Django管理模式字段设置为当前用户

Question

我有一个领域的典范：

class MyModel(models.Model): 
    name = models.CharField(max_length=50) 
    created_by = models.ForeignKeyField(User) 

在我的管理：

class MyModelAdmin(admin.ModelAdmin): 
    list_display= ("name",) 
    fields = ("name",) 

在这里我不想created_by的管理，同时增加为MyModel。我希望它被设置为当前用户，如created_by = request.user

我该怎么做？

谢谢

Answer 1

您已经设置fields使created_by没有出现在形式Django管理。

现在您需要覆盖save_model，并在保存新对象之前设置用户。

class MyModelAdmin(admin.ModelAdmin): 
    fields = ("name",) 

    def save_model(self, request, obj, form, change): 
     if not change: 
      # the object is being created, so set the user 
      obj.created_by = request.user 
     obj.save() 

Answer 2

为了做到这一点重写save_model方法和created_by字段设置为当前用户。

class MyModelAdmin(admin.ModelAdmin): 
    list_display= ("name",) 
    fields = ("name",) 

    def save_model(self, request, obj, form, change):    
     if not change: 
     # can use this condition also to set 'created_by'  
     # if not getattr(obj, 'created_by', None):    
      obj.created_by = request.user 
     obj.save()
