I’m trying to perfom validation on a liveview field but can’t wrap my mind around what the problem is
Ecto.Changeset.validate_number(:number_field, greater_than: 0)
the changeset does not return any errors when the input value is 0. It does return an error when the value is -1 to -n. I have alternatively tried using less than, here is a snippet of the same
Ecto.Changeset.validate_number(:number_field, less_than: 0)
Is there an alternative way to validate the number field to make sure it is never going to be zero.

Are you sure the value is changed to
0– as opposed to already being zero/defaulting to zero or not being set?For not being set you’d need to add
validate_requiredas well and for the already 0 or default to 0 case you need to either useforce_changeon cast or make sure the value is not already 0 before adding the changes.
