accepts_nested_attributes_for with has_many => :through Options

Question

I have two models, links and tags, associated through a third, link_tags. The following code is in my Link model.

Associations:

class Link < Acti         


        

Answer 1

In order for this to work, you need to pass in the right params hash:

params = {
  :link => {
    :tags_attributes => [
      {:tag_one_attr => ...}, {:tag_two_attr => ...}
    ],
    :link_attr => ...
  }
}

And your controller will look like:

def create
  @link = Link.create(params[:link]) # this will automatically build the rest for your
end
