I wanted to add comment to every post I make but I keep on getting errors.
Comment Controller:
public function store(Request $request)
{
$comments = new Comment;
$comments->body =$request->get('comment_body');
$comments->user()->associate($request->user());
$blogs = Comment::find(1);
$blogs->comments()->save($comments);
return back();
}
Comment Model:
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Comment extends Model
{
use HasFactory;
protected $guarded =[];
public function blog()
{
return $this->belongsTo(Blog::class);
}
public function user()
{
return $this->belongsTo(User::class);
}
}
Blog Model:
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Blog extends Model
{
use HasFactory;
protected $fillable = ['user_id' , 'blog_category_id' , 'title' , 'description'];
public function user()
{
return $this->belongsTo(user::class);
}
public function blogcategory()
{
return $this->hasOne(BlogCategory::class)->withDefault(function($user , $post){
$user->name = "Author";
});
}
public function comments()
{
return $this->hasMany(Comment::class);
}
}
You are using the wrong model; the Blog model has the comments relationship not the Comment model:
$blog = Blog::find(...);
$blog->comments()->save(...);
Update:
You seem to want to be using a Polymorphic relationship it would seem based on the structure of your comments table since you have the fields commentable_id and commentable_type. If you check the documentation for the Polymorphic One to Many relationship this is the same as the example in the documentation:
Blog model:
public function comments()
{
return $this->morphMany(Comment::class, 'commentable');
}
Comment model:
public function commentable()
{
return $this->morphTo();
}
Laravel 8.x Docs - Eloquent - Relationships - Polymorphic Relationships - One to Many
Having said that, your Comment model doesn't look like you wanted to use a polymorphic relationship since you specifically had a blog relationship method. If you do not have more than 1 entity that needs to be related to Comment I would not be using a polymorphic relationship.
