...rrassed of it so I won''t show it here). Is there already something like this out there? Also, is there any way I can make my code more Ruby-fied? Here''s what I have so far: --application.rb private #this could probably stand to be renamed def dynamic_conditions_from_hash(some_hash, model) model = Class.new(model) some_hash.delete_if { |key, value| not model.column_names.include? key } conditions_from_hash(some_hash) end def conditions_from_hash(some_hash) condition = '''' some_hash.each_pair {|key, value| if value.empty? n...

Hi everyone, Does Ruby support variable variables like PHP (http://www.php.net/manual/en/language.variables.variable.php)? Or do I have to use eval, like some_hash.each_pair{|key, pair| eval "#{key} = #{value}" } Or is there some other way? I''m actually trying to figure this out in order to use ez_where to create its conditions from a hash, so if this isn''t even necessary could someone let me know? Thanks, Daniel

Hi all, I have a hash that is created in the index method of my controller. After it is created, the index.rhtml page is rendered.

Do you have any ideas? Thanks for your help on this! html

...ause problems. I think the value of the attribute bool should always be accessed by bool? , but I need to get and set the value of the attributes in @attribs like this: get: @item.attribs.each {|a| puts @item.send(a)} set: @item.attribs.each {|a| @item.send(a.to_s + ''='', some_hash[a])} in the get part the method that gets called by send is @item.bool and not @item.bool?. Another issue is validation: should I use validates_inclusion_of :bool? , :in=>[false,true] or validates_inclusion_of :bool , :in=>[false,true] or validates_inclusion_of :bool , :in=>0...

Hello, I''m having some difficulty with using sessions. Basically, I''d like to be able to store a hash in an action: def action session[:details] = {:value => some_hash, :session_path => "/main"} end I''d like to be able to retrieve the hash in another action under the same "main" controller. I retrieve it by doing the following: def action2 hash = session[:details] v1 = hash[:name] # Problem is that this is null end I'...

If we do add an argument to get(), then it should be named consistently with the ifnotfound argument of mget(). As mentioned, the possibility of a NULL value is problematic. One solution is a sentinel value that indicates an unbound value (like R_UnboundValue). But another idea (and one pretty similar to John's) is to follow the SYMSXP design at the C level, where there is a structure that
