python - error 'function' object has no attribute 'config' when using WhooshAlchemy

Question

I want to use WhooshAlchemy for full-text search, but when I use it, I get an error:

My config.py:
import os
from app import basedir
CSRF_ENABLED = True
SECRET_KEY = 'hard to guess string'
SQLALCHEMY_TRACK_MODIFICATIONS = False
basedir = 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'] = True
app.config.from_object('config')
db.init_app(app)
bootstrap.init_app(app)
login_manager.init_app(app)
from auth import auth as auth_blueprint
from 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)

Answer 1

The error is already obvious. The whoosh_index function requires app, but you switch to the create_app function and check it out!
