                  问题描述

                  搜索了一段时间后,我没有找到任何明确的解决方案

                  After searching a while i didn't find any clear solution

                  文件:models.py

                  class BaseModel(models.Model):
                      created_date = models.DateTimeField(auto_now_add=True)
                      modified_date = models.DateTimeField(auto_now=True)
                  
                      class Meta:
                          abstract = True
                  
                  
                  class Company(BaseModel):
                      company_name = models.CharField(max_length=50, unique=True)
                  
                      def __str__(self):
                          return self.company_name
                  

                  文件:models.py

                  from django.contrib import admin
                  from .models import Company
                  
                  class CompanyAdmin(admin.ModelAdmin):
                      pass
                  
                  admin.site.register(Company, CompanyAdmin)
                  

                  我在这里尝试了解决方案:Django admin model Inheritance is可能吗? 但没有任何效果,管理员只显示公司名称

                  I tried the solution here: Django admin model Inheritance is it possible? but nothing works, and the admin is only showing the company_name

                  推荐答案

                  这些字段没有显示在后台的原因是 auto_nowauto_now.您需要做的是将它们显式添加为只读字段:

                  The reason why those fields are not being showed in the admin, is because of the auto_now and auto_now. What you need to do is adde them explicitly as read-only fields:

                  admin.py

                  from django.contrib import admin
                  from .models import Company
                  
                  class CompanyAdmin(admin.ModelAdmin):
                      readonly_fields = ('created_date', 'modified_date')
                  
                  admin.site.register(Company, CompanyAdmin)
