如何仅在django-admin中选择下拉菜单中的特定选项时才显示字段

Question

py looks as below,

     class Billing_Detail(models.Model):
        bill_choices = [('Permanent','Permanent'),('Temporary','Temporary')]
        emp_name = models.ForeignKey(Employee)
        bill_type = models.CharField(max_length = 10,choices=bill_choices,verbose_name='Bill type')
        start_date = models.DateField(blank=True,verbose_name='Billing Start Date',null=True)
        end_date = models.DateField(blank=True,verbose_name='Billing End Date',null=True)

Now in admin page I need to show start_date and end_date field only if the user choose bill_choice as Temporary. How can i do that. Do i need to write a java-script for it if so how can i register the java script with admin page in django

Answer 1

This is the closest I got:

class BillingDetailAdmin(admin.ModelAdmin):
    class Media:
        js = ('app/js/code.js', )  # Django will resolve the static URL on its own

Then in the page, I found jQuery to be bound to grp.jQuery or django.jQuery (unless you include your own jQuery there's the one that comes with Django admin), then I listen on dropdown changes then show/hide inputs accordingly.
