使django-管理-可排序和django-parler一起工作

Question

我有两个使用through表具有多到多关系的模型。

# 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')

但是我无法在管理中对Item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，我就失去了排序功能。当我首先尝试从sortable继承时，我有以下错误

NoReverseMatch反向的'person_person_do_sorting‘与参数'(239，)’和关键字参数'{}‘没有找到。0已尝试的模式：[]

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

Answer 1

@most-希望确保输入顺序是正确的：

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

并在这样的change_form_template_extends类中重写PersonAdmin：

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