I'm trying to figure out how to rescue syntax errors that come up when eval()ing code in Ruby 1.8.6. I would expect the following Ruby code: #!/usr/bin/ruby good_str = "(1+1)" bad_str = "(1+1" # syntax error: missing closing paren begin puts eval(good_str) puts eval(bad_str) rescue => exc puts "RESCUED!" end to produ...
Hi, I have several Rescues defined for possible faults, however I am unable to access the ViewData to populate it with things we need the masterpage requires to render. Is this hidden away in a controller we can utilise? Thanks, ...
When writing the "create" method for an object in a Ruby on Rails app, I have used two methods. I would like to use one method for the sake of cleaner and more consistent code. I will list the two methods below. Does anyone know if one is better than the other? If so, why? Method 1: def create1 # is this unsecure? should we grab ...
I have a number of controllers in my Ruby on Rails apps with a rescue handler at the end of the action that basically catches any unhandled errors and returns some kind of "user friendly" error. However, when I'm doing rake test I'd like to have those default rescue handlers disabled so I can see the full error & stack trace. Is there an...
This is somewhat of a broad question, but it is one that I continue to come across when programming in Ruby. I am from a largely C and Java background, where when I use a library function or method, I look at the documentation and see what it returns on error (usually in C) or which exceptions it can throw (in Java). In Ruby, the situa...

I'm using some ruby code wrapped in a begin - rescue block but somehow it manages to still crash. the block of code looks like this: # Retrieve messages from server def get_messages @connection.select('INBOX') @connection.uid_search(['ALL']).each do |uid| msg = @connection.uid_fetch(uid,'RFC822').first.attr['RFC822'] begin...
In ruby, begin # ... rescue # ... end won't catch exceptions that aren't subclasses of StandardError. In C, rb_rescue(x, Qnil, y, Qnil); VALUE x(void) { /* ... */ return Qnil; } VALUE y(void) { /* ... */ return Qnil; } will do the same thing. How can I rescue Exception => e from a ruby C extension (instead of just rescue => e)...
