django admin.py 如何定制错误信息提示？

问题解决了 定义一个form就行 例：

from django import forms

class BookForm(forms.ModelForm):
    class Meta:
        model = Book

    def clean(self):
        prince = self.cleaned_data.get('prince')
        if isinstance(price, int):
            raise forms.ValidationError(u'价格应为数字')
        return self.cleaned_data

class BookAmin(admin.ModelAdmin):
    form = BookForm
    llist_display = ('name', 'price')

    def save_model(self, request, obj, form, change):
        cdata = form.cleaned_data
        obj.save()

admin 里加入 form = BookForm就行了，如果想要传值可以使用cleaned_data。
