特定用戶內容添加，編輯，刪除特定用戶的特定數據

Question

我開始組織一個項目，但有兩個主要模型是品牌和產品。

我將允許客戶在Django管理站點上登錄以編輯他們的品牌並添加，編輯和刪除他們自己的產品。

但是當編輯他們的產品時，表示客戶端只能夠添加，編輯刪除自己的產品;因此，例如，由於權限限制，他們的品牌名稱將在外鍵下拉菜單中被選中。從那裏他們可以重複添加品牌和刪除和編輯品牌的過程。

當前設置&問題

目前我有這種設置對於品牌我想順便說一下，只是一個客戶端只能看到自己的品牌來編輯。但對於產品，他們可以看到全部的產品，即使是不同的品牌（這不是我想要的）;當他們創造新產品時，他們必須從產品的下拉列表中進行選擇以符合（這不是我想要的）。我使用默認的Django權限，以及一些ModelAdmin方法。

# Register Models below 
admin.site.register(Brand, BrandAdmin) 
admin.site.register(Product, ProductAdmin) 

什麼是解決這個問題的解決方案？

Answer 1

class ProductAdmin(admin.ModelAdmin): 
    ... 
    def get_queryset(self, request): 
     ... 
     return qs.filter(brand__brand_name = request.user) 

希望這項工作。如果不是，請告訴我。
