Ruby on Rails Saturday, November 29, 2014


I am trying to create a form that updates 2 tables in my database. I'm not quite sure how to build this contact form quite yet. So my first short term goal is to simply update my `contact_requests` and `users` tables. I am aiming to do a `one to many` relationship between `users` and `contact_requests`. This allows one `user` to have many `contact_requests`. I am new to rails so I feel like there are gaps in my code and I am making some mistakes as well.  Ideally, I will want to include a mailer in the form as well but one step at a time.

I currently have a `user` table and a `contact_request` table: 



`user_id` from the `contact_requests` table is a foreign key that references `users.id`

Here is by current schema code:

    ActiveRecord::Schema.define(version: 20141127114323) do
      create_table "contact_requests", force: true do |t|
        t.datetime "created_at", null: false
        t.datetime "updated_at", null: false
        t.string   "message",    null: false
        t.integer  "user_id"
      end
    
      add_index "contact_requests", ["user_id"], name: "index_contact_requests_on_user_id", using: :btree
    
      create_table "users", force: true do |t|
        t.datetime "created_at",   null: false
        t.datetime "updated_at",   null: false
        t.string   "first_name",   null: false
        t.string   "last_name",    null: false
        t.string   "email",        null: false
        t.string   "phone_number"
      end
    end

Here are my models and controllers:

    class User < ActiveRecord::Base
      has_many :contact_requests
      # validate the presence of the attributes
      validates(:first_name, presence: true)
      validates(:last_name, presence: true)
      validates(:email, presence: true)
    end

    class ContactRequest < ActiveRecord::Base
      belongs_to :user
      validates :user_id, presence: true
      validates :message, presence: true, length: { maximum: 500 }
    end

    class ContactController < ApplicationController
      def new
      @user = User.new
      @contact_request = ContactRequest.new
      end
    end


I am getting this error:

    <%= form_for(:contact, remote: true, class: "contact-input") do |f| %>
          <div class="col-md-12">
            <div class="col-md-6">
              <div class="contact-input-margin form-group">
                <%= f.text_field(:user, :first_name, class: "form-control", placeholder: "First name")%>
              </div>

              </div>
            </div>
          </div>
          <%= f.submit(class: "btn btn-xl") %>
        <% end %>
