lead.rb

class Lead < ActiveRecord::Base
  attr_accessible :address, :city, :company, :email, :job_title, :name, :phone_number, :state
  validates :name, :presence => true
  validates :email, :presence => true, :format => { :with => /\A[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]+\z/,
                                                    :message => "Valid email only" }
  validates :company, :presence => true
end

Getting this error:

ActionView::Template::Error (undefined method `gsub' for #<Array:0x007fa7544a1d68>):

(Referencing that line:

   console.log("<%= escape_javascript @lead.errors.full_messages %>");

This finally spit it out to the console:

<% @lead.errors.full_messages.each do |error_text| %>
  console.log("<%= escape_javascript error_text %>");
<% end %>

Did that display the proper text? I'm wondering if maybe they weren't properly escaped?

Yes. I know I had them escaped before. I'll try another option at putting them back on the page.
Thanks.

You might try $('#error_explanation').append('<%=content_tag(:, escape_javascript(msg))%>');

I'm missing the p in the content_tag.

Also the escape_javascript might make sense wrapping the content_tag instead too, I'm not sure.
