Exception Type: KeyError at /admin/myapp/userprofile/1/
Exception Value: u'manager'

我应该对代码进行哪些更改才能使其与 Django 1.7 一起使用？

我是否必须在某些相关字段中进行更改？

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);

Answer 1

错误出现在管理员 class 的这一行中： return UserProfile._meta.get_all_field_names()。我想让所有字段只读。我根据这个 SO answer 更改了代码并且它起作用了。

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);
