Show number of objects in Many to Many Relationship? (Django)
I have a simple blog created in Django with Posts and Comments for each post. I'm trying to show the total number of comments for each post on the home page but I can't get the total to show. Here's my model: class Post(models.Model): user = models.ForeignKey(User, on_delete= models.CASCADE) title = models.CharField(max_length=100, blank=False) content_text = models.TextField(blank=False, max_length=3000) created_date = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title class Comment(models.Model): user = models.ForeignKey(User, on_delete= models.CASCADE) post = models.ForeignKey(Post, on_delete= models.CASCADE) content_text = models.TextField(max_length=500) created_date = models.DateTimeField(auto_now_add=True) My views.py: def home(request): posts = Post.objects.all() return render(request, 'post/home.html', {'posts': posts}) And lastly my html file: {{ post.comments.count }} The other information displays correctly such as {{post.title}}. Any ideas what I'm doing wrong? Thanks! -

Template for Carousel not showing context variable
I have made a Slider Model which contains 3 images and Texts related to it to slide in a Carousel My problem is that I want these images to be shown from the newest to oldest. If I remove the {% if sliders %} {% for slider in sliders %} the latest image only appears because in the views it is filtered by .latest('timestamp') I have also tried to replace .latest('timestamp') in the views with .all() it still didn't work This is the model: class Slider(models.Model): title = models.CharField(max_length=60) image = models.ImageField(blank=False, upload_to='Marketing') header_text = models.CharField(max_length=120, null=True, blank=True) middle_text = models.CharField(max_length=120, null=True, blank=True) footer_text = models.CharField(max_length=120, null=True, blank=True) button_text = models.CharField(max_length=120, null=True, blank=True) active = models.BooleanField(default=False) timestamp = models.DateTimeField(auto_now_add=True, auto_now=False) def __str__(self): return self.title def get_image_url(self): return "%s/%s" % (settings.MEDIA_URL, self.image) I've had help with the view which is as follows: class HomeView(ListView): model = Item paginate_by = 10 template_name = "home.html" def get_context_data(self, **kwargs): context = super(HomeView, self).get_context_data(**kwargs) try: context['marketing_message'] = MarketingMessage.objects.filter( active=True).latest('timestamp') except MarketingMessage.DoesNotExist: context['marketing_message'] = None try: context['slider'] = Slider.objects.filter( active=True).latest('timestamp') except Slider.DoesNotExist: context['slider'] = None return context This is the template: {% if sliders %} {% for slider in sliders %} <div class="carousel-item {% if forloop.first … -
CSS file isn't applying to the page, not loading under sources
I was trying to link a css file to my html, and for some reason the css won't load in. Below I'll supply the html and css code. When I open the page source, the css href works fine, I can click on it and it takes me to the css file, but when I inspect I can see that the css file is not part of sources. I've tested my code on JSFiddle and it works fine there, as well as on the snippet here. I also tried pressing ctrl + f5 and shift + f5 to refresh the page without caches, but nothing changed. So I don't know what else to do to fix this. I've been doing it on Chrome so I tested it real quick on Firefox but still, no changes.

Join two sets of data of the same table in django
I want to select two sets of data from the same table and them join them using a common field class modelA(models.Model): year = models.IntegerField() week = models.IntegerField() sales = models.IntegerField() pillar = models.IntegerField() I want two select data from the (for example) week 8 and 9 of the year, then join them using the corresponding pillar so i get something like this: Using sql i think it should look like this, but i don't know how to translate that to django select * from ( select * from data where year = 2020 and week = 8 ) as A join ( select * from data where year = 2020 and week = 9 ) as B on A.pillar = B.pillar -
usage of ('/') in the following django code
I started a todo app tutorial and having a problem into fully understanding code in this part of it: def index(request): tasks = Task.objects.all() form= TaskForm() if request.method == "POST": form = TaskForm(request.POST) if form.is_valid(): form.save() return redirect('/') ''' just the part which used redirect('/') , what is the meaning of this sign (( ('/') )) and if you could explain to me why is it important to specify for the app that if the request method is POST do the following moves? -
Save successfully validated form fields when other fields fail
I have a rather long form including validation which I would like users to fill out. If the user submits the form successfully then it is saved to the db. I am aware that some users may attempt to submit the long form, only to have it raise validation errors, then leave my site and return to complete it later. I would like the form fields which are successfully validated to be saved (or is it possible to have them save automatically without the user needing to press the submit button?) so if the user exits the site they can later return and only have the fields which failed validation blank, not the entire form. views.py def needs_analysis(request): if request.method == 'POST': form = PersonalInformationForm(request.POST, request.FILES, instance=request.user.personalinformation) if form.is_valid(): form.save() return redirect('enrolment-index') else: form = PersonalInformation(instance=request.user.personalinformation) context = { 'form' : form } return render(request, 'enrolment/personal_info.html', context) Thank you. -
"FieldList" with foreign objects
Let's say I have cars running in different races. I want an ordered list in Race with the cars that will run. The problem is I want to manually modify that list from admin interface. class Car(models.Model): id = models.CharField(max_length=16, primary_key=True) class Race(models.Model): title = models.CharField(max_length=255) start_grid = models.ForeignKey(Car,on_delete=models.CASCADE) I have read many posts about ordering on related ForeignKey based on some filters like creation date or so, but this particular case requires to define a manual order. Don't exist some kind of models.ListField so my solution is to create a list of related Car ids and store JSON string in Race. But feeling that is not a good idea How can I create a field that contains an ordered list of foreign objects/id and be compatible with modify the order from admin interface? -

