如果应用程序是在全局范围内创建的
__初始化__。PY
from flask import Flask
app = Flask(__name__)
app.config.from_object('config')
from app import views
在run.py下面的这段代码将开始使用{strong> views.py 中的whoosh_search
,例如post = Post.query.whoosh_search(name, limit=3).all(
)
run.py
import os
from app import app
from flask.ext.script import Manager
from flask.ext.moment import Moment
from flask.ext.sqlalchemy import SQLAlchemy
import flask.ext.whooshalchemy as whooshalchemy
basedir = os.path.abspath(os.path.dirname(__file__))
app.config['SQLALCHEMY_DATABASE_URI'] =\
'sqlite:///' + os.path.join(basedir, 'post.sqlite')
app.config['SQLALCHEMY_COMMIT_ON_TEARDOWN'] = True
app.config['SECRET_KEY'] = 'hard to guess string'
db = SQLAlchemy(app)
manager = Manager(app)
moment = Moment(app)
class Post(db.Model):
__tablename__ = 'post'
__searchable__ = ['body']
id = db.Column(db.Integer, primary_key=True)
body = db.Column(db.String(140))
timestamp = db.Column(db.DateTime))
def __repr__(self):
return '<Post %r>' % (self.body)
whooshalchemy.whoosh_index(app, Post)
if __name__ == '__main__':
db.create_all()
manager.run()
了解如何使用Flask-WhooshAlchemy实现Application Factory。
__初始化__。PY
from flask import Flask
from flask.ext.bootstrap import Bootstrap
from flask.ext.moment import Moment
from flask.ext.sqlalchemy import SQLAlchemy
from config import config
bootstrap = Bootstrap()
moment = Moment()
db = SQLAlchemy()
def create_app(config_name):
app = Flask(__name__)
app.config.from_object(config[config_name])
config[config_name].init_app(app)
bootstrap.init_app(app)
moment.init_app(app)
db.init_app(app)
from .main import main as main_blueprint
app.register_blueprint(main_blueprint)
return app
如何在app
中使用应用程序工厂注册whooshalchemy.whoosh_index(app, Post)
,以便在{strong> views.py 中使用whoosh_search
,就像在上一个示例中一样。
答案 0 :(得分:0)
在您的应用程序工厂函数fx中。初始化所有应用程序之后,以及注册蓝图之前。您应该导入模型并运行whoosh_index。有点像:
from .model import Post
whooshalchemy.whoosh_index(app, Post)
