Django 3: Unable to generate dynamic object view
I have successfully created the expected structure for my model and in the error variables I can see that the DB object was returned but I am not able to resolve the page. I am getting error " TypeError at /ticket-edit/2 - init() got an unexpected keyword argument 'instance'" - am I referencing the object incorrectly? Is there an approach allowing appTicketID=appTicketID (I use aTicketID instead but the DB field is appTicketID)? In the error the local var shows that the expected ticket was retrieved: Variable: Value aTicketID: '2' context: {} obj: <Ticket: 2 2021-10-06 Ticket Title Ticket Desc> request <WSGIRequest: GET '/ticket-edit/2'> Urls.py (I use URL instead of path to generate the ID link) urlpatterns = [ url(r'^ticket-edit/(?P<aTicketID>\d+)', views.ticket_edit, name='ticket-edit') ] Models.py class Ticket(models.Model): #---Base Meta----------------------------------------- appTicketID = models.AutoField(primary_key=True) date_submitted = models.DateTimeField( max_length=20, auto_now_add=True) issue_title = models.CharField(max_length=90) issue_description = models.CharField(max_length=1000) def __str__(self): return (f"{self.appTicketID} " f"{self.date_submitted} " f"{self.issue_title} " f"{self.issue_description} " def get_absolute_url(self): return reverse_lazy('ticket-edit', kwargs={'aTicketID': self.appTicketID} Views.py @login_required def ticket_edit(request, aTicketID): context = {} obj=Ticket.objects.get(appTicketID=aTicketID) updateform=TicketForm(instance=obj) if aTicketID == None: aTicketID = 1 aticket = Ticket.objects.filter(appTicketID=aTicketID) print('\n-----------------------------------------------------------------') print('TicketFiltered: ', aticket) print('-----------------------------------------------------------------\n') context = { "has_error": False, "updateform": updateform, "aticket": aticket } return render(request,'appname/ticket-edit.html', context) -

Django warnings "Not found XXXX" when re-rendering html pages
I collect html from search engine result pages (baidu, sogou, Google, Bing) and use Django to re-render them. It is successful when rendering pages from Baidu or Sogou, but for pages from Google or Bing, there are lots of warnings about "not found XXX". For example, in rendering Bing pages, some warnings: [21/Oct/2021 22:15:44] "GET /sa/simg/Roboto_Regular.woff2 HTTP/1.1" 404 2484 Not Found: /s/ac/25308934/MsnJVData/HoverTranslationV2.css [21/Oct/2021 22:15:44] Not Found: /th "GET /th?id=OVP.amkWCd5lEnKAiv3c6hEoiQEsCo&w=197&h=110&c=7&rs=1&qlt=90&o=6&pid=1.7 HTTP/1.1" 404 2508 Not Found: /th [21/Oct/2021 22:15:44] "GET /rp/4q26YP9oX8_7FiOTRx6BpR60bSg.png HTTP/1.1" 404 2502 Not Found: /fd/ls/lsp.aspx I have more own scripts for these rendered pages such as adding some popup windows. I also tested my script on static pages and it worked. However, when rendering the page, my script didn't work at all, so I wonder if these warnings hold my own scripts. I am looking for a way to ignore or skip these warnings. -

sock failed (111: Connection refused) while connecting to upstream using nginx + uwsgi for django

Django access file by path in FileSystemStorage
I'm trying to use virus totals api to scan a uploaded file to django website, i'm using the Djangos FileSystemStorage to store the uploaded files. I have set the Media path to /media/ in settings MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') and tested adding a url for the uploaded files and it was accessible at /media/{{file name}} eg through www.domain.com/media/{{file name}} urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Although when i attempt to access this file within script to attach to a request i receive the file not found at this directory error. to get the path i am currently using the fs.url(name) command which returns /media/{{file name}} I understand the FileStorageSystems /media/ path does not actually exist within the folder suggested eg app/media is there a alternative command to retrieve the true path? or do i need to use a different storage system for this purpose? thanks Current Script uploaded_file = request.FILES['file'] # getting file from form fs = FileSystemStorage() # initlize FileSystemStorage name = fs.save(uploaded_file.name, uploaded_file) # Save Uploaded file to storage params = dict(apikey=API_KEY) # add api key for request with open(fs.url(name), 'rb') as file: # context manager opening saved file files = dict(file=(fs.url(name), file)) # create dict of … -

ReactJS: Javascript fetch works on desktop browsers but returns a 403 error which says (authentication credentials not provided) on IOS safari
I'm working on a project using Create-react-app with a backend API written in Django(Python) where I used fetch to make my API calls. API calls run fine on android browsers and on desktop browsers but on IOS Browsers(both safari and chrome) the API returns the 403 error with response (authentication credentials not provided). this issue is a bit more tasking for me as it is quite difficult for me to perform remote debugging for IOS using my windows PC. I was only able to view the error due to JavaScript console using chrome://inspect on IOS and consoling the API response to the Iphone's console I would like some help on this issue. -

