Question

好吧，所以我试图允许用户在我使用sqlalchemy设置的数据库中搜索电影/电视节目。我跟着一个教程，能够使用以下代码从我的数据库中将所有电影打印到屏幕上：

<div class="row">
      <div class="col-sm-4 portfolio-item">
        {% for movie in movies %}
        <h2 class="post-title">{{ movie.title }}</h2>
        <p>{{ movie.description }}</p>
        {% endfor %}
      </div>
    </div>

但是，当我尝试添加搜索功能时，什么都不会出现。当我进行搜索时，我得到了这个结果：

SELECT "movieTV".id AS "movieTV_id", "movieTV".title AS 
"movieTV_title", "movieTV"."releaseDate" AS "movieTV_releaseDate", 
"movieTV".producer AS "movieTV_producer", "movieTV".description AS 
"movieTV_description", "movieTV".genre AS "movieTV_genre" 
FROM "movieTV" 
WHERE null

这是我的搜索功能：

@app.route('/', methods=['GET', 'POST'])
def index():
    movies = MovieTV.query.all()
    error = None
    return render_template('index.html', error=error, movies=movies)


@app.route('/search')
def search():
    movies = MovieTV.query.whoosh_search(request.args.get('query'))
    return render_template('index.html', movies=movies)

使用whooshalchemy搜索sqlalchemy数据库
