I keep getting this "OperationalError at / (2002, "Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)")" after django deploy
I keep getting this "OperationalError at / (2002, "Can't connect to local server through socket '/run/mysqld/mysqld.sock' (2)")". I only turned DEBUG to True since to see what the error is and since I'm only the one currently accessing it. This is my first deployment of a django app. I've tried checking for the socket path, I can't find any folder called run. I think mysqld is in C:/Program Files/MySQL/MySQL Server 8.0/bin but when i tried setting C:\Program Files/MySQL/MySQL Server 8.0/bin/mysqld.mock it as my socket it didn't work either. I'd really appreciate the help -
How to use Exception in python?
I wrote code below. def get(self, request): ... try: ... ... food = Food.objects.get(food_id="red") if food: data = { "name" : food.name, } res.append(data) return JsonResponse({"success": res}, status=200) except Exception as e: return JsonResponse({"failed": e}, status=403) My intention is, I would like to go to exception and get 403 if there is no food. However, in this case, if there is no 'food' data, a 500 error (DoesNotExist) occurs. Why do I get this error? Am I misunderstanding the concept of exception? -
Django returns session id but doesn't authenticate user

Copy content from an html tag in a file to a tag in another html file
all in peace? In Django, I need the content of an HTML tag to appear in another template. Using the code JS: <script> var source = document.getElementById("teste").innerHTML; document.getElementById("texto").innerHTML = source; </script> <div id="teste">context</div> <div id="texto"></div> It even works in the same template, but if the destination tag is in another template, it doesn't work. Any idea? -
How to filter some words in a queryset
I have a variable, which contains stock symbols. I need to split each symbol, to compute it independently. print(Symbols_Splitted) #returns this ["'['AAPL", 'TSLA', "MSFT']'"] I need something to filter the relevant words, the pattern is always the same. I tried this, which works but I find out an issue. Some symbols have special characters in them like "EURUSD=X", and this code remove the "=" which makes it not valid. def convertor(s): perfect = re.sub('[^a-zA-Z]+', '', s) return perfect all = list(map(convertor, Symbols_Splitted)) So, by taking the first example I need something like this: Some_function(Symbols_Splitted) Symbols_Splitted[0] > AAPL Symbols_Splitted[1] > MSFT Symbols_Splitted[2] > TSLA -

Django, How to clear the previous data model thoroughly?
I'm viewing my admin site, but in the Add Groups page, I can still see the available permissions that I have deleted before. and in my models.py I haven't configured any of these table yet.

UpdateView form_valid is not redirecting as expected - keeps saying form_valid?
I've got a Django UpdateView that I am trying to test against. The UpdateView only accepts post requests, handles the form and redirects the user appropriately depending how the form submission went. The test fails, but if I run the local server, it works as I would expect. I'm not sure if it's an indication that my test is setup wrong - or if the test is exposing some weird bug. My view looks like this: class TressleUpdateView(UpdateView): http_method_names = ["post"] form_class = TressleForm model = Tressle pk_url_kwarg = "tressle_id" raise_exception = True def form_valid(self, form): """ This method is called when valid form data has been POSTed.

How can I install React and Python packages on a single DigitalOcean App?
I have a Django project with a ReactJS application (index.html) directly integrated into the Django template system. This is an alternative way of integrating Django and React where you can have shared authentication and have your React app seamlessly display within the template (look and feel) of the Django website. One issue you must overcome is getting your DigitalOcean environment built so that it includes all the packages and dependencies for Python, Django, and NodeJS/React. The DigitalOcean platform does not include any specific instructions on accomplishing this complete setup. I've struggled to find answers here too. -

Issues deploying Django app to AWS web server
I would like to complete the Django first app but instead of accessing it via the local host on my machine. Id like to access it through a free tier on AWS. This is for an Education tool I am presenting to a class. Im wondering if anyone has done this, or if there is any videos/guides for this? I would also like to have a number of students working on this as well so it would be great if there was also a guide for explaining to the students how to use Docker, pull the container to their local machines (all students will be using VSC as their IDE). The end goal is for the base app to be developed on their local machines (macOS/Windows/Linux etc). When they commit their code to the repo, for it to deploy to an AWS web sever (free educational tier account) for them to see their changes. Then if the changes are good, they can deploy to the "production" server. If these are not the normal steps of the deployment pipeline, might someone clarify for me? Thanks for any assistance! -
Where to define custom data handling for a m2m field in django
Let's say for example I want the many to many 'tags' modelfield to be inputted as a space-separated list, were an unrecognized name be submitted it should also be created in the 'Tag' model. I'm aware this could be written either at: View level Form level FormField level ModelField level I want to adhere to the DRY principle as tightly as possible. For the time being I have defined it at ModelForm level but my setup is not very flexible. I would have to write new forms for every variation in each part of the website I place this formfield in. -

I have a model tickets, with a sum in it. I'm trying to make spending tickets by nearest expire date. But if I'm ordering by date_expire, it move date_expire=None models to the top. But date_expire=None means that ticket has no limit by time, and should be used after all tickets, that has time limit. My code: ticket = Tickets.objects.filter( sum__gte=0, date_expire__gte=timezone.now(), user_id=user.id, burned=False ).order_by( 'date_expire' ).first() I can try to sort by sorted func with lambda key, but I think there's a better way to do this in orm
