Paginating AJAX results on a Django Template
I have a basic Django template that displays the objects in the database and I have used Django's pagination and it works just fine. However, I have a sort functionality on the template that is tied with an AJAX function that updates the template based on the choice picked. The results get displayed just fine, but I would like to paginate this new updated data but I've had no luck so far. Here is my code: The views.py def open_challenges(request): the_tags = ChallengeTag.objects.all()[:10] the_audiences=ChallengeAudience.objects.all()[:10] url_parameter = request.GET.get("q") if url_parameter: challenges = Challenges.objects.all().filter(Q(status='Open') & Q(offered_by__icontains=url_parameter)).order_by('id') else: challenges = Challenges.objects.all().filter(status='Open').order_by('date_posted') paginator = Paginator(challenges, 2) try: page = int(request.GET.get('page', '1')) except: page = 1 try: posts = paginator.page(page) except(EmptyPage, InvalidPage): posts = paginator.page(paginator.num_pages) if request.is_ajax(): html = render_to_string( template_name = "mainapp/open-challenges-partial.html", context={"challenges":posts} ) data_dict = {"html_from_view":html} return JsonResponse(data=data_dict) context = { 'challenges':posts, 'the_tags':the_tags, 'the_audiences':the_audiences } return render(request, 'mainapp/open-challenges.html', context) The open-challenges-partial.html <div class="row" id="replaceable-content"> {% for challenge in challenges.object_list %} <p>{{challenge.title}}</p> <p>{{challenge.challenge_summary}}</p> {% endfor %} </div> ..... <nav aria-label="Page navigation example"> <ul class="pagination circle-pagination justify-content-center"> {% if challenges.has_previous %} <li class="page-item"> <a class="page-link" tabindex="-1" href="?page={{challenges.previous_page_number}}"><i class="fas fa-angle-double-left"></i></a> </li> {% endif %} {% for pg in challenges.paginator.page_range %} {% if challenges.number == pg %} … -
how can I build a query where I can limit the access to lessonmodule based on the membership?
I am trying to limit the access based on URL , and database where the initial user could see all courses, and lessons which this means all syllabus, but however at the same time it contains a lesson module where not all users can have access to, and I want if the given user is free then and tries to access to a paid lesson module it will keep the object: None while if the user is paid will be able to access the content of that lesson module: example: /courses /javascript /javascript/intro /javascript/intro/hello_world # free ones /javascript/intro/if_else # paid accounts views class LessonDetailView(LoginRequiredMixin, View): def get(self, request, course_slug, lesson_slug, *args, **kwargs): lesson = get_object_or_404(Lesson.objects.select_related('course').prefetch_related('lessonmodule_set'), slug=lesson_slug, course__slug=course_slug) context = { 'object': lesson, 'previous_lesson': lesson.get_previous_by_created_at, 'next_lesson': lesson.get_next_by_created_at, } return render(request, "courses/lesson_detail.html", context) my old version view class LessonDetailView(LoginRequiredMixin, View): def get(self, request, course_slug, lesson_slug, *args, **kwargs): course = get_object_or_404(Course, slug=course_slug) lesson = get_object_or_404(Lesson.objects.select_related('course'), slug=lesson_slug, course__slug=course_slug) user_membership = get_object_or_404(UserMembership, user=request.user) user_membership_type = user_membership.membership.membership_type lesson_allowed_mem_types = lesson.allowed_memberships.all() context = { 'object': None } if lesson_allowed_mem_types.filter(membership_type=user_membership_type).exists(): context = { 'object': lesson, 'previous_lesson': lesson.get_previous_by_created_at, 'next_lesson': lesson.get_next_by_created_at, } return render(request, "courses/lesson_detail.html", context) template {% extends 'courses/base.html' %} {% block post_detail_link %} {% if object is not … -
Adding Data through For-Loop deletes old data
I have created a e-commerce project. I have 3 models. Item, CartItem, Placeorder(checkout). I am looping through user's cart which has multiple items so that I can get each item and make a placeorder instance. But the for loop works only for the first time and when I try to placeorder(checkout) again with multiple items, the old data(records) are deleted and replaced by new data in the for loop. I do not understand this behavior. I cannot get past this. Maybe I am making some silly mistake. models.py SUB_CATEGORY_CHOICES = ( ('Veg','Veg'), ('Non-Veg','Non-Veg'), ) QUANTITY_CHOICES = ( ('Half','Half'), ('Full','Full') ) class Item(models.Model): name =models.CharField(max_length=1000) description =models.CharField(max_length=2000) # snacks, maincourse, soups, rice, ice-cream category =models.CharField(max_length=1000) # veg, non-veg # sub_category =models.CharField(max_length=1000,blank=True,null=True) sub_category =models.CharField(choices=SUB_CATEGORY_CHOICES, max_length=1000) images1 =models.FileField(upload_to='food_image',blank=True,null=True) images2 =models.FileField(upload_to='food_image',blank=True,null=True) price =models.CharField(max_length=500) add_date =models.DateTimeField(default=timezone.now) # half, full quantity_size =models.CharField(choices=QUANTITY_CHOICES,max_length=1000, blank=True,null=True) avg_rating =models.FloatField(default='0',blank=True,null=True) def __str__(self): return '%s - %s - %s' % (self.id,self.name,self.price) class Meta: ordering = ['-add_date'] class CartItem(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) the_item = models.ForeignKey(Item, on_delete=models.CASCADE) quantity = models.IntegerField(default=1) price = models.IntegerField() def __str__(self): return '%s - %s' % (self.the_item.name, self.the_item.sub_category) class Placeorder(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) order_items = models.ForeignKey(CartItem, on_delete=models.CASCADE) item_quantity = models.IntegerField(default=1) first_name = models.CharField(max_length=200, null=True) last_name = models.CharField(max_length=200, null=True) … -

