404 error on new pages with wordpress blog ( on mysql) with django (postgres) using nginx on the same server
Condition : I have set up my server as follows : my wordpress blog ( on mysql) with django (postgres) using nginx on the same server. Error I am getting 404 error for new pages I create on the blog. ( it works when permalink settings is like this : https://www.example.com/blog/?p=1 It does not work when permalink setting contains post name New pages I create also behave in similar fashion - do not work with name slug My analysis is that it has something to do with ssl conf or nginx conf.

How to get id from another table in django?
I am writing a script to populate database tables. I need to get foreign key from city table. There are 3 fields in the City table: id, name, reference. I need a foreign key for the Warehouses table with fields id, name,reference, city_id (foreign key). I take all the data from the API. def refresh_warehouses(): api_domain = 'https://api.novaposhta.ua' api_path = '/v2.0/json/Address/getWarehouses' api_data = { "modelName": "Address", "calledMethod": "getWarehouses", "methodProperties": { "Limit": "5" }, 'apiKey': settings.NOVA_POSHTA_API_KEY } response = requests.post(api_domain + api_path, json=api_data).json() if not response.get('success'): raise Exception(','.join(response.get('errors'))) Warehouse.objects.all().delete() warehouses = [] for item in response.get('data'): params = { 'name': item.get('Description'), 'reference': item.get('Ref'), 'city_id': City.objects.get(name=item.get("CityDescription")).id, 'delivery_method_id': 1 } warehouses.append(Warehouse(**params)) Warehouse.objects.bulk_create(warehouses) After executing the script, django throws a FOREIGN KEY constraint failed error. Tell me how best to take the id from the City table? -
How to get all items related to a Foreign Key in django?
My aim is to get all the items with a particular category from the model I created. For example, if I should get a category with an ID, I want to get all the products that is in that category. Below is my model class Product(models.Model): name = models.CharField(max_length=200) category = models.ForeignKey('Category', null=True, on_delete=models.SET_NULL) id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) def __str__(self): return self.name class Category(models.Model): #product = models.ForeignKey('Product', null=True, on_delete=models.SET_NULL) name = models.CharField(max_length=200, blank=True, null=True) id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) def __str__(self): return self.name Below is my view def getCategory(request, pk): category = Category.objects.get(id=pk) # product = Product.objects.all() products = Product.category_set.all() # Product.category_set.all() context = {'category': category, 'products':products} return render(request, '*.html', context) I tried using Product.category_set.all() and I have tried to flip it over, getting the products relaed to the category that I got the ID but I dont know how I can do that.

django: modelChoiceField form not working in template
I am confronted for the first time to a situation where I want the user to select model column values based on some constraint. The goal is to have the user select something and then output the result below the form on the same page. I am not sure what I am doing wrong but submiting the form output: Select a valid choice. That choice is not one of the available choices. Here is what I have been able to do: forms.py class SelectBuildingForm(forms.Form): filename = forms.ModelChoiceField(queryset=Building.objects.none()) def __init__(self, *args, **kwargs): us = args[1] or None forms.Form.__init__(self, *args, **kwargs) self.fields['filename'].queryset = Building.objects.filter(project=us).values_list('filename',flat=True) views.py @login_required @owner_required def FileSelectionView(request,pk): form = SelectBuildingForm(request.POST or None, pk) # if form.is_valid(): # filename = form.cleaned_data('filename') # print(filename) # return redirect('comparator_test') return render(request,'files_selection.html', {'form':form}) and template <div class="mt-5 md:col-span-2 md:mt-0"> <form method="POST" id="my-form"> {% csrf_token %} {{ form.as_p }} <button type="submit" value="Select">GOOOO</button> </form> {% if form.is_valid %} {% for choice in form.cleaned_data.choices %} <p>{{ choice }}</p> {% endfor %} {% endif %} </div> I have tried a couple options to validate the selection but none of them work. Can a pair of fresh eyes see where I am messing up? -
How can I call an asynchronous function inside my synchronous Consumer?
In my django quiz project I work with Channels. My consumer QuizConsumer is synchronous but now I need it to start a timer that runs in parallel to its other functions and sends a message after the timer is over. class QuizConsumer(WebsocketConsumer): def configure_round(self, lobby_id): # Call function to send message to begin the round to all players async_to_sync(self.channel_layer.group_send)( self.lobby_group_name, { 'type':'start_round', 'lobby_id':lobby_id, } ) self.show_results(lobby_id, numberVideos, playlength) def start_round(self, event): self.send(text_data=json.dumps({ 'type':'start_round', 'lobby_id': event['lobby_id'] })) def show_results(self, lobby_id, numberVideos, playlength): async_to_sync(self.channel_layer.group_send)( self.lobby_group_name, { 'type':'show_results_delay', 'lobby_id':lobby_id, 'numberVideos':numberVideos, 'playlength':playlength, } ) def show_results_delay(self, event): time.sleep(event['numberVideos']*event['playlength']+5) self.send(text_data=json.dumps({ 'type':'show_solution', 'lobby_id': event['lobby_id'] })) I tried to work with async functions and await, but I did not get it to work as I expected yet. I tried to work with async functions but so far it disconnected from the websocket or it did not send the "start_round" until the timer was finished. -

Django: mysterious slow request before timing middleware kicks in
I'm using Django with Sentry to monitor errors and performance. There's one specific endpoint (this doesn't happen with other endpoints) that seems to stall for a few seconds before actually processing the request. It's a very simple endpoint, but it does get called a lot. It seems to do nothing for a few seconds and is waiting on the time before Django middleware is even called. The actual logic that goes into rendering only takes a few hundred milliseconds: something is happening before the Django middleware that causes this to only happen for this view. What could this mean? I don't often see the Django.db.close_old_connections call and I'm hoping someone might have a clue for what might be causing it when the stall is after that, with another stall in the same place towards the end right before close_old_connections is called again. -

How to accept a file upload in django and send it to a flask api as a file upload?
I have a Flask API running on my localhost that accepts a file as a form data and returns an output. I also have another application that is created using Django that actually faces the user. I'm trying to have it so that a user can upload a file to the Django app and the Django app then forwards the file to the API.

How to trigger a python script on the server through user action in react (Django+React)?
I'm trying to launch a python script on the backend when a user enters some numbers into a form using react. I have Django as the main "shell" for my app handling the backend and is pointing to React properly for the frontend. The idea is to run all complex mathematical models, big data processing, and calculations on Python in the backend while node.js is used to run only front-end UI related scripts. Django for substance, React for the aesthetics. I am able to use SpawnSync child_process in Node.jus to successfully execute when I type "node run_python.js" in the command line ("run_python.js" is the name of my function). But when I run "npm run dev", that's when node is saying it can't find child_process. I checked node_modules and the childprocess library is there with keywords "child_process" included in the pacakge.json. I also tried referencing "child_process" in the main package.json file as a dependency. Is there a better way to trigger a python script on the server through action in react? -

How to get the value from a template in Django to pass it to another template?

Does chaining prefetch_related fetch all sub-queries?
Take this for example: user = User.objects.prefetch_related("foo__bar__baz").get(id=id) In this scenario, do I not need to do: user = User.objects.prefetch_related("foo__bar").get(id=id) if I want to access values on bar, or if they are mixed between select_related and prefetch_related due to some being OneToOne and others being FK like this below? user = User.objects.prefetch_related("foo__bar__baz").select_related("foo_bar_baz_qux").get(id=id) Or would skipping the prefetch and only using select be sufficient? user = User.objects.select_related("foo_bar_baz_qux").get(id=id)
