我对 flask 蓝图有一些烦恼
我的项目结构:
hw
...run.py
...sigcontoj
......__init__.py
......admin
.........__init__.py
.........views.py
.........models.py
......frontend
.........__init__.py
.........views.py
.........models.py
运行.py:
from sigcontoj import create_app
from sigcontoj.frontend import frontend
app = create_app(__name__)
if __name__ == '__main__':
print app.url_map
print app.blueprints
app.run(debug = True)
sigcontoj__init__.py:
from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy
from sigcontoj.frontend import frontend
db = SQLAlchemy()
def create_app(name=__name__):
app = Flask(name, static_path='/static')
app.register_blueprint(frontend, url_prefix=None)
app.secret_key = 'dfsdf1323jlsdjfl'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///soj.db'
db.init_app(app)
return app
sigcontoj\frontend__init__.py:
from flask import Blueprint
frontend = Blueprint('frontend', __name__, template_folder='templates')
sigcontoj\frontend\models.py:
from datetime import datetime
from sigcontoj import db
class News(db.Model):
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(256))
content = db.Column(db.Text)
publish_time = db.Column(db.DateTime, default=datetime.now())
def __repr__(self):
return '<News : %s>' % self.title
sigcontoj\frontend\views.py:
from sigcontoj.frontend.models import News
from sigcontoj.frontend import frontend
@frontend.route('/')
def index():
news = News.query.all()[0:5]
return "hello world"
app.url_map
的输出是
Map([' (HEAD, OPTIONS, GET) -> static>])
而且索引页是404。
我的代码有没有错误?
最佳答案
您遇到的问题是,即使您导入了 frontend
Blueprint,因为您从未导入 views
index
(/
) 路由从未在 frontend
中注册。如果您更新 sigcontoj/__init__.py
以导入 sigcontoj.frontend.views
:
from flask import Flask
from flask.ext.sqlalchemy import SQLAlchemy
from sigcontoj.frontend import frontend
import sigcontoj.frontend.views
然后一切都应该工作。
