Here’s the commit which adds the feature to rspec – This was on May 25 2008. With this you can do A.any_instance.stub(do_something: 23) However, the latest gem version of rspec (1.1.11, October 2008) doesn’t have this patch in it. This ticket states that they yanked it out for maintenance reasons, and an alternative solution hasn’t … Read more
The name of the operator is the null-coalescing operator. The original blog post I linked to that covered the differences in null coalescing between languages has been taken down. A newer comparison between C# and Ruby null coalescing can be found here. In short, you can use ||, as in: a_or_b = (a || b)

Remember that the ID is stored as :_id and not :id . There is an id helper method, but when you do queries, you should use :_id: User.where(:_id.in => arr) Often I find it useful to get a list of ids to do complex queries, so I do something like: user_ids = User.only(:_id).where(:foo => :bar).distinct(:_id) … Read more
This is an error that occurs when two different versions of the model have been loaded. I used to hit it in an older version of Rails 3, since the development environment’s model reloader was slightly glitched. The numbers after the class name refer to different versions of the class. It stands to reason that … Read more
Unfortunately open-uri only supports the GET verb. You can either drop down a level and use net/http, or use rest-open-uri, which was designed to support POST and other verbs. You can do gem install rest-open-uri to install it.
Ruby is telling you that it found an Insurance, but it is not a module. Perhaps you already have defined an Insurance class? Depending on the surrounding code it might help if you “reset” the namespace by prepending a double colon: broker = ::Insurance::Broker::FakeBroker.new(1234,1234)
The debugger gem can be used but it still has issues. Install byebug which was written for Ruby 2.0 debugging. For breakpoints, use the byebug command in your code instead of debugger.
