I'm working on a Rails 5.2 application requiring the storing of a Quote, and one QuoteLineItem to go wwith it (Quote has_one :quote_line_item, QuoteLineItem belongs_to :quote). I've set it all up according to documentation, however when submitting the quotes#edit for (which contains fields_for @quote.quote_line_item...), the values for the Quote record are updated in the database, however values for the QuoteLineItem are not. No error is thrown on submission, and no "Unpermitted params..." message in server logs.

Quote Model

class Quote < ApplicationRecord

  has_one :quote_line_item, inverse_of: :quote, dependent: :destroy

  accepts_nested_attributes_for :quote_line_item, update_only: true

end

QuoteLineItem Model

class QuoteLineItem < ApplicationRecord

  belongs_to :quote, inverse_of: :quote_line_item, touch: true

end

Quotes Controller

class QuotesController < ApplicationController

  def update

    @quote = Quote.find(params[:id])



    if @quote.update(quote_params)

      flash[:success] = "Quote was successfully updated."

      redirect_to @quote

    else

      flash[:error] = "Quote was not updated. Please try again."

      render :edit

    end

  end



  private

    def quote_params

      params.require(:quote).permit(:issued_at, quote_line_item_attributes: [ :kind, :description, :price ])

    end

end

Quotes Edit View

<%= form_for @quote do |quote_form| %>

  <% if @quote.errors.any? %>

    <div id="error_explanation">

      <h2><%= pluralize(@quote.errors.count, "error") %> prohibited this quote from being saved:</h2>



      <ul>

        <% @quote.errors.full_messages.each do |message| %>

          <li><%= message %></li>

        <% end %>

      </ul>

    </div>

  <% end %>



  <%= quote_form.label :issued_at %>

  <%= quote_form.datetime_field :issued_at %>



  <%= fields_for :quote_line_item, @quote.quote_line_item do |quote_line_item_fields| %>

    <%= quote_line_item_fields.label :description %><br>

    <%= quote_line_item_fields.text_field :description %>



    <%= quote_line_item_fields.label :price %>

    <%= quote_line_item_fields.number_field :price, step: :any %>

  <% end %>

<% end %>

Is there a reason this shouldn't be working?

Thanks.

Try referencing quote_form before your fields_for:

<%= form_for @quote do |quote_form| %>



  ...



  <%= quote_form.fields_for :quote_line_item do |quote_line_item_fields| %>

  #   ^ <- Add here



    ...



  <% end %>

<% end %>

After updating this, check that the parameters being passed to quotes#edit are nested:

i.e: "quote"=>{"issued_at"=>"12/11/2018 11:05 AM", "quote_line_item"=>{"description"=>"Line item description goes here...", "price"=>"200.00"}, "id"=>"63"}
