php - Symfony2: Custom "Entity Validation Checker" controller function for all routes -


premise: users on system need have accepted nda , sla , filled in questionnaire.

conditions:
1) entire system (from /) falls under security firewall in order determine whether user logged in or not.
2) routes under ^/ authenticated anonymously.
3) routes under ^/portal/ required role_user.

implementation: implement custom checker on routes under ^/portal/ (including /portal/, /portal/orders/, /portal/admin/, /portal/admin/orders/, etc) check whether user has accepted nda, , if not not redirect page user can accept nda, check sla , questionnaire.

question: there way implement in symfony2 "check" function gets called first , continues on actual controller function route set up, other manually calling check function in every controller function every route?

complication: nda/sla/questionnaire pages user redirected, need fall under ^/portal/, these must excluded check (either inside check function or in other manner) in order avoid continuous redirect.

to date, found no "generic" framework-level implementation this. solution implement create "checker/redirector" controller function , call in beginning of each controller function pages wished redirect should checks fail.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
