燒瓶異常「查看功能映射覆蓋現有的端點功能」

Question

我正在關注這本名爲「燒瓶網頁開發」的書。

當我創建他創建的登錄系統時，我可以在註冊我製作的藍圖時發生異常。

登錄：

C:\Python27\python.exe "C:/Users/Bo/Google Drev/Privat/HobbyProjekter/Event/manage.py" 
Traceback (most recent call last): 
    File "C:/Users/Bo/Google Drev/Privat/HobbyProjekter/Event/manage.py", line 7, in <module> 
    app = create_app(os.getenv('FLASK_CONFIG') or 'default') 
    File "C:\Users\Bo\Google Drev\Privat\HobbyProjekter\Event\app\__init__.py", line 42, in create_app 
    app.register_blueprint(auth_blueprint, url_prefix='/auth') 
    File "C:\Python27\lib\site-packages\flask\app.py", line 62, in wrapper_func 
    return f(self, *args, **kwargs) 
    File "C:\Python27\lib\site-packages\flask\app.py", line 889, in register_blueprint 
    blueprint.register(self, options, first_registration) 
    File "C:\Python27\lib\site-packages\flask\blueprints.py", line 153, in register 
    deferred(state) 
    File "C:\Python27\lib\site-packages\flask\blueprints.py", line 172, in <lambda> 
    s.add_url_rule(rule, endpoint, view_func, **options)) 
    File "C:\Python27\lib\site-packages\flask\blueprints.py", line 76, in add_url_rule 
    view_func, defaults=defaults, **options) 
    File "C:\Python27\lib\site-packages\flask\app.py", line 62, in wrapper_func 
    return f(self, *args, **kwargs) 
    File "C:\Python27\lib\site-packages\flask\app.py", line 984, in add_url_rule 
    'existing endpoint function: %s' % endpoint) 
AssertionError: View function mapping is overwriting an existing endpoint function: auth.login 

對於其中註冊我的藍圖中的代碼看起來是這樣的：

from .auth import auth as auth_blueprint 
app.register_blueprint(auth_blueprint, url_prefix='/auth') 

從我auth__init__.py代碼進口：

from flask import Blueprint 

auth = Blueprint('auth', __name__) 

from . import views 
from flask import render_template 
from . import auth 

@auth.route('/login') 
def login(): 
    return render_template('auth/login.html') 

在最後我的觀點我試圖註冊（只是一個片段）：

@auth.route('/login', methods=['GET', 'POST']) 
def login(): 

希望你能幫助

你有2個端點稱爲 '/登錄'。改變他們的名字。此外，這些功能也不能具有相同的名稱。
