“question_text”是此函数的无效关键字参数

Question

我试图遵循Polls教程，包括来自项目的urls.py，以及Polls目录中的models.py。在

q = Question(question_text="some text", pub_date=timezone.now))

导致以下错误：

投票/模型.py

import datetime
from django.db import models
from django.utils import timezone

# Create your models here.

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')


class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

    def __str__(self):
        return self.question_text

    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)


class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

    def __str__(self):
        return self.choice_text

我认为在学习教程的过程中，您已经做了很多代码更改，而这些并没有反映在sql数据库中。在

所以，在做以上步骤之前，请遵循下面的步骤。在

python manage.py migrate
python manage.py makemigrations polls
python manage.py migrate

现在就这么做
