append_features(mod) The documentation says: When this module is included in another, Ruby calls append_features in this module, passing it the receiving module in mod. Ruby’s default implementation is to add the constants, methods, and module variables of this module to mod if this module has not already been...

Hello, Rails provide counter cache field for associations, I want a similar cache for totaling up values (say account_balance = sum_of_deposits - sum_of_withdrawals). I was wondering if rails, already has another surprise in store for me, or is there any plug-in or how-to for doing these kind of things. Thanks. -- Surendra Singhi http://ssinghi.kreeti.com, http://www.kreeti.com Read the

Is there such a thing? I have some duplicate methods in my models, can I place them somewhere and call them in to my models, thus keeping DRY? -- Posted via http://www.ruby-forum.com/.

...er/lib/easy_auth/active_support/concern.rb My monkey patch work for what I''m trying to do but I suspect a better implementation would actually have @_dependencies be an array of arrays with each set being the module in the first element then :include or :prepend in the send. Then when `append_features` or `prepend_features` iterates over @_dependencies the send element will be used to call the proper inclusion method. The only wild card is how ClassMethods will get extended. My understanding is that extend will append class methods to the base class. I cannot seem to find a prepend versio...

Hello, I felt annoyed enough when having to redirect user back to their previous location in a hackish way that I wrote this plugin. It avoids storing POST and Ajax request. It also has a facility to specify actions not to store in the history. If you are interested, it''s there: http://blog.cosinux.org/pages/rails-history See you all, Damien -- Damien MERENNE

Starting to feel more confident and code is DRYing up nicely, but I''ve hit a brick wall here and hoping someone can help me. I''ve got a module, TrustRanking, which extends a number of model''s instance methods, and I want to extend their class methods too, but I can seem to work out how to do it. Simply including the module from the class works a treat for the

...Rails to work with that table quit good. Except for the destroy() action. From the resulting trace I can see that the old version of destroy() is called from transaction.rb.

...end User.send(:include, MyUser::Acts::Chicken) This just mixes in the new method. But if I add a ''has_many'', I get an error.

...d it is a little confusing when the order of things is typically to put included at the top even though it isn''t evaluated before ClassMethods is extended, etc. I''m not sure if it would help, but would be nice if the order of the following that happen in Concern''s def append_features(base) method were different and maybe then I could just override things in the ClassMethods module for class methods and the main block of the module for instance methods: super base.extend const_get("ClassMethods") if const_defined?("ClassMethods")...

So I''ve googled my brains out, and I see a lot of talk about TextHelper for views, but next to no discussion about cleaning text _before_ it is saved. I figured this had to be asked 4 zillion times, but I''m not finding anything concrete/obvious. Using h is fine as a safety catch, but that alone is not acceptable to me as the means of diffusing the impact of HTML or JS
