Question

我在model.py中写了我的代码，但是我在开发服务器中遇到了这个错误。欢迎提出任何建议。我已经在stackflow中遵循了之前的建议，但我无法得到解决我的代码的任何答案。错误：下面的代码是我得到的错误。

 Unhandled exception in thread started by <function wrapper at 0x7fe6d63e4938>

                ^
    SyntaxError: invalid syntax

下面是我的model.py

代码

# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.utils import timezone
from django.db import models

# Create your models here.
class tithe(models.models):
    genarationNo = models(ForeignKey('generationNo.User'))
    memberid = models.IntField()
    membername = models.VacharField()
    tithe = models.IntField()
    combinedoffering = models.IntField(max_length=45)
    campmeetingoffering = models.IntField(IntField=45)
    churchbuilding = models.IntField(max_length=45)
    conference = models.IntField(max_length=45)
    localchurch = models.IntField(max_length=45)
    funds = models.IntField(max_length=45)
    total = models.IntField(max_length=45)
    created_date = models.DateTimeField(
            default=timezone.now)
    printed_date = models.DateTimeField(
            blank=True, null=True)

    def print(self):
        self.printed_date = timezone.now()
        self.save()

    def __str__(self):
        return self.generationNo

    class Meta:
        unique_together = ["generationNo","IntField"]
        ordering = ["printed_date","membername"]

Answer 1

print是该语言的关键字。它是保留的，不能用作标识符。 See this

Answer 2

正如其他人所说，print对于函数来说不是一个好名字，但是你的代码还有其他一些奇怪之处。在unique_together中，您引用的是不存在的字段。

我在我的model.py中得到一个SyntaxError，这可能是我的代码的问题
