How to customize the formset of InlineModelAdmin.
Purpose: I want to customize the fields in InlineModelAdmin because I want
to hide some fields.
My attempt:
class SKUInline(admin.TabularInline):
model = models.SKU
formset = modelformset_factory(models.SKU, fields=('values', 'price',))
@admin.register(models.Goods)
class GoodsAdmin(admin.ModelAdmin):
inlines = [
SKUInline,
]
