javascript - node.js res.json messed up -


First I request an '/ init' and the response is {"x": 50} , Then I request a '/ user' and the response is {"x": 50, "data": "jack"} . There is no problem till now, but if I make an init again, then it reacts to a {"x": 50, "data": "jack"} possible? 

  var resp.success = {"x": 50} exports.init = function (rick, ridge) {res.json (resp.success)}; Export.user = function (req, res) {user.findOne ({_ id: "1234"}) exec (function (err, user) {var response = resp.success; response.data = user.name; res Jason (reaction);}); };    
 
 
 Because you defined var resp.success = {"x": 50} In a scope outside @init and @user methods, when you modify / read resp.success in those ways, they are reaching a shared object instance of resp.success. You can set it independently within the @init method and define resp.success:  
  exports.init = function (req, res) {var resp.success = {" X ": 50} res.json (resp.success)}; Export.user = function (req, res) {var resp.success = {"x": 50} User.findOne ({_ id: "1234"}) exec (function (error, user) {var response = resp. Success; response.data = user.name; res.json (feedback);}); };   
 If you use the Underscore JS Library, you can do anything like this:  
  var resp.success = {"x": 50} Export Init = function (req, res) {var successResponseForThisRequest = _.clone (res.success); Res.json (resp.success)}; Export.user = function (req, res) {user.findOne ({_ id: "1234"}) exec (function (err, user) {var successResponseForThisRequest = _.clone (res.success); response.data = user .name; res.json (feedback);}); };

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. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

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...
