I'm trying to use if inside the for loop in Django, but it keeps getting into the else part.

Ajax and Django Like button
I made a like button with Ajax and it works, but only when I click on the 1st post, the like_count counter updates the instant value. The like_count value does not change after clicking the button for the 2nd and subsequent posts. ** When I click on the like button of the second and subsequent posts, I see a change in the like_count value of the first post. When I refresh the page, I see that the value of the 2nd and subsequent posts has changed.** My problem is that I want the like count value to change instantly for the 2nd and subsequent posts. could this be the problem (id="like_count") myviews.py @login_required(login_url="login") def like(request): if request.POST.get('action') == 'post': result = '' id = request.POST.get('postid') post = get_object_or_404(Post, id=id) if post.likes.filter(id=request.user.id).exists(): post.likes.remove(request.user) post.like_count -= 1 result = post.like_count post.save() else: post.likes.add(request.user) post.like_count += 1 result = post.like_count post.save() return JsonResponse({'result': result, }) mybutton.html {% if request.user.is_authenticated %} {% if post.like_count >= 2 %} <button style="margin-top: 10px;" class="btn btn-light like_button_true like-button" value="{{ post_item.id }}"> <img style="width: 32px; height:32px;" src="{% static 'img/likeTrue.png' %}" /> <br> <span id="like_count">{{post_item.like_count}}</span> </button> {% else %} <button style="margin-top: 10px;" class="btn btn-light like_button_detail like-button" value="{{ post_item.id }}"> <img … -
Prefetch with few filters
There is a table Order, which is connected to table Signal through FK. I loop through the records from table Signal and access the child elements from table Order. As a result, I get N+1 query.

django - saving list of base64 images
i have a django and django restframework project with postgres as database. so i send a payload from frontend to this django project and this payload is json and have one field named images. images is contain list of base64 images. so i want to save them in database and i use code below for this field: images = ArrayField(base_field=models.ImageField(upload_to='hotel_images/')) but when i want to save images i get this error: images: ["The submitted data was not a file. Check the encoding type on the form."] i understand that i have to decode base64 so that i can save them in imageField but how should i do that? how can i decode base64 this images in list one by one? or do you know a better way for this? this are some of my codes: serializer.py class HotelsSerializer(serializers.ModelSerializer): class Meta: fields = ("id", "name", "stars", "address", "description", "number_of_floors", "number_of_rooms", "room_delivery_time", "room_empty_time", "images", "features") model = Hotel models.py class Hotel(models.Model): """ model for create a hotel """ name = models.CharField(max_length=60, unique=True) stars = models.IntegerField() address = models.CharField(max_length=150) description = models.TextField(default="nitro hotel") number_of_floors = models.IntegerField() number_of_rooms = models.IntegerField() room_delivery_time = models.TimeField() room_empty_time = models.TimeField() images = ArrayField(base_field=models.ImageField(upload_to='hotel_images/')) features = models.JSONField() def __str__(self) … -
send json from template to django view and then redirect to that view
I have a template cat1.html with a listing of products . When a customer selects an item, it builds an object with properties of the selected product. If the customer clicks 'add to cart' button, axios sends a request + params stringified product object to /cart ulElement.addEventListener('click', function(event) { let targetClasses = Array.from(event.target.classList); if(targetClasses.includes('dropdown-item')) { /* code to build the item */ } if(targetClasses.includes('btn-cart')) { axios.get('/cart', { params: { item: JSON.stringify(item) } } ); } }); so far this is working fine, I can print the object/json from the server so I know it makes it through. def cart(request): item_dict = json.loads(request.GET.get('item')) user_cart.append(item_dict) print(user_cart); # this seems to work fine /* return redirect('cart') this results in error TypeError(f'the JSON object must be str, bytes or bytearray, ' */ The problem happens when I try to add a redirect to the /cart view. I get the error the JSON object must be str, bytes or bytearray, not NoneType I've tried to get around this using window.location.href and also wrapping the button in an but I get the same error, so I get the sense I'm using the wrong approach. -
How to find the no of people following a hashtag - Django
I have used Django-Taggit in the posts to add tagging in my project. My post model schema is like this : class Feed(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE,related_name='feedposts') publish =models.DateTimeField(default = timezone.now) created = models.DateTimeField(auto_now_add=True) *** tags = TaggableManager() In order to make user follow the hashtags. I have added this field in the User Model Schema which looks like this. class Profile(models.Model): **** following_tags = TaggableManager() Then if the user follows the particular tag, I add that particular tag in the listed field. Now we can get the feed according to the hashtags user is following. But now I want to find out the total number of people following a particular hashtag and this is something I am not able to do. Also, Please tell me if there is any other implementation from which I can achieve this feature using django-taggit since it is easy without using it by just making a simple table of FollowedHashtags like below class FollowedHashtags(models.Model): name = models.CharField(unique = True) user = models.ManyTOManyField(User) We can get the no of people following the Hashtags: hashtag = FollowedHashtags.objects.get(id=1) nooffollowers = hashtag.user.count() I have tried some filtering queries but no success yet. So if know any other implementation … -
How to make a button show the appropriate message in Django?
I am trying to create asocial media type site that allows users to follow other users through a Django model. For some reason, the Follow Button says "Unfollow" when a user is not following the user and says "Follow" when the user is following the other user.

