Question

I am really really stuck and annoyed with this right now.

I am running Rails 2.3.5

My View/pages/customers.html.erb simply has:

<% form_tag do %>
    First Name
        <%= text_field_tag :firstName, params[:firstName] %>
    Last Name
        <%= text_field_tag :lastName, params[:lastName] %>

        <%= submit_tag "Enter" %>
<%end%>

My Models/customer.rb simply has:

class Customer < ActiveRecord::Base
    attr_accessible :firstName, :lastName
end

My Controller/pages_controller has

class PagesController < ApplicationController
  def custs
    @cust = Customer.new(params[:firstName], params[:lastName])
    @cust.save
  end
end

so as you see I am just trying to enter two fields from front end and then save them to the DB. However, whenever i load my page it give me error:

wrong number of arguments (2 for 1)
pages_controller.rb:3:in new'
pages_controller.rb:3:incusts’

weird thing is that when I use the sandbox script/console I am able to insert data fine.

What is going on here? please someone explain!

http://apidock.com/rails/ActiveRecord/Base/new/class here is a little explanation of the new function. The crucial part – “pass a hash with key names matching the associated table column name”. Instead of @cust = Customer.new(params[:firstName], params[:lastName]) you should have @cust = Customer.new(:firstName => params[:firstName], :lastName => params[:lastName]). This should do the trick.