Django non-static content not rendering
I'm using kubernetes and containers. nginx ingress controller. Also nginx container is serving up static content. The landing page (static) works just fine (checked with incognito, no caching). Soon as I go to a page that requires rendering something from the backend, it times out. I logged into the containers and cannot see any immediate issues in the log files or elsewhere. I shut down all the containers and started them fresh. Still nothing from the Django side is responding. Here is my nginx config (in Kubernetes/yaml format): apiVersion: v1 kind: ConfigMap metadata: name: nginx-config data: nginx.conf: | events { worker_connections 1024; } http { server { access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; listen 8080; server_name localhost; location ^~ /.well-known/acme-challenge/ { default_type "text/plain"; } location /static/ { autoindex on; alias /code/core/static/; include /etc/nginx/mime.types; } location = /favicon.ico { access_log off; log_not_found off; } location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://127.0.0.1:8080/; } } } I can't tell what the issue is.

Django REST User Creation/Authentication

Django Serializer showing "character": "Dictionary object (256)" as opposed to the actual character
I am using Django rest framework and I am trying to do a JOIN on a GET command. I have the following view: class CharacterView(APIView): permission_classes = (AllowAny,) def get(self, request, user_id): character_saves = Char.objects.select_related('character').filter( user_id=user_id) serializer = CharacterSerializer(character_saves, many=True) return Response({"characters": serializer.data}) And the following serializer: class CharacterSerializer(serializers.Serializer): character_id = serializers.IntegerField() user_id = serializers.IntegerField() active = serializers.BooleanField() character = serializers.CharField() def create(self, validated_data): return Char.objects.update_or_create( user_id=validated_data.pop('user_id'), character_id=validated_data.pop('character_id'), defaults=validated_data ) Yet, I am getting the following data: "characters": [ { "character_id": 256, "user_id": 1, "active": true, "character": "Dictionary object (256)" }, { "character_id": 260, "user_id": 1, "active": true, "character": "Dictionary object (260)" } ] Instead of giving me the actual item I want, it gives me a dictionary object. This is almost correct, however I am guessing I am configuring something wrong in my query or serializer, preventing me from getting the raw value. How do I get the actual value here, rather than "Dictionary object (260)"? -

How can i add multiple models and custom fields to a json response in Django Rest Framework

Pass args and kwargs into reverse Django

However, if I add another variable into args here: reverse('page', args=(key, more_data)) then it gets messed up as it tries to open a url at: page/<key>/<more_data> Furthermore, django doesn't allow args and kwargs in one reverse call. How would I pass data in then? Thanks! -

jQuery: Saving a form with jQuery turns the form invalid
I'd like to save a form containing an image. Without jQuery the form saves as intended, however, adding below "js-product_image-create-form" function creates an invalid form, but, at the same time, json respond status is: <JsonResponse status_code=200, "application/json"> The form is invalid in the View (prints "invalid" below) and in "invalid" in jQuery. However, removing the class="js-product_image-create-form", visually I get json with a valid form = True as well as the function prints "valid" Why is the form valid in one case but invalid in the other case? Using Django View: def save_product_image_form(request, form, template_name): data = dict() if request.method == 'POST': if form.is_valid(): form.save() data['form_is_valid'] = True print("valid") product_image = ProductImage.objects.all() data['html_product_image_list'] = render_to_string('product_image/includes/partial_product_image_list.html', { 'product_image': product_image }) else: data['form_is_valid'] = False print("invalid") context = {'form': form} data['html_form'] = render_to_string( template_name, context, request=request) return JsonResponse(data) def product_image_create(request): if request.method == 'POST': form = ProductImageForm(request.POST, request.FILES) else: form = ProductImageForm() return save_product_image_form(request, form, 'product_image/includes/partial_product_image_create.html') $(function() { var saveForm = function() { var form = $(this); $.ajax({ url: form.attr("action"), data: form.serialize(), type: form.attr("method"), dataType: 'json', success: function(data) { if (data.form_is_valid) { alert("I am valid"); $("#product_image-table tbody").html(data.html_product_image_list); $("#modal-product_image").modal("hide"); } else { alert("I am invalid !"); $("#modal-product_image .modal-content").html(data.html_form); } } }); return false; }; …
