問題描述

我想用WhooshAlchemy做全文搜索，但是用的時候報錯：

我的config.py：import osfrom app import basedirCSRF_ENABLED = TrueSECRET_KEY = ’hard to guess string’SQLALCHEMY_TRACK_MODIFICATIONS = Falsebasedir = os.path.abspath(os.path.dirname(__file__))WHOOSH_BASE = os.path.join(basedir, ’search.db’)__init__.py：

def create_app():

app = Flask(__name__)app.config.from_pyfile(’config’)app.config[’SQLALCHEMY_DATABASE_URI’] = ’sqlite:///’ + path.join(basedir, ’data.sqlite’)# ’mysql://root:123456@localhost/shop’app.config[’SQLALCHEMY_COMMIT_ON_TEARDOWN’] = Trueapp.config.from_object(’config’)db.init_app(app)bootstrap.init_app(app)login_manager.init_app(app)from auth import auth as auth_blueprintfrom main import main as main_blueprint

models.py：class Post(db.Model):

__tablename__ = ’posts’__searchable__ = [’title’]id = db.Column(db.Integer, primary_key=True)title = db.Column(db.String)body = db.Column(db.String)created = db.Column(db.DateTime, index=True, default=datetime.utcnow)clicks = db.Column(db.Integer)comments = db.relationship(’Comment’, backref=’post’, lazy=’dynamic’)author_id = db.Column(db.Integer, db.ForeignKey(’users.id’))

if enable_search:

whooshalchemy.whoosh_index(app, Post)

問題解答

報錯已經很明顯了，whoosh_index函數要的是app ,但你轉入create_app函數，檢查下吧！
