How to assign a default value to existing rows via Ash.postgres generated migration code
When a non-null column is added, is there a way to specify a default value to assign to the new column for existing records? I believe in Ecto, it's done something like this, but I'm curious if this can be done through Ash DSL.
add :new_field, :string, default: "default value"
add :new_field, :string, default: "default value"
If it makes a difference, the new column in my case is a source attribute for a relationship as in something like this. (So manually adding
default: "default value"
default: "default value"
actually causes a foreign_key_violation., which is a different issue on its own.)
belongs_to :theme, Items.Theme do api Items allow_nil? false destination_attribute :destination_new_field source_attribute :new_field attribute_type :integer end
