Django administration Site. 'Delete multiple objects' produces ValidationError
When attempting to delete multiple rows, which have a one to one relationship with two other tables I received the following error: ['“March 21, 2022” value has an invalid date format.

Django testing - group object not working when using factory_boy
I'm trying to streamline my testing by using factory_boy. I would like to test views that depend on some group permissions. If I write my test by creating a user and group in setUpTestData, I can get the test to work. However, if I create the user and group using factory_boy, it doesn't look like the permissions are set in the test. view @method_decorator([login_required, teacher_required], name='dispatch') class GradeBookSetupCreateView(PermissionRequiredMixin, UpdateView): raise_exceptions = True permission_required = 'gradebook.change_gradebooksetup' permission_denied_message = "You don't have access to this." form_class = GradeBookSetupForm model = GradeBookSetup success_url = "/gradebook/" def get_object(self, queryset=None): try: obj = GradeBookSetup.objects.get(user=self.request.user) return obj except: pass The permission problem is from the PermissionRequiredMixin and permission_required. There is also a permission in the decorator but that is working fine. Here is a test that works: class GradeBookSetupTests(TestCase): @classmethod def setUpTestData(cls): cls.user = get_user_model().objects.create_user( username='teacher1', email='tester@email.com', password='tester123' ) cls.user.is_active = True cls.user.is_teacher = True cls.user.save() teacher_group, created = Group.objects.get_or_create(name='teacher') teacher_group = Group.objects.get(name='teacher') content_type = ContentType.objects.get( app_label='gradebook', model='gradebooksetup') # get all permssions for this model perms = Permission.objects.filter(content_type=content_type) for p in perms: teacher_group.permissions.add(p) cls.user.groups.add(teacher_group) cls.user.save() print(cls.user.groups.filter(name='teacher').exists()) my_g = cls.user.groups.all() for g in my_g: print(g) cls.gradeb = GradeBookSetupFactory(user=cls.user) def test_signup_template(self): self.client.login(username='teacher1', password='tester123') response = self.client.get(reverse('gradebook:gradebooksetup')) self.assertEqual(response.status_code, 200) … -

Rebase git branch upon 2 pull requests
I have a Django project with 4 other members, and I'm creating a model, let's call it "model M". Model M is having 2 foreign keys, the first is model A and the other is model B. At this moment, model A and model B are both not approved and merged to the main branch on our GitHub repo, and both on different pull requests, and I need to rebase my current branch of creating model M upon those 2 pull requests of A and B. I know I can rebase my branch on 1 pull request, but is it possible to rebase it upon 2 different pull requests? If so, how can I do it without having them rebase on each other (because they don't really rely on each other)? Thanks! I've rebased my branch on the first pull request, model A. But when I've tried to rebase the current branch on model B as well, I got conflicted (because they don't have the same commit history). -

Django - Performance checking permission in template
I have a template that is a header snippet that is used on every page of the platform. What I would like to know is what performance implications/issues checking permission with {% if perms.foo.add_bar %} can have on the platform. And if there is a better way to do this. I checked the load/request time of the page on Django Toolbar and didn't seem to change at all. Although I tested just at my local environment, not the production (don't have access). -

Can I create django-like auth app using FastAPI?
As I understand FastAPI is good for building APIs. However I was wondering, will I be able to create a Django-like web-app, say e-commerce app with accounts and cart, using FastAPI. I glanced at docs and couldn't find any kind of auth features, login/logout/signup, Forms validating that input etc. Is that available from the box or there are some libraries? Does it even make sense or it is better to use Django/flask? -

How to make a model not available on sertain dates and hours in Django?
So, I'm creating a room renting project. The renting is not for a whole day, it's only for 2 hours. I'm gonna have several renting companies each having several rooms for rent with diffrent capacity. So, my question is, if a room is rented on lets say 25/03/2022 20:00(so its gonna be unvailable until 22:00, and also unavailable 2 hours prior), I want the room to be still visible on the site, because someone maybe will want to rent it on diffrent day or the same day in diffrent hour. How to make this exact room unavailable only on this date and this hours? If I make is_available row in the model its gonna switch to False whenever someone rent it, but I want it to be available for all the other days and hours. Here are the models: class Owner(models.Model): name = models.CharField(max_length=100) address = models.TextField() phone = models.PositiveIntegerField() class Room(models.Model): number = models.CharField(max_length=100) owner = models.ForeignKey(Owner, on_delete=models.CASCADE) capacity = models.PositiveIntegerField() is_available = models.BooleanField(default=True) class reservation(models.Model): room_number = models.ForeignKey(Room) guest_name = models.CharField(max_length=200) guests = models.PositiveIntegerField() date_reserved = models.DateTimeField() -

I have two tables: class LocationType(models.Model): location_type = models.CharField(max_length=120, unique=True) comment = models.TextField(null=True, blank=True) def __str__(self): return self.location_type class Location(models.Model): location = models.CharField(max_length=100, unique=True) location_type = models.ForeignKey(LocationType, to_field="location_type", on_delete=models.CASCADE) comment = models.TextField(null=True, blank=True) def __str__(self): return self.location and I have created a location_type 'PLANT' and then referenced it while creating a location "GUJRAT". location_type1 = LocationType.objects.create(location_type="PLANT") location1 = Location.objects.create(location="GUJRAT", location_type=location_type1) Now after creating these two entries I want to change location_types value from "PLANT" to "FACTORIES". location_type1.location_type = "FACTORIES" location_type1.save() But I am getting below error: Traceback (most recent call last): File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/backends/utils.py", line 89, in _execute return self.cursor.execute(sql, params) File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/backends/sqlite3/base.py", line 477, in execute return Database.Cursor.execute(self, query, params) sqlite3.IntegrityError: FOREIGN KEY constraint failed The above exception was the direct cause of the following exception: Traceback (most recent call last): File "<console>", line 1, in <module> File "/home/jayantseth/Projects/ip_manager/IpManagerBackend/ipmanager/models.py", line 58, in save super(LocationType, self).save(*args, **kwargs) File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/models/base.py", line 806, in save self.save_base( File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/models/base.py", line 857, in save_base updated = self._save_table( File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/models/base.py", line 970, in _save_table updated = self._do_update( File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/models/base.py", line 1034, in _do_update return filtered._update(values) > 0 File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/models/query.py", line 885, in _update return query.get_compiler(self.db).execute_sql(CURSOR) File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/models/sql/compiler.py", line 1783, in execute_sql cursor = super().execute_sql(result_type) File "/home/jayantseth/Projects/ip_manager/venv/lib/python3.8/site-packages/django/db/models/sql/compiler.py", … -
Digital ocean droplet is only showing the default nginx page when connected with a namecheap domain
I'm using a Django Digital Ocean droplet to run a website where I recently tried connecting the IP address of the droplet to a namecheap domain name, but when I connected them it only showed this on the domain: Welcome to nginx! If you see this page, the nginx web server is successfully installed and working. Further configuration is required. For online documentation and support please refer to nginx.org. Commercial support is available at nginx.com. Thank you for using nginx. However, the website was working as intended on the IP address, can anyone tell me how to fix this? my abbreviated /etc/nginx/sites-available/default file server { listen 80 default_server; listen [::]:80 default_server; root /var/www/html; index index.html index.htm index.nginx-debian.html; server_name sanskarhandicrafts.com; location / { try_files $uri $uri/ =404; } } -
