I'm stuck with a Django project, I tried to add another app called login to make a login page but for some reason the page just redirects to the homepage except for the admin page
For example: 127.0.0.1:8000 will go to the homepage but 127.0.0.1:8000/login will also display the homepage even though I linked another template to it.
Here is my code:
main urls.py
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('portal.urls')),
url(r'^login/', include('login.urls')),
]
login urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^login/', views.index, name="login"),
]
login views.py
from django.shortcuts import render
def index(request):
return render(request, 'login/login.html')
portal urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^', views.index, name="portal"),
]
I see 2 problems here:
As #DanielRoseman mentioned above, the regular expression ^ matches anything, so you should change it to ^$.
When you use an include, the rest of the path after what the include matched is passed to the included pattern. You’ll want to use ^$ in your login urls.py too.
You don't terminate the portal index URL, so it matches everything. It should be:
url(r'^$', views.index, name="portal"),
In addition, if the regex is login/$ but you enter http ://server/login, then it won't match wheras http://server/login/ will.
You could try changing the regex to login/*$, which will match any number (even zero) / on the end of the url.
So http: //server/login, http: //server/login/, http: //server/login//// would all match.
Or if you want to be specific, login/{0,1}$ might work (though that regex syntax is from memory!)

in django urls without a trailing slash in the end i get this result "Page not found 404"
the same project and the same code in one pc i get different result.
this code is when i get the page without slash:
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
path('about', views.about, name='about'),
]
and this the same code but i should to add slash
from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name='index'),
path('about/', views.about, name='about'),
]
what i am waiting in the frontend its my views.py
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def about(request):
return HttpResponse('about page')
i am waiting for your help guys
This behaviour is controlled by the APPEND_SLASH setting. In the default setting APPEND_SLASH is set to True which means if the requested URL does not match any paths set in urls.py an HTTP redirect will issue to the same URL with a trailing slash.
Eg:
Assume a request to /foo.com/bar will redirect to /foo.com/bar/ in case the provided URL /foo.com/bar is an invalid URL pattern.
Documentation states that
Note that the redirect may cause any data submitted in a POST request to be lost.
The APPEND_SLASH setting is only used if CommonMiddleware is installed (see Middleware). See also PREPEND_WWW.
please read the documentation for further clarification.
So, I am not really lucky with latest django version tutorials, so I've had some problems with things that changed between some versions. One of this things is: althought I do exactly as I read/watch in the tutorials I always get the same result - all urls redirect to the same HTML page.
Here is my root urls.py
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^', include('theblog.urls')),
]
Here is my app urls:
from django.conf.urls import url, include
from .views import HomeView, ArticleDetailView
urlpatterns = [
url('', HomeView.as_view(), name='home'),
url('^article/<int:pk>', ArticleDetailView.as_view(), name='article-detail'),
]
For example, when I go to localhost:8000/articles/1 (or any other pk), it renders home.html (HomeView class) as if it was localhost:8000/.
Hope you can help me. Thanks!
There are two things wrong with your code.
url('^article/<int:pk>', ArticleDetailView.as_view(), name='article-detail'),
This will not work. If you want to use url. you can't use <int:pk>, you need to use a RegEx:
url("article/([0-9]+)/", ArticleDetailView.as_view(), name="article-detail")
Note that this will be deprecated in the future and if you are using django >=2.0 you should use path:
path("article/<int:article>/", ArticleDetailView.as_view(), name="article-detail")
However this will still direct you to the wrong view. django stops after the first URL pattern match.
Switch them around to fix that:
urlpatterns = [
url("article/([0-9]+)/", ArticleDetailView.as_view(), name="article-detail"),
# path("article/<int:article>/", ArticleDetailView.as_view(), name="article-detail"), # alternative with path instead of url
url('', HomeView.as_view(), name='home')
]
It may be due to this line
url('', HomeView.as_view(), name='home'),
Because url wraps re_path there may be some logic which will treat the blank regex string as a wildcard. Try changing it to '/'
url('/', HomeView.as_view(), name='home'),
So I am following a Django tutorial and I have reached the stage where I add my own URL patterns to the urls.py file.
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url((r'^webapp/', include('webapp.urls'))),
url(r'^admin/', admin.site.urls),
]
the problem is that when I run the server Django doesnt even search for the pattern. I'm not sure what I'm doing wrong here
webapp.urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.index, name='index'),
]
Make sure the directory structure is:
app
app
urls.py
webapp
urls.py
You write about a file named webapp.urls.py that is unusable by django
You pass wrong arguments for url().
Wrong:
url((r'^webapp/', include('webapp.urls')))
Right:
url(r'^webapp/', include('webapp.urls'))
I'm going through the polls Django tutorial and have searched for answers to this. So far:
I made sure I'm using the right directories. The main urls.py is in mysite/mysite/, the polls urls.py is in mysite/polls/urls.py.
Tried adding 'polls' to INSTALLED_APPS in the settings.py of mysite/mysite.
Am making sure that I am requesting 127.0.0.1:8000/polls and not 127.0.0.1:8000
I am using Python 3.4 and Django 1.9, same as the tutorial.
I am still receiving this message:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/polls
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
^polls/
^admin/
The current URL, polls, didn't match any of these.
mysite/mysite/urls.py
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^polls/', include('polls.urls')),
url(r'^admin/', admin.site.urls),
]
mysite/polls/urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^%', views.index, name='index'),
]
mysite/polls/views.py
from django.shortcuts import render
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, world")
In your polls/urls.py
change url(r'^%', views.index, name='index') to url(r'^$', views.index, name='index').
Also in your urls.py, you have route for 127.0.0.1:8000/polls/ and you request for 127.0.0.1:8000/polls . Notice the trailing slash.
So you should request to 127.0.0.1:8000/polls/ .
Add APPEND_SLASH = True in your settings.py file so that it would redirect 127.0.0.1:8000/polls to 127.0.0.1:8000/polls/ .
So i tried your Index view with your urls.py.
It works, the only thing different is in your "Request URL, you must request for - 127.0.0.1:8000/polls/%
changing your urls to
url('^/%', index) - polls URLs.py
url('^polls', include('polls.urls')) - project URLs
This will work.
I'm totally new to Django, and I'm trying to understand how does it work (I'm more used to PHP and Spring frameworks.
I have a project called testrun and inside it an app called graphs, so my views.py looks like:
#!/usr/bin/python
from django.http import HttpResponse
def index(request):
return HttpResponse("Hello, World. You're at the graphs index.")
then, in graphs/urls.py:
from django.conf.urls import patterns, url, include
from graphs import views
urlpatterns = patterns(
url(r'^$', views.index, name='index'),
)
finally, at testrun/urls.py:
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'testrun.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^graphs/', include('graphs.urls')),
url(r'^admin/', include(admin.site.urls)),
)
However, when I try to access http://127.0.0.1:8000/graphs/ I get:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/graphs/
Using the URLconf defined in testrun.urls, Django tried these URL patterns, in this order:
^admin/
The current URL, graphs/, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
What am I doing wrong that I can't get that simple message to be displayed in the browser?
To expand on my comment, the first argument to patterns() function is
a prefix to apply to each view function
You can find more information here:
https://docs.djangoproject.com/en/dev/topics/http/urls/#syntax-of-the-urlpatterns-variable
Therefore in graphs/urls.py you need to fix the patterns call like so:
urlpatterns = patterns('', # <-- note the `'',`
url(r'^$', views.index, name='index'),
)
