MultiValueDictKeyError in Django admin
I think it is related to a Django 1.6 ticket
#ticket 13696 -- ensured inline pk field is rendered
You have to update the following admin templates:
- stacked.html
- tabular.html
Remove the single line:
{% if inline_admin_form.has_auto_field %}{{ inline_admin_form.pk_field.field }}{% endif %}
and add the lines:
{% if inline_admin_form.needs_explicit_pk_field %}
{{ inline_admin_form.pk_field.field }}
{% endif %}
If you are already on a newer version of django and still get this, make sure your non-AutoField PK has "editable=False" in the model definition.
For Django <= 1.7.3, also make sure, that the primary key field of your inline model is an AutoField:
wrong:
class Car(models.Model):
id = IntegerField(primary_key=True)
correct:
class Car(models.Model):
id = AutoField(primary_key=True)