Django Foreign Key or ManyToMany is throwing an error
I am trying to connect two tables without success in Django. I have 2 models in my code: class IngredientFoodPortion(models.Model): food_code = models.ForeignKey(Ingredient, on_delete=DO_NOTHING, related_name="ingredients2") modifier = models.CharField(max_length=200, blank=True, null=True) gram_weight = models.DecimalField(decimal_places=6, max_digits=10, default=0) class MealIngredients(models.Model): meal = models.ForeignKey(Meal, on_delete=DO_NOTHING, related_name="details" , verbose_name='Meal Name', default='defaultMeal') ingredient = models.ForeignKey(Ingredient, on_delete=DO_NOTHING, related_name="ingredients" , verbose_name='Ingredients', default='defaultIngredient') serving = models.ManyToManyField(IngredientFoodPortion) amount = models.DecimalField(decimal_places=3, max_digits=10, default=0) the tables look like this: The issue is in this link: serving = models.ManyToManyField(IngredientFoodPortion) The way it should work is that if we choose the ingredient code (first column in screenshot), we should be getting back the 2nd & 3rd columns, which are usually multiple row. i tried both ForeignKey which failed because the FK is not unique, and ManyTOManyField as you can see. Any help would be appreciated. Thanks in advance, -
Update is_online field to true when user logs in
Building logic that, when a user logs in would change a boolean field in my Profile model to true and then turn that to false when the user logs out. The problem is I have an api_end point where I can see a list of all users and information related to said users.

Is there any way to have my html page refresh/reload itself after a function in the django view.py tab completes?
I want to have my page refresh itself after a successful download of a zip file since successive attempts to click the submit button result in an error, and the only way to remedy it fairly easily is to manually refresh/reload the page. I was wondering if there is a way to set it up so that once the zip is completed the page will refresh itself without the user having to worry about it. Doing it this way also kills two birds with one stone, since I want to disable the submit button to prevent users from spamming it, but if I end up having the page refresh I could just out right remove it after it's clicked.

Send list of filtered users to redis instance when function is triggered in frontend
Trying to create a function that when triggered in the frontend, will get a list of all users who are currently logged in and create key value pairs for all these users in my redis cache. This is what I am currently trying. I have this function in my views: def postToRedis(request): online_users = User.objects.filter(is_online='true').order_by('-date_joined') queue_of_users = { d['username'] for d in online_users } keys = list(queue_of_users.keys()) values = list(queue_of_users.values()) for i in range(0, len(keys)): redis_instance.set(keys[i], values[i]) response = { 'msg': f"{keys} successfully set to {values}" } return Response(response, 201) My intention here is to get a list of all users, filter for users who are online, get a list of all keys and correspondent values, loop through these lists and write each pair as a key value pair in my redis instance. I then have an API end point for my frontend to interact with my backend and trigger this function to run path("/post", postToRedis, name="postToRedis"), However when I try to trigger this function I do not get any of the desired output written into my redis_instance. Would love to get help on this -
Django AppRegistryNotReady when running another multiprocessing.Process
Problem I needed to run multiple UDP servers on different ports that exchange data with a Django core, so I defined a Django command which calls a method (start_udp_core) that runs each UDP server in a separate process. I used socketserver.UDPServer and stored the needed data for the socket using a Django model called ServerData. The Django version is 4.0.5 So I came up with this code: from core.models import ServerData from .data_receiver import UPDRequestHandler def create_and_start_server(host, server_data): with UDPServer((host, server_data["port"]), UPDRequestHandler) as server: try: logger.info(f"server is listening ... {server.server_address}") server.serve_forever() except KeyboardInterrupt: print("... going off ...") except Exception as e: logger.error(str(e)) def start_udp_core(): all_servers = ServerData.objects.values() logger.info(f"servers data ... {all_servers}") db.connections.close_all() default_host = "0.0.0.0" for server_data in all_servers: multiprocessing.Process(target=create_and_start_server, args=(default_host, card_data)).start() After running the command using manage.py, AppRegistryNotReady: Apps aren't loaded yet is being raised: INFO - start_udp_core - servers data ... - <QuerySet [{'id': 1, 'type_id': 1, 'ip': '192.168.0.50', 'port': 5000}, {'id': 2, 'type_id': 1, 'ip': '192.168.0.51', 'port': 5001}]> Traceback (most recent call last): File "<string>", line 1, in <module> Traceback (most recent call last): File "<string>", line 1, in <module> File "c:\...\python\python39\lib\multiprocessing\spawn.py", line 116, in spawn_main File "c:\...\python\python39\lib\multiprocessing\spawn.py", line 116, in spawn_main exitcode = _main(fd, parent_sentinel) File … -

