I\'m new to all three, and I\'m trying to write a simple contact form for a website. The code I have come up with is below, but I know there are some fundamental problems with
#{} is interpolation that is used inside "". Just using it outside for a variable assignment won't work.
It would be more likely to be used like this:
number_of_people = 15
Puts "There are #{number_of_people} scheduled tonight"
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 42
end
a =
b =
foo(a,b)
will set a and b to 42.
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
I've created an example of this in two parts that is available on github. The signup form app is here: signup-form-heroku and an example of the static website that interacts with this is here: static-website-to-s3-example. The form app is built using Sinatra and is ready to deploy straight onto Heroku. The static site is ready to deploy straight to S3 and use amazon cloudfront.
