ruby on rails - What value should I pass to paperclip to make it so that the file does not update? -

-

when update file in app, deletes , re-saves paperclip file. wan't pass in update_attributes allows paperclip ignore it, not delete current file. pass in?

i passing in file, deletes , resaves.

you might using 

class user < activerecord::base    has_attached_file :attachment,   :url => :attachment_url,   :path => :attachment_path,   :default_url => "/images/sheet.png"  end

try adding :preserve_files => false. way when add new file previous file reserved , not deleted.

final result 

class user < activerecord::base    has_attached_file :attachment,   :preserve_files => false,   :url => :attachment_url,   :path => :attachment_path,   :default_url => "/images/sheet.png"  end

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()
