I am trying to run a custom sql query in django on an sqlite3 database and get an operational error when I try and pass more than one parameter into my sql statement. I'm not sure why, I've tried using cursor.fetchall() instead of namedtuplefetchall but that didn't work. My database is named cardholders.sqlite3 and I have a table also name cardholders that I'm trying to pull data out of. below is the relevant code from django.db import connections from collections import namedtuple def namedtuplefetchall(cursor): "Return all rows from a cursor as a namedtuple" desc = cursor.description nt_result = namedtuple('Result', [col[0] for col in desc]) return [nt_result(*row) for row in cursor.fetchall()] then some views in between @login_required def databaseTest(request): if request.method == 'POST': postid = request.POST.get("id") with connections['cardholders'].cursor() as cursor: cursor.execute("SELECT * FROM %s WHERE ID = %s",['cardholders',postid]) row = namedtuplefetchall(cursor) cursor.close() return render(request, 'LibreBadge/databaseTest.html', context = {"AlertMessage":AlertMessage.objects.all, "row":row}) row = "none" else: return render(request, 'LibreBadge/databaseTest.html', context = {"AlertMessage":AlertMessage.objects.all}) and the traceback Environment: Request Method: POST Request URL: http://localhost:8000/databaseTest/ Django Version: 3.0.5 Python Version: 3.8.2 Installed Applications: ['LibreBadge', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles'] Installed Middleware: ['django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware'] Traceback (most recent call last): File "/home/micah/.local/lib/python3.8/site-packages/django/db/backends/utils.py", line … -

Is there an equivalent of 'list_editable' for FileFields in django?
I'm making a website with django where you can basically upload a file to the django admin and download it whenever you need to view it. Very simple (making it for my dad which wants to organize his excel files for his work). This is the problem, I hard coded the download path to the file I uploaded, which makes me have to modify the path every time I upload a new file with the same name (since django adds a random string of digits and characters every time you upload a file with the same name as before). What i'm currently doing is really inefficient, and would like to change that as soon as possible. My idea is to make the FileField name editable in the django admin. I've come across this: list_editable = ['asd']. I thought that might work and so I tried it. The results were interesting. I immediately saw a 'Save' button on the bottom of the admin site, which wasn't there before. But I still couldn't edit the FileField. I've searched this on multiple forums, the django documentation and more forums, only to not find anything useful. This is a picture of how the admin … -
Django models: Access to a multilevel link between tables
I have a problem to access certain data in my models. I have a User model giving its id to a Profile model which is giving its id to a ProfileA model. And when I create a User it automatically creates a Profile.

What's the right procfile / requirements for heroku with django channels?
tl;dr - django channels app runs local with manage.py runserver but not on heroku. I'm new to django channels - trying to deploy a very basic django app using channels to heroku. I initially built the project using the standard django polls tutorial and deployed that to heroku. Then i added in a chat app using the django channels tutorial. Managed to get that running fine locally using docker to run a redis server as they suggested and "python manage.py runserver". I'm getting stuck trying to deploy this to heroku or run it locally using heroku local. I've already added the redis addon in heroku and modified settings.py to point to the REDIS_URL environment variable. I also modified my template to use wss if appropriate (I believe that's necessary for heroku): var ws_scheme = window.location.protocol == "https:" ? "wss" : "ws"; var target = ws_scheme + '://' + window.location.host + '/ws/chat/' + roomName + '/'; const chatSocket = new WebSocket( target ); ... Thus I'm concluding that the problem is with the procfile. I'm not sure what the instructions to use there are. The initial polls tutorial used: web: gunicorn gettingstarted.wsgi --log-file - If I just use that 'heroku local' … -

