I'm having problems with my URL paths.
Whenever I remove -- path('<query>/follow', views.follow, name='follow') -- everything works fine. When I include it, the page with the link on it reveals 'Reverse for 'follow' with no arguments not found' though I can manually type the follow path into the URL and it succeeds. Why is this and how can I fix it?
html
Follow
urls.py
urlpatterns = [
path('', views.explore, name='explore'),
path('happening/profile/', views.profile, name='profile'),
path('happening/', views.happening, name='happening'),
path('home/', views.home, name='home'),
path('home/likes/', views.likes, name='likes'),
path('<query>/follow', views.follow, name='follow'),
path('<query>/', views.profpage, name='profpage'),
]
views.py
def profpage(request, query):
obj = User.objects.filter(username=query)
if not obj:
attempt = {'user':query}
return render(request, 'error.html', attempt)
try:
obj2 = reversed(get_list_or_404(Comments, user=query))
except:
obj2= {}
try:
obj3 = get_list_or_404(Comments, user=query)
except:
obj3 = {}
like_dict={}
for x in obj3:
likes = x.likes.all().count()
like_dict[int(x.id)] = int(likes)
img = UserProfile.objects.filter(user__username=query)
for x in obj:
obj = x
for x in img:
img=x
content = {'obj': obj,
'img':img,
'info':obj2,

return render(request, 'profpage.html', content)

From my crop crop_prediction view I am trying to redirect it to 'http://localhost:8000/Efarma/crop_detail/' page but instead of this it render the current html page ,the home page which is also the starting page of this website.
Some error is showing in my console '[26/Apr/2022 22:31:29,457] - Broken pipe from ('127.0.0.1', 62868)' but I have no idea what is it.
To go to crop_detail page i have to manually put it in search box.
urls.py:-

from .import views
urlpatterns = [
path('', views.home),

data = np.array([[N, P, K, temperature, humidity, ph, rainfall]])
print(temperature, humidity, "--------kkk-------")

Thank you in advance,

Include pk in your url.
Change your url like this,
url(r'(?P<pk>\d+)/$', views.index, name='index'),
instead of,
# /batches/
url(r'^$', views.index, name='index'),
OR,
if you are not passing pk to views then remove pk from index view as showned below.
def index(request):
all_Batches = Batches.objects.all()
html = ''
for batch in all_Batches:
url = '/batches/' + str(batch.id) + '/'
html += '' + str(batch.BatchNumber)+ '<br>'
return HttpResponse(html)
There are two arguments for the index view. The URL that you have written only gives request. You must give pk as an input just like the detail URL
Your url /batches/ has no parameter. So,
Your index view should be
def index(request):

I get an HTTP 410 error when invoking the following Django View:
>>> views.py:
class ReopenMilestoneView(
dj_auth_mixins.LoginRequiredMixin, dj_views.RedirectView
):
pattern_name = 'bibliotheka_dashboard'
def dispatch(self, request, *args, **kwargs):
print('DISPATCH BEGIN')
instance = project_models.Milestone.objects.get(pk=kwargs['pk'])
instance.state = project_models.STATE_OPEN
instance.save()
print('DISPATCH END')
return super(ReopenMilestoneView, self).dispatch(
request, *args, **kwargs
)
def http_method_not_allowed(self, *args, **kwargs):
print('HTTP NOT ALLOWED BEGIN')
try:

print('REDIRECT END, result = ' + str(result))
url = urlresolvers.reverse('bibliotheka_dashboard')
url2 = urlresolvers.reverse(self.pattern_name)
print('REDIRECT END, URL_resolved = ' + str(url))
print('REDIRECT END, pattern_name = ' + str(self.pattern_name))

return result

),
url(
r'^milestone/(?P<pk>[\w-]+)/dashboard/$',
project_views.MilestoneDashboard.as_view(),
name='milestone_specific_dashboard'
),
...
I added prints through the three methods form "RedirectView" that are mentioned in the Django documentation as part of the regular workflow (django).
Dispatch is properly executed but, when resolving automatically the "pattern_name", "RedirectView" fails... manually resolving it, solves the problem.
DISPATCH BEGIN
DISPATCH END
REDIRECT BEGIN
REDIRECT END, result = None
REDIRECT END, URL_resolved = /
REDIRECT END, pattern_name = bibliotheka_dashboard

Gone: /prj/milestone/2/reopen/
[12/Jul/2017 13:28:34] "GET /prj/milestone/2/reopen/ HTTP/1.1" 410 0
I have used "RedirectView" before but I have never got this error, any ideas? Django is not returning a lot of info back...
My URLs are defined as follows:
from django.conf.urls import url, include
from django.conf.urls import static as dj_static
from django.contrib import admin
from bibliotheka import settings as bibliotheka_settings
from documentation.views import project as project_views
urlpatterns = [

