This is a gem to helper you quick create a share feature in you Rails apps.

• Twitter
• Facebook
• Vkontakte
• Odnoklassniki
• Whatsapp
• Viber

In your Gemfile:

gem 'sh_button'

And install it:

$ bundle install
$ rails generate sh_button:install

You can config config/initializers/sh_button.rb to choose which site do you want to use:

SocialShareButton.configure do |config|
  config.allow_sites = %w(twitter facebook vkontakte)
end

You need add require css,js file in your app assets files:

app/assets/javascripts/application.coffee

#= require sh-button

app/assets/stylesheets/application.scss

*= require sh-button

In Rails 4.1.6 , use @import to require files:

app/assets/stylesheets/application.css.scss

@import "sh-button";

Then you can use social_share_button_tag helper in views, for example app/views/posts/show.html.erb

<%= sh_button_tag(@post.title) %>

To specify sites at runtime:

<%= sh_button_tag(@post.title, :allow_sites => %w(twitter facebook)) %>

And you can custom rel attribute:

<%= sh_button_tag(@post.title, :rel => "twipsy") %>

You can also specify the URL that it links to:

<%= sh_button_tag(@post.title, :url => "http://myapp.com/foo/bar") %>

<%= sh_button_tag(@post.title, :url => "http://myapp.com/foo/bar", :image => "http://foo.bar/images/a.jpg") %>

You will need to test from a live site or Facebook will reject it; localhost will not work.

Yes, you can override social-share-button base css to change the icon size, margin, and form.

In you app/assets/stylesheets/application.scss:

.sh-button .sh-button-item {
  border-radius: 10px;
  height: 30px;
  width: 30px;
  margin-right: 6px;
}