Best way to make a instance of mongodb client in pymongo

The problem is the following: from pymongo import MongoClient from bson.json_util import dumps class MongoConnector: username = 'user' password = 'pass' host = 'localhost' port = '27017' url = host + ':' + port client = MongoClient(mongo_url,username=username,password=password,authSource='admin',authMechanism='SCRAM-SHA-256') def find(self,db, collection, name): db = client[db] collection = db[collection] response = collection.find_one({"name":str(name)}) return dumps(response) I got it from: https://stackoverflow.com/a/55638199/11449132 The point with this piece of code is that I can put it into some file of my project and then, import the class to my API endpoints and do the db interaction, like creating instance of the MongoClient. It looks easy to work with, but my questions are: ¿Is it safe? ¿Does it have some problem with uwsgi or something related to production? like the threads, multiprocessing or something, I mean, I've read some documents and questions about but is not clear it all, for example: https://api.mongodb.com/python/current/faq.html?highlight=wsgi#using-pymongo-with-multiprocessing I know pymongo doesn't work with fork, but I'm not sure if it is important in this escenario.

Does 'list_editable' work with FileField in the django admin?
I'm trying to find a way to rename my uploaded files in the django admin using list_editable. I tried it, but it doesn't seem to be working, since it only shows a 'Save' button below, but nowhere where I can edit my files names. Is this even possible or does it not work with FileFields? I looked it up on forums but nothing to help my case. Thanks in advance! -

Files not uploaded in Django form - encoding type incorrect
We use Django with Crispy forms in our websites. I have a form rendered by {% crispy form %}. Here is the code of the form: class ProfileForm(AddAttributesToFieldsMixin, CleanDateOfBirthMixin, LocalizedFirstLastNameMixin, forms.ModelForm): profile_picture = forms.ImageField(required=False, widget=CustomPhotoWidget, label=_('Update your profile picture'), error_messages={'required': _("A profile picture is required.")}) class Meta: model = User fields = ('slug', 'gender', 'date_of_birth', 'profile_picture') The form uses CustomPhotoWidget which is defined like this: class CustomPhotoWidget(forms.widgets.Widget): def render(self, name, value, attrs=None, renderer=None): return render_to_string(template_name='accounts/edit_profile/widgets/photo_widget.html', context={ 'name': name, 'user_photo': self.attrs['user'].photo, }) But the problem is, when I upload a file from my browser, I receive an error message "No file was submitted. Check the encoding type on the form." and the file is not saved. The encoding type of the form is incorrect. How do I change the encoding type with Crispy forms? -

I have a custom throttle class like: (print statements are for debugging :)) in api.throttle.py print("befor CustomThrottle class") class CustomThrottle(BaseThrottle): def __init__(self): super().__init__() print("initializing CustomThrottle", self) self._wait = 0 def allow_request(self, request, view): print("CustomThrottle.allow_request") if request.method in SAFE_METHODS: return True # some checking here if wait > 0: self._wait = wait return False return True def wait(self): return self._wait my api.views.py is like: from api.throttle import CustomThrottle print("views module") class SomeView(APIView): print("in view") throttle_classes = [CustomThrottle] def post(self, request, should_exist): # some processing return Response({"message": "Done."}) and my tests is api/tests/test_views.py: @patch.object(api.views.CustomThrottle, "allow_request") def test_can_get_confirmation_code_for_registered_user(self, throttle): throttle.return_value = True response = self.client.post(path, data=data) self.assertEqual( response.status_code, status.HTTP_200_OK, "Should be successful", ) @patch("api.views.PhoneConfirmationThrottle") def test_learn(self, throttle): throttle.return_value.allow_request.return_value = True response = self.client.post(path, data=data) self.assertEqual( response.status_code, status.HTTP_200_OK, "Should be successful", ) the first test passes correctly but still the CustomThrottle class is instantiated but the allow_request method is mocked; the second test shows that neither CustomThrottle class is mocked nor the allow_request method and it fails with status 429 (CustomThrottle has a throttle rate of 2 minutes). -
django: css files not loading in production with nginx
I have seen many similar posts but nothing has been able to make the trick for me. Browser throws me this kind of error for all my css files when i load my static.

How do I allow users of Django to create their own personal blog?
I have created a Django site that allows users to post and comment on these posts. I thought it would be a good idea to allow each user to have their own "page" where they can allow invited members this page to basically use the blog feature that I've designed. The only thing I can't figure out is how to allow users to dynamically create a page that is specific to them. Can this be done with one template? -
