Django 在管理页面中显示一对多关系

Question

数据库示例：

class Brand(models.Model):
  brand_name = models.CharField(max_length=30


class Model(models.Model):
  brand = models.ForeignKey(Brand)
  model_name =  models.CharField(max_length=30)

现在在管理员中

admin.site.register(Brand)

class ModelAdmin(admin.ModelAdmin):
  list_display = ['brand', 'model_name']
  fields = ['model_name', 'brand']
admin.site.register(Model, ModelAdmin)

如何在 BrandAdmin 页面中显示与一个品牌关联的所有型号？ 就目前而言，“品牌”页面仅显示品牌，不显示与其关联的任何型号。

Answer 1

嗯，你最好的选择是django inlines

#admin.py    

class ModelAdmin(admin.ModelAdmin):
  list_display = ['brand', 'model_name']
  fields = ['model_name', 'brand']

class ModelInline(admin.TabularInline):
    model = Model

class BrandAdmin(admin.ModelAdmin):
    model = Brand
    inlines = [
        ModelInline,
    ]


admin.site.register(Brand, BrandAdmin)
admin.site.register(Model, ModelAdmin)
