I am displaying a bunch of records from a table called "assets". Next to each record i have a checkbox.

Im struggling with the logic to save to another table. I know how to do it if the asset_id is already in the

Hi, I''ve search for documentations on queries with Arel 2 but there is pretty nothing and all I''ve found is for Arel 1 so I''ve run into NoMethodError: undefined method `[]'' for #<Arel::SelectManager:0x00000003f1b820> errors with join syntax.

I have a model Asset which has_and_belongs_to_many :tags. Tag has only one field, name. There is a table assets_tags which only has an asset_id and a tag_id. I can add a tag to one asset. If I try to add the same tag to another asset though (asset.tags << tag) I get this error: Mysql::Error: #23000Duplicate entry ''4'' for key 1: INSERT INTO assets_tags (`tag_id`, `id`,

hey all In my schema, Lesson is many to many with Asset (through join table ''elements''), which are also many to many with Resource (through join table ''items''). This is all done with totally standard "has_many :through" - Lesson has_many :elements, :dependent => :destroy, :order => :position has_many :assets, :through => :elements,

describe Asset, " when destroyed" do fixtures :assets, :videos, :sites, :publish_settings before(:each) do @asset = assets(:test_asset) @mock_hook = mock("hook") @asset.video.stub!(:hook).and_return @mock_hook # error occurs here end it "should call the delete hook" do @mock_hook.should_receive(:update).with("test_video",

A model has 2 columns in its table asset_type_id asset_id the asset_type_id links directly to the table asset_types via a belongs_to asset_types contains a single column ''name'' method_missing in the model says when you call a method matching /^asset.*/ call the corresponding method substituting ''asset'' for the contents of asset_type.name (ie. the name in

I am trying to create a model that allows only unique assets to be added to a category. However, they could be added again to a different category. Finally, an asset can be shared across many categories. So my question is how do you check the uniqueness across a join table? This does not compile.... has_and_belongs_to_many :categories, :foreign_key => ''asset_id''

Every time I use an asset tag helper, there is a parameter appended to the end of my file name. e.g. <input src="/images/search.gif?1213816620" type="image" /> From what I am reading, this appears to be a timestamp for caching purposes. It works in most cases, but I want to use image_path to embed a flash file. .swf file in public/images/flash e.g.

Dear All, I would like to know if it is possible to obtain the optimal asset allocation with the fPortfolio library (or others), but setting at the beginning a desired level of Target Risk.

If I have a class, Asset, which has and belongs to many associated Asset objects, how do I do this? has_and_belongs_to_many :associated_assets, :class => "Asset", :foreign_key => ?????, :association_foreign_key => ?????
