Running test together fails, running test alone succeeds
I'm using pytest. Going through the tests with a debugger, running both test_joining_previously_entered_queue_returns_previous_queue_details and test_joining_queue_enters_correct_position together, test_joining_previously_entered_queue_returns_previous_queue_details succeeds but test_joining_queue_enters_correct_position fails at queue = get_object_or_404(Queue, pk=kwargs["pk"]) in the JoinQueue view, where the view throws a 404 If I run test_joining_previously_entered_queue_returns_previous_queue_details individually, then the test will pass no problem. What should happen is that create_company_one creates a Company object, which in turn creates a Queue object (shown in the overridden save method of Company). The associated Queue object does not seem to be created if test_joining_queue_enters_correct_position is run with the other test, but works if the test is run standalone Why does this happen and how can I fix it? test_join_queue.py def create_company_one(): return Company.objects.create(name='kfc') @pytest.mark.django_db def test_joining_previously_entered_queue_returns_previous_queue_details(authenticated_client: APIClient): create_company_one() url = reverse('user-queue-join', args=[1]) first_response = authenticated_client.put(url) first_data = first_response.data second_response = authenticated_client.put(url) second_data = second_response.data assert first_data == second_data @pytest.mark.django_db def test_joining_queue_enters_correct_position(factory: APIRequestFactory): """ Makes sure that whenever a user joins a queue, their position is sorted correctly based on WHEN they joined.

In django, can I prevent attacker from re-using a session from one domain to gain access to another domain?
I have a django project serving two different purposes. On one subdomain, let's call it public.example.com, I allow unprivileged users to access a portal to edit their profile and settings. On another domain, private.example.com, I give the user access to some management functions. I have the default django session cookie settings, so when I log in to public.example.com and then try accessing private.example.com, I get redirected to a login page. This is normal and expected because the browser will not send the session cookie to any domain other than public.example.com. If I copy the session cookie that is sent to public.example.com and tamper with the request made to private.example.com so that I send the public cookie to the private domain, django responds with a 200 OK answer and renders the page as if I am a user that has logged in to that domain. I can not find any documentation that tells me that sessions are limited to the domains that they originated from, other than the default browser behaviour of limiting cookies to their respective domains. Is it possible to prevent such unwanted access without serving the project on two different instances with two different databases? -
Slow dropdown menu for foriegn key
I have created a backend website and is in production. It is using jawsdb and one of my models have 15000 records. The problem is when I click on the dropdown list of another model in admin panel it to select a model, it takes too much time for the list to appear and the search bar on the dropdown list hangs as well while writing. Is it because of cheap heroku plans and jawsdb. I could nt have messed up in the code. -

How to print a form in PHP or django to already structured pdf?
all right? I have a doubt about how I can make a form in php or django in which the client completes it, then it is sent to the server and when I refresh the page, the pdf document will appear for printing. In this case, the pdf will already have a ready-made structure with gaps, these gaps will be filled in with the customer's information. I just need to fill out this form and print it later, if it is not necessary to save it on the server, no problem. -

Django - How to get object on another app model without direct relationship in the parent model?
I have a Profile model, Award model as child of the Profile model [which takes other award details like achievement detail], and a List_of_awards model as child of the Award model [which takes list of awards and a count of how may profiles has the specific award]. Award model is inline with the Profile model using Foreignkey and List_of_awards model as Foreignkey field in the Award model for the choices of awards. What I am trying to do is, display the List_of_awards in the Profile model. The idea originated when I was able to display the List_of_awards in the list_display of the Award model', so, I was trying to link List_of_awardsin theProfile` which has no direct relationship. class Profile(models.Model): first_name = models.CharField(verbose_name=_('First Name'), max_length=255, null=True, blank=True, ) middle_name = models.CharField(verbose_name=_('Middle Name'), max_length=255, null=True, blank=True) last_name = models.CharField(verbose_name=_('Last Name'), max_length=255, null=True, blank=True) .... class Award(models.Model): list_of_award = models.ForeignKey('system_settings.Ribbon', related_name='awards_ad_ribbon', on_delete=models.DO_NOTHING, verbose_name=_('Type of Award'), blank=True, null=True) achievement = models.TextField(verbose_name=_('Achievement')) profile = models.ForeignKey('reservist_profile.Profile', related_name='awards_ad_profile', verbose_name=_('Profile'), on_delete=models.DO_NOTHING, blank=True, null=True) def image_tag(self): from django.utils.html import format_html return format_html('<img src="/static/media/%s" title="" width="75" /> %s' % (self.list_of_award.image,self.list_of_award.award)) image_tag.short_description = 'Award' class Ribbon(models.Model): award = models.CharField(verbose_name=_('Award'), max_length=255, null=True, blank=True) award_desc = models.TextField(verbose_name=_('Description'), max_length=255, null=True, blank=True) image = models.ImageField(verbose_name … -

Data is shown before form submission in Django 4.1
community! My goal is to create an app, which takes some user input, does machine-learning stuff and shows the results. I want to know whether the result was correct for each prediction. That's why I'm trying to implement a feedback system, where a user could mark the answer as "correct" or "incorrect" if one wants to do so. To be exact, I have two buttons: "the prediction looks like true" and "the prediction was incorrect". After clicking on one of these buttons I have a pop-up dialog shown with 3 checkboxes, where a user can provide additional information (it is not required). forms.py with these checkboxes looks like this: from django import forms class checkboxForm(forms.Form): is_winner_reason_true = forms.BooleanField(required=False, label="The first place in importance coincides with reality", label_suffix='') is_top5_reason_true = forms.BooleanField(required=False, label="Top 5 includes friends with high importance", label_suffix='') is_other_reason_true = forms.BooleanField(required=False, label="Other", label_suffix='') class checkboxFormFalsePred(forms.Form): is_winner_reason_false = forms.BooleanField(required=False, label="The other person should come first in importance", label_suffix='') is_top5_reason_false = forms.BooleanField(required=False, label="Top 5 includes friends with low importance", label_suffix='') is_other_reason_false = forms.BooleanField(required=False, label="Other", label_suffix='') I want to get data from clicking on one of two buttons (the value will be either True or False) and then, if a user decided to … -

How to reuse properties from table with django?
oke.

Like: mammals: cats, dogs, cattles. And then you have the animal it self: cats: siamese cat, ragdoll, etc. My question is: how can I resuse this properties for the three objects? So AnimalGroup subgroup animal So that a user can enter in the admin panel of django: mammals fish reptils and then can enter cats and choose from dropdown mammals.

And send the data to the model table. It is necessary that the data be saved in such a way that the city corresponds to the country to which the user wrote it down in the form. This is then used … -

django.db.utils.IntegrityError: and django.db.utils.OperationalError:
raise integrityerror( django.db.utils.integrityerror: the row in table 'hazeapp_orderitem' with primary key '1' has an invalid foreign key: hazeapp_orderitem.product_id contains a value '5' that does not have a corresponding value in hazeapp_newarrival.id.enter image description here I am trying to build 2 different models that include different product with their prices, name etc and render those two model products in two different template using for loop. But while creating an OrderItem model which includes both above foreign model leads to integrity error mostly.

get foreign key related data in django using filter
This is the model : class Requirement(models.Model): name = models.CharField(max_length=100) user = models.ForeignKey( User,on_delete=models.CASCADE, related_name = 'user' ) assigned_user = models.ForeignKey( User,related_name = "assigned",on_delete=models.CASCADE, ) I am running this query: requirementsOb = Requirement.objects.filter(user = currentUser) Where currentUser is logged in user. The result returns multiple requriements. I also want to get all user related data. How can i get user related data?
