javascript - Ng-repeat doesn't show data -


I'm very new to Angular JS and at the moment I'm learning PHP rental service with Engels. I had a problem, why was my response data in NG-DROP?

This code structure is: 

  & lt; html ng-app = "ngTest" & gt; & Lt; Top & gt; & Lt; Title & gt; Angular Test & lt; / Title & gt; & Lt; Script type = "text / javascript" src = "http://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js" & gt; & Lt; / Script & gt; & Lt; Script type = "text / javascript" src = "https://code.angularjs.org/1.0.7/angular-resource.js" & gt; & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; div ng-controller = "getctrl" & gt; & Lt; Ul & gt; & Lt; li ng-repeat = "User in User" & gt; {{User.email}} & lt; / li & gt; & Lt; / Ul & gt; & Lt; / Div & gt; & Lt; Script type = "text / javascript" & gt; Var ngTest = angular.module ('ngTest', []); NgTest.factory ('GetFactory', function ($ http) {var user = []; var factory = {}; factory.getusers = function () {$ http.get ('api / get.php'); Users Return;}; return factory;}); NgTest.controller ('GetCtrl', function ($ radius, GetFactory) {$ scope.users = GetFactory.getUsers ();}); & Lt; / Script & gt; & Lt; / Body & gt; & Lt; / Html & gt;   
 PHP code includes Dummy Basic Jason response data:  
   'admin321',); $ Jsonen = json_encode ($ dummy data); Print_r ($ jsonen); ? & Gt;   
 What's wrong here?  
  Update : Please answer the coded. Thank you.  
 
 
 
 No  $ data  variable is not defined.  
 It should be  
  $ jsonen = json_encode ($ dummyData); Instead of   
  
  $ jsonen = Json_encode ($ data);

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
