Hi,
Please help!
Here is my model with a unique constrain.
class MaterialTransferRequestItem(models.Model):
transfer_request = models.ForeignKey(MaterialTransferRequest, on_delete=models.CASCADE)
material = models.ForeignKey(Material, on_delete=models.RESTRICT)
quantity = models.DecimalField(max_digits=12, decimal_places=4, default=1.0000)
from_location = models.ForeignKey(Location, on_delete=models.RESTRICT, null=True, blank=True,
related_name='material_transfer_request_from_location')
to_location = models.ForeignKey(Location, on_delete=models.RESTRICT,
related_name='material_transfer_request_to_location')
class Meta:
unique_together = ('transfer_request', 'material', 'from_location', 'to_location')
I have a template with MaterialTransferRequest model in the main form and the above model in the inline formset.
How can I show the unique constraint violation message in the inline formset?
What I’m looking for is similar to a normal form unique constrain violation message:
