让 django-admin-sortable 和 django-parler 一起工作

Question

我有两个使用through table 的多对多关系模型

# models.py

class Item(TranslatableModel):
    name = models.CharField(max_length=100)  # this one is translatable

class Person(TranslatableModel):
    name = models.CharField(max_length=100)  # this one is translatable
    items = models.ManyToManyField(
        'Item',
        through='PersonItem',
    )


class PersonItem(Sortable):

    class Meta(Sortable.Meta):
        ordering = ['order']

    person = models.ForeignKey('Person')
    item = SortableForeignKey('Item')

但我无法在管理员中对Items 进行排序

# admin.py

class PersonItemInline(TranslatableTabularInline, SortableTabularInline):
    model = PersonItem
    form = PersonItemForm
    extra = 1

class PersonAdmin(TranslatableAdmin):
    form = PersonForm
    inlines = [
        PersonItemInline
    ]


admin.site.register(Person, PersonAdmin)

当我首先从translatable 继承时，我失去了排序功能。当我首先尝试从sortable 继承时，出现以下错误

NoReverseMatch 带有参数的“person_person_do_sorting”的反向 未找到“(239,)”和关键字参数“{}”。尝试了 0 个模式：[]

环境（python 3）： django==1.10.7、django-parler==1.6.5、django-admin-sortable==2.0.19

Answer 1

@most-wanted 确保继承顺序正确：

class PersonItemInline(SortableTabularInline, TranslatableTabularInline):
    ...
class PersonAdmin(SortableAdmin, TranslatableAdmin):
    ...

并像这样在 PersonAdmin 类中覆盖 change_form_template_extends：

class PersonAdmin(SortableAdmin, TranslatableAdmin):
    change_form_template_extends = 'admin/parler/change_form.html'
