Django - LogoutView - cache_control - browser's back button has the logged out user's cache
Django 2.1.7 This is for a simple blog with homepage (post list view), post detail view, and profile (post list view) When a user logs out, LOGOUT_REDIRECT_URL = '/' redirects the user to the homepage. However, when the user clicks the browser's back button, the previous page still shows all the logged out user's data. When I reload the page, it clears the cache. when the user's logged in, shows username] when the user's logged out, shows 'login' I found a similar question and their answer was to use the cache_control decorator. Django - User re-entering session by clicking browser back button after logging out @cache_control(no_cache=True, must_revalidate=True, no_store=True) @login_required Would I have to add these decorators to every single view? I do not want the @login_required decorator. AnonymousUsers should be able to view all pages without logging in. What's the best way to do this? Similar to Twitter's logout flow. (user logs out -> login page -> back button -> previous page but reloaded) urls.py from django.contrib.auth import views as auth_views urlpatterns = [ path('logout/', auth_views.LogoutView.as_view(template_name='users/logout.html'), name='logout'), -
Integrating Razorpay Payment Gateway with Django causing CSRF verification failure
This question was previously asked here but I didn't have 50 reputation points to continue the discussion on that answer itself. Short version Essentially, the problem boils down to - I have an external URL that sends POST data to my Django application. I want to access this POST data but Django is giving 403 error (CSRF Token missing). Detailed version I am trying to add Hosted Payment Gateway of Razorpay to my Django Project. I have passed the URL to the following function in the callback functionality. As specified in the previous answer, I tried using the csrf_exempt decorator and adding the https://api.razorpay.com URL as CSRF_TRUSTED_DOMAINS in the settings.py file, but the issue still remains. I am still getting the 403 error from Django when the payment is successful. @csrf_exempt def course_purchase_callback(request): payment_id = request.POST.get("razorpay_payment_id") order_id = request.POST.get("razorpay_order_id") signature = request.POST.get("razorpay_signature") client = razorpay.Client(auth=(os.getenv("RZP_ID"), os.getenv("RZP_SECRET"))) verify = client.utility.verify_payment_signature({ "razorpay_payment_id": payment_id, "razorpay_order_id": order_id, "razorpay_signature": signature, }) settings.py file .. .. .. CSRF_TRUSTED_ORIGINS = ["https://api.razorpay.com"] .. .. Versions being used: Django = 4.0.3 Razorpay API = 1.3.0 What is the thing I am missing here? -

How to define columns from dictionary keys with Django tables 2?
I would like to create a table from multiple objects from a Django model called MyModel. The data are stored in a JSONField called weights with datetime as key like this {"2022-05-01T05:00:00Z": 0.123}. The name of the column should comes from a CharField called name. As you can see in the code below I iterate through the objects and create a Pandas Series to extract value and populate a dictionary.

django rest save api to bd
My task is to accept a post request with a link to a public api, and then save the data from json to my database, and display the last entry (before adding). I do all this in django rest. The problem is that I do not understand how to make a working serializer that accepts a link. Model serializer: class QSerialaizer(serializers.Serializer): color = serializers.CharField() age = serializers.CharField() Function that returns api by url: def j_request(url): response = requests.get(url) data = json.dumps(response.json(), sort_keys=True, indent=4) return(data) And finally, the function that I can't get is the post request in the view: def post(self, request): queryset = Cats.objects.all() data = request.data num = data['url'] for item in jservice_request(url): Question.objects.create( color=item['color'], age=item['age'] ) return Response({'queryset': queryset}) Is it necessary to use a serializer to create an entry in the database, and how to do it? -
is it possible to have two parameters in limit_choices_to in django models?
I'll shorten the code as simple as possible. Supposedly, we do have two models. models.py > Products table CATEGORY = ( ('Hard Disk Drive', 'Hard Disk Drive'), ('Solid State Drive', 'Solid State Drive'), ('Graphics Card', 'Graphics Card'), ('Laptop', 'Laptop'), ('RAM', 'RAM'), ('Charger', 'Charger'), ('UPS', 'UPS'), ('Mouse', 'Mouse'), ('Keyboard', 'Keyboard'), ('Motherboard', 'Motherboard'), ('Monitor', 'Monitor'), ('Power Supply', 'Power Supply'), ('Router', 'Router'), ('AVR', 'AVR'), ('Tablet', 'Tablet'), ('System Unit', 'System Unit'), ('Audio Devices', 'Audio Devices'), ('CPU', 'CPU'), ('Others', 'Others'), ) class Product(models.Model): model_name = models.CharField(max_length=100, null=True, blank=True) asset_type = models.CharField(max_length=20, choices=CATEGORY, blank=True) date = models.DateField(null=True, blank=True) And the other table > Order table class Order(models.Model): product_order = models.ForeignKey(Product, on_delete=models.CASCADE, null=False) employee = models.ForeignKey(User, models.CASCADE, null=False) date = models.DateTimeField(auto_now_add=True) remarks = models.TextField() And we all know that adding this code will limit the foreignkey choices under the Order form. limit_choices_to={"asset_type": "Hard Disk Drive"} limit_choices_to={"asset_type": "Solid State Drive"} My goal here is to show items from Products table whose asset_type is either "Hard Disk Drive" OR "Solid State Drive". I've read the documentation of Django for "limit_choices_to" and can't see any pertaining to some kind of solution in here. Thank you in advance who knows a way to make this possible. -

