How to implement a form with nested fields?
There are two related models class Skill(models.Model): """Information about an employee's skills.""" LEVELS = ( ('basic', 'Basic'), ('intermediate', 'Intermediate'), ('advanced', 'Advanced'), ('expert', 'Expert'), ) employee = models.ForeignKey( Employee, on_delete=models.CASCADE, related_name="employee_skills") technology = models.ForeignKey(Technology, on_delete=models.CASCADE) year = models.CharField('common year using amount ', max_length=4) last_year = models.CharField('Last year of technology using ', max_length=4) level = models.CharField("experience level", max_length=64, choices=LEVELS) class Technology(models.Model): """Technologies.""" name = models.CharField('technology name', max_length=32, unique=True) group = models.ForeignKey(Techgroup, on_delete=models.CASCADE, related_name="group") The point is that each technology has its own meaning for the level of ownership, years of experience and when it was last used. I made a form that allows to edit one technology at a time. forms.py class SkillEditForm(forms.ModelForm): YEAR_CHOICES = [(r, r) for r in range(1, 11)] LAST_YEAR_CHOICES = [(r, r) for r in range(1980, datetime.datetime.now().year + 1)] year = forms.CharField( widget=forms.Select(choices=YEAR_CHOICES), ) last_year = forms.CharField(widget=forms.Select(choices=LAST_YEAR_CHOICES)) class Meta: model = Skill fields = ['technology', 'level', 'last_year', 'year'] There are dozens of technologies in the database. Now I want to implement the ability to edit all the technologies in one window at once, so that the user does not have to press the button to add technology 10 times. Smth like: technology1 level last_year year ...... ...... technology_N … -

Defining a struct as a class attribute
I'm defining a class in a Django project and I want a class to have a specific structure. Versions used: Django2.2.3 python3.7 I thought about defining the struct as a class and then adding it as an attribute for the main class. But then I am afraid it will create a DB. This is what I tried: from django.db import models class Host(models.Model): id_host = models.CharField(max_length=20) [... more attributes here ...] class Apartment(models.Model): _id = models.CharField(max_length=20) host = Host() [... more attributes here ...] Any idea on how to do this correctly? -

In Django 1.6 - how to use a pre-existing database for unit tests? (--keepdb flag)
We are using Django 1.6.x for our codebase and there are no unit tests for the code. I want to begin to implement unit tests on the codebase and we have a Oracle database we can use for the task.
