i trying write method selects subset of members of user class. here attempt: def self.stats_users(date) self.where("employee = false , last_sign_in_at >= ?", date) end i tried call function in manner: user.stats_user('2011-04-14') however, method executing sql statement: select "users".* "users" (employee = false , last_sign_in_at >= '2011-04-14') when should execute: select * "users" (employee = false , last_sign_in_at >= '2011-04-14') i guess real question revolves around writing methods act on members of class , relative ignorance of put these methods , how call them. appear having little trouble understanding how activerecord transforms statements raw sql. re sql the queries equivalent in case. re methods collections this scopes for: scope :stats_users, lambda { |date| where("employee = false , last_si...

our application requires quite few tools , utilities have written support our product. things data converters, backup utilities etc. currently, each of these utilities separate delphi project. on top of that, many of these projects have corresponding dunit project unit testing, have separate project. have 13 separate delphi projects. these projects in 1 project group. is necessary? have have many separate projects, or there way in delphi have multiple entry points same project? also, convenient during development write code , 'run' it. end hacking project file; commenting out normal behaviour , replacing code want run. way? we use delphi 2010 if makes difference. you can either of these pretty easily: combine projects project group, able work them more easily. (my preference) separate projects different units (instead of project files), create single application uses units, , call different functionality based on command-line parameters (see paramcount ,...

i insert non english (e.g. russian or hebrew) text in view. is idea do: <div>что нибудь по русски</div> or <div><%= "משהו בעברית" %></div> or there better methods ? use rails i18n api. create yaml files translations of specific pieces of code; works amazingly well. here's guide: http://guides.rubyonrails.org/i18n.html if need more complicated, it's doable, rails i18n api 1 of best.

situation: have 2 linux boxes running lamp stack. want access http box1 via box2 (using wget , curl). want people using box2 see no change @ all. what's best solution? need easy setup if possible. you'll have more specific; why users notice anything box2? intention serve content box1 without intermediate processing? or box2 making requests of box1 while in process of generating content users have requested? proxy in question? if want requests made of box2 transparently handled box1 in background, ignore wget / curl , and configure apache mod_proxy . if you're trying build cache of responses box1 served via box2, perhaps running squid in reverse proxy mode makes more sense. it's made caching. :) (building caching application on box1 might better long-term answer; pretty easy in ruby-on-rails applications add fragment caching , page caching application, , memcached can used add model-caching behavior, different caching fragments or whole pages. appr...
