I already wrote a blog on how to use Google maps in rails.  Earlier blog is supported in rails 2.3.x version.

To supoort rails 3 application , certain changes are required in plugin.

Here I will show you what are those changes required.

Download YM4R plugin :

rails plugin install https://github.com/rorcraft/ym4r_gm

1. Add following method in class Varible under gm_plugin/mapping.rb

def to_str
@variable + “;”
end

2. Use raw method for each google maps methods to avoid html contents.

<%= raw GMap.header %>

<%= raw @map.to_html %>
<%= raw  @map.div(:width => 600, :height => 400) %>

4. Add Ym4r js in your layouts

 <%=javascript_include_tag :defaults,"ym4r-gm"%>

5. Commented line no: 35 in ym4r/lib/gm_plugin/map.rb

#   a << "<script src=\"/public/javascripts/ym4r-gm.js\" type=\"text/javascript\"></script>\n" unless options[:without_js]

I hope this blog helps you. Let me know if you still facing any problem.

Here I will show you how to send email through ruby script.

Require NET/SMPT  library  in ruby script

require 'net/smtp'

Config SMTP authentication

def  send_email(to,opts={})

opts[:server]      ||= 'SERVER IP'

opts[:port]        ||= PORT_NUMBER

opts[:domain]      ||= "DOMAIN IP"

opts[:user_name]   ||="USERNAME"

opts[:password]    ||= "PASSWORD"

opts[:authentication]   ||="plain"

opts[:from]        ||= 'example@domain.com'

opts[:from_alias]  ||= 'FROM NAME'

opts[:subject]     ||= "SUBJECT SAMPLE"

opts[:body]        ||= "MESSAGE BODY"

 msg = <<END_OF_MESSAGE

From: #{opts[:from_alias]} <#{opts[:from]}>

To: <#{to}>

Subject: #{opts[:subject]}

Content-type: text/html

#{opts[:body]}

END_OF_MESSAGE
 Net::SMTP.start(opts[:server],opts[:port], opts[:domain],opts[:user_name], opts[:password],opts[:authentication]) do |smtp|

smtp.send_message msg, opts[:from], to

end

end

Now send email by passing arguments.

send_email "EMAIL ADDRESS", :body => "MESSAGE"

I hope this will helps you to send email through script.

If you get following error while extecuting  ruby script/console

/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require’: no such file to load — readline (LoadError)
 from /usr/local/lib/ruby/1.8/irb/completion.rb:10
 from /usr/local/lib/ruby/1.8/irb/init.rb:252:in `require’
 from /usr/local/lib/ruby/1.8/irb/init.rb:252:in `load_modules’
 from /usr/local/lib/ruby/1.8/irb/init.rb:250:in `each’
 from /usr/local/lib/ruby/1.8/irb/init.rb:250:in `load_modules’
 from /usr/local/lib/ruby/1.8/irb/init.rb:21:in `setup’
 from /usr/local/lib/ruby/1.8/irb.rb:54:in `start’
 from /usr/local/bin/irb:13

To solve this issue , you need to install some libraries.

sudo apt-get install libncurses5-dev
sudo apt-get install libreadline5-dev

Then goto ruby source folder and ext/readline folder

cd  <RUBY SOURCE FOLDER>/ext/readline
ruby extconf.rb
make
sudo make install

This will solved your readline error. If you still facing any problem let me know.

Recently I upgrade my rails version from 2.3.2  to 2.3.4 and ruby version from 1.8 to 1.9 .

By changing version of ruby,  I was facing problem in auto complete functionality.

To solve the issue , I applied below patch in lib/autocomeplete_macro_helper.rb file

def auto_complete_result(entries, field, phrase = nil)
return unless entries
items = entries.map { |entry| content_tag("li", phrase ? highlight(entry[field], phrase) : h(entry[field])) }
content_tag("ul", items.uniq.join)
end

I changed content_tag (“ul”, items.uniq) to content_tag(“ul”,items.uniq.join)
