cocoon: undefined method `label' for false:FalseClass

Hello, something is wrong on my side… I used cocoon for other projects and has no such problem: undefined method 'label' for false:FalseClass

I am using regular rails form with fields_for:

<%= form_for [:admin, @phone_num], html: { class: 'form-horizontal' } do |f| %>
<%= f.fields_for :email_addresses do |ea| %>
          <%= render 'email_address_fields', ea: ea %>
          <div class='col-md-12 links'>
            <%= link_to_add_association 'Add Email Address', f, :email_addresses %>
          </div>
      <% end %>
<% end %>

And the partial:
<%= ea.label :address, class: 'control-label col-md-2' %>
<%= ea.email_field :address, class: 'form-control required' %>
<%= link_to_remove_association 'Remove address', ea %>

the error occur on first line of partial… 😕 What is wrong here ?

Rails 5.1.2 cocoon (1.2.11)

Hi @nathanvda , thanks for stepping in ! You right, I moved it outside of loop of fields_for but still the issue.

But once i set form_name: 'ea' its worked 😃

I totally missed this… and the form_name.

Thank you @Mirv and @nathanvda for your help !

Hi @alexey, so looking at the top of the question, everything is looking pretty good at first.

Except you are using a different form_name for your partial, and I am guessing this is causing the error. Secondly you write your link_to_add_association inside the fields_for loop which will show a link for each nested item, and not show a link if there are no nested items, so to solve those two problems you could write:

<%= form_for [:admin, @phone_num], html: { class: 'form-horizontal' } do |f| %>
    <%= f.fields_for :email_addresses do |ea| %>
        <%= render 'email_address_fields', ea: ea %>
    <% end %>
    <div class='col-md-12 links'>
        <%= link_to_add_association 'Add Email Address', f, :email_addresses, form_name: 'ea' %>
    </div>
<% end %>
