Rails Routes based on condition -

-

i have 3 roles: instuctor, student, admin , each have controllers "home" view.

so works fine,

get "instructor/home", :to => "instructor#home" "student/home", :to => "student#home" "admin/home", :to => "admin#home"

i want write vanity url below route based on role of user_id correct home page.

get "/:user_id/home", :to => "instructor#home" or "student#home" or "admin#home"

how accomplish this?

you can't routes because routing system not have information required make decision. rails knows @ point of request parameters , not have access in database.

what need controller method can load whatever data required, presumably user record, , redirects accordingly using redirect_to.

this standard thing do.

update:

to perform of within single controller action need split logic according role. example is:

class homecontroller < applicationcontroller   def home     case     when @user.student?       student_home     when @user.admin?       admin_home     when @user.instructor       instructor_home     else       # unknown user type? render error or use default.     end   end  protected   def instructor_home     # ...     render(:template => 'instructor_home')   end    def student_home     # ...     render(:template => 'student_home')   end    def admin_home     # ...     render(:template => 'admin_home')   end end

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...
