字段feincms内容类型上的FilteredSelectMultiple小部件

Question

我在FeinCMS中有自定义内容类型。

class DownloadsContent(models.Model):
    title = models.CharField(max_length=200, verbose_name=_('title'))
    files = FileManyToMany(verbose_name=_('files'))

'files'字段是一个很多人只显示.doc和.pdf文件：

class FileManyToMany(models.ManyToManyField):
    def __init__(self, to=MediaFile, **kwargs):
        limit = {'type__in': ['doc', 'pdf']}
        limit.update(kwargs.get('limit_choices_to', {}))
        kwargs['limit_choices_to'] = limit
        super(FileManyToMany, self).__init__(to, **kwargs)

直到现在一切正常。添加此内容类型时，它会显示所有文件。

但是如何在我的内容类型中使用FilteredSelectMultiple小部件？像：

Answer 1

实际上，实现这一目标的更简单方法是：

class DownloadContentInline(FeinCMSInline):
    filter_horizontal = ['files']


class DownloadContent(models.Model):
    feincms_item_editor_inline = DownloadContentInline

Answer 2

在我自己的模型字段类FileManyToMany中，添加“def formfield（self，...）” 添加小部件

from django.db import models
from feincms.module.medialibrary.models import MediaFile

class FileManyToMany(models.ManyToManyField):
    def __init__(self, to=MediaFile, **kwargs):
        limit = {'type__in': ['doc', 'pdf', 'xls']}
        limit.update(kwargs.get('limit_choices_to', {}))
        kwargs['limit_choices_to'] = limit
        super(FileManyToMany, self).__init__(to, **kwargs)

    def formfield(self, **kwargs):
        from django.contrib import admin
        defaults = {'widget': admin.widgets.FilteredSelectMultiple('vebose_name', False)}
        defaults.update(kwargs)
        return super(FileManyToMany, self).formfield(**defaults)
