I have made myself a small activity model like this =>
# == Schema Information # Schema version: 20110519174324 # # Table name: activities # # id :integer not null, primary key # account_id :integer # action :string(255) # item_id :integer # item_type :string(255) # created_at :datetime # updated_at :datetime
belongs_to :account belongs_to :item, :polymorphic => true
from this i can get a nice timeline/actions/userfeed or what we want to call it from =>
def self.get_items(account) item_list = items = where(:account_id => account.id).order("created_at DESC").limit(30) items.each do |i| item_list << i.item_type.constantize.find(i.item_id)
Quick note here - this can be more effectively replaced by:
item_list << i.item
since that's the whole point of the :polymorphic => true declaration...
it works like a charm for objects not refering to others - like if a user uploads a new image i can get the image nice and tidy. But for comments => then i want to get the original post info, can i get that in get_items directly ? Someone got tips for me ?
I suspect you'll likely be doing that farther up in the code, where the results of get_items are used. For instance, one might do something like this:
<%= Activity.get_items(some_account).do |item| %> <%= render :partial => "#{item.class.name.underscore}", :locals => { :item => item } %> <% end -%>
then the individual item partials can deal with calling more methods on the object.

Thanks Matt,
Now i just have to figure out how to do the "calling more methods on the object". I havent seen or used "#{item.class.name.underscore}" so i guess the key are in that - hopefully i dig into this.

Got it working, you are my hero!
