Question

在我的商店方法中保存模型后，我将重定向到确认视图。我想知道如何在保存后将新创建的模型传递给确认视图。感谢。

public function store(Request $request)
    {   
        // validate incoming data
        $this->validate($request, array(
                'title' => 'required|max:191',
                'body'  => 'required',
                'category_id'  => 'required|integer',
                'slug'  => 'required|alpha_dash|min:5|max:191|unique:posts,slug',
                'image' => 'sometimes|image'
            ));
        // store in database
        $post = new Post;
        $post->title = $request->title;
        $post->body = Purifier::clean($request->body);
        $post->category_id = $request->category_id;
        $post->slug = $request->slug;
        if ($request->hasFile('image')) {
            $image = $request->file('image');
            $filename = time() . '.' . $image->getClientOriginalExtension();
            $location = public_path('images/' . $filename);
            Image::make($image)->save($location);
            $post->image = $filename;
        }
        $post->save();
        $post->tags()->sync($request->tags, false);
        // Set flash success message
        Session::flash('success',' The blog post was successfully saved!');

                // I need to pass new model in here            
        return redirect()->route('confirm.posts');
    }

最简单和最常见的方法是在您的路线中包含模型ID。

Route::get('/posts/{post_id}/confirm', 'PostController@getConfirm')->name('post.confirm');

然后在您的控制器中，您将重定向到post.confirm路由并加载模型。

// ...

public function store(Request $request)
{
    // ...        
    return redirect()->route('post.confirm', $post->id);
}

public function getConfirm($postId)
{
    $post = Post::findOrFail($postId);
    // ...
} 

// ...

save（）之后将模型传递给视图;
