need help on editing nested-forms

[Ezekiah]

Hello,

My aim is to be able to call existing nested objects in my database and edit them.
To do so I created a template which display the form objects according to an xml schema, each class has it's own form.

Example of form :

builder = Nokogiri::XML::Builder.new do |t|
t.agent{      
          t.association(:type=>'association', :name=>'orgunits',  :display=>'public', :class_name=>'Orgunit')
          t.association(:type=>'association', :name=>'persons',  :display=>'public', :class_name=>'Person')
          t.rec_class(:type=>'hidden', :value=>'Agent')
          t.rec_id(:type=>'hidden', :value=>'', :display=>'public')

       }

I can display existing objects with the link_to_add like this :

- link = link_to_add_association(' ', f, node_name.to_sym, :partial=>'/studies/display_fields', 
                  :render_options => {:locals => {:fedora_object=>data, :rec_type=>node_name, :edit=>true,:xml=>Object.const_get(class_name.capitalize).xml_form.to_xml,  :xpath=>'/'+class_name.to_s.singularize.downcase+'/*'}, },:data => {"association-insertion-method" => "before" },)
                  - link = Nokogiri::HTML(link)

However when I open my edit popup the link_to add buttons generate wrong names.

It should output :
study[authors_attributes][1395055572220][orgunits_attributes][1395055573891][name]

But it displays :
study[new_authors][orgunits_attributes][1395055573891][name]

Could you help me, I don't think you have time to explore my code but do you know a good way to edit nested forms ?

I quickly checked your link, and you have an awful lot of code in a partial. Commonly it is not good practice to be having that much code in a view.

Also it is not entirely clear what you are doing exactly.

So, this gem is intended to be used with the form_for and fields_for helpers (and their derivatives in simple_form or formtastic). So not sure how you build your form, with XMLBuilder --> are you building your html that way?

It is a technique I do not know and I am not sure cocoon supports this at all.

Anyway: a quick look revealed you use simple_form_for, but there is no simple_fields_for call anywhere, this explains why the attributes are built incorrectly. But frankly I do not understand your code well enough to give you a good solution at this moment.
You seem to be using the same view to be iterating over all elements, and to render a single element.

Yes this is quiet hard to understand

Ok, but you are most definitely missing the simple_fields_for, so you should try to fix that. And if you would be able to make it a little more simpler, your code, it will become easier for you and me to to understand and help you. But of course, it could be that it needs to be this complicated.

Good luck 👍

I am not sure if I can do a lot to help you now?
