ruby - How to catch Errno::ECONNRESET class in "case when"? -

My application (Ruby 1.9.2) can increase individual exceptions, including Net-connection Breaks. I rescue exception => E , then case / when to handle them in defferent ways, but many errors go directly from my code to else .

  Rescue exception = & gt; EP e. Class case e Class when Earno :: Econressetti P1 when Erro :: Econnesseti, Erro :: Unicorned, Erro :: ETMDougou P2 and P3 End and  

Prints:

erro :: ekonnetase 3

This is because === Operator works on the case statement on class class

== = against which object Assessment if you want to test for the e category , You just e , not e.class . This is because because in e.class the case falls, because, okay, e.class is a class.

  Rescue exception = & gt; E-Case E When Earno :: Econaressetti P1 When Arro :: Econaressetti, Erro :: Unicorned, Erro :: ETMDougou P2 and P3 End and  

Yes, there is a strange wording in Ruby Occasionally