How can I set an attribute to use in both POST and GET methods in django class-based views?
So I'm building a class-based view that uses data from a table on my db, both on POST and GET methods. I've been trying to set an attribute with the table to mitigate the time that it would take to pull the table again for the sake of performance. Because of how functions/methods work I can't set an attribute like this: class MyClass (View): @md(login_required(login_url='login',redirect_field_name=None)) def get(self, request): con = create_engine('mysql+mysqlconnector://user:password@localhost:8000/schema') #function to get a dict with db tables tabs = get_tables(con) #Trying to make the attribute self.table = tabs['table_That_I_need'] context{'data':tabs} return render(request, 'markowitz/markowitz.html',context) @md(login_required(login_url='login',redirect_field_name=None)) def post(self, request): #this gives me an error since the attribute was not set table = self.table form = MarkowitzForm(request.POST,table) if form.is_valid(): pass return render(request, 'markowitz/results.html') I've been trying to use setattr but it doesn't seem to be working -
Why adding FilteredSelectMultiple widget to ModelMultipleChoiceField form field is not posting values selected?
I've been stuck around this issue for a while now and no existing post helped me solve it. I have a form with the following field declared in my forms.py: class SignRequestForm(forms.ModelForm): dental_codes = forms.ModelMultipleChoiceField( label='Select Proccedure Codes', queryset = CDTADACodes.objects.all() ) And this is processed in the views.py as it follows: class CreateInsuranceView(CreateView): def post(self, request, *args, **kwargs): #Declare and process patient_valid object if request.POST.get('eligibility_type') != 'Orthodontic': patient_valid.save() patient_valid.dental_codes.set\ (CDTADACodes.objects.filter\ (pk__in=request.POST.getlist('dental_codes'))) patient_valid.save() which works as expected. The problem is that when i want to add the FilteredSelectMultiple widget to dental_codes field the field is no longer posted in the form Here is the forms.py with the widget applied: class SignRequestForm(forms.ModelForm): class Media: css = { 'all': ('/static/admin/css/widgets.css',), } js = ('/admin/jsi18n',) dental_codes = forms.ModelMultipleChoiceField( label='Select Proccedure Codes', queryset = CDTADACodes.objects.all(), widget = FilteredSelectMultiple('Dental Codes Selection', is_stacked=True) ) Finally this is the html template for the field INSIDE the <form>: <section> <div class="row justify-content-md-center"> <label>{{form.dental_codes.label}}</label> </div> <div class="row justify-content-md-center"> <div class="form-group" id="dental_codes"> {{form.media}} {{form.dental_codes.errors}} {{form.dental_codes}} </div> </div> </section> No errors are raised, it's just that in the request payload the field is no longer posted. Any help is more than welcomed, thanks in advance -
Can`t verify the email address with Django Rest and React
friend, I'm new and trying to figure it out. I have some problems with verification user via email. I have backend on 8000 port with Django rest framework and frontend on 3000 port with React. After registration I receive an email with link to submit email, like this: http://localhost:8000/activate/NDQ/b87jb3-6f86c3a304f606f584203f4d4e5ecfe8 If I click on this link, I receive an error Page not found (404). But if I change in address string Port on 3000: http://localhost:3000/activate/NDQ/b87jb3-6f86c3a304f606f584203f4d4e5ecfe8 verification submit and have no problem. What do I need to do to get verification through the link that comes in the letter, because there is port 8000, and the frontend has 3000
