getattr on related not possible?

[sebasti...@gmail.com]

Hello,

i have following:

models.py:

from django.db import models

class Tabs(models.Model):

    id = models.AutoField(primary_key=True)

    def __str__(self):

        return self.name

class Box(models.Model):

    id = models.AutoField(primary_key=True)

    tabslink = models.ForeignKey(Tabs, on_delete=models.CASCADE, null=False,blank=False)

    def __init__(self, *args, **kwargs):

        super().__init__(*args, **kwargs)

        print([field.name for field in self._meta.get_fields()])

        for field in [field.name for field in self._meta.get_fields()]:

            getattr(self, field)

views.py:

from django.views.generic.edit import (

    CreateView,

)

from django.urls import reverse, reverse_lazy

from django import forms

class Boxform(forms.ModelForm):

    class Meta:

        model = Box

        fields = ['tabslink']

class test(CreateView):

    model = Box

    template_name = 'test.html'

    form_class = Boxform

    success_url = reverse_lazy('Boxlistview')

Now i get a Exception:

Exception Value: Box has no tabslink.

/home/sebastian/PycharmProjects/test3/test4/models.py, line 22, in __init__

            getattr(self, field) …

▶ Local vars

/home/sebastian/.local/lib/python3.8/site-packages/django/db/models/fields/related_descriptors.py, line 197, in __get__

            raise self.RelatedObjectDoesNotExist( …

▶ Local vars

This happens only on fields that have a  models.ForeignKey entry...

Please help me that i can also get related with getattr.

Regards
