How to add additional function to form submit button in Django
I have a form and a submit button for it, how can I add additional functionality to this button, like for example I want to call sendNotification function when submit button is pressed. I googled and so far understand that this can be done by adding "onclick" javaScript function to that Submit button but then I need to call sendNotification in javaScript which seems to me kind of doing stuff around the corner, so I was wondering if there is some way to add function call to Submit button directly? #updateProduct.html <h1 style="font-size: 20px; margin-left: 10px;" class="p-2"> Update Job </h1> <div class="container m-1"> <form id=form action="" method="post" enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <input type="submit" name="Save Changes" class="btn btn-success m-0" value="Save Changes"> <a class="btn btn-primary mt-0" href="{% url 'showProducts' %}" > Cancel </a> </form> <!--This button below separately works but can it be integreted to the submit button above--> <a href="{% url 'sendNotification' id email %}" class="btn btn-success" >Notify</a> </div> Below is the sendNotification function itself #views.py @login_required(login_url='sendNotification') def sendNotification(request, pk, email): product = Product.objects.get(id=pk) msg = EmailMessage() msg.set_content(product.description + " Here is the link for details: ZZZ+str(pk)+"/" ) msg['subject'] = product.name msg['to'] = email user = "XX@gmail.com" msg['from'] … -

The dynamic data in my Django project doesn't change after I change the data
My Django project is linked with dynamic data from my google sheet API. However, when I edit on my google sheet and reload the page, the data doesn't change accordingly. I have to manually reload the server to refresh all the changes. I used gspread and pandas to convert my google sheet into a list of dictionaries. I was advised that I am reading the google sheet once, outside the view handling function. That only gets executed once while Django is starting up, and then my data is "fixed". If I want to refresh the data on each request, I need to read it inside the view function that handles the request, but I don't understand how. The following is my views.py from django.shortcuts import render from django.http import HttpResponse from django.template import loader import gspread import pandas as pd import datetime from oauth2client.service_account import ServiceAccountCredentials scope = ['https://www.googleapis.com/auth/spreadsheets'] creds = { "type": "service_account", "project_id": "ringed-arcana-338821", "private_key_id": "c1b2438db2651b90b92e06974a08cd40da42c696", "private_key": "-----BEGIN PRIVATE KEY-----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\nnsJQT+FQEDXWjZk1FXo=\n-----END PRIVATE KEY-----\n", "client_email": "returnrecord@ringed-arcana-338821.iam.gserviceaccount.com", "client_id": "110831427047173795415", "auth_uri": "https://accounts.google.com/o/oauth2/auth", "token_uri": "https://oauth2.googleapis.com/token", "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs", "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/returnrecord%40ringed-arcana-338821.iam.gserviceaccount.com" } client = gspread.service_account_from_dict(creds) def CreateSheet(Return_record): sheet = client.open(Return_record).sheet1 return sheet from sheet2api import Sheet2APIClient sheet = client.open('Return Record 2022') sheet_instance = sheet.get_worksheet(0) mylist … -
How do I resolve this urllib3 issue when trying to get a forked django project up and running?