]
if bibliotheka_settings.DEBUG:
urlpatterns += dj_static.static(
bibliotheka_settings.MEDIA_URL,
document_root=bibliotheka_settings.MEDIA_ROOT
)
I am trying to redirect to "/" with the problematic views.
Django is failing to reverse milestone_dashboard. In Django <= 1.11, it silences the NoReverseMatch, and returns a 410 response.
This behaviour has been changed in Django 2.0 (see ticket 26911), so Django will no longer silence the exception.
When you use pattern_name, Django tries to reverse with the same args and kwargs. You do not want this, as you are redirecting from a url containing the pk to a url that does not have any arguments.
You can set url with reverse_lazy:
from django.urls import reverse_lazy
class ReopenMilestoneView(RedirectView):
url = reverse_lazy('bibliotheka_dashboard')
I am getting error : 'str' object has no attribute 'method' . See my code below :
#csrf_exempt
def completepayment(request):
varerr =''
plist = []
if request.method == 'POST':
try:
nid = request.POST['txnref']
except MultiValueDictKeyError:
varerr ="Woops! Operation failed due to server error. Please try again later."
return render(request, 'uportal/main.html', {'varerr':varerr})
# Fetching member details
trym = Transactions.objects.get(TransRef=nid)
amount = trym.Amount
famt = int(amount * 100)
product_id = 48
salt = '4E6047F9E7FDA5638D29FD'
hash_object = hashlib.sha512(str(product_id)+str(nid)+str(famt))
hashed = hash_object.hexdigest()
url = 'https://bestng.com/api/v1/gettransaction.json?productid=pdid&transactionreference=nid&amount=famt'
raw = urllib.urlopen(url)
js = raw.readlines()
#js_object = simplejson.loads(js)
res = simplejson.dumps(js)
for item in res:
rcode = item[0]
#rdesc = item[1]
#preff = item[2]
thisresp = completepayment(rcode)
plist.append(thisresp)
else:
varerr ="Woops! Operation failed due to server error. Please try again later."
return render(request, 'uportal/main.html', {'plist':plist, 'varerr':varerr, 'completepayment':'completepayment'})
In summary I am trying to accept and use HTTP POST value from an external API. Value is showing when I inspect element but DJANGO not retrieving. Please help.
Here is my urls.py
from django.conf.urls import patterns, url
from views import *
from django.views.generic import RedirectView
urlpatterns = patterns('myproject.prelude.views',
# Home:
url(r'^$', 'home', name='home'),

url(r'^uportal/ugreg/proceedpayment/$', RedirectView.as_view(url='https://bestng.com/pay'), name='remote_admin'),
url(r'^uportal/ugreg/completepayment/$', completepayment, name='completepayment'),
Thank you
It appears that your problem is that request is an str object rather than a request object.
Please produce urls.py and views.py.
For readability, let’s rewrite the part below:
url = 'https://bestng.com/api/v1/gettransaction.json'
params = '?productid={product_id}&transactionreference={nid}&amount={famt}'
raw = urllib.urlopen(url + params.format(**locals()))
Or even, like so:
url = 'https://bestng.com/api/v1/gettransaction.json'
params = '?productid={product_id}&transactionreference={nid}&amount={famt}'
request = url + params.format(**locals())
raw = urllib.urlopen(request)
Also, the try block is not what I would use. Instead, I would use the get method of the POST dict and return a flag value:
nid = request.POST.get('tnxref', False)
I am unable to reproduce the error you are getting. With a slightly different project-level urls.py (very simplified), the ‘completepayment’ view works fine for me. Here is urls.py.
from django.conf.urls import patterns, url
from app.views import completepayment
# The app is simply called app in my example.
urlpatterns = patterns('',
# I remove the prefix
url(r'^uportal/ugreg/completepayment/$', completepayment, name='completepayment'),
)
# This last parenthesis might be missing in your code.
So this is in my urls.py
from django.conf.urls import patterns, include, url
from v1_1 import views
urlpatterns = patterns('',
url(r'', include('social_auth.urls')),
url(r'^$', views.fblogin), ### LINE1
url(r'^logged-in/$', 'v1_1.views.fb_loggedin'), ### LINE2
)
And it results in error because of LINE1. It (the same code) used to work some time back. If i change LINE1 to url(r'^$', 'v1_1.views.fblogin'), it works fine... i am unable to understand the problem :/
