我收到错误TemplateDoesNotExist

Question

我在wagtail admin中添加了一个应用程序到我的边栏，但是如果我点击它就会出现此错误

我的model.py:

class TeamRoosterTwo(models.Model):
    team_name = models.CharField(max_length=100, default="")
    team_logo = models.ForeignKey(
        'wagtailimages.Image',
        null=True, blank=True,
        on_delete=models.SET_NULL,
        related_name='+'
    )
    staff = StreamField([
        ('staff', CardsBlock(Staff(), icon="plus")),
    ], blank=True)
    spieler = StreamField([
        ('spieler', CardsBlock(Spieler(), icon="user")),
    ], blank=True)



    content_panels = [
        FieldPanel('team_name', classname="col12"),
        ImageChooserPanel('team_logo'),
        StreamFieldPanel('staff'),
        StreamFieldPanel('spieler'),
    ]

    def __str__(self):
        return self.team_name

我用以下代码创建了wagtail_hooks.py：

from wagtail.contrib.modeladmin.options import (
    ModelAdmin, modeladmin_register)
from . models import TeamRoosterTwo

class TeamRoosterModelAdmin(ModelAdmin):
    model = TeamRoosterTwo
    menu_label = 'Treichle Cup'
    menu_icon = 'group'
    menu_order = 200
    exclude_from_explorer = True

modeladmin_register(TeamRoosterModelAdmin)

您可能错过了将wagtail.contrib.modeladmin添加到INSTALLED_APPS：http://docs.wagtail.io/en/v1.13.1/reference/contrib/modeladmin/index.html#installation
