我将Django从1.6升级到1.7。
现在我在“管理”面板中收到此错误：

我应该在代码中做出哪些更改，以便我可以使用Django 1.7？
我是否必须在某些相关领域进行更改？
编辑：
models.py
from django.db import models
from django.contrib.auth.models import AbstractUser
from django.core.validators import RegexValidator
# Create your models here.
GENDER_CHOICES = (
('M', 'Male'),
('F', 'Female'),
)
class UserProfile(AbstractUser):
dob=models.DateTimeField(blank=True,null=True)
gender = models.CharField(max_length=1, choices=GENDER_CHOICES, null=True,blank=True)
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
phone_number = models.CharField(validators=[phone_regex], blank=True,max_length=16,null=True) # validators should be a list
location=models.CharField(max_length=30,null=True,blank=True)
about=models.CharField(max_length=140,null=True,blank=True)
admin.py
from django.contrib import admin
# Register your models here.
from myapp.models import UserProfile
class user_index_Admin(admin.ModelAdmin):
def get_readonly_fields(self, request, obj=None):
if obj:
return UserProfile._meta.get_all_field_names()
else:
return []
def has_delete_permission(self, request, obj=None):
return False
admin.site.register(UserProfile,user_index_Admin);
答案 0 :(得分：3)
错误在此行的管理类中：
return UserProfile._meta.get_all_field_names()。我想把所有的字段都只读。我根据此SO answer更改了代码，但它确实有效。
admin.py
from django.contrib import admin
# Register your models here.
from myapp.models import UserProfile
class user_index_Admin(admin.ModelAdmin):
def get_readonly_fields(self, request, obj=None):
if obj:
return [f.name for f in self.model._meta.fields]
else:
return []
def has_delete_permission(self, request, obj=None):
return False
admin.site.register(UserProfile,user_index_Admin);