i followed the lesson to make a user register using Django, he made this code, like what I have made: class CustomUserForm(UserChangeForm): username = forms.CharField( widget=forms.TextInput(attrs={'class': 'form-control my-2', 'placeholder': 'Enter Username'})) email = forms.CharField( widget=forms.TextInput(attrs={'class': 'form-control my-2', 'placeholder': 'Enter The Email'})) password1 = forms.CharField( widget=forms.PasswordInput(attrs={'class': 'form-control my-2', 'placeholder': 'Enter The Password'})) password2 = forms.CharField( widget=forms.PasswordInput(attrs={'class': 'form-control my-2', 'placeholder': 'Confirm Password'})) class Meta: model = User, fields = ['username', 'email', 'password1', 'password2'] when run the server this errors displayed: PS E:\osamaStartup> py manage.py runserver Watching for file changes with StatReloader Performing system checks...

Styles not loading in Django
I have a site that needs some custom styles in Django and I can't get the static file to load. I have a static folder inside my main folder - The one where manage.py lives, Inside there is a CSS folder that contains a style.css. At the top of base.html, I load {% load static %} Then in the head of my HTML I load <link rel="stylesheet" href="{% static 'css/styles.css' %}"> and in my settings.py file I have loaded in # Static file route STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), ] When I load I just get a blank CSS file and no styles load, I'm fairly new to Django so please be kind, and thanks in advance. -
Allow empty foreign key selection in admin forms
i created a model(AnalysisFieldTemplate) with a foreign key to AnalysisFieldRule. What i want is to have the possibility to leave the field display_analysis_field_rule blank and save my admin form. class AnalysisFieldRule(models.Model): action_kind: str = models.CharField( choices=ActionKind.choices, default=ActionKind.DISPLAY, max_length=text_choices_max_length(ActionKind), verbose_name=_("action kind"), ) formula: str = formula_field() name: str = models.CharField(max_length=MAX_NAME_LENGTH, verbose_name=_("name")) def __str__(self): return f"{self.name}: {ActionKind(self.action_kind).label}" class Meta: constraints = [ UniqueConstraint(fields=("action_kind", "name"), name="%(app_label)s_%(class)s_is_unique"), ] ordering = ["name", "action_kind"] verbose_name = _("analysis field rule") verbose_name_plural = _("analysis field rules") class AnalysisFieldTemplate(models.Model): display_analysis_field_rule: AnalysisFieldRule = models.ForeignKey( AnalysisFieldRule, blank=True, limit_choices_to={"action_kind": ActionKind.DISPLAY}, null=True, on_delete=models.PROTECT, related_name="display_analysis_field_templates", verbose_name=_("display rule"), ) Now here is the problem. If i try to save my admin form without choosing one a value for display_analysis_field_rule it will result in an Validationerror. It seems that the standard empty value for a foreign key "------" is not a valid choice. @admin.register(AnalysisFormTemplate) class AnalysisFieldTemplateAdmin(admin.ModelAdmin): fieldsets = ( ( None, { "fields": ( "name", "name_for_formula", "ordering", "required", "kind", "display_analysis_field_rule", "highlight_analysis_field_rule", ) }, ), ( _("Text options"), {"fields": ("max_length",)}, ), ( _("Integer options"), {"fields": ("min_integer_value", "max_integer_value")}, ), (_("Amount of money options"), {"fields": ("min_amount_of_money", "max_amount_of_money")}), ) I debugged a little deeper and found that the "to_python" compares the choosen value with pythons standard "empty_values" but of course … -
Djongo + Django + MongoDB not support chainning filter
I have two model: Content and Tag that have ManyToMany realationship Content(models.Model): tags = models.ManyToManyField(Tag, null=False, blank=False, related_name="tags") Tag(models.Model): slug = models.CharField(max_length=255, null=False, blank=False, unique=True) name = models.CharField(max_length=255, null=False, blank=False, unique=True) Notice that I'm using MongoDB and djongo connector to work with my db. Now I want to filter "All of content that have n specific tags", example: all of the content that have tags = ["Movie", "News", "Science"], suppose id of them is: 1, 2, 3 corresponding. I have used chaining filter. content.objects.filter(tags=1).filter(tags=2).filter(tags=3) but it return not found. Yep, of course contents that have id = [1, 2, 3] are available in my database. But when I migrate to MySQL and try again, it work and return a queryset that I expected.
