Call to undefined relationship [user] on model [App\Models\Post]

• Get user/author detail using belongsTo relation on post model

  //app\Models\Post.php
  class Post extends Model
  {
  
      //Add user method in existing post model
      public function user(){
          return $this->belongsTo('App\Models\User');
      }
  }
  
  //Code snippet to get the user/author details with post.
  $data = Post::with('user')->first();
  dd($data);
  
  //Import post model after the namespace in controller or anywhere you want to use the above code
  use App\Models\Post;
  

  You have to create a user method with belongsTo relationship in the post model. It helps you to get the user or author information using the user_id (foreign_id) of the posts table and id (primary key) column of users table.
