Advanced Search in Django with Multiple Fields and Keeping Filters in Pagination
I have this piece of code that is working already. It enables you to have a search form, to search in a specific table with multiple filters. The results are paginated, and this form allows you to keep these filters when you browse multiple pages. The problem I'm having now is that I am reusing this piece of code in another scenario, and it involved checking one filter in multiple fields in the database table. Example of a standard scenario: First Name Last Name City In this case, the view will be as such: def clean_filters(filters): filters = {k: v for k, v in filters.items() if v} return filters def search(request): filters = { "user__first_name__icontains": request.GET.get("fname_kw"), "user__last_name__icontains": request.GET.get("lname_kw"), "city__name__icontains": request.GET.get("city_kw"), } html_queries = { "fname_kw": request.GET.get("fname_kw"), "lname_kw": request.GET.get("lname_kw"), "city_kw": request.GET.get("city_kw"), } filters = clean_filters(filters) html_queries = clean_filters(html_queries) people = Person.objects.filter(**filters) page_num = request.GET.get("page", 1) p = Paginator(people.order_by("-pk"), 12) people = p.get_page(page_num) context = { "people": people, "cities": City.objects.all(), "filters": html_queries, } return render(request, "pages/index.html", context) And the HTML will be as such: <form method="GET" action="{% url 'search' %}"> <div class="row"> <div class="col-xl-3 col-lg-3 col-md-3 col-sm-12 col-xs-12"> <div class="row"> <div class="col-6"> <input class="form-control" name="fname_kw" id="search_fname" placeholder="First Name" /> </div> <div class="col-6"> … -

Can multiple values be assigned to one variable without brackets "[]" or parentheses "()" (Python)
From this django answer in SO, I found 3 variables "JAN", "FEB" and "MAR" in the class "Month" extending "models.TextChoices" as shown below: # "models.py" from django.db import models class MyModel(models.Model): class Month(models.TextChoices): JAN = "1", "JANUARY" # Here FEB = "2", "FEBRUARY" # Here MAR = "3", "MAR" # Here # (...) month = models.CharField( max_length=2, choices=Month.choices, default=Month.JAN ) And multiple values are assigned to each variable without brackets "[]" which creates Array or parentheses "()" which creates Tuple as shown below: JAN = "1", "JANUARY" FEB = "2", "FEBRUARY" MAR = "3", "MAR" Now, can multiple values be assigned to one variable without brackets "[]" or parentheses "()"? -

Django-tables2 exporting badly

Extend User model in Django with jwt authorization
I am trying to extend User model in Django. I already have authorization using jwt Token and I am currently trying to add another field to User model, such as phone number and address. My views.py looks like this: class MyObtainTokenPairView(TokenObtainPairView): permission_classes = (AllowAny,) serializer_class = MyTokenObtainPairSerializer class RegisterView(generics.CreateAPIView): queryset = User.objects.all() permission_classes = (AllowAny,) serializer_class = RegisterSerializer models.py like this: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) phone_number = models.IntegerField(blank=False) address = models.CharField(max_length=500, blank=True) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: Profile.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_profile(sender, instance, **kwargs): instance.profile.save() In here I'm trying to create another class that will store phone number and address. How can I incorporate my Profile class into User so that it will create new user model and what is more use earlier implemented Token authorization. -
Multiple nested choices in Django models
Forgive me if I'm not describing this correctly - I'm still learning and I've hit a wall with a problem I'm working on. I want to create a way (in the Admin backend for now) for users to show the books they like by fiction/non-fiction, age-range, genre(s) and sub-genre(s). So, a user who liked gothic horror books could select fiction>adult>horror>gothic. Or, a user who likes literally all YA books could select fiction>Young Adult and their selection would cascade down to every genre and sub-genre. I think the Choices field option and the MultiSelectField functionality might be a start, but there doesn't seem to be a way to add 'layers' to the choices beyond the categories below, and it seems like an inelegant solution when there could be hundreds of choices. I also don't know how it could be presented in the Admin - ideally with checkboxes that can 'open up' to show the sub-categories beneath them. GENRE_CHOICES = ( ('Fiction', ( ('FCH', 'Childrens'), ('FMG', 'Middle Grade'), ('FYA', 'Young Adult'), ('FAD', 'Adult'), )), ('Non-Fiction', ( ('NCH', 'Childrens'), ('FMG', 'Middle Grade'), ('FYA', 'Young Adult'), ('FAD', 'Adult'), )), ) genres = MultiSelectField(max_length = 100, choices=GENRE_CHOICES, null=True) I don't even know the name of … -

