#30502 closed Bug (invalid)

Admin interface hangs on models with "parentNode" field .

Description

if you have a relation named "parentNode", the django admin page gets stuck/unresponsive (eternal loop in js code?) when adding/editing a row with the problematic relation.

Example model that triggers the bug:

class Node(models.Model):

    name = models.CharField(max_length=255)
    # "parentNode" as the foreign key name causes problems with Django admin js code =(
    parentNode = models.ForeignKey('self', blank=True, null=True, on_delete=models.CASCADE)

Thanks for the report. I reproduced this issue but it is not related with any of Django's JS. jQuery hangs even if CharField is named parentNode. You can try to look for a help on jQuery support channels. Personally, I would try to avoid using DOM properties as a field names.
