Re: NoReverseMatch error message - Please help
Sometimes the error can be from your url.py or even views.py and also make
sure no typo. Check each on e of the above carefully. Hopefully you might
see the bug.
Cheers

Re: NoReverseMatch error message - Please help
Thanks Ryan.
I've just tried that, but I still get an error message.
By the way, is it definitely .id and not _id? I've seen both, and Django docs
says: 'Behind the scenes, Django appends "_id" to the field name to create its
database column name, which makes me wonder if it might be _id.
Incidentally, I've also tried amending the relevant URL path to
path('add_comment/', views.add_comment, name='add_comment') -
with underscore and with a dot before the id - but that doesn't work.

Re: NoReverseMatch error message - Please help
Based on the rest of your template from the github link, looks like:
{% url 'nowandthen:add_comment' image.id %}
...should instead be:
{% url 'nowandthen:add_comment' p.image.id %}

Trailing slashes are part of the path, so "/foobar/" is not the same as
"/foobar".
Hopefully that should give you a hint to what is most likely the cause
of your problem.

RE: Django Tutorial: "NoReverseMatch" Error
It looks like you have a typo:
urlpatterns = [
# ex: /polls/
path('', views.IndexView.as_view(), name='index'),
# ex: /polls/5/
# the 'name' value as called by the {% url %} template tag
path('/', views.DetailView.as_view(), name='detail'),
# ex: /polls/5/results/
path('/vote/', views.vote, name='vote'),
]
The red line should probably have this path:
/results/

Django Tutorial: "NoReverseMatch" Error
Hello, everyone! I have run into a problem I cannot figure out. I have
spent days searching online and trying different things in my code, but I
cannot figure out where this problem is stemming from. I would truly
appreciate any insights.
Admittedly, I am scrub enough that I'm not even sure of all the code I
should include, so if I should include anything else, please let me know!

Re: NoReverseMatch error raise when adding a new entry in django admin
Hi Weifeng,
I think the problem is here:
django.urls.exceptions.NoReverseMatch: Reverse for
'nmm_tokenservice_userprofile_change' with arguments '('',)' not found. 1
pattern(s) tried: ['admin/nmm_tokenservice\\/userprofile\\/(?P.+
)\\/change\\/$']
By all the Django is saying, you're trying to reverse the URL for
`mm_tokenservice_userprofile_change` passing an empty string as args; but
your regex por it requres an `object_id` that must have at least 1
character (that's what `.+` means). So, because you're passing no
parameters, it can't resolve the URL properly.
You *need* to pass the object_id, as per your URL specification, on your
reverse.
Hope that helps.

Re: NoReverseMatch Error using Django + Haystack + Elasticsearch
Thank you for your time, Constantine.
I gave up on following this path.
I threw away everything that I did on this matter, and I followed the steps
of this link: http://django-haystack.readthedocs.io/en/v2.5.0/tutorial.html
It took me some time to understand, but now it is working fine.
Thank you.

Re: NoReverseMatch Error using Django + Haystack + Elasticsearch
Hi Aline,
I did not use Haystack but I am using ElastickSearch.
I carefully read you post on StackOverflow and see that search form returns
author of the post without `pk` key defined.
Did you check what is returned by ElastickSearch?
May be your SearchForm returns exactly what Elastick stores in its index? I
mean that post returned by SearchForm not the same as Post model? It can be
dictionary or something?
Sorry I do not have time to build test app to check my idea.
You can easily set up a break point and check what are the posts inside
your `post_search` view function.
Regards,
Constantine C.

NoReverseMatch Error using Django + Haystack + Elasticsearch
Hello everybody,
I am having a issue using Django + Haystack + Elasticsearch to perform a
website search.
I made a question on StackOverflow, but I had no satisfatory answer.
The problem is in this line:
by {{ post.author
}}
post.author.pk works well when called by several views, but it is not
resolved when called by the search.
There is another way to get the pk of the author of the post?
The link of the StackOverflow question:
http://stackoverflow.com/questions/40033039/noreversematch-error-using-haystack-elasticsearch
Can someone help me? Please explain in details, because I am new in Django,
and in haystack, elasticsearch...

Re: NoReverseMatch error in django 1.8
Hello,
the bookp route requires a user and a book_id parameter. Unless you supply
that, your {% url %} tag won't match.

Re: NoReverseMatch error
You were right Vijay. I worked this out. I needed to set type and state
via the context as follows:
def get_context_data(self, **kwargs):
context = super(TestFlow, self).get_context_data(**kwargs)
context.update({'type': self.kwargs['type'], 'state':
self.kwargs['state']})
return context
... then reference type and state in the url template tag:

I think you need to pass the "type" and "state" values in the {% url ... %}

It looks like you have in polls/views.py whitespace in reverse function
("polls: results"), try without it ('polls:results").

NoReverseMatch error when following Django Tutorial
Dear every one,
I am new to Python and Django and am following the Tutorial to start my
first site. But I am getting an error of NoReverseMatch error when vote. It
should be redirected but error below happened.

Re: NoReverseMatch error on redirect
I figured it out. I had a namespaced url so it needed:
return HttpResponseRedirect(reverse('requestform:registrant_add',
kwargs={'app_id': obj.id}))

NoReverseMatch error on redirect
I have a mulit-page form I am building. I get the start page to enter the
data for the application, validate and save. When I try using reverse to
move to the next page I get this error:
NoReverseMatch at /requestform/start/Reverse for 'registrant_add' with
arguments '()' and keyword arguments '{'app_id': 11}' not found.
I have this url in my urls.py
url(r'^step1/(?P\d+)/$, RegistrantCreate.as_view(),
name="registrant_add"),
I am trying to call the view this way:
class ApplicationCreate(CreateView):
model = Application
form_class = ApplicationForm
slug_field = 'created_by'
template_name = 'requestform/start_form.html'
@method_decorator(login_required)
def dispatch(self, *args, **kwargs):
return super(ApplicationCreate, self).dispatch(*args, **kwargs)
def form_valid(self, form):
obj = form.save(commit=False)
obj.created_by = self.request.user
obj.created = datetime.datetime.today()
obj.modified = datetime.datetime.today()
obj.save()
return HttpResponseRedirect(reverse('registrant_add',
kwargs={'app_id': obj.id}))
Why doesn't django recognize the named url 'registrant_add' and redirect to
it?

This urlconf includes other urlconfs, trace the includes down from the top level and verify that this urlconf that your url is being defined in is actually included in the project. A simple way of doing this is ensuring that the view is available (and runs) if you directly go to that url. This is not necessarily meant to find anything, it is just verifying that everything is actually set up as you think it is.

Re: Yet Another NoReverseMatch Error
Oh sorry I wasn't clear. The first time I typed the patterns function call out.
So in other words, the %s was in there all along. I just misrepresented it in
my question. Things are failing even with the correct call and have been all
along.
Could you provide more details about how I can double-check the urlconf and
follow the includes down?
Thanks.

Does that make it work or does it still fail to reverse? I'm running
out of trouble shooting ideas - double check that the urlconf is
actually being used - start at the project level urlconf, and follow
the includes down.

Good catch. That was a typo. Let me cut and paste directly:
urlpatterns = patterns("apps.popular_keywords.views",
url("^%skeyword/(?P.*)%s$" % _slashes,
"matching_items_list", name="matching_items")

Perhaps I should try some of your coffee.

I hadn't had my coffee when I first saw this. This isn't a valid string format:
"^%keyword/(?P.*)%s$"
Probably just missing a 's' from the first format specifier, eg '^%skeyword…'.
Does it work correctly if you fix the format string?

Yet Another NoReverseMatch Error
I have an app within my project called popular_keywords.
Within *urls.py* I have this:
*urlpatterns = patterns("apps.popular_keywords.views",*
* url("^%keyword/(?P.*)%s$" % _slashes,
"matching_items_list", **name="matching_items")*
*)*
Within *views.py* I have this function:
*def matching_items_list(request, keyword=None,
template="popular_keywords/keyword_matched_list.html")*
In my template I have this:
**
*
*
*
*
The problem is when I view my page I find this:
*NoReverseMatch at /*
*Reverse for 'matching_items' with arguments '()' and keyword arguments
'{u'keyword': 'Cake'}' not found.*
*
*
I thought I had my bases covered, but as a Django noob, I would appreciate help
on whatever silly thing I missed. Please let me know if I need to provide more
information.
Thanks.

Sorry, it's {% load url from future %}, not import. Brain misfired and put
Python word in place of Django template language.

Note that will work for 1.4 but it's doing things the old way, and that
will break in 1.5. Much better to add {% import url from future %} and have
code that will continue to work with the next release of Django. Removing
the quotes is not the best approach at this time.

This is not a typo in the tutorial. The {% url %} variant is a faily recent
update to the current development level of the online docs. It was added
in order to show in the tutorial best practices: url reversal by name
rather than hard-coding url paths in the template. However, it uses the {%
url %} tag syntax that is correct for the upcoming Django release, 1.5. In
order for that syntax (specifically, the quotes around polls.views.vote) to
work in the 1.4 released version, the template would also have to include
{% import url from future %}. This "from future" import is not necessary in
the current development level of code, so was not included when this change
to demonstrate how to use {% url %} was added to the tutorial development
level. However it seems that many many many people are running through the
development-level doc with the 1.4- released level code, so perhaps we
should add a note here (or more prominently elsewhere) to please be sure
you run through the online version of the tutorial that matches the level
of code you are running.

