These are my simple models.
class Customer(models.Model):
name = models.CharField(max_length=50)
email = models.EmailField(null=True, blank=True, unique=True)
phone = models.CharField(max_length=30, null=True, blank=True)
def __str__(self):
return self.name
class Box(models.Model):
customer = models.ForeignKey(Customer, on_delete=models.CASCADE, related_name='box')
box_status = models.CharField(max_length=20)
these are my model admin classes.
from django.contrib import admin
from .models import Customer, Box
@admin.register(Customer)
class CustomerAdmin(admin.ModelAdmin):
list_display = ['name', 'email', 'phone', 'box_status']
list_editable = ['phone', 'box_status']
def box_status(self, obj):
det = list(obj.box.values_list('box_status', flat=True))
return det
@admin.register(Box)
class BoxAdmin(admin.ModelAdmin):
pass
Now box_status from related model can work list_display but not working in list_editable. the error is
<class 'django.forms.widgets.admin_class'>: (admin.E121) The value of 'list_editable[1]' refers to 'box_status', which is not an attribute of 'newapp.Customer'.
