Question

我正在制作一个模型女巫有一个CommaSeparatedIntegerField我存储了一些图像的顺序，我从文件夹FolderField获取。

class Gallery(models.Model)
    […]
    folder = FilerFolderField(blank=False)
    order = models.CommaSeparatedIntegerField(max_length=300, blank=True)

现在，我正在寻找一种方法，可以在Django管理员中轻松更改此顺序（例如通过拖放）

P.S。我知道FilerFolderField尚未记录，可以删除，并且不推荐使用CommaSeparatedIntegerField。

Answer 1

正如e4c5的评论中所建议的那样，我大幅改变了我的命令。我现在有一个带有FilerFolderField的模型（仍未记录）和一个filesm.model.mmage的sortedm2m，其中包含所选文件夹中所有文件的自定义查询集。

models.py：

class Car(models.Model):
    …
    folder = filer.fields.folder.FilerFolderField(blank=False)
    images = SortedManyToManyField(filer.models.Image)
    …

admin.py：

class CarAdminForm(ModelForm):
class Meta:
    model = Car
    fields = '__all__'

def __init__(self, *args, **kwargs):
    super(CarAdminForm, self).__init__(*args, **kwargs)
    choices = []
    for i in self.instance.folder.files.all():
        i.__str__ = thumb_string
        choices.append(i)
    self.fields['images'].queryset = self.instance.folder.files.all()


class CarAdmin(admin.ModelAdmin):
    list_display = ['name']
    list_filter = ['created']

    def __init__(self, model, admin_site):
        super(CarAdmin, self).__init__(model, admin_site)
        self.orig_form = self.form

    def change_view(self, request, object_id, form_url='',     extra_context=None):
        self.form = CarAdminForm
        self.prepopulated_fields = {}
        self.exclude = []
        return super(CarAdmin, self).change_view(request, object_id)

    def add_view(self, request, form_url='', extra_context=None):
        self.form = self.orig_form
        self.prepopulated_fields = {"slug": ("name",)}
        self.exclude = ('images', )
        return super(CarAdmin, self).add_view(request)


class CategoryAdmin(admin.ModelAdmin):
    list_display = ['title', 'description']




admin.site.register(Car, CarAdmin)
admin.site.register(Category, CategoryAdmin)
