Question about the controller function store parameter (tutorial 10 near video time frame 10:08). The "Idea" $idea (not $idea)parameter, is that the model name if not where is it coming from and do you need it. I been following your vides to learn Laravel 10 and I was little confused about the need for the "Idea" parameter. I tried running the function ($idea) like and it seems to work so what is the purpose to "Idea" parameter?

Thanks for watching. Your are correct, that is the model class type Those are called type hints in PHP, you are basically telling php what type of class this function accepts. In php these are optional so your code will still work without it in this case. In has at least 2 main benefits in this case: 1 - it helps your IDE or code editor know what the $idea type is, so you can get auto suggestions. 2 - It also lets laravel know, what model should be used for route model binding if you use a different name than idea in your route web.php file.

good day! where ever you are. Just a question, what does the ($idea) that you always use on codes like $idea->comments, etc. represent? Is it a variable for the model? If so, where can I find it?

not completely sure but i think it's from the foreach at the very beginning of dashboard.blade.php where we render all ideas, since its @include('shared.idea-card'), the idea-card has access to $idea while comments-box is included on the idea-card so comment-box has access to it too, this might be wrong but that's how how i understood it

I did exactly what you learned and idea show and edit page working but when I go back to dashboard ( home page ) it can't load comments and get something like this error " $idea->comments or $idea->id are undefined variables"

Thanks for watching. Are you using a different variable name than $idea in your project? I would check "dashboard.blade.php" as well as "idea-card.blade.php" to see if you are using the variable name $idea or something else. The entire code for this episode is also on github, you can compare your code with it to see what may be the issue. github.com/yelocode/ideas/tree/2bfd88f556c8582fe4afbc745ac6b70789856c48

I had the same issue, forgot to use Idea $idea as inputs in the store function in the CommentController. Without that "use App\Models\Idea" wasn't working and resulted in undefined variables error.
