plugin :auto_validations

[PetrKaleta]

Hello,
I am following on discussion I've started here https://groups.google.com/g/sequel-talk/c/DH4WXCAWdIg/m/Y2Du3gPwAwAJ so how to disable unique auto validations on all models.

So far I was using this code

Sequel::Model.plugin :subclasses do |sub_class|
  sub_class.skip_auto_validations(:unique)
end

But currently I've found, that on some models it doesn't work. And I have no idea why... Is there something wrong on this approach? Also there's one strange behavior on subclasses plugin, when using block, some sub_classes are anonymous... Where are they coming from?

You can probably override the related method: def (Sequel::Model).auto_validate_unique_columns; []; end.

As to why your approach doesn't work, I'm not sure. Maybe you are running it before creating the related subclasses? Hard to guess why without a self contained example.

As to why some subclasses are anonymous, I'm guessing you are doing something like: class Foo < Sequel::Model(:table_name), and Sequel::Model(:table_name) creates an anonymous subclass, which you then create a subclass of.

Ah, okey, I understand why there are those anonymous classes now. I did some debugging and found this strange behavior in this code:

Sequel::Model.plugin :subclasses do |sub_class|
  sub_class.skip_auto_validations(:unique)
end

So let's say I have model Foo. So in block above sub_class == Foo and sub_class.auto_validate_unique_columns is nonempty. After sub_class.skip_auto_validations(:unique) is applied then sub_class.auto_validate_unique_columns is [], which is expected behavior. But in code after this block, it is again nonempty. Which is super strange.

I've checked auto_validations plugin source code and I think it will be related to this line Plugins.after_set_dataset(self, :setup_auto_validations). It seems that for some reason, dataset for my Foo model was reseted... Maybe it has something to do with those anonymous classes, as I am using this approach class Foo < Sequel::Model(:table_name) or maybe some plugins?

This is how my models.rb looks like (there are no additional plugins on Foo model):

require_relative 'db'

Sequel::Model.db = DB[:default]
Sequel::Model.plugin :string_stripper
Sequel::Model.plugin :boolean_readers
Sequel::Model.plugin :timestamps, update_on_create: true
Sequel::Model.plugin :auto_validations
Sequel::Model.plugin :tactical_eager_loading
Sequel::Model.plugin :subclasses do |sub_class|
  sub_class.skip_auto_validations(:unique)
end
Sequel::Model.plugin :empty_failure_backtraces if ENV['RACK_ENV'] == 'production'

Dir[File.join(__dir__, 'models/**/*.rb')].sort.each { |f| require f }

Sequel::Model.freeze_descendents unless ENV['RACK_ENV'] == 'development' || ENV['RACK_ENV'] == 'test'

Try moving the plugin :subclasses call after the Dir[File.join(__dir__, 'models/**/*.rb')].sort.each { |f| require f } line. You want to make sure all subclasses are already loaded before skipping the auto validations for them.
