Module Sequel::Model::DatasetMethods
In: lib/sequel/model/base.rb

Dataset methods are methods that the model class extends its dataset with in the call to set_dataset.

Methods

destroy   to_hash  

Attributes

model  [RW]  The model class associated with this dataset

Public Instance methods

Destroy each row in the dataset by instantiating it and then calling destroy on the resulting model object. This isn‘t as fast as deleting the dataset, which does a single SQL call, but this runs any destroy hooks on each object in the dataset.

     # File lib/sequel/model/base.rb, line 920
920:       def destroy
921:         @db.transaction{all{|r| r.destroy}.length}
922:       end

This allows you to call to_hash without any arguments, which will result in a hash with the primary key value being the key and the model object being the value.

930:         else
931:           raise(Sequel::Error, "No primary key for model") unless model and pk = model.primary_key
932:           super(pk, value_column) 
933:         end
934:       end
