Values not being being reflected on page after validation error but model has the values

Rails
1

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? %>

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

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

test
// Prints the values correctly
<%= @payment.credit_card_number %>
<%= @payment.zip %>
<%= @payment.country %>

<%= f.label :credit_card_number %>
<%= f.text_field :credit_card_number , :autocomplete => "off" %>
<%= f.label :address_line_2 %>
<%= f.text_field :address_line_2 %>
<%= f.label :city %>
<%= f.text_field :city %>
<%= f.label :zip %>
<%= f.text_field :zip %>
<%= f.label :country %>
<%= f.text_field :country %>
<%= f.submit %>
<% 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}
  else
    format.html { render action: "new" }

  end
end

end

end

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?

<%= msg %>
<%= @payment.country %>

Controller code-> end format.html # index.html.erb format.html {redirect_to merchants_path} --

Thank you very much. I will read up on the difference. Sorry should have

It would’ve helped if you somehow bolded your answers. anyway, you
should
be able to do that by
changing this line

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

to

<%= form_for([@merchant, @payment]) do |f| %>

Good luck!

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


<%= f.text_field :zip %>
<% end %>
format.html # show.html.erb

respond_to do |format|

No worries. If you’re looking for the difference, @payment (as you
already
know) uses the same
record as the one you have in your controllers. If you use
@merchant.payments.build, you’re
creating a new payment record which does not contain the values
submitted
by the user :slight_smile:
