Child form is not saving

[sonq]

Hello there!

I know there are millions of issues like this and i know the issue is related to either a typo mistake or something about divs but i just cannot find it or i made another mistake and i cannot find it. So, please help me out.

Here is my model for parent form

class Diet < ApplicationRecord
  validates :die_desc, presence: true
  validates :die_type, presence: true
  has_many :dietlines, inverse_of: :diet
  accepts_nested_attributes_for :dietlines, reject_if: :all_blank, allow_destroy: true
  belongs_to :type
  belongs_to :user 
end

and this is model of the nested form

class Dietline < ActiveRecord::Base
  belongs_to :diet
  belongs_to :product

end

and here are my strong params

   def diet_params
        params.require(:diet).permit( :die_desc,
                                       :die_text,
                                       :type_id,
                                       :user_id,
                                       :die_type,
                                       dietlines_attributes: [:id,
                                                              :dil_desc,
                                                              :dil_meal,
                                                              :diet_id,
                                                              :product_id,
                                                              :dil_calories,
                                                              :dil_protein,
                                                              :dil_totalcarbs,
                                                              :dil_fat,
                                                              :dil_vita,
                                                              :dil_vitc,
                                                              :dil_calcium,
                                                              :dil_iron,
                                                              :dil_sodium,
                                                              :dil_potassium,
                                                              :dil_chol,
                                                              :dil_sugars,
                                                              :dil_fiber,
                                                              :_destroy])
    end

this is the _form view

<h2>Meals</h2>

         <br/>
         <%= f.fields_for :dietlines do |dietline| %>
           <%= render 'dietline_fields', f: dietline %>
         <% end %>

         <div>
            <br/>
            <%= link_to_add_association 'Add Line', f, :dietlines,class: "btn btn-outline-success" %>
            <%= f.submit  class: 'btn btn-outline-success' %>
         </div>
         <br/>

and finally this is the cocoon fields partial

<div class = "nested-fields">

 <div class ='container'>

  <div class="row">
      <div class="col col-lg-6">
         <%= f.autocomplete_field :dil_desc, autocomplete_product_pro_desc_dietlines_path, class: 'largeinput' %>
      </div>

        <div class="col col-lg-4">
           <%= f.select :dil_meal, ['Breakfast','Lunch', 'Dinner','Snack'], {prompt: "Select Meal"},{class: "specialdeviseinput"}%>
        </div>

        <div class="col col-lg-2">
          <div class ='linedelete'>
           <%= link_to_remove_association 'Delete', f, class: 'btn btn-outline-danger'  %>
           </div>
        </div>

      <br/>

  </div>

 </div>
</div>

any help will be appreciated!

Could you show us the part of the logfile, I would like to see what is posted to the controller and the possible error, if any?

nathanvda please find log, it shows no error or rollback but it does not attempt to save dietlines as i see.

Did you notice in the post-params it does not contain any child-data? This seems to suggest your html is incorrect, possibilities:

• you have form-data outside of your form (while the page may look ok, if the nested element is not inside the form, it will not be posted to the server)
• or repeating id's? (since an id can only occur once on a page, again your page may appear ok, but when the form is posted to the server, only the first occurence of an id is posted)

I am guessing in this case you will have to look at the first?

Dear Nathanvda,

thanks for your helps, i deleted all the divs and wrote them one by one. Now it works.

Thanks.
