ruby on rails - Nested Form, "Can't mass-assign protected attributes" -

-

this relevant part of nested form:

<div class="field"> <%= f.fields_for "@partcode" |p|%>     <%= p.label "partcode"%><br />   <%= p.text_field :partcode %>  <% end %> </div>

and have in model:

attr_accessible :partcode,                 :description

yet when enter in form, error:

can't mass-assign protected attributes: @partcode

here partcode model:

class partcode < activerecord::base  attr_accessible :partcode,               :description    validates       :partcode,               :description,               :presence => true   belongs_to "goods_ins"   accepts_nested_attributes_for "goods_ins"   end

and here code goods in model:

class goodsin < activerecord::base   attr_accessible :c4lpono,                :courier,                :deliverydate,                 :deliverynoteno,                 :description,                 :destination,                 :notes,                 :partcode,                 :quantity,                 :signedby,                 :suppliername    validates       :deliverydate,                 :deliverynoteno,                  :destination,                :quantity,                 :signedby,                 :suppliername,               :presence => true   has_many :suppliers   has_many :partcodes   accepts_nested_attributes_for :partcodes end

also here new part of partcode controller:

def new @partcode = partcode.new  respond_to |format|   format.html # new.html.erb   format.json { render :json => @partcode } end end

should'nt have :partcode_attributes attr_accessible(in goodsin model), this:

attr_accessible :partcode_attributes

assuming model association configured way. hope helps

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
