i trying create array of tuples in swift each tuple contains (1)letter , (2)array of custom objects, when try append throws error 'int' not convertible 't'. here simplified code: var tuples : [(letter : character , objects : [myobject])] = [] //this works tuples.append(letter:"test".firstchar(), objects: [myobject(), myobject()]) //gives error => 'int' not convertable 't' on append function var arrayofobjects : [myobject] = [] tuples.append(letter:"test".firstchar(), objects: arrayofobjects) this should work: let arrayofobjects : [myobject] = [] tuples.append(letter:"t", objects: arrayofobjects) as can see, arrayofobjects constant. problem here might stem fact append expects constant parameter t , while passing tuple containing var . imho makes append goes little crazy, , compiler gives crazier error description ;-)

downloaded junit-4.12.jar , hamcrest-core-1.3.jar (both latest time being), when try run unit tests, exception private (or protected) fields attribute parameter . when change fields public, fine. any comments? sorry mistake, parameterized test documentation defines fields public.

quote the c++ standard library: tutorial , handbook : the portable way of using templates @ moment implement them in header files using inline functions. why this? (clarification: header files not only portable solution. convenient portable solution.) it not necessary put implementation in header file, see alternative solution @ end of answer. anyway, reason code failing that, when instantiating template, compiler creates new class given template argument. example: template<typename t> struct foo { t bar; void dosomething(t param) {/* stuff using t */} }; // somewhere in .cpp foo<int> f; when reading line, compiler create new class (let's call fooint ), equivalent following: struct fooint { int bar; void dosomething(int param) {/* stuff using int */} } consequently, compiler needs have access implementation of methods, instantiate them template argument (in case int ). if these implementations not in header, wouldn...

i have following db::select statement: db::select("select user_id, count(*) orders_count order_book ob session_id='".$session_id."' group user_id"); which result like: [{ "user_id": 2, "orders_count": 6 }, { "user_id": 340, "orders_count": 83 }, { "user_id": 341, "orders_count": 88 }] what equivalent statement using eloquent model? this have far: order::wheresession_id($session_id)->select('user_id','count(*)')->groupby('user‌​_id')->get(); you can use this: order::select('user_id', db::raw('count(*) orders_count')) ->where('session_id', $session_id) ->groupby('user‌​_id') ->get(); you need use db::raw when using count in query's select, because otherwise quoted pdo.
