i have problem when try duplicate laravel eloquent model. model has 121 columns , work firebird database, apache 2.2.22, php 5.4.35 , debian. when save method execute new model stored in database, redirect method not execute , browser display "the connection server reset while page loads." in apache logs error "segmentation fault (11)". i try run code artisan command still same error. on windows not work - cli has stopped working. php code: $asort = asort::on($connname)->find($asortid); // new asort_id $newasortid = db::connection($connname) ->table('rdb$database') ->select(db::raw('gen_id(seq_asort, 1) id')) ->lists('id'); $newasort = new asort; $newasort = $asort->replicate(); //$newasort->setrawattributes($asort->getattributes()); $newasort->setconnection($connname); $newasort->asort_id = $newasortid[0]; $newasort->asort_kod = iconv(...

i select data datatable, using following code,but throws exception not familiar with. "index outside bounds of array." tblrooms.select(idroom = 4) value of idroom in thetblroom don't know why causes error. foreach (datarow dr in tblroomcart.rows) { datarow drroom = tblrooms.select("idroom =" + dr["idroom"])[0];//here error in line } as exception says,index out of bounds,you reading first element (with index 0) there no elements in collection. same this: int[] array = new int[0]; int x = array[0];//you exception here add if statement make sure there @ least 1 element,like: int[] array = new int[0]; if (array.length > 0) { int x = array[0]; }

the below expression works - ((fn[n][(take n (range))]) 10) while below throws error - (#([(take % (range))]) 10) why cant return data type function literal ? if absolutely want return "data" anonymous function using # reader macro use do . #(do [1 2]) as @mars said have alternative use vector function. #(vector 1 2)

i have set of tables (mostly denormilized pre-calculated values storages) not linked model, use raw select queries on them. possible use migration frameworks them (for example, want add column , deploy change environments). thanks. you can use usual migrations system. first, create empty migration (in whatever app appropriate). python manage.py makemigrations --empty yourappname then put in whatever runsql operations need (including sql reverting changes, if want). operations = [ migrations.runsql("create ...", "drop ..."), ... ] the result can run right alongside migrations django models. python manage.py migrate

i can't find similar savitzky golay polynomial fit on opencv. standard smoothing operation though, seems should have. know of have? using c++ worth. thanks! -tim it not clear need do: fit or smooth, mentioned both. if need smooth using opencv can try kalman filter (fit in way , smooth), smooth-2d (using 1d-data) or your own convolution smooth kernel 1d+1d using 1d-data kernelx convolution (the fastest way smooth). opencv near real time image , video processing library, , contains common task solvers this, no polynomial fitting among them yet. if need fitting (not smoothing) can use polynomial fitting matrix equation , calculate answer in simple way mat objects in opencv has inv() (inverse) , t() (transpose) functions.
