django - django-autocomplete-light django 1.8 管理员自定义模型表单

Question

我想将 OneToOne 字段的自动完成添加到 django-admin

class Banner(models.Model):
    product = models.OneToOneField(Product, null=True)

class BannerAdmin(admin.ModelAdmin):
    form = BannerForm

坚持https://django-autocomplete-light.readthedocs.org/en/stable-2.xx/tutorial.html?highlight=tutorial#tutorial -在所有以下步骤之后发生任何变化（“产品”的相同列表小部件.. .):

我做了什么：

1. 安装：D
2. 将“autocomplete_light”添加到 INSTALLED_APPS
3. 覆盖 admin/base_site.html（使用自定义加载器）
4. url(r'^autocomplete/', include('autocomplete_light.urls')), 到 urlpatterns
5. autocomplete_light_registry.py 带有模型Banner和search_fields=['product']，
6. 更新模型：

class BannerForm(autocomplete_light.ModelForm):
    class Meta:
        model = Banner
        fields = ['product', 'priority', 'image']
        autocomplete_fields = ['product']

我错过了什么？

Answer 1

以下解决了我的问题：

1. 在 INSTALLED_APPS 中的管理员之前

  INSTALLED_APPS = (
    'autocomplete_light',
    'django.contrib.admin',
  )

2. autocomplete_light_registry.py

class BannerAutocomplete(autocomplete_light.AutocompleteModelBase):
    model = Banner
    search_fields = ('name',)  # banner_obj.product.name
    choices = Product.objects.all()
    limit_choices = 20

    autocomplete_light.register(
        BannerAutocomplete,
        attrs={
            'placeholder': _(u'имя товара'),
            'data-autocomplete-minimum-characters': 1,
        },
    )

3. 为表单中的相关字段手动选择自动完成：

class BannerForm(autocomplete_light.ModelForm):
    class Meta:
        model = Banner
        fields = ['product', 'priority', 'image']
        autocomplete_names = {'product': 'BannerAutocomplete'}
