pass array hidden field in nested model rails

Question

I have following code in my view:

    <% @m1.map(&:id).each do |id|%>

    <%= b.fields_for :modul1hours do |f| %>

    <%= f.hidden_field :mo         


        

Answer 1

In this line:

<%= f.hidden_field :modul1_id, id %>

You are saying that you want the hidden field binded with modul1hour modul1_id method and options being id. Second parameter for FormBuilder hidden_field is expected to be a hash (which is then merged against default options). To do what you want do:

<%= f.hidden_field :modul1_id, value: id %>
