Updating the Post

To update the post we need to work two routes and two methond in the PostController 

posts/{post}/edit //GET
posts/{post} // PUT

We need to update the PostController and create a view for the edit form

  <form method="POST" action="{{ route('posts.update',$post->id) }}">
                            @csrf
                            @method('PUT')

This view is likely to be similar to the create post view but you will need to 

• update the form action to call the new route
• add the existing values into the form

resources/views/posts/edit.blade.php

   <form method="POST" action="{{ route('posts.update') }}">
                            @csrf
                            @method('PUT')

   /**
     * Update the specified resource in storage.
     */
    public function update(Request $request, Post $post)
    {

        $request->validate([
            'title' => 'required',
            'body' => 'required',
        ]);
        
        Post::where('id', $post->id)->update(
            [
                'title' => $request->title,
                'body' => $request->body,
                'user_id' => 1  //or whatever user you want associated with the update
            ]
        );

        return redirect()->route('posts.index')->with('success', 'Post updated successfully.');
    }

Common error: Model::update() should not be called statically