How do you pass options to Django-flatpickr date picker?
Im trying to implement a datetime picker on a Django app but im having some trouble working out how to pass options to the picker using the django-flatpickr package -->docs here: django-flatpickr. The docs really just get you started but don't go into any detail on how to apply some options and filter provided by the flatpickr.js package. I have successfully implemented the basics with the form fields and passing it to and from the the template which all works fine. However im having difficulty passing options i.e a start date, end date, allowed dates, making sure dates can't be selected I the past etc So the backend: forms.py class DatePickerForm(forms.Form): id = forms.CharField(widget=forms.HiddenInput) date_from = forms.DateTimeField(widget=DateTimePickerInput()) date_to = forms.DateTimeField(widget=DateTimePickerInput()) amount = forms.TypedChoiceField(choices=PRODUCT_QUANTITY_CHOICES, coerce=int) views.py def check_availability(request): #Get date time vals from client, pass to check_availabilty to query db if request.method == 'POST': form = DatePickerForm(request.POST) if form.is_valid(): cd = form.cleaned_data availability = check_availability(cd['id'], cd['date_from'], cd['date_to'], cd['amount']) else: print('Not bloody valid') return HttpResponse(f'Availabilty = {availability}') ClientSide: mytemplate.html <form action="{% url 'check_availability' %}" method="post"> {{ date_form.media }} {{ date_form.as_p }} <input type="hidden" name="id" value="{{ rental.id }}"> {% csrf_token %} <br> <button type="submit" value="Check Dates">Check Availability</button> </form> So what im really looking … -

Django + Django Rest Framework: get correct related objects on intermediate model
I have an intermediate model with the following fields: class UserSkill(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) skill = models.ForeignKey(Skill, on_delete=models.CASCADE, related_name='user_skills') disabled = models.BooleanField(default=False) As you can see, it has two foreign keys, one to the auth user and one to another table called skill. I am trying to get all Skills assigned to an specific user, so I do the following get_queryset in my ViewSet: class AssignedSkillViewSet(viewsets.ModelViewSet): queryset = Skill.objects.all() serializer_class = AssignedSkillSerializer permission_classes = [permissions.IsAuthenticated] def get_queryset(self): user = self.request.user return Skill.objects.filter(user_skills__user=user, user_skills_user__disabled=False)) Now, I also need to include the intermediate model information in the API, which I can access trough users_skills related name in DRF's Serializer, as follows: class AssignedSkillSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Skill fields = [ 'id', 'url', 'title', 'description', 'user_skills', ] But when I try to get that information it returns ALL user_skills related to the assigned skill, no matter if they are assigned to other users. I need the related model information only for that user and that skill. For Example: If I have a skill named Math, and a user named Maria related_skills = Skill.objects.filter(user_skills__user=user, user_skills_user__disabled=False)).user_skills.all() The above code will return: [ <UserSkill: Math+Jenniffer>, <UserSkill: Math+Gabriel>, <UserSkill: Math+John>, <UserSkill: Math+Maria>, ] I only … -

Retrieving a pre-specified range of objects in django
I am creating a blog application, and I want to create a function that gives me access to a specific object(blog in this case) and render it on the view. I also want help with creating another function that will create access to a range of blog posts, say 0-3. Here is my index.html <div class="row g-5"> {% for post in posts %} <div class="post-entry-1 col-lg-4 box mx-1"> <a href="single-post.html"><img src="{{post.image.url}}" class="post_img"></a> <div> <div class="post-meta"><span class="date">Culture</span> <span class="mx-1">&bullet;</span> <span>{{post.created_at}}</span></div> <h2><a href="">{{post.title}}</a></h2> </div> <p class="mb-4 d-block">{{post.body|truncatewords:75}}</p> <div class="d-flex align-items-center author"> <div class="photo"><img src="{% static 'assets/img/person-1.jpg' %}" alt="" class="img-fluid"></div> <div class="name"> <h3 class="m-0 p-0">OlePundit</h3> </div> </div> </div> {% endfor %} It could also be a for or a while loop. I don't know how to edit the for loop on the index.html in order to access a specified range My view def index(request): posts = Post.objects.all() return render(request, 'index.html', {'posts':posts}) -
Manually caching a view in Django
I'm using Django 4.0 and I have some few pages that takes a bit to load since they have to load lots of stuff from the database. These pages are static, they never change, and I don't want the users to wait, so I want to cache them as soon as the server goes up. Unfortunately I'm not finding a way to do so (I tried the @cache_page decorator, but it only caches the page after the first visit). How could I accomplish this? Thank you. -
