评论列表

修改comment_list评论列表视图

@admin.route("/comment/list/<int:page>")
@admin_login_require
def comment_list(page=None):
    if page is None:
        page = 1
    page_comments = Comment.query.join(
        Movie
    ).join(
        User
    ).filter(
        Movie.id == Comment.movie_id,
        User.id == Comment.user_id
    ).order_by(
        Comment.add_time.desc()
    ).paginate(page=page, per_page=10)
    return render_template('admin/comment_list.html', page_comments=page_comments)

修改comment_list.html评论列表模板

<div class="box-body box-comments">
    {% include 'admin/alert_info.html' %}

    {% for comment in page_comments.items %}
        <div class="box-comment">
            <img class="img-circle img-sm"
                 src="{{ url_for('static',filename='user/'+comment.user.face) }}" alt="User Image">
            <div class="comment-text">
                <span class="username">
                    {{ comment.user.name }}
                    <span class="text-muted pull-right">
                        <i class="fa fa-calendar" aria-hidden="true"></i>
                        &nbsp;
                        {{ comment.add_time }}

                </span>
                关于电影<a>《{{ comment.movie.title }}》</a>的评论：{{ comment.content }}
                <br><a class="label label-danger pull-right">删除</a>
            </div>

    {% endfor %}

    db.session.delete(comment)
    db.session.commit()
