Is there a way change the dataset module as you are joining multiple
associations and tables?
For example:
class User < Sequel::Model
dataset_module do
def with_min_age(min_age, u = Sequel[model.table_name])
condition = Sequel.lit("? <= current_date - (? || '
years')::interval", u[:birth_date], min_age)
condition = Sequel.|({min_age => nil}, condition) if
min_age.is_a?(Sequel::SQL::Expression)
where(condition)
end
end
end
So I can use this as users_dataset.with_min_age(4).
But I'd like to be able to also do:
books_dataset.association_join(:user).with_min_age(Sequel[:books][:min_age_required],
Sequel[:user])
To be able to reuse the methods.
Is something like this possible?