I have a fork of a django project I am trying to get up and running for my local development environment. When I run my requirements it chokes with ~ this message [Cannot install -r requirements.txt (line 28), urllib3[secure]==1.26.0, urllib3[secure]==1.26.1]... etc. (this error spans ~20 lines). So there are conflicting dependencies it says. I have tried removing the specific version declaration and same issue. And, I have tried running under sudo and same issue. It seems like overall there's a discussion around doing some sort of declaration that specifies less than and greater than versions of a package with this general notion that pip isn't great at sorting this sort of thing out on its own but most of that conversation seems a few years old and I'm unclear on how such a declaration should be properly configured. Is this a common issue others have experienced of late? The project is running on django 3.0.2 and I tried to force an update to django to 4.0.2 in the hopes that the issue centers there but that didn't seem to address it either. Thanks in advance for your help. -

Django exported csv rows values changed with commas
I have a website that has some radio buttons that depending on which one you click it downloads one database table or another. I have made a Django view and then an Ajax function in Javascript. For some reason when I select one of the radio buttons and hit the download button, all the values of the csv are changed with something like ",,,,,". Does anyone know why this happens? My views.py: def download_db(request, mode): #data = JSONParser().parse(request) #serializer = WordsTableSerializer(data=data) response = HttpResponse(content_type='text/csv') writer = csv.writer(response) if mode == 1: writer.writerow(['session_id', 'word1', 'word2', 'word3','distance_to_word12','distance_to_word13', 'distance_to_word23']) for word in WordDifferentTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="WordsDifferent.csv"' return response elif mode == 2: writer.writerow(['session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23']) for word in LogicAnaloguiesTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="ForLogicAnalogies.csv"' return response elif mode == 3: writer.writerow(['session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23']) for word in SimilarWInContextTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="ForSimilarWordInContext.csv"' return response elif mode == 0: writer.writerow(['session_id', 'word1', 'word2', 'word3']) for word in WordsTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="WordsTable.csv"' return response return JsonResponse({}, status=304) The Ajax function: $( "#downloadbtn" ).click(function() … -
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process (Python/Django)
I know this question has been asked quite a bit on here, however after trying a number of solutions I am unable to figure out how to fix this issue. I am downloading images from the Google Maps API to generate maps with and without markers. I am using django-cleanup to remove files when deleted from database however the old versions wont delete. Weirdly, django-cleanup works correctly and deletes the associated image when deleting from the Django Admin page but not when deleting the file directly i.e. in file explorer and says it is open in Python. It also deletes correctly when my local server is terminated as you would expect. Traceback is as follows: Traceback (most recent call last): File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django_cleanup\handlers.py", line 97, in run_on_commit file_.delete(save=False) File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django\db\models\fields\files.py", line 373, in delete super().delete(save) File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django\db\models\fields\files.py", line 105, in delete self.storage.delete(self.name) File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django\core\files\storage.py", line 304, in delete os.remove(name) PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\Ricki.Demmery\\Desktop\\dev\\acl_acousticapp\\src\\acl_ac ousticapp\\media\\projects\\9335\\gmaps_markers_5xDqMnc.png' The call in views.py is as follows: gmaps = GoogleMapsAPI() gmaps.location_img(prjID) My Google Maps class def create_styled_marker(style_options={},mkr_lat=0,mkr_lng=0): opts = ["%s:%s" % (k, v) for k, v in style_options.items()] return '|'.join(opts) + '|{mkr_lat},{mkr_lng}|'.format(mkr_lat=mkr_lat, mkr_lng=mkr_lng) … -
Django app on Google App Engine slows down after 15 requests
I deployed a Django app on Google App Engine Standard with a F4 machine. The API is doing some machine learning and the processing has a duration of around 4s in local (between 3.5 and 4s). For my use case, it would be ok to have also 4-5s delays with the deployed app. However, when I test the deployed app doing the same request multiple times, I saw that the first requests take 3-4 seconds, but after 10-15 iterations, they take around 8s. Here is the code I used to test my app: session = requests.Session() all_times = [] for i in range(50): try: t0 = time.time() resp = session.post(url_api, headers=headers, json=data) t1 = time.time() print(t1 - t0) all_times.append(t1 - t0) except Exception as e: print("Err", e) The results of the request durations are as follows: I wonder why there is this gap after 15 requests and why some points are way above the average 7-8s (e.g. 10s). I get the same pattern looking at the latency in the Google Cloud Console: What I tried I tried to change the autoscaling parameters, thinking that it could be because of the creation of instances. But I got the same pattern when … -
Python virtual environment interpreter not working on VPS
I have Django project migrated using git migration. I managed to push my work to a VPS project directory (Ubuntu 20.04) following this guide: user@host:/var/www/project.com I have installed the database, up and running, and established a NGINX server block. Now the only thing is to start to run the manage.py Now I can't figure out why python command isn't working: (env) user@host:/var/www/project.com$ python manage.py runserver Error: -bash: env/bin/python: No such file or directory -bash: env/bin/python3: No such file or directory which python returns: /usr/bin/python which python3 returns: /usr/bin/python3 using ls -l env/bin shows: python -> python3.10 python3 -> python3.10 python3.10 -> /Library/Frameworks/Python.framework/Versions/3.10/bin/python3.10
