嗨，我有以下 Admin.py

from portfolio.models import LandingPage, Galleries
from django.contrib import admin

from mezzanine.pages.models import Page, RichTextPage, Link
from mezzanine.core.admin import DisplayableAdmin
from mezzanine.utils.urls import admin_url

class GalleriesInline(admin.StackedInline):
    model= Galleries.galleries.through

    list_display = ('galleries','thumb')
class PortfolioAdmin(admin.ModelAdmin):
    fieldsets = [
            (None,  {'fields':['gallerytitle']})
            ]
    inlines = [GalleriesInline]



admin.site.register(LandingPage, PortfolioAdmin)

这是我的模型.py

from django.db import models
from mezzanine.pages.models import Page
from mezzanine.galleries.models import Gallery, GalleryImage


class LandingPage(models.Model):

    gallerytitle = models.CharField(max_length=200)

    def __unicode__(self):
        return self.name

class Galleries(LandingPage):
    landingpage = models.ForeignKey(LandingPage, related_name='lan_page')
    #galleriesthumb = models.ForeignKey(GalleriesThumb)
    tagline = models.CharField(max_length=100)
    gallery = models.ManyToManyField(Gallery, related_name='gallerys')
    thumb = models.ManyToManyField(GalleryImage)

    def __unicode__(self):
        return self.name

当尝试通过管理员添加新的“LandingPage”时，我得到：

我正在尝试将管理员设置为显示画廊的所有实例，并选择一个画廊以便能够选择与画廊相关的 GalleryImage

如果这是一个愚蠢的问题，我很抱歉。我是新手，我正在努力解决这个问题，但我被困住了。
