Question

我正在尝试使用Django进行投票，但我对它很新，当我转到管理员时它会出现此错误：

ImproperlyConfigured at /admin/polls/poll/1/
'PollAdmin.fields' refers to field 'None' that is missing from the form.

我不太确定这意味着什么，但这是我的admin.py文件，我认为这会导致错误：

from django.contrib import admin
from polls.models import Poll

class PollAdmin(admin.ModelAdmin):
  fields = [
    (None,         {'fields': ['question']}),
    ('Date information', {'fields': ['pub date']}),

admin.site.register(Poll, PollAdmin)

修改：

如果重要的话，这是我的模型文件：

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

class Poll(models.Model):
  question = models.CharField(max_length = 200)
  pub_date = models.DateTimeField('date published')
  def __unicode__(self):
    return self.question
  def was_published_recently(self):
    return self.pub_date >= timezone.now() - datetime.timedelta(days = 1)

class Choice(models.Model):
  poll = models.ForeignKey(Poll)
  choice_text = models.CharField(max_length = 200)
  votes = models.IntegerField()
  def __unicode__(self):
    return self.choice_text

编辑（再次）

现在我修改了我的PollAdmin类：

class PollAdmin(admin.ModelAdmin):
  fieldsets = [
    (None,         {'fields': ['question']}),
    ('Date information', {'fields': ['pub_date']}),
  ]

但是它说：

DoesNotExist at /admin/polls/poll/1/
Site matching query does not exist.

Answer 1

使用字段集代替字段：

class PollAdmin(admin.ModelAdmin):
  fieldsets = [
    (None,         {'fields': ['question']}),
    ('Date information', {'fields': ['pub_date']}),

'PollAdmin.fields'指的是表单中缺少的字段'None'
