向现有项目中添加其他模板会出错 [英] Adding an additional template to an existing project errors out

问题描述

我上周发布了一些内容，但没有得到答案.我正在使用以下github项目来使用过滤器.我无法让其他模板正常工作.

解决方案

您需要在应用程序的URL中包括您的应用程序URL.

  urlpatterns = [url(r'^ $'，TemplateView.as_view(template_name ='home.html')，name ='home')，url(r'^ search/$'，FilterView.as_view(filterset_class = UserFilter，template_name ='search/user_list.html')，name ='search')，url(r'^ admin/'，include(admin.site.urls))，url(r'^ myapp/'，include('myapp.urls')，] 

您还应该从应用程序的网址中删除 admin 之类的网址，否则它们将在/admin/和/myapp/admin/.

  app_name ='myapp'urlpatterns = [url(r'^ results/$'，views.results，name ='results')，] 

建议(但不是必需)在应用程序的 urls.py 中设置 app_name .如果这样做，则在反转网址时必须使用它，例如'myapp:results'而不是'results'.

I posted something last week and I haven't been able to get an answer. I'm using the following github project for using filters. I'm having trouble getting any additional templates to work.

https://github.com/sibtc/simple-django-filter

When I attempt to add a new template to the project or view I get the following error when trying to navigate to search because the template has a reference to a new page called results,which the results of the filter will have a POST occur:

django.urls.exceptions.NoReverseMatch: Reverse for 'results' not found. 'results' is not a valid view function or patter
n name.

When trying to add the url for the view for results using the following, I still get the error above:

url(r'^results/$', views.results, name='results'),

I also include from . import views in the urls.py

I'm adding an empty view for results:

def results(request):


    return render(request, 'results.html', args)

I'm thinking it has to do something with how the directory structure of the simple filter app is setup and how i'm doing things.

I added the project URL below as well:

from django.conf.urls import url, include
from django.contrib import admin
from django.views.generic import TemplateView
from django_filters.views import FilterView
from mysite.search.filters import UserFilter

urlpatterns = [
    url(r'^$', TemplateView.as_view(template_name='home.html'), name='home'),
    url(r'^search/$', FilterView.as_view(filterset_class=UserFilter, template_name='search/user_list.html'), name='search'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^results/', include('app_name.urls')),

]

Here are is application urls.py

  from django.conf.urls import url, include
from django.contrib import admin
from django.views.generic import TemplateView
from django_filters.views import FilterView
from mysite.search.filters import UserFilter
from . import views



app_name = 'search'

urlpatterns = [
    url(r'^results/$', views.results, name='results'),
]

Added installed apps:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'mysite',
    'mysite.search',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'widget_tweaks',
]

Added directory structure:

解决方案

You need to include your applications URLs in the project's urls.

urlpatterns = [
    url(r'^$', TemplateView.as_view(template_name='home.html'), name='home'),
    url(r'^search/$', FilterView.as_view(filterset_class=UserFilter, template_name='search/user_list.html'), name='search'),
    url(r'^admin/', include(admin.site.urls)),
    url(r'^myapp/', include('myapp.urls'),
]

You should also remove the urls like admin from the application's urls, otherwise they will be available at /admin/ and /myapp/admin/.

app_name = 'myapp'

urlpatterns = [
    url(r'^results/$', views.results, name='results'),
]

It's recommended, but not required, to set app_name in the application's urls.py. If you do this, then you'll have to use it when reversing the URLs, e.g. 'myapp:results' instead of 'results'.
