Good afternoon!
I’m having a problem with storing models with nested Attributes.
In the app, we have Customer, which has 1.. n Contacts, which in turn has 1.. n Telephones.
I researched a lot before I put it here and decided to make it work only with Contact before. Well, at first the Customer is saved, but the Contact no. From what I read, there’s no need to repeat the .build model Child in function create, and the line "@Customer = Customer.new(customer_params)" create and save both. After searching hard for the error, I discovered that in the parameters that came from form, the hash required to register Contact came with the following structure ":contacts_attributes[:0[...(correct data)]]" that is, the data came encapsulated inside another hash. Because of this, my other solution did not work (Put the Contacts.build(customer_params[:contacts_attributes]) the more). I imagine this is in case I add more than one Contact at a time.
I couldn’t find a clear explanation of how this works, but I’ve arrived at the following codes :
Customer.Rb
class Customer < ActiveRecord::Base
...
has_many :contacts
accepts_nested_attributes_for :contacts, reject_if: lambda {|attributes| attributes['kind'].blank?}
...
def change_by(user_id)
update_attributes(changed_by: user_id, deleted_at: Time.now, updated_at: Time.now)
end
def delete(user_id)
update_attributes(status: false, changed_by: user_id, deleted_at: Time.now, updated_at: Time.now)
end
private
...
end
customers_controller.Rb
class CustomersController < ApplicationController
def new
@customer = Customer.new
@customer.contacts.new
end
def create
user_id = session[:user_id]
@customer = Customer.new(customer_params)
if @customer.save
@customer.change_by(user_id)
flash[:success] = "Cliente cadastrado com sucesso!"
redirect_to customers_url
else
render 'new'
end
end
private
def customer_params
params.require(:customer).permit(:razao_social, :nome, :CPF_CNPJ,
:adress_id, :email_nota, :transporter_id, :observacao,
contacts_attributes: [:nome, :setor, :email])
end
Entry form
<div class="row">
<div class="col-md-6 col-md-offset-3">
<%= form_for @customer do |f| %>
<%= f.label "Dados Básicos" %>
<div class="well">
<%= f.label :razao_social, "Razão Social" %>
<%= f.text_field :razao_social %>
<%= f.label :nome, "Nome" %>
<%= f.text_field :nome %>
<%= f.label :CPF_CNPJ, "CPF/CNPJ" %>
<%= f.text_field :CPF_CNPJ %>
<%= f.label :email_nota, "Email para nota" %>
<%= f.email_field :email_nota %>
<%= f.label :observacao, "Observações" %>
<%= f.text_area :observacao %>
</div>
<%= f.fields_for :contacts do |k| %>
<%= k.label "Contato" %>
<div class="well">
<%= k.label :nome, "Nome" %>
<%= k.text_field :nome %>
<%= k.label :setor, "Setor" %>
<%= k.text_field :setor %>
<%= k.label :email, "Email" %>
<%= k.email_field :email %>
</div>
<% end %>
<%= f.submit "Cadastrar Cliente", class: "btn btn-primary" %>
<% end %>
</div>
