SO, I cannot determine the problem.  It says first_name cannot be null, obviously because I setup the database that way, but there is a value trying to go into database, even though I can return a value in Rails Console asking for first_name.....  Any advise?


Below are controller/model



***** TENANT CONTROLLER
class TenantsController < ApplicationController

    def index
        render('list')
    end

    def list
      @tenants = Tenant.order("tenants.last_name ASC")
    end

    def show
      @tenant = Tenant.find(params[:id])
    end

    def new
      @tenant = Tenant.new
    end

    def create
        @tenant = Tenant.new(params[:tenant])
        @tenant.save

        if @tenant.save
            flash[:notice] = "New Tenant was created successfully."
            redirect_to(:action => 'list')
        else
            render('new')
        end
    end

    def edit
      @tenant = Tenant.find(params[:id])

    end


    def update
        # find object using form parameters
        @tenant = Tenant.find(params[:id])

        #update the object
        if @tenant.update_attributes(params[:tenant])

            #if update succeeds redirect to
            flash[:notice] = "Tenant was updated successfully."
            redirect_to(:action => 'show', :id => @tenant.id)
            else
            render('edit')
        end

    end

    def delete
        @tenant = Tenant.find(params[:id])

    end

    def destroy
        @tenant = Tenant.find(params[:id])
        @tenant.destroy

        flash[:notice] = "Tenant was destroyed successfully."
        redirect_to(:action => 'list' )

    end


end

***** TENANT MODEL
class Tenant < ActiveRecord::Base
    attr_accessible :first_name, :last_name, :home_id
end

tenant = Tenant.new
=> #<Tenant id: nil, first_name: nil, last_name: nil, home_id: nil, created_at: nil, updated_at: nil>
>> tenant.first_name = "Billy"
=> "Billy"
>> tenant.last_name = "Jones"
=> "Jones"
>> tenant.save

tenant = Tenant.create(:first_name => "Billy", :last_name => "Jones")

first_name = "Billy"

tenant.first_name = "Billy"

puts tenant.errors.full_errors
