laravel 5.8 eloquent: has many relations model

I am creating event information system and want to show tags in posts/show.blade.php.

But I got an error.

Property [name] does not exist on this collection instance

In posts table, I have category_id. And I created post_tag table.

Do I need to create another new table ?

How to show tags in show.blade.php ?

Please give me a hand.

post.php

   public function tags() 
{
    return $this->belongsToMany(Tag::class);

}
public function hasTag($tagId)
    {
        return in_array($tagId, $this->tags->pluck('id')->toArray());
    }

tag.php

public function posts()
{
    return $this->belongsToMany(Post::class);
}

category.php

public function posts()
{
    return $this->hasMany(Post::class);
}

create_posts_table

Schema::create('posts', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('image');
        $table->unsignedBigInteger('category_id');
        $table->string('organizer');
        $table->string('title');
        $table->string('place');
        $table->string('map');
        $table->date('date');
        $table->timestamp('published_at')->nullable();
        $table->text('description');
        $table->timestamps();
    });

create_categories table

Schema::create('categories', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->timestamps();
    });

create_tags table 

Schema::create('tags', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->string('name');
        $table->timestamps();
    });

post_tag table

Schema::create('post_tag', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->integer('post_id');
        $table->integer('tag_id');
        $table->timestamps();
    });

ResultsControllere.php

public function show($id,Post $post)
{
    $post= Post::find($id);
    $post->category;
    $post ->tags;
    return view('posts.show',compact('post'));
}

show.blade.php

Tags:
  <div class="tags">
     {{ $post->tags->name }}
 </div>

According to your defined relationship post has many tags so you cannot access the one to many relationship directly you may have to loop through to get the tag detail e.g name

<div class="tags">
     @foreach($post->tags as $tag)
     {{ $tag->name }}
     @endforeach
</div>

Thanks.

$post->tags should return a collection so there is no property name.

Your show.blade.php code should be:

<div class="tags">
    @foreach($post->tags as $tag)
        {{ $tag->name }}
    @endforech
</div>
