Selenium test URL not found in Django
I'm new to Selenium and I'm getting "URL not found" error during a test. It's kinda strange since everything is working in my production evnviroment. I tried to replicate my production DB in my test enviroment but I still get the same error. I was just improving the Tutorial project of Django documentation v. 1.11. Here is my models.py: class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') def __str__(self): return self.question_text def was_published_recently(self): now = timezone.now() return now - datetime.timedelta(days=1) <= self.pub_date <= now class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.PositiveIntegerField(validators=[MinValueValidator(0)], default=0) def __str__(self): return self.choice_text Here is the urls.py : app_name = 'polls' urlpatterns = [ url(r'^$', views.IndexView.as_view(), name='index'), url(r'^specifics/(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'), url(r'^(?P<pk>[0-9]+)/results/$', views.ResultsView.as_view(), name='results'), url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'), ] And finally we have the tests.py part: ### SELENIUM ### class VoteTest(StaticLiveServerTestCase): @classmethod def setUpClass(cls): super(VoteTest, cls).setUpClass() cls.selenium = webdriver.Firefox() cls.selenium.implicitly_wait(10) Question.objects.create(question_text="Sample_question", days=1) Choice.objects.create(choice_text="Sample_choice", question=q, votes=1) def test_vote(self): self.selenium.get('%s%s' % (self.live_server_url, '/polls/')) self.selenium.find_element_by_xpath('//a[@id="1"]').click() # Here I get the "URL not found error", the URL is '.../polls/specifics/1/ As I said the URL is reachable from the webserver. I also print the values of the test DB during the tests and everything seems fine with IDs. … -

How to make login and signup in one url
Im new in Django. Got a problem. I have my urls.py: path('login/', auth_views.login, name='login'), path('reset/', auth_views.password_reset, name='reset'), path('logout/', auth_views.logout_then_login, name='logout'), path('signup/', views.signup, name='signup'), path('activate/<slug:uidb64>/<slug:token>/', views.activate, name='activate'), So i can login using one HTML file and signup using other. But i have a HTML including and login and signup. The problem is that if i use /login/ url i can only log in and if i try the same forms to sign up - it does not work. The same with signup (only signup). How can i make both that functions work using one url and one HTML file. Thanks! Here is HTML: <body> <div class="login-page"> <div class="form"> <form class="register-form" method="POST"> {% csrf_token %} <input type="text" name="username" placeholder="имя пользователя" required autofocus id="id_username" maxlength="150"/> <input type="text" name="email" placeholder="email" required id="id_email" maxlength="200" /> <input type="password" name="password1" placeholder="пароль" required id="id_password1"/> <input type="password" name="password2" placeholder="повторите пароль" required id="id_password2"/> <button type="submit">создать</button> <p class="message">Уже зарегистрированны? <a href="#">Войти.</a></p> </form> <form class="login-form" method="POST" action="{% url 'login' %}"> {% csrf_token %} <input type="text" name="username" placeholder="имя пользователя" for=<input type="text" name="username" maxlength="254" autofocus required id="id_username" /> <input type="password" name="password" placeholder="пароль" for=<input type="password" name="password" id="id_password" required /> <p style="color: red">{{ error }}</p> <button type="submit">войти</button> <p class="message">Не зарегистрированны? <a href="#">Создать аккаунт.</a></p> </form> </div> </div> … -
Django admin JavaScript on forms frontend
Is there a good/easy way of implementing the JavaScript from django.contrib.admin.static.js to your own forms on the frontend, like inlines.js, prepoplulate.js etc. so you can get the same behavior dealing with forms. Or is this even advisable. -
How do I negate/invert a django-filter (exclude *unless* filter is active)?
Given a filter set like this: class MyFilter(django_filters.rest_framework.FilterSet): include_unusual_entries = django_filters.BooleanFilter(method='noop') I would like the 'default' queryset to be MyModel.objects.exclude(unusual_state=True) and only if the include_unusual_entries filter is set, I would like it the queryset to be MyModel.objects.all() Am I missing an obvious way to solve this? I don't see a way to set invert=True on a filter, or a way to set always_filter so that I could put an if into the method. For now, I solved it by overriding the qs property on my filter set, but it feels pretty wrong: @property def qs(self): queryset = super(MyFilter, self).qs if 'include_unusual_entries' in self.data: # if inclusion is explcitly enabled return queryset else: # if inclusion is *not* explicitly enabled (the default) return queryset.exclude(unusual_state=True) -
How to put many fields of django-tables2 into one?
I have a django table declared as follow : class BookTable(tables.Table): user= tables.TemplateColumn("""{% include 'books/user.html' with user=record.created_by %}""") books= tables.TemplateColumn( """ {% if record.g_books.count %} <div class="panel-body"> {% include 'books/details/detail.html' with book=record %} </div> {% else %} No New Books {% endif %} <div> </div> """) actions = tables.TemplateColumn("""{% include 'books/action.html' with book=record %}""") I want to make changes on the order and some styles of fields and I want to render only one field that groups user, books and actions fields . Is that possible with django-tables2 or it's a bad way to do so ? New with django-tables2 , any advice is welcome Thanks. -

