How to show name instad of id in django ForeignKey? - django

Question

I have a model with a ForeignKey to itself.
models.py
class Person(models.Model):
name = models.CharField(max_length=20)
important_name = models.ForeignKey('Person', on_delete=models.SET_NULL, blank=True, null=True, related_name='first', verbose_name='Very Important Name')
def __str__(self):
return self.name
def get_fields(self):
return [(field.verbose_name, field.value_from_object(self)) for field in self.__class__._meta.fields]
And when i want to show my data with DetailView CBV in view it show id instead of name.
views.py
class DetailPerson(DetailView):
model = Person
template_name = 'panel/detail_person.html'
detail_person.html
<table class="table">
{% for label, value in object.get_fields %}
<tr>
<td>{{ label }}</td>
<td>{{ value }}</td>
</tr>
{% endfor %}
</table>
How can i show name instead of id?

Answer 1

Here we can use getattr instead of value_from_object, which will return us the related instance of Person instead of an ID.
def get_fields(self):
return [(field.verbose_name, getattr(self, field.name)) for field in self.__class__._meta.fields]
example:
from base.models import Person
a = Person.objects.first()
a.get_fields()
Returns
[('ID', 1), ('name', 'Joe'), ('Very Important Name', <Person: Bob>)]
Now, we may access all of Bob's attributes in the template as well, if the need arose.
