Django returns NoReverseMatch instead of Updating the div with Ajax
Description I am creating a like button for a comment that was made on a post. When the user clicks on the like button, Django gives a NoReverseMatch and the page doesn't update automatically. After I refresh the page, it shows that the like was updated in the database, despite the NoReverseMatch error. What I tried? Initially, the issue was with the csrf_tokens. So, I added the csrf_exempt decorator, so it is definitely not the issue. I played a lot with the urls, and tried adding the comment id to the parameter, but it doesn't seem to help. Question How can I resolve the NoReverseMatch error and make it so that AJAX automatically changes the button from like to dislike. urls.py path('post/<int:pk>/like-comment', like_comment, name="like_comment") view.py @csrf_exempt def like_comment(request, pk): comment = get_object_or_404(Comment, id=request.POST.get('id')) liked = False if comment.likes.filter(id=request.user.id).exists(): comment.likes.remove(request.user) liked = False else: comment.likes.add(request.user) liked = True context = { 'comment': comment, 'is_liked': liked, 'total_likes': comment.likes.count() } if request.is_ajax(): html = render_to_string('blog/like_section_comment.html', context, request=request) return JsonResponse({'form': html}) main.js $(document).ready(function(event){ $(document).on('click', '#like-comment', function(event){ event.preventDefault(); var pk1 = $(this).attr('value'); // comment id var pk = $(this).attr('data-value'); // post id $.ajax({ type: 'POST', url: "like-comment", data: {'id': pk1, 'csrfmiddlewaretoken': '{{ csrf_token }}'}, dataType: … -

How to push single file in git
I want to push a single or few files to my website in git. I do it everytime by following way - git add (file) git commit -am "make it better" git push heroku master The problem is that git push heroku master also changes other things on my website by replacing it with old one, for example - "replacing admin objects with old one which is in django server".

Celery is not loading tasks from one app out of five
I'm using autodiscover in my celery.py file for gathering tasks. Which up until a recently picked all of the app.tasks.py up, I'm not sure why but my config.tasks.py function are no longer being picked up, but all the other apps are.

Form field defined in View does not appear in the returned `cleaned_data` dictionary
I am working on a reports page for a django app. This particular app (not written by me) has a reports page, where all report links appear with their forms. That is, if there is an updates timeline report page, it will appear here together with all of its form fields (time granularity, include security updates, etc) and a button that will take you to the updates timeline page to view the results (or chose different values). All other report links appear in this general page as well. Now to my problem: I want some specific, not required form fields to not appear in the general reports page, but instead only when the user accesses the actual report page. That is because they are ModelChoiceFields with thousands of entries, that slow down the rendering of the general reports page (there are many forms for different pages there, so it adds up). The way I do that is the following: I declare the fields as forms.HiddenInput in forms.py, and then inside my view, in the form_valid() function, I redefine the fields as ModelChoiceField. That way, the fields appear only when the user has submitted their first form (the one from the … -
How to save the choices in the save() in the model
I want to be able to save and retrieve the Choices , but depending on a certain value in the fields. For example, this is my model : class Business(TimeStampedModel): business_id = models.CharField( 'Business ID', max_length=64, unique=True, null=True, blank=True) legal_form = models.CharField( _('Legal form'), max_length=16, choices=LEGAL_CHOICES, blank=True) accordance = models.CharField( 'accordance', max_length=16, blank=True) def save(): radio_buttons = RADIO_BUTTON_SELECTIONS values = radio_buttons.get(self.legal_form) # What can I do here to ensure that wherever self.legal_form is different I save the value or I get the value saved Then my constants are as below : LEGAL_CHOICES = ( ('gbr', _('BGB-Society (GbR)')), ('ohg', _('Offene Handelsgesellschaft ')), ) RADIO_BUTTON_SELECTIONS = { 'gbr': (('yes', _('Yes')),), 'ohg': (('yes', _('YES')), ('no', _('NO'))), } As you can see the fields , I want to be able to change the Choices depending on the legal_form value, how can I do this in the save() method, or whats the best practice to achieve this ? -
Django 3: how to serve static images whose path is defined by a model attribute?
I'm trying to use images in Django 3 Debug mode as follows: on the admin side, get a list of the images contained in projects/static/img/ directory in the editing forms; on the front-end side, display the actual image of the class instance. Here's my code: settings.py STATIC_URL = '/static/' projects/models.py from django.db import models class Project(models.Model): img = models.FilePathField(path = 'img/') Images are located in the projects/static/img/ directory. When I create a new class instance with python manage.py shell: from projects.models import Project t = Project(img = 'img/test.jpg') t.save() The image gets displayed correctly on the front-end side. The problem is, I can't access the forms on the admin side. I get: FileNotFoundError at /admin/projects/project/add/ [Errno 2] No such file or directory: 'img/' I also tried python manage.py collectstatic that copies the projects/static/img/ folder into /static/img/ but nothings works, the admin side still gets the same error. Any suggestion on how to solve this? -

