Django-Tables2 LinkColumn and Column(linkify=True) returning famous Reverse error
I have been stuck on a problem that I had address previously (link goes to wrong item) but fixed it with some assistance by a helpful mechanical turk. Then I changed the model such that one of the fields went from ForiegnKey to ManyToMany, and broke something in the process. I am using django 2.1, python 3.6, and the latest django-tables2 version. Here is a bit of code. models.py class PI(models.Model): l_name = models.CharField('Last', blank=False, max_length=100, default='') f_name = models.CharField('First', blank=False, max_length=100, default='') ... def get_absolute_url(self): return reverse('pi-detail', args=[str(self.id)]) class Sample(models.Model): sample_name = models.CharField('Sample', max_length=16) pi = models.ForeignKey(PI, verbose_name='PI', on_delete=models.SET_NULL, null=True) ... def get_absolute_url(self): return reverse('sample-detail', args=[str(self.id)]) class Publication(models.Model): titlep = models.CharField('Title', max_length=200, blank=False, default='') sample = models.ForeignKey(Sample, on_delete=models.SET_NULL, null=True, blank=True, default='') pi = models.ManyToManyField(PI, verbose_name='PI') pdf = models.CharField('PDF', default='', max_length=500, blank=True) def get_absolute_url(self): return reverse('publication-detail', args=[str(self.id)]) def filename(self): return self.pdf def __str__(self): return '%s, (%s)' % (self.titlep, ' '.join(p.l_name for p in self.pi.all())) tables.py class PublicationTable(tables.Table): titlep = tables.LinkColumn('publication-detail', args=[A('pk')]) pi = tables.TemplateColumn(empty_values=(), orderable=False, template_code='''{% for pi in record.pi.all %} <a href="{% url "pi-detail" pi.pk %}">{{pi}}</a>, {%endfor%} ''') sample = tables.LinkColumn('sample-detail', args=[A('sample_id')]) pdf = tables.TemplateColumn(template_code='''{% load static %}<a href="{% static 'pdf/'|add:value %}" target="_blank">{{record.pdf}}</a>''') When I look at the rendered … -
Why this 2 form dosn't work with ajax in Django?
I am developing an application on django, and faced with strange problems with Ajax. On my website 4 forms should be processed using Ajax. And two of them work great. But 2 others not heard about Ajax at all. Consider working and non-working forms. views.py view working form def login_user(request): form = LoginForm(request.POST) context = { 'form': form, } if request.method == 'POST' and form.is_valid(): username = form.cleaned_data['user_login'] password = form.cleaned_data['user_password'] user = authenticate(username=username, password=password) response_data = {} if user and user.is_active: login(request, user) response_data['result'] = 'Ok' else: response_data['result'] = 'Bad' return HttpResponse(json.dumps(response_data)) else: return redirect('index') view non-working form def add_new_station(request, add_station_slug): form = AddStationForm(request.POST) myuser = get_object_or_404(User, id=request.user.id) print(request.user) if request.method == 'POST' and form.is_valid(): response_data = {} UserStation.objects.create( station=Station.objects.get(slug=add_station_slug), impressions=form.cleaned_data['impressions'], list=UserStationsList.objects.get(user=myuser) response_data['result'] = 'Ok' ) return HttpResponse(json.dumps(response_data)) else: return redirect('index') urls.py urlpatterns = [ path('', index, name='index'), path("add-in-list/<str:add_station_slug>/", add_new_station, name='new_station'), path('login/', login_user, name='login_action'), ... ] html html working form <form id="login_form" action="{% url 'login_action' %}" method="post"> {% csrf_token %} {{ formlogin }} <div class="text-center"> <button type="submit" class="btn btn-dark mt-2">Entry</button> </div> </form> html non-working form <form id="add_station_form" action="{% url 'new_station' choice_station.slug %}" method="post"> {% csrf_token %} {{ formaddstaion }} <div class="text-center"> <button type="submit" class="btn btn-outline-success mt-2">I visited this station</button> … -

Django dropdown [onChange] box with selected values but can't get the selected value
I have a dropdown selection of titles that upon selection of specific title, an action (should) run. What I have: form.py class CronForm(forms.Form): title = forms.ModelChoiceField(queryset=GlobalFID.objects.all().order_by('-title_date'), widget=forms.Select(attrs={"onChange":'change_title()'})) view.py [title_change_view ] my_form = CronForm() #initial=data return render(request, 'research/title_result.html',{"my_form":my_form}) html <form method="post" > {% csrf_token %} {{ my_form }} </form> and on the js side: function change_title() { var murl= "{% url 'title_change_view' %}"; window.location = murl; } my goal is to have the SELECTED title from {{my_form}} in the view title_change_view. While the redirection works, I can't get the selected value. Strategies I considered/tried: In the title_change_view I added if request.method == 'POST': but it's not a post (so it overlook it) so I can't read the form. var murl= "{% url 'title_change_view' %}"; to add additional parameter ?title=[SELCTED_VALUE] but couldn't figure out how to add the SELECTED title into murl or into the change_title() fuction. any idea? -

TypeError: Object of type date is not JSON serializable
I am trying to query database on the basis of multiple parameters, basically I fetch all the records from a table and then filter them out according to the parameters passed. Although the search portion works fine but when the resultant query set is returned, I get the following error: TypeError: Object of type date is not JSON serializable I am not sure why that happens since I'm not trying to serialize anything.

