Question

我的urlpatterns出了什么问题？

urlpatterns = [
    re_path(r'^dj-admin/', admin.site.urls),
    re_path(r'^admin/', include(wagtailadmin_urls)),
    re_path(r'^docs/', include(wagtaildocs_urls)),

    i18n_patterns(
        path(r'', include(wagtail_urls)),
        prefix_default_language = False
    )
]

错误：
？:( urls.E004）您的网址格式[（无：无）''＆gt;]无效。确保urlpatterns是path（）和/或re_path（）实例的列表。

据我所知，它等同于docs中的示例：

urlpatterns = [
    path('sitemap.xml', sitemap, name='sitemap-xml'),
]

urlpatterns += i18n_patterns(
    path('about/', about_views.main, name='about'),
)

顺便说一句：

In [1]: import django

In [2]: django.__version__
Out[2]: '2.0.5'

您已将i18n_patterns 放在模式列表中，但此函数本身会生成urlpatterns列表，而不是单个模式。这与您找到的文档不同。

使用连接：

urlpatterns = [
    re_path(r'^dj-admin/', admin.site.urls),
    re_path(r'^admin/', include(wagtailadmin_urls)),
    re_path(r'^docs/', include(wagtaildocs_urls)),
] + i18n_patterns(
    path(r'', include(wagtail_urls)),
    prefix_default_language = False
)

或使用*为函数调用添加前缀，以将所有元素合并到列表中：

urlpatterns = [
    re_path(r'^dj-admin/', admin.site.urls),
    re_path(r'^admin/', include(wagtailadmin_urls)),
    re_path(r'^docs/', include(wagtaildocs_urls)),

    *i18n_patterns(
        path(r'', include(wagtail_urls)),
        prefix_default_language = False
    )
]

这称为iterable unpacking，需要Python 3.5或更高版本。

文档使用+=扩充分配扩展 urlpatterns列表，这可能是一个很好的模式供您重复使用：

urlpatterns = [
    re_path(r'^dj-admin/', admin.site.urls),
    re_path(r'^admin/', include(wagtailadmin_urls)),
    re_path(r'^docs/', include(wagtaildocs_urls)),
]

urlpatterns += i18n_patterns(
    path(r'', include(wagtail_urls)),
    prefix_default_language = False
)

确保urlpatterns是path（）和/或re_path（）实例的列表
