How to get Simple JWT to work for all users in a django project (Not just super user)?
I've been using Simple JWT when making a project involving Django REST backend and React JS frontend. My authentication was going well until I realized that I am only getting a token when the user is a Super User in the Django app. Any other user account simply results in {"detail":"No active account found with the given credentials"} In some form another, when I try it via logging in from React, on my token/obtain page in Django, and in a curl script through command prompt. The user is labelled as active within Django admin Is there a setting I am missing? Here are my current JWT settings in settings.py: SIMPLE_JWT = { 'ACCESS_TOKEN_LIFETIME': timedelta(minutes=10), 'REFRESH_TOKEN_LIFETIME': timedelta(days=14), 'ROTATE_REFRESH_TOKENS': True, 'BLACKLIST_AFTER_ROTATION': True, 'ALGORITHM': 'HS256', 'SIGNING_KEY': SECRET_KEY, 'VERIFYING_KEY': None, 'AUTH_HEADER_TYPES': ('JWT',), 'USER_ID_FIELD': 'id', 'USER_ID_CLAIM': 'user_id', 'AUTH_TOKEN_CLASSES': ('rest_framework_simplejwt.tokens.AccessToken',), 'TOKEN_TYPE_CLAIM': 'token_type', } -
Looping through a list of attirubutes from Django
Basically, I've learned this far that coding something the right way means you shouldn't have to copy and paste a lot.. At least from what I've read. I basically need to assign my Django model points based on a boolean statement. If True add points otherwise dont add points. The point values will change but for now I have them set as 1. I can either copy/paste as many of these are I have to record scores for or I can see if there's an easier way, so ultimately thats my question, is there an easier way? scores_bool = { 'spc': 1, 'medical': 1, 'photo_id': 1, 'presolo_test': 1, 'presolo_checkout': 1, 'endorsement_solo': 1, 'solo': 1, 'dual_xc': 1, 'inst_training': 1, 'dual_night': 1, 'tol_tower': 1, 'solo_xc': 1, 'solo_xc_150': 1, 'checkride_prep': 1, } if ppl.spc: ppl.points += scores_bool['spc'] if ppl.medical: ppl.points += scores_bool['medical'] if ppl.photo_id: ppl.points += scores_bool['photo_id'] if ppl.presolo_test: ppl.points += scores_bool['pre_solo_test'] So basically each ppl attribute has a True False statement, if true add the points to it...etc Ideally I would loop through the scores_bool.keys() and say something like: for i in scores_bool.keys(): if ppl.i: ppl.points += scores_bool[i] Thankyou! -
In Django how to convert an uploaded pdf file to an image file and save to the corresponding column in database?
I am creating an HTML template to show the cover of a pdf file(first page or user can choose one). I want Django to create the cover image automatically without extra upload. The pdf file is uploaded using Django Modelform. Here is the structure of my code models.py class Pdffile(models.Model): pdf = models.FileField(upload_to='pdfdirectory/') filename = models.CharField(max_length=20) pagenumforcover = models.IntegerField() coverpage = models.FileField(upload_to='coverdirectory/') form.py class PdffileForm(ModelForm): class Meta: model = Pdffile fields = ( 'pdf', 'filename', 'pagenumforcover', ) views.py def upload(request): if request.method == 'POST': form = PdffileForm(request.POST, request.FILES) if form.is_valid(): form.save() return redirect('pdffilelist') else: form = PdffileForm() return render(request, "uploadform.html", {'form': form}) def pdfcover(request, pk): thispdf = get_object_or_404(Pdffile, pk=pk) return render(request, 'pdfcover.html', {'thispdf': thispdf}) In the 'pdfcover.html', I want to use the Django template language so I can render different HTML for different uploaded pdf files. That's why I want to save the image file to the same column as the pdf file. I am new to Python, new to Django, and obviously new to stack overflow. I have tried pdf2image and PyPDF2 and I believe they all could work however I just cannot find the right code. If you guys enlighten me I will be thankful. -
Views/ forms / models. Can someone help me in it?
I tryed to add validation to ContactModel, by doing Forms.py but I went too far away with it and now dont know to fix it. Can someone help ? def addContact(request): form = ContactForm() if request.method == 'POST': form = ContactForm(request.POST) if form.is_valid(): # form = Contact( # full_name = request.POST ('fullname'), # relationship = request.POST ('relationship'), # email = request.POST ('email'), # phone_number = request.POST ('phone-number'), # address = request.POST ('address'), # ) form.save() return redirect('/contact') context = {'form': form} return render(request, 'contact/new.html', context) def contactProfile(request,pk): contact = Contact.objects.get(id=pk) return render(request, 'contact/contact-profile.html', {'contact': contact}) In my opinion in Views I have big mess..

Successfully deployed Django to Heroku but received application error
My application works fine on Django local server. It deployed successfully to Heroku as well. But when I go to the website, it says application error. I see a bunch of H10 and H14 error codes. I've tried updating the Procfile without the initial space. I've tried deleting and re-adding the requirements.txt file. Maybe it's something with the static files? One SO solution said delete a bunch of things from requirement.txt file that you don't need - as that worked for them. I just don't which ones to delete. I can't add my Heroku logs --tail - SO thinks recognizes it as spam. If needed, I can email it to you.

