bug: cannot update attributes with name "updated_at"

[fatih-acar]

Component

API Server / GraphQL Infrahub 0.14.2

Current Behavior

When using a schema defining nodes that have an attribute named updated_at, it is not possible to change the value of this attribute and it is always blank/null.

Expected Behavior

updated_at attributes should be editable as expected

Steps to Reproduce

Load the following schema:

---
version: "1.0"
nodes:
  - name: Country
    namespace: Otterbox
    label: Country
    attributes:
      - name: name
        kind: Text
        unique: true
        optional: false
      - name: created_at
        kind: DateTime
        optional: false
      - name: updated_at
        kind: DateTime
        optional: false

Create a new Country node with a name, created_at and updated_at set. You will see that created_at is correctly set but updated_at is not.

Added to 0.16.1 provided that this is a quick fix. I think it should be enough with this change:

             self._updated_at = Timestamp(updated_at)

If this causes other problems we could perhaps move this to another milestone.

The problem is that we use an "updated_at" argument within the Node class to set the old metadata field _updated_at. The end goal would be to have correct metadata properties for each node where you as a user would be able to see when a node was created and when it was last updated. Even with that in place we shouldn't limit users from using the attribute name updated_at.