How to deal with time zone changes in Django?
I have a Django app with PostgreSQL as database that logs actions of users from different regions. Recently, one of the regions (Volgograd, Russia) had its timezone permanently changed from UTC+3h to UTC+4h on October 28, 2018. In January 2019, pytz had updated in pypi, and I updated pytz dependency so the region received correct time zone setting. The problem is events that happened before the October 28, 2018 are kind of "not synchronised" with the current time zone now. If I understand it correctly, after pytz update Django now believes that the time zone is and always was UTC+4h, so events before the October 28, 2018 are shifted one hour forward. For example, it shows 2pm local time instead of 1pm. The main requirement is users should be able to see correct time in their local timezone. For example, if the user performed the action at 1pm every day before and after October 28, 2018, she should see 1pm for all events. Even though events that happened before October 28 now have different UTC time than events that happened after that date. Currently events datetimes are displayed using model method: class Event(models.Model): date_created = models.DateTimeField(auto_now_add=True, blank=False, null=False) organization = … -

why is the prompt of my virtual environment different from its name?
I'm building a Django Project, and I first created a virtual environment. Before I work on it, I go to the /bin/ of my virtualenv, then I go source activate Usually, it then says: (myVirtualEnv) because that's how I named it. And I can do Python manage.py runserver, and all these sort of things. But since yesterday, after mysource activate, it says : (base) ... and the other doesn't work ! I don't understand what happened. Any help ? -
Filter by intermediary model field in Many-to-Many relationship
I want to create a friendship relationship between organisations. I added a connected_organisations field in my Organisation model: class Organisation(models.Model): ... connected_organisations = models.ManyToManyField('self', related_name='organisations_connected', through='Connection', through_fields=('requester', 'requestee'), symmetrical=False, blank=True) Then I created Connection as the intermediary model: class Connection(models.Model): requester = models.ForeignKey(Organisation, related_name='requester', null=True, on_delete=models.CASCADE) requestee = models.ForeignKey(Organisation, related_name='requestee', null=True, on_delete=models.CASCADE) is_connected = models.BooleanField(default=False) The is_connected field indicates whether the friendship request is approved by the requestee or if the request is still pending. I create a connection between org1 and org2 with: Connection.objects.create(requester=org1, requestee=org2) I know I can do: org1.connected_organisations.all() and this will return org2, but I cannot find how I can filter them by the is_connected field. I tried something like: Organisation.objects.filter(connected_organisations__requestee=org0, connected_organisations__is_connected=True) but I am getting: django.core.exceptions.FieldError: Related Field got invalid lookup: is_connected -

Wagtail single-page site
I made a single-page site in static HTML with shiny screen-height divs, and a smooth scrolling function from a navbar. The website is expected to have a mixture of simple body text, a few images, and a card-deck. It all worked nicely and I was happy. While I have used wagtail for very simple websites in the past, I cannot work out a way of making a single page site where the home page goes at the top followed by all the child pages in order. Is this possible with Wagtail's page models? -

Fetching all objects hierarchically nested by ForeignKey in one query
I'm modeling a folders structure in my application. Every element (folder or file) has its own id and id of its parent: class Folder(TimeStampedModel): id = models.UUIDField(primary_key=True, default=uuid.uuid4) parent_folder = models.ForeignKey( 'folders.Folder', on_delete=models.CASCADE, null=True, ) I want to fetch all nested children of a folder. Obviously it can be done by recursively querying "find all objects with this parent_id", calling this recursively on all the found objects. But I'm wondering if there is a possibility in Django to do this in one query, so that I don't have to connect to the database X times but only once. What is the best approach here? -

Django Inlineformset Factory validation is not working
I have two forms one is supplier detail and one is contact for suppliers so I am using inlineformset_factory to combine both form and able to add contacts when I add supplier and that function is working good. The only problem is it show form validation error for the supplier form but not for the contacts (inlineformset). Forms.py class SupplierForm(forms.ModelForm): class Meta: model = Supplier fields = ('category','name','alternate_name','logo','address1','address2','city','zip','region','region_code','country','country_code','detail') class ContactForm(forms.ModelForm): class Meta: model = Contact fields = ('contact_type','job_title','first_name','last_name','phone','email','skype','wechat') def clean(self): if any(self.errors): return ContactFormSet = forms.inlineformset_factory(Supplier, Contact, form=ContactForm, extra=1) Views.py class CreateSupplierView(LoginRequiredMixin,CreateView): form_class = SupplierForm model = Supplier def form_valid(self, form): context = self.get_context_data() contacts = context['contacts'] with transaction.atomic(): self.object = form.save() if contacts.is_valid(): contacts.instance = self.object contacts.save() return super(CreateSupplierView, self).form_valid(form) def get_context_data(self, **kwargs): context = super(CreateSupplierView, self).get_context_data(**kwargs) if self.request.POST: context['contacts'] = ContactFormSet(self.request.POST) else: context['contacts'] = ContactFormSet() return context If supplier form is not valid it forwards it to add/edit form and show error but if supplier form is good the only contact has an error then it forwards that to supplier list and doesn't show any error. how can I show the same edit/add form with the error if contacts form is not valid?
