Django 遷移錯誤：錯誤：“選擇”必須是可迭代的（例如，列表或元組）

Question

我為博客應用程序創建了模型。 這是我的models.py：

from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
# Create your models here.
class post(models.Model):
    STATUS_CHOICE=(
        ('draft','DRAFT'),
        ('published','Published'),
    )

    title=models.CharField(max_length=250)
    slug=models.SlugField(max_length = 250,unique_for_date='publish')
    author=models.ForeignKey(User,related_name='blog_posts')
    body=models.TextField()
    publish=models.DateTimeField(default=timezone.now)
    created = models.DateTimeField(auto_now_add=True)
    updated=models.DateTimeField(auto_now=True)
    status = models.CharField(max_length=10,
                                choices = 'STATUS_CHOICES',
                                    default='draft')
    class Meta:
        ordering = ('-publish',)
    def __str__(self):
        return self.title

當我嘗試遷移模型時，出現錯誤：

ERRORS:
myblog.post.status: (fields.E004) 'choices' must be an iterable (e.g., a list or tuple).

這是我的 admin.py 文件：

from django.contrib import admin
from .models import post

# Register your models here.
admin.site.register(post)

請問有人能幫我解決這個問題嗎？

Answer 1

choices需要參考您在上面聲明的列表，而不是字符串：

status = models.CharField(max_length=10,
                            choices = STATUS_CHOICE,
                                default='draft')

Answer 2

請從 STATUS CHOICES 中刪除引號

status = models.CharField(max_length=10,
                        choices = 'STATUS_CHOICES',
                            default='draft')

致：

status = models.CharField(max_length=10,
                        choices = STATUS_CHOICE,
                            default='draft')
