Django Inlining shows additional fields in the add dialog -


i wrote django 1.7.7 code:

class color(models.model):                                                               color = models.charfield(max_length=20, primary_key=true)                         def __unicode__(self):                                                                   return str(self.color)                                                        class pen(models.model):                                                                 label = models.charfield(max_length=20, primary_key=true)                            color = models.foreignkey('color')  class penadmin(admin.modeladmin):                                                        pass                                                                           class peninline(admin.tabularinline):                                                    model = pen                                                                       class coloradmin(admin.modeladmin):                                                      inlines = [peninline,]                                                            admin.site.register(pen, penadmin)                                                   admin.site.register(color, coloradmin)

i want know why when click on add color button in admin page, shows 3 pen fields in image below , how remove them specific dialog. i've tried both tabularinline , stackedinline , identical.

enter image description here

inlinemodeladmin extra's default value 3, can change extra = 0 in peninline declaration:

class peninline(admin.tabularinline):                                                    model = pen     = 0

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.inlinemodeladmin.extra

or @ https://stackoverflow.com/a/2228821/3033586

or remove coloradmin declaration , change last line admin.site.register(color)
