HasFilter allows you to find a model with a specific set of conditions, eliminating complex sets of filter conditions in filter forms.
Add this line to your Gemfile:
gem 'has_filter'In Rails 2.3, you also have to add it to your envoriment.rb:
config.gem 'has_filter'$ bundle installclass Post < ActiveRecord::Base
has_filter
endAnd now you can use:
Post.filter(:active => true) #=> All active posts
Post.filter(:active => [true, false]) #=> All posts active or not
Post.filter(:title => "Something") #=> All that match with title Something (title like %Something%)You can also specify which attributes should be filtered.
class Post < ActiveRecord::Base
has_filter :title #=> It will only filter by title conditions
endPost.filter(:active => true) #=> No filtering
Post.filter(:title => "Something", :active => true) #=> All that match with title Something (title like %Something%) ignoring active condition
