def get_detail_page(request, article_id):

    # print(article_id)

    curr_article = Article.objects.get(article_id=article_id)

    try:

        previous_article = Article.objects.get(article_id=article_id-1)

    except Exception as e:

        previous_article = dict()

        previous_article['article_id'] = article_id

        previous_article['title'] = '没有了-.-'

    try:

        next_article = Article.objects.get(article_id=article_id+1)

    except Exception as e:

        next_article = dict()

        next_article['article_id'] = article_id

        next_article['title'] = '没有了-.-'
