Question

I’m new to Ruby on Rails, and as my first project I’m creating a beta sign-up page for my startup. I just want to save the users email address to a database for future use, and I am not able to persist any data into my database. I can add emails through the rails console, but my form/controller are not working. What’s wrong?

User Model:

class User < ActiveRecord::Base
  attr_accessible :email

  before_save { |user| user.email = email.downcase }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX }, uniqueness:
 {case_sensitive: false }

end

User Controller:

class UsersController < ApplicationController


  def index

  end



  def create
    User.create params[:email]

    redirect_to :back, :notice => "Success!"


  end

end

Home page HTML:

<h1>######</h1>
<p>Welcome to #####! Give us your email address, and we'll keep you informed on our
latest happenings.
You'll also be placed on the list for our private alpha and beta testings.</p>

<%= render 'form' %>

Form Partial:

<%= form_for User.new do |f| %>
<%= f.label :email %>
<%= f.text_field :email %>
<%= f.submit %>
<% end %>

Thanks!

Answer 1

This is wrong:

User.create params[:email]

It should be:

User.create params[:user]
