Django allauth: empty 'signup_url, login_url and logout_url'
Using django 1.11.4 and package django-allauth==0.33.0 Login works fine The default login template 'login.html' contains a link to a signup page: <p>{% blocktrans %}If you have not created an account yet, then please <a href="{{ signup_url }}">sign up</a> first.{% endblocktrans %}</p> and that works fine but any other page then /account/* its just empty base.html: <div class="nav-wrapper"> <a href="/" class="brand-logo">Logo</a> <ul id="nav-mobile" class="right hide-on-med-and-down"> {% if user.is_authenticated %} <li> Welcome: {% user_display user %}</li> <li><a href="{{ logout_url }}">logout</a></li> {% else %} <li><a href="{{ login_url }}">sign in</a></li> <li><a href="{{ signup_url }}">sign up</a></li> {% endif %} <li></li> </ul> </div> I use the base.html on /accounts/* as well as on the index. on /accounts/* its works fine but on the index the {{ logout_url }} etc are empty.

In Django, getting next/previous object by date when some share the same date
In Django I have a Letter model: class Letter(models.Model): letter_date = models.DateField(blank=False, null=False) When viewing an individual letter, using a DateDetailView(), I want to show "next" and "previous" links. To get the next/previous Letter I can do this in one of the view's methods (and similar to get next_letter: try: previous_letter = self.model.objects.filter( letter_date__lt=date).order_by('-letter_date')[:1].get() except self.model.DoesNotExist: previous_letter = None That works fine if there's only one Letter per day, but some days have multiple letters, and this code will skip subsequent letters on the same day. How can I ensure next/previous doesn't skip letters? This doesn't sound hard, but my brain is struggling... -

IE11 strips url parameters?
In our Django project, we have 4 hrefs. Each href goes to the same url but has different URL parameters. To differ between them, we need to specify parameter. Unfortunately, IE11 strips these parameters. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>****.com</title> <link ....> <script src="https://code.jquery.com/jquery-3.2.1.min.js" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4=" crossorigin="anonymous"></script> <script src="/static/js/jquery.formset.js"></script> <script src="/static/Flat-UI/dist/js/flat-ui.js"></script> <script> $(document).ready(function () { $('.alert').delay(4000).fadeOut('slow'); }); </script> </head> .... lot of code ... <div class="container"> <div class="col-md-6 top-margin-half"> <a class="btn btn-primary pull-right" style="width: 50%;" href="/dashboard/doklady/vytvorit/?typ=faktura">FA</a> </div> <div class="col-md-6 top-margin-half"> <a class="btn btn-primary col-md-6" style="width: 50%;" href="/dashboard/doklady/vytvorit/?typ=zalohova_faktura">ZALFA</a> </div> ....

Django NotImplementedError: annotate() + distinct(fields) is not implemented
I want to count the total number of specific values in the structure field. Fund.objects.all().exclude(structure__isnull=True).extra(select={'Structure': 'structure'}).values('Structure').annotate(total=Count('structure')).order_by('-total') But before I do, I want to apply distinct() function so that only the objects with distinct id will be used for the query.

django - form submits information but does not save to database
I've been stuck on this problem for a good bit -- the form is able to submit but will not save to the database. I've even sent an email through the one form, but it won't save. I'm making a CRM and have a contact, communication, and email app. This view has three forms so far, one for each model. The contact form is able to save to the DB. The other two are able to submit but will not save. The two forms not saving can both be redirected back to the refreshed contact detail with their instance and data still available on the form. So it must be storing properly, just not saving. I'm not sure what I'm missing. Let me know if you need me to add other files. views.py---------- def contact_detail(request, contact_id): contact = get_object_or_404(Contact, pk=contact_id) if request.method == 'POST' and 'contact' in request.POST: contactForm = ContactForm(request.POST, prefix='contact', instance=contact) if contactForm.is_valid(): contactForm.save() else: contactForm = ContactForm(prefix='contact', instance=contact) if request.method == 'POST' and 'email' in request.POST: contactForm = ContactForm(prefix='contact', instance=contact) messageForm = MessageForm(request.POST, prefix='email', instance=contact) if messageForm.is_valid(): messageForm.save() form_email = contact.contact_email form_message = messageForm.cleaned_data.get("message") subject = messageForm.cleaned_data.get("subject") from_email = settings.EMAIL_HOST_USER to_email = [from_email] contact_message = "%s" % … -

Django: User Reporting System
I wants to create a way in which user can report something to the site admin. Is it a good way to store the url of the page that they are on so that when they click report button from specific page specific url is sent to us?

Also, please suggest me if there's a better way for doing this? Thanks in advance! -

filter query results without launching a new sql query
With this code I expected that an sql query would run only on 'all_user_videos' and that the subsequent filter would use the results stored in 'all_user_videos' to do the filter. # Get all user videos all_user_videos = Video.objects.filter( author = user ) # User pending videos pending_videos = all_user_videos.filter( status = 'pending_review' ) # Get user Video that need information info_required_videos = all_user_videos.filter( status = 'info_required' ) # Get user video on sale on_sale_videos = all_user_videos.filter( status = 'on_sale' ) context = { "user_member_profile": instance, 'pending_videos' : pending_videos, 'info_required' : info_required_videos, 'on_sale' : on_sale_videos } It seems not to be the case, and that each filter runs a query.

Tables not showing up and migrations not visible after `python manage.py migrate`
I'm following the official tutorial on Django and have run python manage.py migrate in https://docs.djangoproject.com/en/1.11/intro/tutorial02/ . After this, I'd expect some files to show up in polls/migrations, but there is just an empty __init__.py there, and when I run sqlite3 and type .tables or .schema, nothing is output. Still, the python manage.py migrate command seems successful: $ python manage.py migrate Operations to perform: Apply all migrations: admin, auth, contenttypes, sessions Running migrations: Applying contenttypes.0001_initial... OK Applying auth.0001_initial... OK Applying admin.0001_initial... OK Applying admin.0002_logentry_remove_auto_add... OK Applying contenttypes.0002_remove_content_type_name...
