Blueprints in Flask "Attribute 'function' object has no attribute 'name'

Traceback (most recent call last):
  File "/Users/home/PycharmProjects/Demo/Run.py", line 9, in <module>
    app = Create_apps()
  File "/Users/home/PycharmProjects/Demo/apps/__init__.py", line 14, in Create_apps
    register_blueprints(app)
  File "/Users/home/PycharmProjects/Demo/apps/__init__.py", line 19, in register_blueprints
    app.register_blueprint(Admin)
  File "/Library/Python/2.7/site-packages/flask/app.py", line 65, in wrapper_func
    return f(self, *args, **kwargs)
  File "/Library/Python/2.7/site-packages/flask/app.py", line 958, in register_blueprint
    if blueprint.name in self.blueprints:
AttributeError: 'function' object has no attribute 'name'

从报错种可以看到是 register_blueprints(app) 注册 Bluprint 的时候报错，然后走到下一步就是注册 Admin 这个视图的时候报错了。看到 apps\Admin\Views.py 代码中首先注册了这个视图路由命名为 Admin，写下一个测试 def Admin(): 的时候因为视图路由本身即是用 Admin 命名，因为定义了一个函数 Admin 产生冲突然后报错。

做一个小测试就知道了！

from flask import Flask
app = Flask(__name__)
@app.route('/')
def app():
...     return 'test page!'
...
app.run()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'function' object has no attribute 'run'

这样报错的原因就是定义的路由 app 再自定义一个函数 app 导致冲突报错。

下面是正确的代码。

from flask import Flask
app = Flask(__name__)
@app.route('/')
def apps():
...     return 'test page!'
...
app.run()
