问题描述

  class BannerAddPage(models.Model)类:BOOL_CHOICES =((真，'实时')，(假，'暂停'))TYPE_CHOICES =((('文本'，'文本')，('图像'，'图像')))category = models.ForeignKey(Category，blank = True)client = models.ForeignKey(客户)ad_type = models.CharField(choices = TYPE_CHOICES，default = True)ad_name = models.CharField(max_length = 800，null = True，blank = True)ad_title = models.CharField(max_length = 800，null = True，blank = True)ad_url1 = models.URLField(max_length = 800，blank = True，null = True)ad_banner2 = models.ImageField(upload_to = upload_to1，blank = True，null = True)

我想在点击 ad_type(choice)字段后隐藏一些字段.

解决方案

最好的方法是使用表单媒体添加一个外部javascript文件，该文件将侦听ad_type字段的change事件并执行所需的操作.

在这种情况下，您将需要很少的python和更多的js，但我认为这是干净的方法.

要添加外部js文件，请使用媒体类，此 answer 可以另一个问题显示了一个实际例子.

除了只需要编写js代码之外，您还可以使用django admin中已包含的jQuery.

希望这会有所帮助

class BannerAddPage(models.Model):
    BOOL_CHOICES = ((True, 'Live'), (False, 'Pause'))
    TYPE_CHOICES = (('text', 'text'), ('image', 'image'))
    category=models.ForeignKey(Category,blank=True)
    client=models.ForeignKey(Client)
    ad_type=models.CharField(choices=TYPE_CHOICES,default=True)
    ad_name=models.CharField(max_length=800,null=True,blank=True)
    ad_title=models.CharField(max_length=800,null=True,blank=True)
    ad_url1=models.URLField(max_length=800,blank=True,null=True)
    ad_banner2=models.ImageField(upload_to=upload_to1,blank=True,null=True)

I want to hide some fields after click on ad_type(choice) field.

解决方案

Best way is to use form media to add an external javascript file that will listen to the change event of the field ad_type and perform the action you need.

In this case you will need little python and lot more of js, but I think is the clean way.

To add the external js file use the class Media, this answer to another question shows a practical example.

Than you just have to have fun with writing js code, you can use the jQuery already included in django admin.

Hope this helps