How to pass Sportsipy Python sports API through Django template

Im not sure how it is formatted or what the story with it is.screenshot of one of the endpoints in API docs -

Django Queryset filter for ForeignKey elements
I have a problem with building a custom queryset inside one of my views. Here is a simplified version of my models. The idea is that I want to track the price of different products in different shops. A shop can have multiple products and a product can be present in multiple shops. Products can have set an is_special flag to highlight them. The following structure was choosen because it easily allows adding new products and shops later on: class Product(models.Model): product_id = models.CharField(max_length=255, primary_key=True) is_special = models.BooleanField(default=False) product_name = models.CharField(max_length=255, default='', blank=False, null=False) class ShopProductPrice(models.Model): product = models.ForeignKey("Product", on_delete=models.CASCADE) shop = models.ForeignKey("Shop", on_delete=models.CASCADE, related_name="shop_entry") price = models.FloatField(default=0.0, null=False) class Shop(models.Model): name = models.CharField(max_length=255, default='', blank=False, null=False) location = models.CharField(max_length=255, default='', blank=False, null=False) These are my serializers: class ShopProductPriceSerializer(serializers.ModelSerializer): class Meta: model = Product fields = ['product', 'price'] class ShopSerializer(serializers.ModelSerializer): shopProductPriceData = ShopProductPriceSerializer(many=True, source='shopProductPrice_set') class Meta: model = Shop fields = ['name', 'location', 'shopProductPriceData'] And finally, here is the corresponding view where I want to use a custom queryset: class ShopViewSet(viewsets.ModelViewSet): queryset = Shop.objects.all() serializer_class = ShopSerializer def get_queryset(self): queryset = Shop.objects.filter(shopproductpricedata__product__is_special=False) return queryset The important point now is the get_queryset() function.

The register.js file is given below: console.log(“this is working”); And you know the output should be this is working but when I run this , the console look as that picture which is given below: browser console screenshot Even If I give full path such as <script> src= "/home/name/python/django/python test/app_name/static/js/register.js" </script> then also the issue is still remain . But if I give direct code like <script> console.log("this is test"); </script> then it perfectly worked. How can I solve this issue? -
How To Stop All Site Associated User From appearing In Post Model ForeignKey During Post Creation
The post logic was to allow all users on my site to be able to create post and news which is a success but unfortunately when creating a post all the whole user in the database appears for the particular authenticated user to choose from and this are information i don't want the user to see when creating post and i do not not plan to remove the user foreign key from the post since it helps me implementing other site critical functions and the author. because the user will serve as author class Post(models.Model): image = models.ImageField(upload_to="images/") title = models.CharField(max_length=150) summary = models.CharField(max_length=250) category = models.ForeignKey(PostCategory, on_delete=models.CASCADE) content = RichTextUploadingField() date_posted = models.DateTimeField(default=timezone.now) user = models.ForeignKey(User, on_delete=models.CASCADE) slug = models.SlugField(max_length=250, unique=True, blank = True) def onlyselfuser(self, *args, **kwargs): self.user = self.request.user super().onlyselfuser(*args, **kwargs) #please take a look at my view.py files class PostCreateView(LoginRequiredMixin, CreateView): model = Post fields = __all__ def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) i will appreciate if someone can show me a way out where the login user( user=request.user) will only appear excluding other users on moder and i tried a OneToOneField still and it didnt work. i Don't want to see all site … -
Adding context to django admin changelist_view
I'm trying to add some context to a Django admin view when the change list is displayed. I have this class class LeadStatSummaryAdmin(admin.ModelAdmin): change_list_template = 'admin/stats/leadstatsummary/change_list.html' def get_queryset(self, request): qs = super().get_queryset(request) query=Q() if 'from_date' in request.GET: from_date = datetime.datetime.strptime(request.GET['from_date'], '%d/%m/%Y').strftime('%Y-%m-%d') to_date = datetime.datetime.strptime(request.GET['to_date'], '%d/%m/%Y').strftime('%Y-%m-%d') query = Q(date_of_lead__gte=from_date, date_of_lead__lte=to_date) return qs.filter(query) def changelist_view(self, request, extra_context=None): response = super().changelist_view( request, extra_context=extra_context,) qs = self.get_queryset(request) response.context_data['date_form'] = DateForm(request.GET or None) response.context_data['data'] = qs. \ values('type_of_lead', 'may_contact_provider', 'type_of_care_care_home', 'type_of_care_home_care', 'type_of_care_live_in_care', 'type_of_care_retirement_village') \ .order_by('type_of_lead', 'type_of_care_care_home', 'type_of_care_home_care', 'type_of_care_live_in_care', 'type_of_care_retirement_village','may_contact_provider') \ .annotate(count=Count('type_of_lead')) return response This provides a date form I can use to filter the queryset. This runs fine when called from the menu (so no date form) but when I enter dates and submit I get this error 'HttpResponseRedirect' object has no attribute 'context_data' It is referring to this line of code response.context_data['date_form'] = DateForm(request.GET or None) I do not understand why this should be causing an error and how to fix. Can you help please -
