I have a model called Contact. I have added the following method: def all_completed_events # for a given Contact, return all contact_events records that exist and where sugarcrm = false return (self.contact_letters + self.contact_postalcards + self.contact_emails + self.contact_voicemails + self.contact_calls) end What is mis...
I am experimenting with mongodb 1.6 and this thing is new to me. I notice that if I shard a collection, and then do a mapReduce, mapReduce doesn't accept the argument scope anymore: // some line in some example code... res = db.data.mapReduce(m,r,{scope: {log : log, padZero: padZero}}); And I got an error like this: Mon Aug 09 1...
My question is related to this question. #include<iostream> template< typename T > class T1 { public: T i; void display() { std::cout<<i<<"\n"<<j<<"\n"<<k; } protected: T j; private: T k; friend void Test( T1 &obj); }; template<typename T> void Test(T1<T> &obj) { T a=T(); obj.i=a; obj.j=a; ...
Hi, on a website i want to do this: (simplified) myHandlers = new Array(); for(var i = 0; i < 7; i++) { myHandlers.push(new Handler({ handlerName: 'myHandler'+i, // works, e.g. ->myHandler1, 2, 3 etc. handlerFunc: function(bla) { /*...*/ alert(i); } // doesn't work,all return 7 } } I could set the counter as another attrib...
So, I ask this question in the context of a basic text input function I see in a C++ book: char *getString() { char temp[80]; cin >> temp; char * pn = new char[strlen(temp + 1)]; strcpy(pn, temp); return pn; } So temp declares an array of 80 chars, an automatic variable whose memory will be freed once getString() r...
I just recently learned about Scope Guard C++ idiom. Unfortunately I can't find any good implementation of it. Can anyone point me to some good and usable Scope Guard implementation in C++? Thanks, Boda Cydo. ...
How do I access overridden members of base classes of base classes? #include <iostream> using namespace std; class A {public: char x; A(){x='A';};}; class B1 : public A {public: char x; B1(){x='B';};}; class B2 : public A {public: char x; B2(){x='B';};}; class C : public B1, public B2 {public: char x; C(){x='C';};}; int main(){ C ...
If I want to give a JavaScript variable global scope I can easily do this: var myVar; function functionA() { myVar = something; } Is there a similarly simple and clean way -- without creating an object -- to separate the "declaring" and the "defining" of a nested function? Something like: function functionB; // declared wi...
Dear Masterminds, I'm currently wondering if there is a better solution than passing this scope to the lambda-function via the parameter 'e' and then passing it to 'funkyFunction' using call()-method setInterval(function(e){e.funkyFunction.call(e)}, speed, this) (Minor question aside: I'd been reading something about memory-leaks in ...
I have been thinking a lot lately about how code gets organized in a layered way. I have been thinking of four different ways: Instantiation -- specifically objects are instances of classes. However, in several languages (like python), classes are also objects that were instantiated from a metaclass. So you can end up with an instan...
I guess this is a really simple question and, probably, one that has been answered several times over. However, I really do suck at C++ and have searched to no avail for a solution. I would really appreciate the help. Basically: #ifndef ANIMAL_H #define ANIMAL_H class Animal { public: void execute(); void setName(char*); Anima...
I have the following Javascript function that should return an array of groups that are in database. It uses $.getJSON() method to call get_groups.php which actually reads from the database. function get_groups() { var groups = []; $.getJSON('get_groups.php', function(response) { for (var i in response) { gr...
Hello I'm handling cookies using JavaScript to store some values in my asp.net web application. I use document.cookie to save some values (converted into a lengthy string). But i want that value to be accessible across all the pages in my application. When i try to get that value from a different page, i get the values pertaining to t...

Hello everyone, I would like to ask you some help in clarifying a few issues. But, before anything, some code is inbound first - it's a really simple login example I've constructed. Container is Tomcat 5.5.27. Let's assume correct username and pass combination is entered; questions are at the bottom. LoginPage.jsp (entrypoint - view)...
For lift development, I sometimes need to use match–case statements like the following. (Rewritten to plain scala for easier understanding.) One note to them: These are actually different partial functions, defined in different parts of the code, so it’s important that a case statement fails in or before the guard in order to have the ot...
Hi there, can anyone explain the following to me. I have two JavaScript functions defined in global scope as follows: var foo = function () { var that = this; that.toString = function () { return "foobar" }; return that; }(); alert(foo.toString()); var foo2 = function (foo) { var that;...
The following line works as expected, but I am a little concerned why: getLine >>= \x-> getLine >>= \y-> return [x, y] Consider the addition of parenthesis to scope the lambda expressions: getLine >>= (\x-> getLine) >>= (\y-> return [x, y]) The second line is errorneous because x is not in scope when used in the return, and I am ha...
Hey guys I'm having a problem limiting the scope of a jQuery selector. I've created a slideshow widget that depends on an unordered list for a structure as follows: <ul id="caption"> <li class="visible"> <p> SwitchPoint Solutions is a leading provider of automated configuration solutions fo...
I want to create an object from a class that I have created. What I have been trying is to create the object (which can be testingclass) from a method of another class, which I will call classexample, but it says that testingclass is undeclared, which I assumed meant that it was out of the scope of the method, and the method couldn't ac...
