修改indexbanner首页轮播图视图

@home.route("/indexbanner/")
def indexbanner():
    previews = Preview.query.all()
    return render_template('home/indexbanner.html', previews=previews)

电影搜索页面

修改base.html搜索框功能

禁止输入框回车提交，只能点击搜索按钮，然后添加js代码，获取搜索框的值

<div class="form-group input-group">
    <input type="text" class="form-control" placeholder="请输入电影名！" id="keyword" value="{{ keyword }}"
           onkeydown="if(event.keyCode===13)return false;"
    >
    <span class="input-group-btn">
        <a class="btn btn-default" id="do_search"><span class="glyphicon glyphicon-search"></span>&nbsp;搜索</a>
    </span>
</div>

<script>
    $(document).ready(function () {
        $("#do_search").click(function () {
            let keyword = $('#keyword').val();
            location.href = "{{ url_for('home.search') }}?keyword=" + keyword;
        });
    })
</script>

修改search搜索电影视图

使用模糊搜索

@home.route('/search/')
def search():
    keyword = request.args.get('keyword')
    search_movies = Movie.query.filter(
        Movie.title.ilike("%" + keyword + "%")
    ).order_by(
        Movie.add_time.desc()
    )
    search_count = Movie.query.filter(Movie.title.ilike("%" + keyword + "%")).count()
    return render_template('home/search.html', keyword=keyword, search_movies=search_movies, search_count=search_count)

修改search.html搜索结果显示模板

<div class="col-md-12">
    {% for search_movie in search_movies %}
        <div class="media">
            <div class="media-left">
                <a href="play.html">
                    <img class="media-object" src="{{ url_for('static', filename='media/' + search_movie.logo) }}" alt="{{ search_movie.title }}" style="width: 150px">
                </a>
            </div>
            <div class="media-body">
                <h4 class="media-heading">{{ search_movie.title }}<a href="play.html" class="label label-primary pull-right"><span class="glyphicon glyphicon-play"></span>播放影片</a></h4>
                {{ search_movie.info }}
            </div>
        </div>
    {% endfor %}
</div>

电影标签筛选和列表

修改index电影列表页视图

增加筛选和分页功能

    selected['tag_id'] = tag_id

    star_num = request.args.get('star_num', 0)  # 获取星级数字，0为显示所有

    selected['time_year'] = time_year

    play_num = request.args.get('play_num', 1)  # 1为从高到低，0为从低到好
    if int(play_num) == 1:
        page_movies = page_movies.order_by(
            Movie.play_num.desc()
        )
    else:
        page_movies = page_movies.order_by(Movie.play_num.asc())
    selected['play_num'] = play_num

    comment_num = request.args.get('comment_num', 1)  # 1为从高到低，0为从低到好
    if int(comment_num) == 1:
        page_movies = page_movies.order_by(
            Movie.comment_num.desc()
        )
    else:
        page_movies = page_movies.order_by(Movie.comment_num.asc())
    selected['comment_num'] = comment_num

    page_movies = page_movies.paginate(page=page, per_page=12)
    return render_template('home/index.html',
                           all_tag=all_tag,
                           all_star=all_star,

                           page_movies=page_movies)

修改base.html首页链接增加page

<a href="{{ url_for('home.index', page=1) }}" class="navbar-brand" style="width:250px;">
    <img src="{{ url_for('static', filename='base/images/logo.png') }}" style="height:30px;">&nbsp;微电影

<li>
    <a class="curlink" href="{{ url_for('home.index', page=1) }}"><span class="glyphicon glyphicon-film"></span>&nbsp;电影</a>