Incorrect response from .get_or_create function in Django
I have been trying to understand why the .get_or_create function I'm using isn't working. It's supposed to find the object in the DB with matching parameters and create a new one if none are found. When running this, it always says that there are not matching objects and the tuple return True every time hence always creating a new object (a duplicate). This causes the Except statement to run every time as well. Here is my function: for desktop in desktops: try: clean_location = serialized_location_information(desktop) clean_machine = serialize_machine_information(desktop) location_name, location_created = Location.objects.get_or_create( latitude=clean_location["latitude"], longitude=clean_location["longitude"], provider=clean_machine["provider"], defaults={ "country": clean_location["country"], "state": clean_location["state"], "city": clean_location["city"], "street_address": clean_location["street_address"], "postal_code": clean_location["postal_code"], "name": clean_location["name"], "status": clean_location["status"], } ) if l_created: logger.info(f"New Location was created successfully") except Exception as ex: logger.error(f"Could not get or create location: {ex}") location = None pass Here is my model: class Location(models.Model): class Meta: unique_together = ['latitude','longitude','provider'] latitude = models.DecimalField(max_digits=9, decimal_places=6) longitude = models.DecimalField(max_digits=9, decimal_places=6) country = models.CharField(max_length=100, blank=True) state = models.CharField(max_length=25, blank=True) city = models.CharField(max_length=250, blank=True) street_address = models.CharField(max_length=250, blank=True) postal_code = models.CharField(max_length=100, blank=True) name = models.TextField(blank=True) status = models.PositiveSmallIntegerField(default=10, choices=LocationStatus.CHOICES) provider = models.ForeignKey(Provider, on_delete=models.CASCADE, default= '') def __str__(self): return f"{self.name}" -
One dictionary key is overriding the others. Dictionary is being accessed at definition
I am experiencing an odd issue where 21 of the dictionary keys work correctly. However, when this specific 22nd one is added, things stop working correctly.

Django3 Nginx Gunicorn Supervisor not logging error

How to show data from views on chartjs in django?
I am making an app on Django at the moment and I don't know how to get the data from views to the chart properly. Here's my code for views: def data(request): nysestuff = nyse.objects.all() riskappstuff = riskapp.objects.all() feargreedstuff = feargreed.objects.all() putcallstuff = putcall.objects.all() feargreednm = [float(feargreedstuff[i].Fear_Greed/100) for i in range(len(feargreedstuff))] outputdata = [(float(nysestuff[i].NYSE_Up_Vol) + feargreednm[i] + float(putcallstuff[i].Put_Call) + float(riskappstuff[i].Risk_App))/4 for i in range(len(feargreedstuff))] yesno = [outputdata[i] > 50 for i in range(len(outputdata))] labels = [str(nysestuff[i].Daily_NYSE) for i in range(len(nysestuff))] context= { 'outputdata': outputdata, 'labels': labels, 'yesno': yesno } return render(request, 'newapp/index.html', context=context) I want to get outputdata and labels into the chart. Here's my code for the html: <!DOCTYPE html> <h1>Trial page</h1> <body>{{labels}}</body> <html lang="en"> <head> <!-- Required meta tags --> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!--Chart js--> <title>Sample Graph</title> <script src="https://cdn.jsdelivr.net/npm/chart.js@3.5.1/dist/chart.min.js"></script> </head> <canvas id="myChart" width="200" height="100"></canvas> <script> var ctx = document.getElementById('myChart').getContext('2d'); var myChart = new Chart(ctx, { type: 'bar', data: { labels: {{labels}}, datasets: [{ label: '# of Votes', data: {{outputdata}}, // backgroundColor: [ // 'rgba(255, 99, 132, 0.2)', // 'rgba(54, 162, 235, 0.2)', // 'rgba(255, 206, 86, 0.2)', // 'rgba(75, 192, 192, 0.2)', // 'rgba(153, 102, 255, 0.2)', // 'rgba(255, 159, 64, 0.2)' // ], … -
Cleaned_data coming as empty data in django form?
I have a form field and it is a form.JsonField(). When I am submitting data,and logging the data received in the cleaned_data, it always outputs the empty data. Reason being, when I log the request.POST, I can see the incoming data is coming as list e.g <Querydict:{"name":["test",'']. When I pass request.POST to my form, I always get self.cleaned_data.get("name") as empty. It always gives me the last item from the list value. Possible solution in my mind, is to manipulate the request.POST data before sending to form and then everything will work fine. e.g update_request = request.POST.copy() updated_request['name'] = updated_request.getlist('name')[0] Now, I can pass this to my form e.g form = MyForm(updated_request,instance=self.get_sample()) Point is this seems more like a hack compared to a clean solution. Is there a more efficient way to do this instead of hacking all this in the views. -
How can I solve this DJANGO_SETTINGS_MODULE or call settings.configure() problem?
I'm currently learning to use Django with a Udemy course that is pretty outdated but since it was the best rated I thought I'd give it a try. After covered how to set the models.py file they showed how to use Faker to populate the admin section with fake data. The problem arises when trying to run this populate file, this is what shows up: django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. This is my populate file from faker import Faker from first_app.models import AccessRecord, Webpage, Topic import random import django import os os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings') django.setup() # FAKE POP SCRIPT fakegen = Faker() topics = ['Search', 'Social', 'Market', 'News', 'Games'] def add_topic(): t = Topic.objects.get_or_create(top_name=random.choice(topics))[0] t.save() return t def populate(N=5): for entry in range(N): # get the topic for the entry top = add_topic() # create the fake data for that entry fake_url = fakegen.url() fake_date = fakegen.date() fake_name = fakegen.company() # create the new webpage entry webpg = Webpage.objects.get_or_create( topic=top, url=fake_url, name=fake_name)[0] # create a fake access record for that webpage acc_rec = AccessRecord.objects.get_or_create( name=webpg, date=fake_date)[0] if __name__ == '__main__': print('populating script..') populate(20) …
