1. 比较隐蔽的一个问题，问题代码如下
from app.settings import settings | |
# the name settings refers to the blueprint imported above | |
@settings.route('/a') | |
def this_works(): | |
... | |
# the name settings refers to the blueprint imported above | |
@settings.route('/') | |
def settings(): | |
... | |
# the name settings now refers to the function defined above | |
@settings.route('/b') | |
def this_fails(): | |
... |
2. 造成原因是函数名和路由名一样了，解决办法给路由起别名或者改变上面第二个方法的函数名字（不要叫 settings - 即不要和 blueprint 的 settings 一样）
from app.settings import settings as bp | |
@bp.route('/') | |
def settings(): | |
pass |
