url doesn't match with url file - django

Question

I'm trying to deploy an app, but I'm getting Page not found (404) error for my login template/view. But the same code works on localhost.
This is the error message:
The current URL, accounts/profile/profile.html, didn't match any of these.
URLs file:
urlpatterns = patterns('',
# Examples:
url(r'^$', 'survey.views.home', name='home'),
url(r'^survey/(?P<id>\d+)/$', 'survey.views.SurveyDetail', name='survey_detail'),
url(r'^confirm/(?P<uuid>\w+)/$', 'survey.views.Confirm', name='confirmation'),
url(r'^privacy/$', 'survey.views.privacy', name='privacy_statement'),
url(r'^admin/', include(admin.site.urls)),
url(r'^piechart/$', 'survey.views.piechart', name = 'chart_code.html'),
url('^accounts/', include('registration.urls')),
url('^accounts/login/$', 'survey.views.login'),
url('^accounts/auth/$', 'survey.views.auth_view'),
**url('^accounts/profile/$', 'survey.views.profile'),**
url('^accounts/logout/$', 'django.contrib.auth.views.logout'),
url(r'^map/$','survey.views.javamap', name = 'chart_code.html'),
url(r'^charts', 'survey.views.charts', name='charts'),
url(r'^login/$', 'django.contrib.auth.views.login'),
url(r'^accounts/auth/profile', 'survey.views.profile', name = 'profile.html'),
url(r'^profile', 'survey.views.profile', name = 'profile.html'),
url(r'^accounts/auth/results', 'survey.views.survey_name', name = 'results.html'),
url(r'^answer_survey', 'survey.views.answer_survey'),
url(r'^results/(?P<id>\d+)/$', 'survey.views.SurveyResults', name='results'),
)
The profile views:
#login_required
def profile(request):
user = request.user
if user.is_authenticated():
n_survey = Survey.objects.filter(user = user)
if n_survey:
print "*---------- str " + str(n_survey)
for survey in n_survey:
print "survey id " + str(survey.id)
n = len(n_survey)
print "n " + str(n)
return render(request, 'profile.html')
else:
print("*---------- sem surveys para print")
return HttpResponseRedirect('profile.html')
else:
msg = "Usuario ou senha digitados incorretamente"
return HttpResponseRedirect('home.html', {'msg': msg})
In localhost, the URL accounts/profile matches because django doesn't incluse profile.html at the end. How to solve this?

Answer 1

You are doing a redirect to a relative URL:
return HttpResponseRedirect('profile.html')
That means, if you are currently at /accounts/profile/, you will be redirected to /accounts/profile/profile.html. If you want to redirect to the view named profile.html, you can, for example, use the redirect shortcut:
from django.shortcuts import redirect
# ...
return redirect("profile.html")
Which is roughly equivalent to HttpResponseRedirect(reverse("profile.html")).
There is another problem in your url configuration: it contains some lines like this:
url(r'^charts', 'survey.views.charts', name='charts'),
There are two problems with this line
There is no slash at the end of the URL. It is better to be consistent and have a slash at the end of all URLs
There is no end-of-line special character $ at the end of the pattern. This means that many different URLs will match the pattern, for example /charts, /charts/foo, /chartsarecool and so on..
Better write
url(r'^charts/$', 'survey.views.charts', name='charts')
