= New Features
* A subset_conditions plugin has been added, which adds a method
for each subset that returns the filter conditions for the
subset. This makes it easier to reuse the subset conditions:
class Foo < Sequel::Model
plugin :subset_conditions
subset :active, :active=>true
end
Foo.exclude(Foo.active_conditions)
Foo.where(:a=>1).or(Foo.active_conditions)
* A boolean_subsets plugin has been added, which adds a subset for each
boolean column:
# Assume boolean column :active
Foo.plugin :boolean_subsets
Foo.active
# SELECT * FROM foos WHERE (active IS TRUE)
You can provide a block to the plugin to change the arguments passed
to subset:
Foo.plugin :boolean_subsets do |column|
[:"where_#{column}", column]
end
Foo.where_active
# SELECT * FROM foos WHERE active
As with similar plugins, you can add the boolean_subsets plugin to
Sequel::Model itself, and all subclasses created afterward will have
the boolean subset methods automatically created.
= Other Improvements
* If Model#refresh can't find the related row, Sequel now raises a
Sequel::NoExistingObject exception instead of a generic
Sequel::Error exception.
* In the csv_serializer plugin, when calling #to_csv on a model class
or dataset, instead of using #[] to access data, #send is used to
call methods. This is more similar to other plugins as well as
Model#to_csv.
* The list plugin now works better with the auto_validations plugin,
or any other time there is a validation on the position column.
= Backwards Compatibility
* The change to the csv_serializer plugin can change results if you
are overriding any of the column accessor methods. It can also
break existing code if one of the columns being used isn't defined
as a method or the method requires more than one argument.
