I need to create two objects in same form (rails) - ruby-on-rails

Question

so please imagine a form for a car reservation, the form contains both some client information(name, age, city..) and also the reservation informations(start_date, end_date...).
So obviously, i need to create in the same form a client first, based on the informations and then the reservation which is related to the created client:
class Client < ActiveRecord::Base
has_many :reservations
end
.
class Reservation < ActiveRecord::Base
belongs_to :client
belongs_to :voiture
end
Here is what i did until now(bad way).
The reservation informations start with f.text_field, and the client informations only with text_field(very bad way yes :( )
<%= form_for([#voiture, #voiture.reservations.new]) do |f| %>
<div class="row">
<div class="col-md-12 price_tag">
<span><%= #voiture.price %>Dhs</span>
<span class="pull-right">Par jour</span>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label>Nom</label>
<%= text_field :nom, readonly: 'true', placeholder: 'Nom', class: 'form-control' %>
</div>
<div class="col-md-6">
<label>Prenom</label>
<%= text_field :prenom, readonly: 'true', placeholder: 'Prenom', class: 'form-control', disabled: 'true' %>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label>CIN</label>
<%= text_field :cin, readonly: 'true', placeholder: 'CIN', class: 'form-control' %>
</div>
<div class="col-md-6">
<label>Age</label>
<%= text_field :age, readonly: 'true', placeholder: 'Age', class: 'form-control', disabled: 'true' %>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label>Ville</label>
<%= text_field :ville, readonly: 'true', placeholder: 'Ville', class: 'form-control' %>
</div>
<div class="col-md-6">
<label>Télephone</label>
<%= text_field :telephone, readonly: 'true', placeholder: 'Telephone', class: 'form-control', disabled: 'true' %>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label>Email</label>
<%= text_field :email, readonly: 'true', placeholder: 'Email', class: 'form-control' %>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label>Check In</label>
<%= f.text_field :start_date, readonly: 'true', placeholder: 'Start Date', class: 'form-control' %>
</div>
<div class="col-md-6">
<label>Check Out</label>
<%= f.text_field :end_date, readonly: 'true', placeholder: 'End Date', class: 'form-control', disabled: 'true' %>
</div>
</div>
<%= f.hidden_field :voiture_id, value: #voiture.id %>
<%= f.hidden_field :prix, value: #voiture.prix %>
<%= f.hidden_field :total, id: 'reservation_total' %>
<%= f.submit "Book Now", id:"btn_book", class: "btn btn-primary wide", disabled: 'true' %>
Controller :
class ReservationsController < ApplicationController
before_action :authenticate_user!
def create
#client = Client.create(client_params)
#reservation = #client.reservations.create(reservation_params)
redirect_to #reservation.voiture, notice: "Votre reservation a bien ete cree"
end
def reservation_params
params.require(:reservation).permit(:start_date, :end_date, :prix, :total, :voiture_id)
end
def client_params
params.permit(:nom, :prenom, :cin, :age, :ville, :telephone, :email)
end
end
I'm sure there is a good and clean way to do that..
Thanks !

I would look at nested attributes for a good clean solution, here is the doc link http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html
There is also a gem that can simplify it for you
