Laravel 5.5 Method update doesn't exist

I'm trying to create a blog but I keep getting this error.

BadMethodCallException Method update does not exist.

I'm trying to edit posts and update the database.

public function update(Request $request, Post $post)
{
    $posts = Post::Find($post);

    $posts->update($request->all());
}

you are already accepting the Post object via the method

rather doing something like this

public function update(Request $request, Post $post)
{
    $posts = Post::Find($post);

    $posts->update($request->all());
}

do it like this 

public function update(Request $request, Post $post)
{  

    // you already have the Post object injected from the framework for you.
    // you can use the instance freely.
    $post->update($request->all());
}

of cause, it might be a good thing to check if the $post object is null or not but laravel will throw ModelNotFoundException if you don't have any matches in the database.

This is something called Route Model Binding which laravel 5.5 does for you if you keep the settings as default, as in using the primary key 'id'. you can read more about this on this https://laravel.com/docs/5.5/routing#route-model-binding

Do directly:

public function update(Request $request, Post $post) {

    $post->update($request->all());

}

$post is already an instance of Post model if the route was declared as:

Route::get('posts/update/{post}', 'PsotsController@update');

$posts = Post::find($post->id);

find() accepts only primary id
