问题 I have to convert my form to not using nested association. In other words, instead of <%= link_to_add_association f, :contacts, class: 'btn btn-primary', partial: 'projects/contact_fields', data: { association_insertion_node: '.contact_fields', association_insertion_method: :append } do %> <i class="fas fa-plus"></i> <% end %> <%= f.fields_for :contacts do |contact| %> <%= render 'projects/contact_fields', f: contact %> <% end %> I would like to be able to just pass in a string to be used as

问题 I am using materialize-sass gem on a form. Using autocomplete feature to get Vendor names. other fields on the form are item names and quantity which are a nested resource.

问题 I have a nested form where you can add new bracelets to your order. For each bracelet you can choose a color, and next to the select (dropdown) where you choose the color there is an image with the bracelet on that color. The problem is this: When I add a new nested-fields div (form for new bracelet), when I select a color in the dropdown the image next to it doesn't change.
