关于4-5文章详情页跳转的问题

路由 

path('detail/<int:article_id>', app01.views.get_detail_page)

index 配置

<div class="col-md-9" role="main">
    <div class="body-main">
        {% for article in article_list %}
        <div>
            <h2><a href="/app01/detail/{{article.article_id}}">{{article.title}}</a></h2>
            <p>{{article.content}}</p>
        </div>
        {% endfor %}
    </div>
</div>

views

def get_detail_page(request,article_id):
    all_article  =Article.objects.all()
    for article in  all_article:
        if article.arcticle_id == article_id:
            curr_article=article
            break
    return render(request,'app01/detail.html',
                   {
                       'curr_article':curr_article
                   })

直接访问文章详情页是访问正常

但在index首页跳转没有获取到id