Google analytics for Django app only shows root domain instead of page titles
I've got my first Django app in production and would like to setup Google Analytics to see pageviews/timespent/etc by page title for the order flow. I've added the GA javascript to the of my base.html template with the hope that it would track each page with page title. However, when I look at Google Analytics, I only see page views by my root domain 'mysite.com', and I cannot get get page views by '/app/pagetitle1', '/app/pagetitle2', '/app/pagetitle3', etc. 'app' is the Django app that the root domain gets redirected to 'mysite.com/app'. I'm assuming that Google Analytics would show entire path after root domain, if it were to work. It seems like there is probably something simple I've overlooked, and would appreciate any advice. Here's the GA tag I put in base.html right after per GA instructions: <!-- Global site tag (gtag.js) - Google Analytics --> <script async src="https://www.googletagmanager.com/gtag/js?id=XXX"></script> <script> window.dataLayer = window.dataLayer || []; function gtag(){dataLayer.push(arguments);} gtag('js', new Date()); gtag('config', 'XXX'); </script> Each template extends base.html as follows: {% extends "base.html" %} {% block content %} <section class="container container-interior"> etc - rest of <body> -
Issue with updating a dictionary in for loop (not unique)
I have an issue with populating a dictionary from the database. It overwrites or merges values that from my logic should be unique to the given country. country_dict = {'Netherlands': [{'Games': {}, 'Bikes': {}, 'Paint': {}}], 'Belgium': [{'Games': {}, 'Bikes': {}, 'Paint': {}}]} for country, value in country_dict.items(): for key in value: for category in key: for channel in channel_list: if channel in channels: aggr = item_obj.filter( order_fk__order_call_fk__ship_country=country, product__parent__product_category__product_category=category, order_fk__order_call_fk__channel=channel).aggregate(Sum('retail_price')) if aggr['retail_price__sum'] != None: key[category] = {channel: round(aggr['retail_price__sum'], 2)} which gives me if i print out line for line, exactly what i want see: Netherlands Games {'retail_price__sum': None} {} Bikes {'retail_price__sum': Decimal('30.1000000000000')} {'Channel #3': Decimal('30.10')} Paint {'retail_price__sum': Decimal('56.7000000000000')} {'Channel #1': Decimal('56.70')} Belgium Games {'retail_price__sum': None} {} Bikes {'retail_price__sum': Decimal('39.7000000000000')} {'Channel #1': Decimal('39.70')} Paint {'retail_price__sum': Decimal('13.9000000000000')} {'Channel #2': Decimal('13.90')} But when I print the final dictionary it overwrites the unique Netherlands values... { "Netherlands":[ { "Games":{ }, "Bikes":{ "channel #1": "Decimal(""39.70"")" }, "Sprays":{ "channel #2": "Decimal(""13.90"")" } } ], "Belgium":[ { "Games":{ }, "Bikes":{ "channel #1": "Decimal(""39.70"")" }, "Paint":{ "channel #2": "Decimal(""13.90"")" } } ] } if I use update() instead of = if aggr['retail_price__sum'] != None: key[category].update({channel.title+str(country): round(aggr['retail_price__sum'], 2)}) it merges the two together like this: { "Netherlands":[ { "Games":{ … -

Django how to set (return) default values for values_list if an object not exists?
I want to set an empty string for each field in specified values_list if the object not exists.

The object with id 3, NOT exists. Then we'll to have a list with 1 tuple. Then if some object(s) not exists, I want to return like this: [('obj_1_val_1', 'obj_1_val_2', 'obj_1_val_3'), ('', '', '')] -

I'll share with you my code: .computerScienceContent{ text-align: center; display: block; position: relative; margin-top: 10px; margin-bottom: 50px; width: 700px; margin-left: auto; margin-right: auto; padding: 30px; padding-left: 20px; animation-delay: 2s; animation: 1s linear 1s slideInLeft; } The above cod is used for displaying the block. This code is used to display it from left to right. @keyframes slideInLeft { 0% { transform: translateX(-100%); } 100% { transform: translateX(0); } } This is the django code from the html that I am trying to displaying with delay. <div class="computerScienceContent"> {% for cat in category %} <div class="csDivContent" id="slide"> <div id="slide"> <h4>{{ cat.name }}</h4> <img src="{{ cat.img.url }}" alt="image" class="img"> </div> </div> {% endfor %} </div> Basically, I want the block to be displayed 3 seconds after I access the website, one entry at a time, from left to right (there are only 4 entries). If anybody can help, I will be very happy! Thank you so much for your time ! -
Override Django model save method with many-to-many relations
I tryed to fill automatically field 'final_price' in model Cart but it doesn't change to nessasary value(in Admin) when I save it. But when I save created object again, it works. What should I do to save it immidiately when obj is created? class Cart(models.Model): owner = models.ForeignKey(User, verbose_name='Владелец корзины', on_delete=models.CASCADE) products = models.ManyToManyField(CartProduct, verbose_name='Продукты', blank=True, related_name='related_cart') total_products = models.PositiveIntegerField(default=0, verbose_name='Кол-во продуктов') final_price = models.DecimalField(max_digits=9, decimal_places=2, default=0, verbose_name='Общая цена корзины') def save(self,*args,**kwargs): if not self.id: super(Cart,self).save(*args,**kwargs) self.final_price = sum([fp.final_price for fp in self.products.all()]) super(Cart,self).save(*args,**kwargs) -
Method based admin filter
I would like to filter Events by a number of registered users. So I created method in EventAdmin class, which returns number of registered users. #admin.py @admin.register(Event) class EventAdmin(admin.ModelAdmin): list_display = ('name','registered_users') list_filter = ('registered_users') def registered_users(self, obj): link = reverse("event-users", args=[obj.id]) return format_html('<a href="{}">{}</a>', link, obj.user.all().count()) If I remove property “registered_users”from list_filter project works fine. But when I want to have also filter for registered users and I add “registered_users” to list_filter I get the following error: <class 'web.admin.EventAdmin'>: (admin.E116) The value of 'list_filter[1]' refers to 'registered_users', which does not refer to a Field. How can I solve this issue?
