CanSearch
=========
Allows you create common named_scopes and chain them together with #search and
#search_for.
class Topic
belongs_to :forum
can_search do
scoped_by :forums
scoped_by :created, :scope => :date_range
end
# creates these two named scopes
# named_scope :by_forums, lambda { |f| {:conditions => {:forum_id => f}} }
# named_scope :created, lambda { |range| {:conditions => ...} }
end
Topic.search(:forum => 1) # Topic.by_forums(1)
Topic.search(:forums => [1,2]) # Topic.by_forums([1,2])
Topic.search(:created => (time1..time2)) # Topic.created(time1..time2)
Topic.search(:created => \
{:period => :daily, :start => Time.now}) # Topic.created(Time.now, Time.now + 1.day)
You can automatically paginate:
Topic.search :forum => 1, :page => params[:page]
You can also access the named_scope directly for custom #find or #calculate calls.
Topic.search_for(:forum => 1).sum(:hits)
Oh, and you can combine scopes:
Topic.search :forum => 1, :forums => [2, 3], :created => (time1..time2)
def can_search(&block)
self.search_scopes = CanSearch::SearchScopes.new(self, &block)
end
end
