12 years ago More on the above:
>>> e = ElementText.objects.get(pk=1)
>>> e._meta.pk
<django.db.models.fields.AutoField object at 0x035F4D70>
>>> e._meta.pk.column`` 'id' >>> >>> e.element_text = 'test' >>> e.save()`
Traceback (most recent call last):
...
(same traceback as above)
When saving the model, it saves the primary key (in this case a self identified autofield called id), it also saves the reference to a foreign key, but it does not save the text nor does it save the search_index column.
Here is the traceback:
