I'm following the tutorial on Getting Started with Rails — Ruby on Rails Guides, and got stuck on the very last section, "Building a Multi-Model Form". I'm trying to do two models in the same form, and I get the following error: undefined method `stringify_keys' for "tag1":String
Here is the partial view I am using:
<% form_for(@post) do |f| %> <%= f.error_messages %>
<p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> <p> <%= f.label :title %><br /> <%= f.text_field :title %> </p> <p> <%= f.label :content %><br /> <%= f.text_area :content %> </p>
<h2>Tags</h2> <% f.fields_for :tags_attributes do |tag_form| %> <p> <%= tag_form.label :name, 'Tag:' %> <%= tag_form.text_field :name %> </p> <% unless tag_form.object.nil? || tag_form.object.new_record? %> <p> <%= tag_form.label :_delete, 'Remove:' %> <%= tag_form.check_box :_delete %> </p> <% end %> <% end %>
<p> <%= f.submit 'Update' %> </p> <p> This was rendered by a partial view! </p> <% end %>
I'm still a beginner, so I hope this question isn't too dumb, but I'm scratching my head here - any help?
