NoReverseMatch - not a registered namespace
Hello, I am new to Django and I was working at my first project, but I got NoReverseMatch with Exception Value: 'hiring_log_app' is not a registered namespace in base.htlm which follows: href="{% url 'hiring_log_app:index' %}" >Hiring Log href="{% url 'hiring_log_app:topics' %}" >Topics I made sure my namespace was correct and I looked at the other topics already opened without figuring out how to solve the issue. I paste urls.py: from django.contrib import admin from django.conf.urls import include, url urlpatterns = [ url(r'^admin/', include(admin.site.urls)), url(r'', include ('hiring_log_app.urls', namespace='hiring_log_app')), ------ hiring_log_app/urls.py: """Define URL patterns for hiring_log_app""" from django.conf.urls import url from . import views urlpatterns = [ url(r'^$', views.index, name='index'), url(r'^topics/$', views.topics, name='topics'), ] ----- views.py: from django.shortcuts import render from .models import Topic def index(request): """The home page for hiring_log_app""" return render(request, 'hiring_log_app/index.htlm') def topics(request): """ list of topics""" topics = Topic.objects.raw( "SELECT text FROM HIRING_LOG_APP_TOPIC;") context = {'topics' : topics} return render(request, 'hiring_log_app/topics.htlm', context) ------- Does anyone know where I am making a mistake? Thnaks a lot in advance, any help would be precious. Thanks again. -
Related resources on a nested URL in Django Rest Framework
I have two models, Foo and Bar. Bar has a foreign key to Foo. I have a ModelViewSet for Foo and I want the route /api/foos/<pk>/bars/ to return all the bars related to the given foo. I know this can be done using actions. For example class FooViewSet(viewsets.ModelViewSet): serializer_class = FooSerializer queryset = Foo.objects.all() @action(detail=True, methods=['GET']) def bars(self, request, pk): queryset = Bar.objects.filter(foo=pk) serializer = BarSerializer(queryset, many=True) return Response(serializer.data) @bars.mapping.post def create_bar(self, request, pk): request.data['foo'] = pk serializer = BarSerializer(request.data) serializer.is_valid(raise_exception=True) serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) However, this feels like a lot of unnecessary boilerplate code. Is this possible to do in viewsets in a more convenient way? If not, what is the normal DRF way of doing it? A solution with a different URL is also acceptable for me as long as it minimizes boilerplate code. -
Django - how to add prefix to Mixin attributes (possible?)
There is too much relations and chains of actions in my project so I decided to eliminate some relations and use Mixins instead to keep things DRY. For example: class AddressMixin(BaseModel): address_zip = models.CharField(max_length=6, null=True, blank=True, verbose_name='PSČ') address_lat = models.DecimalField(max_digits=24, decimal_places=20, null=True, blank=True) address_lng = models.DecimalField(max_digits=24, decimal_places=20, null=True, blank=True) ... class Meta: abstract = True def some_method... There are many models using Address where I use this as a Mixin but sometimes, I need two or three types of addresses in one model. class Client(..): home_address = OneToOneField('addresses.OldAddressModel',...) work_address = OneToOneField('addresses.OldAddressModel',...) Here I can't just use AddressMixin like Client(AddressMixin,Model) since I need two different addresses. I would like to use AddressMixin two times with different prefixes, so in final model, there would be home_address_city and work_address_city. Is it possible to do that? I was thinking about some MixinFactory which takes Mixin and prefix and then it prefix all attributes (and maybe methods too but I can live without prefixed methods...). -
Django static files not loading with no error signs
When I run django server and try to load html files, it's not loading css files. I don't see any errors on terminal or the website itself - just loading animation in the background.

