Question

伙计们，在尝试注册用户时，我的项目中出现了这个随机错误。

这是从浏览器返回的信息。

{Gender: "M", ReEmail: "heyguys@whatup.com", Birthday: "1/19/1980", Role: "Athlete",…}
Birthday: "1/19/1980"
Country: "United States"
Email: "heyguys@whatup.com"
Gender: "M"
Password:"doesntwork123"
ReEmail:"heyguys@whatup.com"
RePassword:"doesntwork123"
Role:"Athlete"
kwargs:{}
method:"POST"
results:{error: "tuple indices must be integers, not str"}
error: "tuple indices must be integers, not str"

通过使用PyCharm调试器，我已将问题集中到此特定部分

def addUser(self, session, *args, **kwargs):
   try:
    #existingPerson = session.query(person_models.Player).filter(person_models.Player.Email==args['Email']).first()
    print person_models.Player
    print person_models.Player.Email
    existingPerson = session.query(person_models.Player).filter(person_models.Player.Email == args['Email']).first()
    print existingPerson
    if existingPerson is not None:
       return {'error':"User already exists"}
    person_model = getattr(person_models)
    person = person_model(*args)
    session.add(person)
    session.commit()
    return {"response": "User added"}
   except Exception as e:
    return {'error':str(e)}

一旦到达现有人员，它就会直接发送给我。这是它给我“元组索引必须是整数，而不是str”

这是一些额外的代码。

以下是一些代码：

webapi.py

import cherrypy
from api.restBase import jsonDbRest
from person.controllers import PersonController
class PersonAPI:
exposed = True

@jsonDbRest
def GET(self, email=False, **kwargs):
  session = cherrypy.request.db
  pc = PersonController()
  if email in kwargs:
        profile = pc.get(session, **kwargs)
        return {"results":[profile], "count":'1'}
  profile = pc.search(session, **kwargs)
  return {"results":profile.to_dict(), "count":'1'}

@jsonDbRest
def POST(self, *args, **kwargs):
   session = cherrypy.request.db
   pc = PersonController()
   response = pc.addUser(session, *args, **kwargs)
   return {"results": response}

它抱怨第15行。

这是使用代码的另一行：

restbase.py

import cherrypy
import json
from engine import create_session

def jsonDbRest(func):
  def wrapper(self, *args, **kwargs):

  cherrypy.request.db = create_session()

  if 'Content-Length' in cherrypy.request.headers:
     length = cherrypy.request.headers['Content-Length']
     bodytext = cherrypy.request.body.fp.read(int(length))
  else:
     bodytext = ""
  if bodytext != "":
     jsonData = json.loads(bodytext)
  else:
     jsonData = None
  cherrypy.request.json = jsonData
  func_data = func(self, *args, **kwargs)
  data = {"method":func.__name__, "input":jsonData,"kwargs":kwargs}
  if func_data is not None:
     data.update(func_data)
  cherrypy.response.headers['Content-Type'] = 'application/json'
  if "error" in data:
     cherrypy.response.status = "400"
  else:
     cherrypy.response.status = "200"
  cherrypy.request.db.close()
  return json.dumps(data, indent=4)

另一个代码

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.ext.declarative import AbstractConcreteBase
import datetime
import decimal
import netaddr
import sqlalchemy
from time import strftime

class Base(object):
  def to_dict(self):
    dict = {}
    dict = self.__dict__
    remove = '_sa_instance_state'
    dict = {key: value for key, value in dict.items() if key is not remove}
    dict['DateOfBirth'] = dict['DateOfBirth'].strftime('%m/%d/%Yi')

    return dict

def from_dict(self, dict):
  for col in dict:
     setattr(self, col, dict[col])

def to_array(self, columns=[]):
  if len(columns) < 1:
     columns = self.__mapper__.columns.keys()
  data = []
  for col in columns:
     data.append(getattr(self, col))
  return data

def get_columns(self):
  return self.__mapper__.columns.keys()

JsonBase = declarative_base(cls=Base)

Answer 1

我认为你的问题出现在第一个样本上：

existingPerson = session.query(person_models.Player).filter(person_models.Player.Email == args['Email']).first()

尝试使用kwargs代替args：

existingPerson = session.query(person_models.Player).filter(person_models.Player.Email == kwargs['Email']).first()
