Django admin 在模型保存期间返回自定义错误消息

Question

我想在 save_model 中返回一些自定义错误消息Django 管理页面的功能。

class EmployerAdmin(admin.ModelAdmin):
  exclude = ('update_user','updatedate','activatedate','activate_user')

  def save_model(self, request, obj, form, change):
    if obj.department != None and obj.isDepartmentSuggested:
        obj.isDepartmentSuggested =False
    else:
       return "You don't set a valid department. Do you want to continue ?"

    obj.update_user = request.user
    obj.updatedate = datetime.datetime.now()
    obj.save()

当然， Else部分不正确，但我想说明我想要什么。

我很高兴向我建议一种方法或文件来做到这一点。
谢谢

您需要使用表单在 EmployerAdmin 中进行验证:

#forms.py
from your_app.models import Employer

class EmployerAdminForm(forms.ModelForm):
    class Meta:
        model = Employer

    def clean(self):
        cleaned_data = self.cleaned_data
        department = cleaned_data.get('department')
        isDepartmentSuggested = cleaned_data.get('isDepartmentSuggested')
        if department == None and not isDepartmentSuggested:
            raise forms.ValidationError(u"You haven't set a valid department. Do you want to continue?")
        return cleaned_data

#admin.py
from django.contrib import admin
from your_app.forms import EmployerAdminForm
from your_app.models import Employer

class EmployerAdmin(admin.ModelAdmin):
    exclude = ('update_user','updatedate','activatedate','activate_user')
    form = EmployerAdminForm

admin.site.register(Employer, EmployerAdmin)

希望能帮到你。
