You have your Rails Apps with specific Gemsets in RVM.
The following commands creates a wrapped unicorn_rails bin. Be sure to replace the variables and that you have unicorn in your bundle.
rvmsudo rvm wrapper [RUBY VERSION]@[GEMSET] [GEMSET] unicorn_rails
Now you have a /usr/local/rvm/bin/[GEMSET]_unicorn_rails I will refer to [GEMSET]_unicorn_rails as [WRAPPED_NAME]
| #Model | |
| @user.should have(1).error_on(:username) # Checks whether there is an error in username | |
| @user.errors[:username].should include("can't be blank") # check for the error message | |
| #Rendering | |
| response.should render_template(:index) | |
| #Redirecting | |
| response.should redirect_to(movies_path) |
I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.
If you want to roll up all of these into a single jQuery plugin check out Sharrre
Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.
