flask - 如何初始化不安分作为 flask 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)

尝试启动时出现此错误:

RuntimeError: 应用程序未在数据库实例上注册并且没有应用程序绑定(bind)到当前上下文

如果我排除 methods=['GET', 'POST', 'DELETE', 'PUT', 'PATCH']，则应用程序已启动，但如果我尝试发送请求 http http://0.0.0.0:5000/api/user ，显然，我得到了答案:

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

你能告诉在哪里可以找到答案吗

Answer 1

这有效:

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)

初始化.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
回复 :
