Twitter has just released their new Tweet button and I wanted to use it in the freelance marketplace I am developing (TaskArmy.com).
It took me literally 5 minutes thanks to the Twitter Button gem from Intridea.
Although the gem worked perfectly locally, I had some issues when I deployed it on Heroku.
1. Install the gem:
gem install tweet-button
2. Add tweet-button to your .gems file
3. Add the following in your environment.rb:
config.gem "tweet-button"
4. Include the module in your ApplicationHelper:
module ApplicationHelper include TweetButton
5. Call the button method in your view:
<%= tweet_button(:via => "taskarmy", :text => task.title, :count => "none") %>
6. That should be it for most of you. When I deployed to Heroku, I had an error saying that the method html_safe didn’t exist in the String class so I simply integrated the code tweet_button.rb of the gem in my project and I added a html_safe function in the class:
def html_safe(text)
return text if text.nil?
return text.html_safe if defined?(ActiveSupport::SafeBuffer)
return text.html_safe! if text.respond_to?(:html_safe!)
text
end
And change the two calls to html_safe in tweet_button.rb to the following:
''.html_safe –> html_safe('')
That’s it!