NoReverseMatch error and serializers
Hello,
I have two local repos. The only difference between them is their DBs.
I'm trying to copy some tables from one DB to another via XML-RPC and
serializers.
I call my XML-RPC method from the shell. It returns a str
(serializer). Then I'm trying to deserialize that string:
for x in serializers.deserialize("xml", mydata):
x.save()
But I get a NoReverseMatch error.
I've already checked my URLconf. Patterns look fine.
I've also read that it can be connected with encoding (if you're using
MySQL). But I'm using SQLite.
How to get rid of this error?
Regards

Re: NoReverseMatch Error
Hi,
Look at this:
https://docs.djangoproject.com/en/dev/topics/http/urls/#reverse
`viewname` is incorrect in your app you must use 'poll_results'
instead of 'polls.views.results'

There seem to be a few confusions here. The arguments to a view are
those elements that are passed in the URL itself and extracted via the
urlconf regex. It is possible to insert extra arguments into the call
to the view by hard-coding them in the urlconf, as I think you are
trying to do with your `kwargs = {}`, but then there is no way of
specifying these dynamically - because the urlconf is matched against
the URL.
Next, what HttpResponseRedirect does - as the name implies - is send a
response to the browser, with an HTTP status code telling the browser
to request another URL, plus a Location header telling it what that
URL should be. So, again, any dynamic arguments you pass in (eg via
reverse) have to be things you can actually put into a URL.
So it isn't possible to arbitrarily insert the queryset as the
argument to reverse, as you attempt here, because there is no way to
insert that queryset into the URL in the redirect and extract it from
there in the urlconf.
Instead, you need to think about approaching this from a different
angle. If you want to preserve a queryset across requests, you will
need to save it somewhere - the session could be ideal for this.

NoReverseMatch error when attempting to spawn an intermediate window from an admin action
I am having trouble with learning to use httpresponseredirect and
reverse.
I am trying to generate an admin action on a selection of a list of
items. The purpose is to generate an intermediate window that can be
used to select a new
status for all the objects,
The admin action shows up in the pulldown menu on /admin/items/item.
However, once clicked, I get the following error: NoReverseMatch at /
admin/items/item/
Any advice would be greatly appreciated, I have been pounding me head
for a day or so on this. I am certainly a novice, so this is likely
to be a very newbie misunderstanding.
Many thanks,
Guy

If c is a bit of information that has to be returned by get_absolute_url, then it has to go in the URL somewhere.

'c' is not supposed to be visible in the URL itself. A person is only supposed to see /a/b/ when accessing the model's page. The thing is that I'm actually using the same URL pattern for the pages of two different models (not my decision, ugh!). 'c' is actually storing the model type. If 'c' is None, as when the URL is being accessed directly, I'd determine the model type in the view another way (I go through hoops, but it's possible). However, if I have a chance to use one of the model's get_absolue_url methods, I want to specify the model's type in 'c' so that the view knows what model it's working with at the start. Except that Django doesn't like my optional argument. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Optional URL argument from model's get_absolute_url causing NoReverseMatch error
I want to have a model view with an optional argument that's specified
by the model's get_absolute_url. This argument is None if the model's
page is accessed by the user typing in the URL in his browser, while
the argument is set to some value if the model's page is accessed by
clicking on a link such as the "View on site" button in the admin
site.
This is what I came up with first:
The model:
class MyModel(models.Model):
...
@models.permalink
def get_absolute_url(self):
return ('mymodels.views.model_view', (),
{ 'a': self.some_field,
'b': self.another_field,
'c': something_else_again } )
The URLConf:
(r'^(?P[-\w]+)/(?P[-\w]+)/$', 'model_view')
The view:
def model_view(request, a, b, c = None):
if c:
# Do something
else:
# Do something else
Accessing the model's page by just typing in a URL works (where c is
None). However, accessing the model's page by, say, clicking "View on
site" in the admin (where c should be set to the model type's ID)
gives me this NoReverseMatch error:
NoReverseMatch at /admin/r///
Reverse for '' with arguments '()' and
keyword arguments '{'a': u'something', 'b': u'something-else', 'c':
'something-else-again'}' not found.
Exception location: C:\Python26\lib\site-packages\django\core
\urlresolvers.py in reverse, line 291
What is the proper way to introduce optional arguments here?

Re: NoReverseMatch error during Django 1.0 tutorial
return HttpResponseRedirect(reverse
('mysite.polls.vews.results', args=(p.id,)))
As you see, there is a mistake in "vews".
return HttpResponseRedirect(reverse
('mysite.polls.views.results', args=(p.id,)))
Now it should work :)

NoReverseMatch error during Django 1.0 tutorial
Hello,
I am still working on the Django 1.0 tutorial (http://
docs.djangoproject.com/en/1.0/intro/tutorial04/) and
got the following error after voting on my poll ( which simply makes a
call to the Django reverse function which is supposed to give control
to my results function in polls.views).
The error is the following:
NoReverseMatch at /polls/1/vote/
Reverse for 'mysite.polls.vews.results' with arguments '(1,)' and
keyword arguments '{}' not found.
and my views.py is the following:
from mysite.polls.models import Choice, Poll
from django.shortcuts import get_object_or_404, render_to_response
from django.core.urlresolvers import reverse
from django.http import HttpResponseRedirect
# ...
def vote(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
return render_to_response('detail.html', {
'poll': p,
'error_message': "You didnt select a choice.",
})
else:
selected_choice.votes += 1
selected_choice.save()
return HttpResponseRedirect(reverse
('mysite.polls.vews.results', args=(p.id,)))
def results(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
return render_to_response('results.html', {'poll': p})

Any body got this NoReverseMatch problem fixed?. If so please point me to that. The patch over here http://code.djangoproject.com/attachment/ticket/4409/4409.patch is also not working for me .
