I'm getting a bit crazy with this, I have a Event who has_many Attendants but I haven't been able to create dynamically inside the Event form, I have a partial with the form of Attendant, this works:
<%= form.fields_for :attendants do |form_attendant| %>
<%= render 'form_attendant', form_attendant: form_attendant %>
<% end %>
for 1 attendant, if I copy-paste that, it works for 2 and so on..
I want a button to do that for me, I've read and tried a loooot.
Option 1: I have tried in js to append that, with:
$("#attendants").append "<%= form.fie ... %>"
but It just print the text and won't render the partial, I have tried with escape_javascript too with no luck.
I'm now trying with:
<%= link_to "Agregar", new_attendant_path, remote: true %>
I have these in attendants/new.js.erb
$('#attendants').append("<%= escape_javascript ( render partial: 'form_attendants' ) %>");
Which actually works and render the partial but now I don't know how to send the local event form so I can make <%= form.fields_for :attendants do |form_attendant| %> ...
<%= form.fields_for :attendants do |form_attendant| %> ...
inside the partial,
Any help would be appreciated, I'm almost crying
Try nested_form_fields gem
= form_for @user do |f|
= f.nested_fields_for :videos do |ff|
= ff.remove_nested_fields_link
= ff.text_field :video_title
..
= f.add_nested_fields_link :videos
You can change the link text of remove_nested_fields_link and add_nested_fields_link , add classes/attributes, etc...
You can also customize the add/remove functionality, by overriding the
nested_form_fields.js.coffee into your rails JavaScript asset

<%= form_for @users do |f| %>
<%= f.fields_for :attendants do |form_attendant| %>
<%= render 'form_attendant', form_attendant: form_attendant %>
<% end %>
<%= f.add_nested_fields_link :attendants %>
<% end %>
partial _form_attendant.html.erb
<%= form_attendant.remove_nested_fields_link %>
<%= form_attendant.text_field :attd_date %>
<%= form_attendant.text_field :attd_time %>
