Django管理后台：只有在下拉框选择特定值时才显示某个字段

Question

models.py

class FixedIncome(Asset):
   isin = models.CharField(max_length=6, blank=False)
   coupon = models.DecimalField(max_digits=7, decimal_places=4, help_text="Percent")
   payment_frequency = models.ForeignKey(PaymentFrequency)
   months = models.ManyToManyField(Month, blank = False, verbose_name = "Payment months")
   duration = models.DecimalField(max_digits=4, decimal_places=2, default='0')
   maturity_date = models.DateTimeField(default=datetime.now, blank=False)

   class Meta:
      verbose_name_plural = "Fixed Income"

我希望django admin只在选择月份（数字1到12，下拉框）时显示maturity_date属性。我看过一些关于js的内容，但我不会做:(

我用jquery解决了这个问题，并在我的ModelAdmin上添加了一个名为“Media”的类。

admin.py

class FixedIncomeAdmin(admin.ModelAdmin):
model = FixedIncome
can_delete = False
list_display = ['name', 'country', 'industry', 'isin', 'coupon', 'payment_frequency']
list_filter = ['name', 'isin', 'country', 'industry']
search_fields = ['name', 'isin', 'country', 'industry']

class Media:
    js = ('/static/admin/js/assets_admin.js',)

assets_admin.js

django.jQuery('#id_payment_frequency').change(function(){
if(django.jQuery("#id_payment_frequency option:selected").text() == 0)
    {
        django.jQuery(".form-row.field-months").hide();
    }else
    {
        django.jQuery(".form-row.field-months").show();
    }
});

如果支付频率的选择框（0到12）为0，则表单中的月份将被隐藏。希望能对某人有所帮助！ :)
