Can not create multiple instance of Model using Factory Boy and Faker
I am trying to craate multiple instance of django model using django-factory-boy and faker. But the I need to create instance in bulk (not single).

Django website can't find template in new project website
Hey I'm looking for some advice on my situation as I can't seem to figure this out. I'm trying to build a website with Django following along with the tutorial they have on the webpage and I got stuck at a step where I want to add a view to my web page. My folder structure is so fart like this: PersonalWebsite | |--PersonalWebsite | |--urls.py |--dashboard | |--urls.py |=-views.py |--templates |--dashboard | |--index.html In my PersonalWebsite/urls.py I have : urlpatterns = [ path('admin/', admin.site.urls), path('', include('dashboard.urls')), path('resume/', include('resume.urls')), ] In my dashboard/urls.py I have: urlpatterns = [ path('', views.index, name='index'), ] And in my dashboard/view.py I have: def index(request): return render(request, 'dashboard/index.html') Then I have just some html in the index.html. I'm trying to basically have the dashboard app as the landing page of the website and from there I want to redirect to other apps like portofolio, articles, etc. My issue is that now I get a TemplateNotFound error when the website tries to access dashboard/index.html at localhost:8000/ address. I haven't changed anything in the settings files, it is a standard project. Any idea's why it can't find the index.html? -

How to access fields of a Model from ForeignKey for Validation?
Basic idea is Task --> Submission means each submission is associated with a Task with ForeignKey. This is my models.py file from django.db import models from django.core.validators import FileExtensionValidator class Task(models.Model): task = models.CharField(max_length=20) min_marks = models.IntegerField(default=0) max_marks = models.IntegerField(default=100) late_submission_date = models.DateField() late_submission_panalty = models.IntegerField() file_type = models.CharField(max_length=10) file_size = models.IntegerField("File Size in mb") created_date = models.DateTimeField(auto_now_add=True) def __str__(self): return f"Task:{self.task}" class Submission(models.Model): task = models.ForeignKey(Task, on_delete=models.CASCADE) team_id = models.IntegerField(unique=True) file = models.FileField("File", validators=[FileExtensionValidator(allowed_extensions=['zip'])]) # see here created_date = models.DateTimeField(auto_now_add=True) def __str__(self): return f"{self.team_id}@{self.created_date.strftime('%H:%M_%d_%m_%Y')}" Inside Submissions --> file i want to access file_type of task so i could validate submission file extension. I am really new to Django so any help would be nice. -
