如何在 django admin 中自定义多对多内联模型

我正在使用管理界面来查看发票和产品。为了简单起见，我已将产品设置为发票内联，因此我将在发票表单中看到相关产品。正如您所看到的，我使用的是多对多关系。

在 models.py 中：

class Product(models.Model):
    name  = models.TextField()
    price = models.DecimalField(max_digits=10,decimal_places=2)

class Invoice(models.Model):
    company  = models.ForeignKey(Company)
    customer = models.ForeignKey(Customer)
    products = models.ManyToManyField(Product)

在 admin.py 中：

class ProductInline(admin.StackedInline):
    model = Invoice.products.through

class InvoiceAdmin(admin.ModelAdmin):
    inlines = [FilteredApartmentInline,]
admin.site.register(Product, ProductAdmin)

问题是 django 将产品显示为下拉菜单表（每个关联产品一个）。每个下拉列表包含列出的所有产品。因此，如果我有 5000 个产品，其中 300 个与某个发票相关联，django 实际上会加载 300x5000 个产品名称。而且桌子也不美观。

我不需要通过发票表格更新产品。如何更改它以便它仅在内联表中显示产品名称？我应该覆盖哪种形式，以及如何覆盖？

I'm using the admin interface to view invoices and products. To make things easy, I've set the products as inline to invoices, so I will see the related products in the invoice's form. As you can see I'm using a many-to-many relationship.

In models.py:

class Product(models.Model):
    name  = models.TextField()
    price = models.DecimalField(max_digits=10,decimal_places=2)

class Invoice(models.Model):
    company  = models.ForeignKey(Company)
    customer = models.ForeignKey(Customer)
    products = models.ManyToManyField(Product)

In admin.py:

class ProductInline(admin.StackedInline):
    model = Invoice.products.through

class InvoiceAdmin(admin.ModelAdmin):
    inlines = [FilteredApartmentInline,]
admin.site.register(Product, ProductAdmin)

The problem is that django presents the products as a table of drop down menus (one per associated product). Each drop down contains all the products listed. So if I have 5000 products and 300 are associated with a certain invoice, django actually loads 300x5000 product names. Also the table is not aesthetic.

I don't need the products to be updatable via the invoice form. How can I change it so that it'll just display the product's name in the inline table?
Which form should I override, and how?
