('cascade');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('user_post');
}
}
