I knew what I was attempting wasnt a very good idea. I just wasnt sure
what to do inside the apply_filter method, for example, where I set the
dataset = dataset.where...
Inside the dataset_module, would that just be self = self.where(.....)?
# Apply criteria to dataset
filter_criteria.each do |attribute_name|
attribute_value = "#{params[attribute_name].gsub('*','%')}%"
dataset = dataset.where(Sequel.like(attribute_name.to_sym,
attribute_value))
end
