Blog is not displayed or stored correctly in the database

Question

Once I delete a blog, it is completely deleted. I can create a new blog but it won't show up on the website or database. This is my BlogController:

<?php

namespace App\Http\Controllers;

use App\Models\Blog;
use Illuminate\Http\Request;

class BlogController extends Controller
{
    /*** Display resource list.
     *
     * @return \Illuminate\Http\Response*/
   
    public function index()
    {
        $blog = Blog::paginate(5);
        return view('blogs.index', compact('blog'))
            ->with('i',(request()->input('page',1)-1)*5);
    }

    /*** Display the form for creating new resources.
     *
     * @return \Illuminate\Http\Response*/
    public function create()
    {
        return view('blogs.create');
        
        Blog::create($request->all());
   
        return redirect()->route('blogs.index')
                        ->with('success','The blog was created successfully.');
    }
  
    /*** Store newly created resources in storage.
     *
     * @param \Illuminate\Http\Request $request
     * @return \Illuminate\Http\Response*/
    public function store(Request $request)
    {
        $request->validate([
            'title' => 'required',
            'description' => 'required',
        ]);

        $blog = new Blog;
       
        $blog->title = $request->title;
 
        $blog->description = $request->description;

        $blog->save();
        
        return redirect()->route('blogs.index');

    }
   
    /*** Display the specified resource.
     *
     * @param \App\Blog $blog
     * @return \Illuminate\Http\Response*/
    public function show(Blog $blog)
    {
        return view('blogs.show', compact('blog'));
    }
   
    /*** Display the form for editing the specified resource.
     *
     * @param \App\Blog $blog
     * @return \Illuminate\Http\Response*/
    public function edit(Blog $blog)
    {
        return view('blogs.edit', compact('blog'));
    }
  
    /*** Update the specified resource in storage.
     *
     * @param \Illuminate\Http\Request $request
     * @param \App\Blog $blog
     * @return \Illuminate\Http\Response*/
    public function update(Request $request, Blog $blog)
    {
        $request->validate([
            'title' => 'required',
            'description' => 'required',
        ]);

        // $blog->title = $request->title;
 
       // $blog->description = $request->description;

        $blog->fill($request);
        
        //dd($blog);

        return redirect()->route('blogs.index')
                        ->with('success','Blog updated successfully');

    }
  
    /**
     * Remove the specified resource from storage.*
     * @param \App\Blog $blog
     * @return \Illuminate\Http\Response
     */
    public function destroy(Blog $blog)
    {
        $blog->delete();
  
        return redirect()->route('blogs.index')
                        ->with('success','Blog deleted successfully');
    }
   

}

The problem apparently occurs at line 103, public function update: $blog->fill($request); It is neither stored in the database nor in the web page/blog visible. I tried removing that line but got the same result. Nothing changes. I don't understand what the problem could be. Can anyone help?

Answer 1

First optionIn order for the fill method to work, you must call $blog->save() after this.

$blog->fill($request); 
$blog->save();

Also, when you use the fill method, you are doing a bulk assignment. By default, Laravel protects you from bulk-assigned fields.

Open your Blog.php model and add the fields you want to batch assign to the array $fillable

/**
 * 可以批量赋值的属性。
 *
 * @var array
 */
protected $fillable = [
    'title',
    'description',
];

The second option is to use the update method (don’t forget to also add fields to $fillable in the model of the first option because ## The #update method is also a batch assignment field):

$blog->update($request);

The third option is to manually assign each field one by one, just like you did in the store method:

$blog->title = $request->title;
 
$blog->description = $request->description;

$blog->save();
