'function' object has no attribute 'name' when registering blueprint

Question

Here is my project layout:

baseflask/
   baseflask/
      __init__.py
      views.py
      resources/
          health.py/
   wsgi.py/

Here is my print

from flask import Blueprint
from flask import Response
health = Blueprint('health', __name__)
@health.route("/health", methods=["GET"])
def health():
    jd = {'status': 'OK'}
    data = json.dumps(jd)
    resp = Response(data, status=200, mimetype='application/json')
    return resp

How I register in __init__.py:

import os
basedir = os.path.abspath(os.path.dirname(__file__))
from flask import Blueprint
from flask import Flask
from flask_cors import CORS, cross_origin
app = Flask(__name__)
app.debug = True

CORS(app)

from baseflask.health import health
app.register_blueprint(health)

Here is the error:

Traceback (most recent call last):
  File "/home/ubuntu/workspace/baseflask/wsgi.py", line 10, in <module>
    from baseflask import app
  File "/home/ubuntu/workspace/baseflask/baseflask/__init__.py", line 18, in <module>
    app.register_blueprint(health)
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 62, in wrapper_func
    return f(self, *args, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 880, in register_blueprint
    if blueprint.name in self.blueprints:
AttributeError: 'function' object has no attribute 'name'

Answer 1

You masked the health global name referring to Blueprint instance, by re-using the name for the view function:

health = Blueprint('health', __name__)
@health.route("/health", methods=["GET"])
def health():

You can’t have both the route view function and the blueprint use the same name; you replaced the global name health that referred to the blueprint and are trying to register the route function for the same global name.

Use a different name for the blueprint:

health_blueprint = Blueprint('health', __name__)

and register that:

from baseflask.health import health_blueprint
app.register_blueprint(health_blueprint)

or use a different name for the view function (at which point the endpoint name changes too unless you explicitly use endpoint='health' in the @health.route(...) decorator).

Answer 2

health = Blueprint('health', __name__)
@health.route("/health", methods=["GET"])
def health():

Your blueprint name is same with your function name, try to rename the function name instead.

health = Blueprint('health', __name__)
@health.route("/health", methods=["GET"])
def check_health():
