如何创建躁动如烧瓶的蓝图

Question

我不知道该怎么做。

蓝图api:

# coding: utf-8
from flask import Blueprint, render_template
from ..models import User
from flask_restless import APIManager
manager = APIManager()
manager.create_api(User, url_prefix='/api', methods=['GET', 'POST', 'DELETE', 'PUT', 'PATCH'])
bp = Blueprint('api', __name__)

__init__.py:

def register_db(app):
    from .models import db
    db.init_app(app)
def register_api(app):
    from .controllers.api import manager
    manager.init_app(app, flask_sqlalchemy_db=db)

注册蓝图:

def register_routes(app):
    from . import controllers
    from flask.blueprints import Blueprint
for module in _import_submodules_from_package(controllers):
    bp = getattr(module, 'bp')
    if bp and isinstance(bp, Blueprint):
        app.register_blueprint(bp)

我得到这个错误时，试图启动:

RuntimeError: application not registered on db instance and no application bound to current context

如果我排除方法=['GET'， 'POST'， 'DELETE'， 'PUT'， 'PATCH']，应用程序启动，但如果我尝试发送请求http http://0.0.0.0:5000/api/user，显然，我得到答案:

HTTP/1.0 500 INTERNAL SERVER ERROR
Content-Length: 291
Content-Type: text/html
Date: Thu, 20 Oct 2016 15:33:52 GMT
Server: Werkzeug/0.11.11 Python/3.5.2

Docs没有给出解决问题的例子

你能告诉我答案在哪里吗

Answer 1

这行得通:

蓝图:

# coding: utf-8
from flask import Blueprint, render_template
from flask_restless import APIManager
from ..models import db

bp = Blueprint('api', __name__)
manager = APIManager(flask_sqlalchemy_db=db)

init.py:

def register_api(app):
    """Register api."""
    from .controllers.api import manager
    from .models import User
    manager.init_app(app)
    manager.create_api(User, app=app)

请求:http http://0.0.0.0:5000/api/user

反应:
