            raise ValidationError("密码不一致")
        # 返回什么，此字段以后保存到数据库就是什么。
        return confirm


def admin_add(request):
    """ 添加管理员 """
    title = "新建管理员"
    if request.method == "GET":
        form = AdminModelForm()
        return render(request, 'change.html', {'form': form, "title": title})

1.3 重置密码

class AdminResetModelForm(BootStrapModelForm):

        }

    def clean_password(self):       # 钩子方法
        pwd = self.cleaned_data.get("password")
        md5_pwd = md5(pwd)

        # 去数据库校验当前密码和新输入的密码是否一致
        exists = models.Admin.objects.filter(id=self.instance.pk, password=md5_pwd).exists()
        if exists:
            raise ValidationError("不能与以前的密码相同")

        return md5_pwd

    def clean_confirm_password(self):   # 钩子方法
        pwd = self.cleaned_data.get("password")
        confirm = md5(self.cleaned_data.get("confirm_password"))
        if confirm != pwd:
            raise ValidationError("密码不一致")
        # 返回什么，此字段以后保存到数据库就是什么。
        return confirm
def admin_reset(request, nid):
    """ 重置密码 """
    # 对象 / None
    row_object = models.Admin.objects.filter(id=nid).first()
    if not row_object:
        return redirect('/admin/list/')

    title = "重置密码 - {}".format(row_object.username)     # 重置谁的密码

    if request.method == "GET":
        form = AdminResetModelForm()
        return render(request, 'change.html', {"form": form, "title": title})

    form = AdminResetModelForm(data=request.POST, instance=row_object)
    if form.is_valid():
