No error . Validation error is populated but form does not retain values. Payment object has the values though.

This is still confusing.  What exactly do you want to do?

• Show the validation errors on the form page?
• Fix the payment process because you don't know what validations are failing?
• retain the values passed by the user when validations fail?

I have a relationship where a merchant can have multiple payments. I am posting payments to a merchant and there is a validation error. Payment object does have the values retained. Can some one help me fix the issue?

View Code->

<%= @merchant.name %>

<%= form_for([@merchant, @merchant.payments.build]) do |f| %>

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

<div id="error_explanation">

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

<ul>

<% @payment.errors.full_messages.each do |msg| %>

<li>

<%= msg %>

</li>

<% end %>

</ul>

</div>

<% end %>

test

// Prints the values correctly

<%= @payment.credit_card_number %> 

<%= @payment.zip %>

<%= @payment.country %>

<div class="field">

<%= f.label :credit_card_number   %>

<br />

<%= f.text_field :credit_card_number , :autocomplete => "off" %>

</div>

<div class="field">

<%= f.label :address_line_2 %>

<br />

<%= f.text_field :address_line_2 %>

</div>

<div class="field">

<%= f.label :city %>

<br />

<%= f.text_field :city %>

</div>

<div class="field">

<%= f.label :zip %>

<br />

<%= f.text_field :zip %>

</div>

<div class="field">

<%= f.label :country %>

<br />

<%= f.text_field :country %>

</div>

<div class="actions">

<%= f.submit %>

</div>

<% end %>

Controller code->

class PaymentsController < ApplicationController

  # GET /merchants/1

  # GET /merchants/1.json

  def new

    @payment = Payment.new

    @merchant = Merchant.find(params[:merchant_id])

    respond_to do |format|

      format.html # show.html.erb

    end

  end

  def index

    if params[:merchant_id]

      @payments =  Merchant.find(params[:merchant_id]).payments

    else

      @payments = Payment.all

    end

    respond_to do |format|

      format.html # index.html.erb

      format.json { render json: @merchants }

    end

  end

  def create

    @merchant = Merchant.find(params[:merchant_id])

    @payment = @merchant.payments.create(params[:payment])

    respond_to do |format|

      if @merchant.save

        format.html {redirect_to merchants_path}
