Hi there, I have a similar problem. I'm building a CMS and we have a
tree model called component_instances. This model has polymorphic
associations with many other models (e.g. Links, Folders, Pages etc...)
I want the user to be able to search for an instance using data stored
in the associated models. To start with in the backend interface, I only
want them to be able to search for items by name, so I came up with
this:
class ComponentInstance < ActiveRecord::Base
has_many :permissions
has_many :groups, :through => :permissions
belongs_to :component #will be in different database ??
acts_as_tree :order => 'position'
acts_as_list :scope => 'parent_id'
belongs_to :instance, :polymorphic => true
acts_as_ferret(
:fields => :instance_name
)
def instance_name
instance.name
end
end
Now that looks like it should work. But when I search for an item by
name (knowing that it exists), nothing shows. I know the search itself
works because becure I added the :fields condition, it would pick up and
return results for the word "folder" as it was used to define the
polymorphic associations on the instances table.
So firstly your help with that problem would be most appreciated. Then
we make things trickier by adding the fact that I'd like the end users
on the front end to be able to search the site not just using the name
field, but basically anything in any of the instance tables.
As a laughing point, when I wrote the original application in PHP using
Mysql fulltext search, the query for the frontend search was 2 pages
long! :)
Looking forward to your great ideas! :)
