管理中的 django ValidationError save_model

Question

Models.py

class user(AbstractUser):
    salary_number = models.IntegerField(unique=True, null=True, blank=True)

Admin.py

def save_model(self, request, obj, form, change):
    if obj.salary_number == None:
        raise ValidationError("ERROR salary number!")
    ....
    obj.save()

如果用户忘记填写工资号码，我试图向他们显示错误，但我在 /admin/information/user/add/ 处收到错误 ValidationError。我该如何解决？

我有理由不设置 salary_number null & blank = False。

最简单的方法大概就是做一个小的ModelForm:

from django import forms
from django.core.exceptions import ValidationError

class UserModelForm(forms.ModelForm):
    
    def <strong>clean_salary_number</strong>(self):
        data = self.cleaned_data['salary_number']
        if data is None:
            raise ValidationError('ERROR salary number!')
        return data

然后将其插入 ModelAdmin:

from django.contrib import admin

class MyModelAdmin(admin.ModelAdmin):
    # …
    <strong>form = UserModelForm</strong>
