app.listener('before_server_start') Why is it executed last?
# app/server.py a part...
def create_app():
app = Sanic('app')
@app.listener("before_server_start")
async def test1(app, loop):
print(''first...")
print("second...")
return app
Running results：
second…
first…
I use umongo orm. I will add database connection information in app.listener(“before_server_start”)
# app/server.py. a part..
@app.listener('before_server_start')
async def mongodb_configure(app_inner):
client = AsyncIOMotorClient(app_inner.config.get('MONGODB_URI'))
instance = MotorAsyncIOInstance(client.run)
app.ctx.db = instance
Then add a decorator to the model
# app/model/user.py a part ...
@app.ctx.db.register
class User(Document):
_id = fields.ObjectIdField()
name = fields.StringField(default='', max_length=50, description='The name of the user')
password = fields.StringField(default='', max_length=50, description='The name of the user')
Back to the beginning, If listener executed last, this error will be reported app.ctx.db undefault error
May I ask how to solve it, online, etc. Thank you very much!
