Question

我正在尝试将PageChooserPanel添加到“相关链接”模型中，并且未在管理员中显示。在迁移或加载页面时没有错误。这是代码：

sua_base / models.py：

STATE_CHOICE = ['state1', 'state2', 'state3']
state = sorted(STATE_CHOICE)
SPORT_CHOICE = ['basketball', 'football', 'cricket', 'hockey']


class Sports(models.Model):
    state = models.CharField(max_length=100, choices=state, default=state[0])
    team_members = models.IntegerField(required=True)
    sport = models.CharField(choice=SPORT_CHOICE, default=STATE_CHOICE[0])

app / models.py：

class RelatedLinks(models.Model):

    page = models.ForeignKey(
        'wagtailcore.Page',
        null=True,
        blank=True,
        on_delete=models.SET_NULL,
        related_name='+',
    )

    title = models.CharField(max_length=255, blank=True)
    url = models.URLField("Embed URL", blank=True)

    panels = [
        FieldPanel('title'),
        PageChooserPanel('page'),
        FieldPanel('url'),
    ]

    class Meta:
        abstract = True
        verbose_name = "Related Link"
        verbose_name_plural = "Related Links"

其他2个字段（from sua_base.models import WebPage, Section, RelatedLinks class SUAWebPage(WebPage): sidebar_content_panels = [ InlinePanel('related_links', label="Related Links") ] edit_handler = TabbedInterface([ ObjectList(content_panels, heading='Content'), ObjectList(sidebar_content_panels, heading='Sidebar'), ObjectList(WebPage.settings_panels, heading='Settings', classname="settings"), ObjectList(Page.promote_panels, heading='Promote'), ]) class Meta: verbose_name = "SUA Web Page" verbose_name_plural = "SUA Web Pages" class SUAWebPageRelatedLinks(RelatedLinks, Orderable): page = ParentalKey(SUAWebPage, related_name='related_links')和title）显示得很好，只是PageChooserPanel消失了。

Answer 1

之所以失败，是因为您在链接到的页面的page和ForeignKey中都使用了RelatedLinks的名称ParentalKey指向包含页面（在SUAWebPageRelatedLinks中）。您需要重命名其中之一。

g：PageChooserPanel未显示
