Rails 3: Why an empty nested form generates a hidden input field? -

-
why this: # edit.html.erb <%= form_for @product |f| %> <%= f.fields_for :shop |sf| %> # nothing here <% end %> <% end %> generates hidden input field: <input type="hidden" value="23" name="product[shop_attributes][id]" id="product_shop_attributes_id"> ? relevant controller code: def edit @product = product.find(params[:id]) end it'll because @product you're editing has shop. rails has inserted in fields_for when form submitted, knows shop nested attributes for. it's default nested attributes behaviour.

What Ruby technique does Rails use to make my controller methods render views? -

-
just curious if knows ruby technique used accomplish following in rails framework. if don't write, say, index method on rails controller, rails still render index view file if url matches route. makes sense, because controller inherits parent class, must have own index method. however, if do define index method, , tell set instance variable, still renders appropriate view. example: def index @weasels = weasel.all # if omit line, rails renders index anyway. # if behavior defined in parent class's index method, # seems overriding method, index wouldn't it. # i'm not explicitly calling super method # actioncontroller::base, maybe rails doing that? render :index end in pure ruby, expect have call super behavior. i assume rails uses kind of metaprogramming technique guarantee controller methods call super . if so, can explain it? can point source code this? update as mladen jablanović has pointed out, initial mental model wrong; contro

multithreading - Java Thread: Run method cannot throw checked exception -

in java thread, 'run' method cannot throw 'checked exception'. came across in core java (vol 1) book. can please explain reasoning behind it? can please explain reasoning behind it? yes, because exception throw in run method ignored jvm. thus, throwing there mistake (unless have specific exception handler thread, see the docs that). no reason incite potentially erroneous behaviour. or, example. class mythread extends thread { public void run() { throw new runtimeexception(); } } ... new mythread().start(); // here thread dies silently no visible effects @ edit why can't parent thread 'catch' exception spawned 'child' thread? @chaotic3quilibrium has noted in comment why not: because parent thread has moved on already. new mythread().start(); // launch thread , forget // 1000 lines of code further... = + 1; // exception child thread propagated here?

Testing for overlapping arrays in Ruby -

-
say have array of arrays in ruby, [[100,300], [400,500]] that i'm building adding successive lines of csv data. what's best way, when adding new subarray, test if range covered 2 numbers in subarray covered previous subarrays? in other words, each subarray comprises linear range (100-300 , 400-500) in example above. if want exception thrown if tried add [499,501], example, array because there overlap, how best test this? since subarrays supposed represent ranges, might idea use array of ranges instead of array of array. so array becomes [100..300, 400..500] . for 2 ranges, can define method checks whether 2 ranges overlap: def overlap?(r1, r2) r1.include?(r2.begin) || r2.include?(r1.begin) end now check whether range r overlaps range in array of ranges, need check whether overlap?(r, r2) true r2 in array of ranges: def any_overlap?(r, ranges) ranges.any? |r2| overlap?(r, r2) end end which can used this: any_overlap?(499..501,

vim - CTRL+mouse wheel in gvim (windows) not paging -

i'm loving vim, 1 thing that's bugging me when hold control key , mouse wheel or down, window scrolls when bindings telling page up/down. i'm using exact same vimrc file (and plugins) on 1 of linux machines , ctrl+mouse wheel page down (as opposed scrolling in windows). is there way force gvim response ctrl+mouseup/down event? seems ignoring in windows ='[ in insert mode, pressing <ctrl+v> , holding <ctrl> , , scrolling mouse doesn't input escape sequence, implies it's not possible remap actions scroll wheel. compare, example, <ctrl+v> <ctrl> left click, inserts <c-leftmouse> . there doesn't seem in mouse events beyond clicks either.

Remove everything except regex match in Vim -

my specific case text document contains lots of text , ipv4 addresses. want remove except ip addresses. i can use :vglobal search ([0-9]{1,3}\.){3}[0-9]{1,3} , remove lines without ip addresses, after know how search whole line , select matching text. there easier way. in short, i'm looking way following without using external program (like grep): grep --extended-regexp --only-matching --regexp="([0-9]{1,3}\.){3}[0-9]{1,3}" calling grep vim may require adapting regex (ex: removing \v). using vim's incremental search shows me i've got pattern right, , don't want verify regex in grep too. edit: peter, here's function use. (c register clobber in functions.) "" remove text except matches current search result "" opposite of :%s///g (which clears instances of current search). function! clearallbutmatches() let old = @c let @c="" %s//\=setreg('c', submatch(0), 'l')/g %d _ put

Python / Javascript -- integer bitwise exclusive or problem -

i'm proficient both languages... i'm having problems integer bitwise exclusive or logical operator. in javascript, gives me 1 result, in python gives me another.. go ahead, open python , execute (-5270299) ^ 2825379669 now javascript, same calculation, , alert result or whatever (example @ http://thorat.org/os/js.php ) the results different! have no idea why! i must missing something. javascript's integers 32-bit whereas python automatically converts unlimited length long format when values exceed 32 bits. if explicitly force python not sign extend past 32 bits, or if truncate result 32 bits, results same: >>> (-5270299 & 0xffffffff) ^ 2825379669 1472744368l >>> (-5270299 ^ 2825379669) & 0xffffffff 1472744368l

c++ - What is causing boost::lower to fail an is_singular assertion? -

i getting odd behavior boost::lower, when called on std::wstring. in particular, have seen following assertion fail in release build (but not in debug build): assertion failed: !is_singular(), file c:\boost_1_40_0\boost/range/iterator_range.hpp, line 281 i have seen appear memory errors after calling boost::to_lower in contexts such as: void test(const wchar_t* word) { std::wstring buf(word); boost::to_lower(buf); ... } replacing calls boost::tolower(wstr) std::transform(wstr.begin(), wstr.end(), wstr.begin(), towlower) appears fix problem; i'd know what's going wrong. my best guess perhaps problem has changing case of unicode characters -- perhaps encoding size of downcased character different encoding size of source character? does have ideas might going on here? might if knew "is_singular()" means in context of boost, after doing few google searches wasn't able find documentation it. relevant software versions: boost 1.40.0;
