Rails 4 - Assigning values for a row in an associated table in a form

Question

Beginner of rails here, for my project I need to create a client with things such as first name, middle name, last name and their passport. I have another table called passports that will store the passport. I want to be able to add a passport number in association with the client. Here are the relevant pieces of code:

Controller for Client

def new
  @client = Client.new
end
def create
  @client = Client.new(client_params)
  if @client.save
    redirect_to root_url
  else
    render 'new'
  end
end

private
  def client_params
    params.require(:client).permit(:firstname, :middlename, :lastname, :PresentAddress)
  end
end

Controller for Passport

def new
    @passport = Passport.new
end
def create
    passport = Passport.new(passport_params)
    if @passport.save
        flash[:notice] = "Passport saved"
    else
        flash[:notice] = "Passport not saved"
    end
end
private
    def passport_params
        params.require(:passport).permit(:idnumber, :country)
    end
end

Model for Client

has_one :passport, foreign_key: "client_id"

Model for Passport

belongs_to :client

Migration file for client

create_table :clients do |t|
  t.string :firstname
  t.string :middlename
  t.string :lastname
end

Migration file for passport

create_table :passport do |t|
  t.string :passport
end

/clients/_form.html.erb

<%= form_for(@client) do |f| %>
  <%= f.label :"First Name"%>
  <%= f.text_field :firstname%>
  <%= f.label :"Middle Name"%>
  <%= f.text_field :middlename%>
  <%= f.label :"Last Name"%>
  <%= f.text_field :lastname%>
<%= f.submit "Create Client" %>
<% end %>

/passport/_form.html.erb

<%= form_for([@client, @client.passport.build]) do |f| %>
    <%= f.label :"Passport ID Number" %>
    <%= f.text_field :idnumber %>
    <% f.submit "Create Passport" %>
<% end %>

/clients/new.html.erb

<%= render "clients/form" %>
<%= render "passports/new" %>

I want to be able to create a passport for the client in this form and send it to my Postgres database. How would I go about doing that? Please let me know if I'm missing any other information.

EDIT - changed to a field that's more simple for now. Also modified to do what ChiefrockaChris suggested.

The way to do this would be to put your #_form.html.erb view for addresses under your address views folder and then to render it as a partial in your client#create, client#update etc. view. So for example:

#clients/_form.html.erb
<%= form_for(@client) do |f| %>
  <%= f.label :"First Name"%>
  <%= f.text_field :FirstName%>
  <%= f.label :"Middle Name"%>
  <%= f.text_field :MiddleName%>
  <%= f.label :"Last Name"%>
  <%= f.text_field :LastName%>
  <%= f.label :"Present address"%>
  <%= f.text_field :PresentAddress %>
<%= f.submit "Create Client" %>
<% end %>

Then in your address views folder

#addresses/_form.html.erb
<%= form_for ([@client, @client.addresses.build]) do |f| %>
  <%= f.label :"Street Name"%>
  <%= f.text_field :street_name%>
<%= f.submit "Create Address" %>
<% end %>

Then on client#new:

#client/new.html.erb
<%= render "clients/form" %>
<%= render "addresses/form" %>

Also be sure that there is something in your address#create method that will reference the user creating so it saves in the database as such. Also please do not capitalize your attribute names.
