Wagtail/Weasyprint URLFetchingError /恢复/生成

Question

我正在做我的第一个django/wagtail项目，在那里我使用这模板来生成一份简历。我已经设法通过heroku发布了我的项目，并且我能够加载它。但是，当我想要按下"Get“时，我不知道如何处理错误URLFetchingError at /resume/generate。

下面您可以看到我的完整回溯以及我是如何设置我的urls.py文件的。任何关于如何解决这一问题的建议都将不胜感激。

urls.py

from django.urls import include, path
from django.contrib import admin

from wagtail.admin import urls as wagtailadmin_urls
from wagtail.core import urls as wagtail_urls
from wagtail.documents import urls as wagtaildocs_urls

from search import views as search_views

urlpatterns = [
    path('django-admin/', admin.site.urls),

    path('admin/', include(wagtailadmin_urls)),
    path('documents/', include(wagtaildocs_urls)),

    path('search/', search_views.search, name='search'),

]


if settings.DEBUG:
    from django.conf.urls.static import static
    from django.contrib.staticfiles.urls import staticfiles_urlpatterns

    # Serve static and media files from development server
    urlpatterns += staticfiles_urlpatterns()
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

urlpatterns = urlpatterns + [
    # For anything not caught by a more specific rule above, hand over to
    # Wagtail's page serving mechanism. This should be the last pattern in
    # the list:
    path("", include(wagtail_urls)),

    # Alternatively, if you want Wagtail pages to be served from a subpath
    # of your site, rather than the site root:
    #    path("pages/", include(wagtail_urls)),

    # Wagtail-resume
    path("resume/", include("wagtail_resume.urls")),
    #path("generate/", include("wagtail_resume.urls")),
]

Answer 1

正如注释所指出的，path("", include(wagtail_urls)),应该是列表中的最后一个模式，因为它捕获了与更具体的规则不匹配的所有内容--

path("resume/", include("wagtail_resume.urls")),

线是永远达不到的。你应该把它移到wagtail_urls线上。
