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

Take a look at the line of your code

<% f.fields_for :tags_attributes do |tag_form| %>

You need to use just :tags instead of :tags_attributes. This will solve your issue

Make sure that You have build links and tags in your controller like

def new
  @link = @current_user.links.build
  @link.tags.build
end