How to change a label of another page using hyperlink?
I am new to Django and I'd like to ask if it is possible to change a page's label using a hyperlink from another page. I want to pass a value, ex. '1' and use it as a label for another template. I am able to redirect from page to page using hyperlink but I have no idea how to pass some parameters to be used by another. The Hyperlink's purpose is to tell the other page that it is for a certain value. Here's the code of my hyperlink: //It is a hyperlink with image. <a class="btn bgImg" href="{% url 'trend_view'%}"></a> Here's the code in my view: def stage_trend_view(request, value): args={ val = value} template = loader.get_template("Hole_Analyzer/trend_per_stage.html") return HttpResponse(template.render(args, request)) And here's the template I want to use the value being passed: {% extends "base.html" %} {% load static %} {% block title %}Stages{% endblock %} {% block content-nav %} {% endblock content-nav %} {% block card_title %}Trend for Stage {{val}} {% endblock card_title %} {% block content-Card %} <div class="card-body"> <div class="row"> <p>This is Graphs and shits</p> </div> </div> {% endblock content-Card %} {% block scripts %} {% endblock scripts %} Here's the url.py: path(r'^trend/(?P<value>\d+)/$', stage_trend_view, name='trend_view') -

Working with Mapbox JS in a Django project
I am working with a MapBox JS map element in a Django project, and the intention is to use the returned map result to query an SQLite3 database.

If the latter, I would appreciate any advice/instruction on how to go about doing this. -

Django Form - Getting last record value from database as dynamic default or initial value for form field
I'm new in Python/Django with basic understanding and moving my steps slowly. This is my first question in stackoverflow. I've learned a lot from the previously discussed posts. Thanks to all who asked questions and special thanks to all those who contributed to such helpful answers. I searched and read a lot and tried to understand but could not figure out my way ahead on the following issue. I have a form for Transaction entry with the following fields. ==> Date ==> Farmer_num ==> purchase_qty ==> tr_rate I need to enter many records (500+ for a date) with the same date and same price (tr_rate). Instead of selecting date from datepicker and writing price (tr_rate) on entry form every time, i want to get them as default/initial value when form loads for new entry. This will save my time as well as prevent from entering the wrong date and price. When the form loads, in the date field, I want the last entry date as initial/default date from Trans table.

Django Email Backend Failing when DEBUG = False
Has anyone experienced this issue where when DEBUG = True your applications can't send emails? I'm trying to set up a password reset email and a contact form and both work fine in development and in production as long as DEBUG = False, but as soon as it equals True the email backend breaks (this is especially frustrating because I can't use DEBUG to find the issue). My email config looks as follows: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'mail.privateemail.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = 'admin@programaticlearning.com' EMAIL_HOST_PASSWORD = 'CorrectPassword' DEFAULT_FROM_EMAIL = EMAIL_HOST_USER -
Bootstrap tabpanel isn't showed with django url view
I am working with Django 3.1 and Bootstrap 4. I am trying to implement a tablist with href pointing to django view. However, when I click the second tab, nothing happens. The expected behavior is that the response from the view function is rended in the content of the tabpanel. This is my code: template.html <ul class="nav tab-switch" role="tablist" id="profile-tabs"> <li class="nav-item"> <a class="nav-link active" id="user-profile-info-tab" data-toggle="pill" href="#user-profile-info" role="tab" aria-controls="user-profile-info" aria-selected="true">Profile</a> </li> <li class="nav-item {% if active_tab == 'research2' %} active {% endif %}"> <a class="nav-link" id="user-profile-research-tab2" href="{% url 'app:research_profile' %}" role="tab" aria-controls="user-profile-research2" aria-selected="false">Research</a> </li> </ul> <div class="tab-pane fade show pr-3" id="user-profile-research2" role="tabpanel" aria-labelledby="user-profile-research-tab2"> <div class="table-responsive"> <div class="main-panel col-12"> <div class="content-wrapper"> {% include 'templates/_research_list.html' %} </div> </div> </div> </div> The view.py include in the response the variable "active_tab", but for some reason, the tab content never is showed. Any help would be very appreciated. -
