activerecord - Rails: database not being updated after save is called -

-

i trying create association between 2 objects , save changes database. have included in notice call on object, test if saves after passes true if stament. when check see if update has occurred in data base nothing has changed.

requests_controller.rb 

class requestscontroller < applicationcontroller    before_filter :load_requestable      def accept      @request = request.find(params[:id])      @request.profile.send("#{@belongs_to}=",@requestable)       if @request.save         redirect_to [@requestable, :requests], notice: "request accepted #{@request.profile.send("#{@belongs_to}").name}"      else        render :new      end    end  private    def load_requestable     klass = [company, profile].detect { |c| params["#{c.name.underscore}_id"]}     @requestable = klass.find(params["#{klass.name.underscore}_id"])     @belongs_to = klass.to_s.downcase   end  end

try saving profile directly (since you're modifying it, not request object)

if @request.profile.save   # redirect

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

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...