Django inlinefomrset delete
Here is a mystery. I cannot get the inlineformset deletion to work property. I have followed the docs to delete forms in my formset processing: # In my forms.py: def clean(self, *args, **kwargs): ''' Custom clean method to handle deletion ''' super(BaseDevelopmentTypeInlineFormSet, self).clean(*args, **kwargs) if any(self.errors): return # Everything beyond this point is clean cd = self.cleaned_data for form in self.forms: the_can_delete = self.can_delete # can_delete returns True the_should_delete = self._should_delete_form(form) # _should_delete returns False! form_fields = [ field for field in form.fields ] if self.can_delete and self._should_delete_form(form): continue form_cd = form.cleaned_data And, here are the relevant sections of the views.py: if development_type_formset.is_valid(): development_types_cd = development_type_formset.cleaned_data forms_marked_for_deletion = development_type_formset.deleted_forms assert False # forms_marked_for_deletion correctly returns the forms that have been marked for deletion the_kwargs = {'development_project': active_development_project } development_type_formset.save(**the_kwargs) assert False # the_development_types = [] is returned return HttpResponseRedirect(reverse('development:add_details', args = (the_id,))) After submitting, the redirection to another url happens successfully. But, when I go back, I still see the forms that should have been deleted. Originally, I thought the problem is with _should_delete, so I commented the part of the code calling _should_delete out. This made no difference. The redirection happened successfully, but deletion failed again. I have searched … -
How to iterate across HTML elements a specific number of times?
I'm having trouble coming up with working logic for the use case of repeating a set of HTML elements across columns. Simplified HTML as an example: {% for day in days %} <div class="container"> <div class="row"> {%for room in day.rooms%} <div class="col-sm-3"> <section class="box"> <h4>{{room.name}}</h4> {%for session in day.sessions%} {%if session.leftpos == room.leftpos %} {%if session.id%} <a href="session/{{session.id}}-{{session.title|slugify}}/">{{session.timeslot}}<br/><b>{{session.title}}</b><br/></a> {%else%} {{session.timeslot}} - <b>{{session.title}}</b> {%endif%} {%for speaker in session.speakers %}{%if loop.first%}{%else%}, {%endif%}<i><a href="speaker/{{speaker.id}}-{{speaker.name|slugify}}/">{{speaker.name}}</a></i>{%endfor%} {%endif%} {%endfor%} </section> </div> {%endfor%} </div> </div> {%endfor%} As this currently works, it looks for rooms depending on the sortkey, and lines up the talks corresponding with what rooms by going off that sortkey (if session.leftpos == room.leftpos). I have another variable (session.cross_schedule) which applies to talks which span across all 3 rooms, meaning that's the featured session. What I need to determine is how best to repeat the session information (everything within for session in day.sessions) across for room in day.rooms, but only if it's session.cross_schedule. Ideally, these cross-scheduled talks would appear at the proper time in the schedule rather than being separated from the rest. Any ideas or guidance would be much appreciated! -
Implement google autocomplete for address fields whilst using django models for forms
I have used django models to create the forms then loaded in the fields using crispy forms. The current implementation uses a standard text field to take in the address straight from the models. I would like to add the auto complete feature so that no incorrect addresses are entered in. I am unable to access the raw code as crispy forms loads everything in straight from the models so I cannot attach the code required for the autocomplete feature. I have tried to add a block in to manually add in the address however, this can only be added at the top or the bottom of the form. This is a problem as I need to add the address after the user entering the title of the listing. forms.py class ListingDevelopmentForm(forms.Form): title = forms.CharField() slug = forms.SlugField() description = forms.CharField(widget=forms.Textarea) first_line_address = forms.CharField() second_line_address = forms.CharField() postcode = forms.CharField() number_of_properties= forms.IntegerField() site_plan = forms.IntegerField() price = forms.DecimalField() rent = forms.DecimalField() ownership = forms.CharField() tenure = forms.CharField() from.html <form method="post" action='.' enctype='multipart/form-data'> {% csrf_token %} {{ form|crispy }} {% block main1 %} <!-- this is where I have added the block which allows me to manually add in the code … -
Is there a better way to display additional information from the Django model in the Django admin
Is there a better way to make the code less repetitive by moving the "CONN" to where is can still be used but where it only need to be written once.

How to configure vue for correct integration with django
I would like to write an application using django for Web-API and vue.js for frontend. I find many tutorials how to do it and decided to follow this one https://medium.com/@rodrigosmaniotto/integrating-django-and-vuejs-with-vue-cli-3-and-webpack-loader-145c3b98501a Unfortunately I have a problem whith configuration of WebPack. It is written that I have to change my URL to http://0.0.0.0:8080. But when I did it, my application's page become blank. Expected result: I see Vue.js start page when running django server. How can I fix it? -
serializing nested model objects in django
say i have some models in one of my apps in the django project as follows: class BaseModel(Model): # some fields... class FirstNestedLevel(Model): parent_id = ForeignKey(BaseModel) # other fields class SecondNestedLevel(Model): parent_id = ManyToManyField(FirstNestedLevel) # other fields class ThirdNestedLevel(Model): parent_id = ForeignKey(SecondNestedLevel) # other fields It looks fine when there is only 2 level of nested objects to override the create and update methods on each serializer to make them work, but what if we have more levels of nested objects? I usually do this by implementing create and update methods to handle one level down and pass downer objects to their own serializer to do the rest. Is there a better way to implement serializer classes? -

Select2 in Bootstrap with Dependent/Chained autocomplete List. Did not work
I'm trying to create Dependent/Chained Dropdown List (with auto-complete) with Bootstrap4 and Django. I'm trying to use this solution.

Is it possible to add some simple javascript code in template that will run it again so that the second drop down field react properly again. Any help will be appreciated. -
