現在、私はdjango/mezzanine/cartridge storeで作業しています。django catridge製品を拡張すると、Grapelli KeyErrorが管理者になります
models.py
class BaseProduct(Product):
cadfile = fields.FileField(upload_to="product", extensions=(".dwg",), blank=True, null=True)
pdffile = fields.FileField(upload_to="product", blank=True, null=True)
objects = SearchableManager()
search_fields = ("title", "description")
class Meta:
abstract = True
私の製品のすべては、私は次のように定義されてBaseProductモデルを作成したDRYに滞在するための努力で、CADファイルとPDFファイルを持っています
また、この基本製品タイプを次のようにサブクラス化する他の製品タイプもあります。
class CorniceProduct(BaseProduct):
cornice_picture = fields.FileField(upload_to="product", null=True, blank=True)
ceiling_projection = models.IntegerField(null=True, blank=True)
wall_height = models.IntegerField(null=True, blank=True)
class CeilingRoseProduct(BaseProduct):
width = models.IntegerField(null=True, blank=True)
height = models.IntegerField(null=True, blank=True)
これは行く、問題はこれがほとんどcartridge/shop/admin.pyファイルから導出され、メザニン管理エリアが付属しています限りのモデルとして機能します。
admin.py
option_fields = [f.name for f in ProductVariation.option_fields()]
product_fieldsets = deepcopy(DisplayableAdmin.fieldsets)
product_fieldsets[0][1]["fields"].insert(2, "available")
product_fieldsets[0][1]["fields"].extend(["content", "categories", "pdffile", "cadfile"])
product_fieldsets = list(product_fieldsets)
other_product_fields = []
if settings.SHOP_USE_RELATED_PRODUCTS:
other_product_fields.append("related_products")

product_list_display = ["admin_thumb", "title", "status", "available",
"admin_link"]
product_list_editable = ["status", "available"]
# If variations are used, set up the product option fields for managing
# variations. If not, expose the denormalised price fields for a product
# in the change list view.
if settings.SHOP_USE_VARIATIONS:
product_fieldsets.insert(1, (_("Create new variations"),
{"classes": ("create-variations",), "fields": option_fields}))
else:
extra_list_fields = ["sku", "unit_price", "sale_price", "num_in_stock"]
product_list_display[4:4] = extra_list_fields
product_list_editable.extend(extra_list_fields)
class CorniceProductAdmin(ProductAdmin):
cornice_additional_fieldsets = ("cornice_picture", "ceiling_projection", "wall_height")
fieldsets = product_fieldsets
fieldsets.append((_("Cornice specific"), {
"fields": tuple(cornice_additional_fieldsets)
}))
admin.site.register(CorniceProduct, CorniceProductAdmin)
class CeilingRoseProductAdmin(ProductAdmin):
rose_additional_fieldsets = ("width", "height")
fieldsets = product_fieldsets
#del fieldsets[4]
fieldsets.append((_("Ceiling Rose specific"), {
"fields": tuple(rose_additional_fieldsets)
}))
exclude = ('cornice_picture', 'ceiling_projection', 'wall_height',)
admin.site.register(CeilingRoseProduct, CeilingRoseProductAdmin)
私は、私は次のエラーを取得するceilingroseproductを編集するには、adminエリアに行く：

I はは、del fieldsets [4]行にumcommentingすることで修正しましたが、これは非常にハッキーなようで、本当にやりたくない製品タイプごとにこのレベルの上書きが必要です。
