Instead of belongsTo, use hasMany in Laravel
For belongsTo relationship, instead of passing parent's ID when creating child record, use hasMany relationship to make a shorter sentence.
Example:
if Post -> belongsTo(User)
and User -> hasMany(Post)
instead of passing user_id:
Post::create([
'user_id' => auth()->id(),
'title' => request()->input('title'),
'post_text' => request()->input('post_text'),
]);
Do this:
auth()->user()->posts()->create([
'title' => request()->input('title'),
'post_text' => request()->input('post_text'),
]);
