This is for a glossary that I setup ...
class Glossary
def self.find_glossaries(options = {})
if options[:category].blank?
paginate :per_page => options[:per_page], :page => options
[:page],
:conditions => ["term LIKE ?", options[:letter]+"%"], :order
=> "term"
else
end
end
end
Then in the controller
@letter = params[:letter].blank? ?
@category.glossaries.collect.first.term.first.upcase : params[:letter]
@glossaries = @category.glossaries.find_glossaries(:letter =>
@letter, :page => params[:page])
There is more to this but the the important one is the model
find_glossaries
And then this view helper:
def letter_options(category=nil)
if category.nil?
@letter_options_list = Glossary.all.collect!{|c|
c.term.first.upcase }.uniq.sort!
else
@letter_options_list = category.glossaries.collect!{|c|
c.term.first.upcase }.uniq.sort!
end
end
I hope this get you going...