how do i use Django cluster or loading balance. Django +Nginx+uWSGI
i deployed the environment of Django +Nginx+uWSGI successfully. i wish i can run multi-django server with one nginx. the configuration below is nginx's conf: upstream django { server unix:///path/to/your/mysite/mysite.sock; # for a file socket #server 127.0.0.1:8001; # for a web port socket (we'll use this first) } does it work just use ip:port? e.g.: upstream django { #server unix:///path/to/your/mysite/mysite.sock; # for a file socket server 192.168.0.1:8001; # for a web port socket (we'll use this first) server 192.168.0.2:8002; server 192.168.0.1:8004; server 192.168.0.2:8004; } i want to use Unix sockets instead of ports. because the mysite.sock files maybe in many different remote hosts.how do i configure nginx's conf? thanks a lot and happy christmas! -
django-el(endless)-pagination not wokring with AJAX
I'm using django-el-pagination(Digg-style pagination) in my project, but the results don't appear to be using AJAX. I need to move the page without refreshing, but it seems that ajax is not working properly. view.py @page_template('dmmactress/actress_dev_page.html') def actress_dev(request, id, extra_context=None): instance = get_object_or_404(ActressInfo_two, pk=id) moviesinfo = ActressinfoMovielist_co.objects.filter(actressinfo_id=id).prefetch_related('movielist').order_by('movielist') context = { 'actresses': instance, 'moviesinfo':moviesinfo, } if extra_context is not None: context.update(extra_context) return render(request, 'dmmactress/actress_dev.html', context) actress_dev.html ........ <thead> </thead> <tbody id="entries" class="endless_page_template"> {% include page_template %} </tbody> ........ actress_dev_page.html {% load el_pagination_tags %} {% paginate moviesinfos %} {% for movieinfo in moviesinfo %} {{ movieinfo.movielist.movie_number|upper }} {% endfor %} {% get_pages %} {% if pages.paginated %} {{ pages }} {% endif %} The result is the same as the default paging without using ajax. Also, when I click the "page" link, I'm taken to "/? page = 2", which includes refreshing the entire page and is not what I want to do. And on the Chrome Console, no logs appear when the page reloads. (The js file has been successfully loaded.) What am I doing wrong? -
Restart server using any other key than Break
I am running a Django server in Windows on Google Compute Instance. I am connecting to it using Microsoft Remote Desktop app on macOS. The problem is whenever I want to quit the server I have to supply a Ctrl+Break command to the command prompt and my MacBook keyboard doesn't have a Break key. Even On-Screen keyboard doesn't have the Break Key. So instead of finding ways to find the break key, I want to find the ways to override the requirement of it. So my question is, is there any way I can change the shortcut for killing the server to ctrl+c or ctrl+z or any other available key instead of break in Django? -

Setting up two throttle rates in one view in django
I am using Django 1.11 and Python 2.7 and now tried to include throttling into my webservice. This seemed quite easy at the beginning as Django does all the work for you. But now I wanted to only throttle one of my views and differentiate between authenticated users and logged in users aswell as setting up a 'burst' rate (e.g. 5 requests per min) and a 'sustained' rate (e.g. 100 requests per day). Achieving this, I built 4 throttle-classes: class SustainedAnon(AnonRateThrottle): rate = '100/day' class BurstAnon(AnonRateThrottle): rate = '6/minute' class SustainedUser(UserRateThrottle): rate = '1000/day' class BurstUser(UserRateThrottle): rate = '20/min' I did not change the settings.py at all as it is not needed according to the docs (Django Throtte Docs). The only file I edited was my views.py in which I added this line to my Statistics class class Statistics(APIView): throttle_classes = (SustainedAnon, BurstAnon, SustainedUser, BurstUser) It almost does what it is supposed to do. It does only throttle the Statistics class and throttles logged in and anonymous users seperately, but it does not throttle the rates correctly. When not logged in, the App starts throttling after 3 requests instead of 6 and when logged in after 10 requests instead of … -

Notifications/Activity Stream using Multiple foreign Keys
I need to create a simple Notification app, that send messages to admin or users, depending on the action.
