ruby on rails - Rake Task doesn't load Model with Paperclip -

-

in rake task production migrate assets want require model uses paperclip. error

nomethoderror: undefined method `has_attached_file' #<class:0x00000006c12680> ~/.rvm/gems/ruby-2.0.0-p247/gems/activerecord-3.2.18/lib/active_recor/dynamic_matchers.rb:55:in `method_missing' /app/models/user.rb:74:in `<class:user>'

line 74 declares attachment:

has_attached_file :photo, styles: { original: '1024x1024>', s64: ["64x64#", "jpg"] }, :convert_options => { original: "-quality 85 -strip", s64: "-quality 85 -strip" }, processors: [:trimmer, :cropper], url: '/system/product/:attachment/:id/:style/:filename', path: ':rails_root/public/system/product/:attachment/:id/:style/:filename'

from rakefile: lib/task/asset.rake

task :preload => :environment    require 'user' end

i tried require 'paperclip' before 'user', didn't help.

the problem seemed have beeen unfourtune choice of namespace "assets", seems interfere rails defining namespace already. ends here similiar question: try changing namespace unique , see if error disappears :)

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

-
