Contact form in ruby, sinatra, and haml

I figured it out for any of you wondering:

haml:

%form{ :action => "", :method => "post"}  %fieldset    %ol      %li        %label{:for => "name"} Name:        %input{:type => "text", :name => "name", :class => "text"}      %li        %label{:for => "mail"} email:        %input{:type => "text", :name => "mail", :class => "text"}      %li        %label{:for => "body"} Message:        %textarea{:name => "body"}    %input{:type => "submit", :value => "Send", :class => "button"}

And the app.rb:

post '/contact' do        name = params[:name]        mail = params[:mail]        body = params[:body]        Pony.mail(:to => '*emailaddress*', :from => "#{mail}", :subject => "art inquiry from #{name}", :body => "#{body}")        haml :contact    end

In case anyone can use this, here is what you might need to use your gmail account to send mail.

post '/contact' do require 'pony'Pony.mail(   :name => params[:name],  :mail => params[:mail],  :body => params[:body],  :to => 'a_lumbee@gmail.com',  :subject => params[:name] + " has contacted you",  :body => params[:message],  :port => '587',  :via => :smtp,  :via_options => {     :address              => 'smtp.gmail.com',     :port                 => '587',     :enable_starttls_auto => true,     :user_name            => 'lumbee',     :password             => 'p@55w0rd',     :authentication       => :plain,     :domain               => 'localhost.localdomain'  })redirect '/success' end

Note the redirect at the end, so you will need a success.haml to indicate to the user that their email was sent successfully.

Uhmm, i tried in irb the following:

foo = #{23}

Of course it wont work! the '#' is for comments in Ruby UNLESS it occurs in a string! Its even commented out in the syntax highlighting.What you wanted was:

name = "#{params[:name]}"

as you did in your solution (which is not necessary, as it already is a string).

Btw, the reason why the code does not throw an error is the following:

a =b =42

will set a and b to 42. You can even do some strange things (as you accidentally did) and set the variables to the return value of a function which takes these variables as parameters:

def foo(a,b)    puts "#{a.nil?} #{b.nil?}" #outputs 'true true'    return 42enda =b =foo(a,b)

will set a and b to 42.
