26,130,773 | 0 | Make all action methods of a controller ChildActionOnly <p>Instead of having to remember to decorate a bunch of action methods with the <code>ChildActionOnly</code> attribute, it would be convenient to be able to specify all methods in an entire controller as such.</p> <p>Trying to put the <code>ChildActionOnly</code> attribute on the controller class doesn't work (at least in my code context) because during dependency injection for the controllers, which occurs at an early phase in the request pipeline, there is no HttpContext or Request object, and the error "Request is not available in this context" is thrown.</p> <p>Could I create a <code>RouteConstraint</code> that makes the route itself enforce <code>ChildActionOnly</code>? That seems doubtful because of the same request pipeline issue--I don't know if the HttpContext would be available during the time that execution of RouteConstraints occurs. If you have ideas how to implement this, please share.</p> <p>Maybe create a unit test that uses reflection to discover all action methods of a specific controller and ensure they have the <code>ChildActionOnly</code> attribute set...</p> <p>How do I accomplish this?

29,442,452 | 0 | parse cloud code job : delete rows that have been in DB for an hour <p>I'm using parse as a mobile backend for an ios app I'm developing. I know its probably not a permanent solution but for what I'm doing right now it gives me good test results. I need to create a cloud code job which will remove all the rows with entries older than one hour in all of my databases besides one (this DB is just for the sake of having a backup of everything).I want to do this so client side devices can only query for things in the DB that are less than an hour old. I have a "timestamp" on each entry which I was going to incorporate into a js function to first check If all the entries were indeed an hour or more old, and if they were, delete them. I've been doing some research and really havent been able to develop a js function that would do this (I have absolutely no js experience whatSoEver just obj c) from my understanding it would be something similar to this </p> <pre><code> Parse.Cloud.job("deleteRows", function(request, status) { Parse.Cloud.useMasterKey(); var query = new Parse.Query(//inverse of db i dont want to delete from); query.each(function(//row in db?) { // delete here under parameters ? }).then(function() { status.success("rows deleted"); }, function(error) { status.error("job incomplete"); }); }); </code></pre> <p>if anyone could give me a hand I'd really appreciate it.

11,283,433 | 0 | <p>They reduce reusability in much the same way that global variables do: when you method's computations depend on state which is external to the method, but not passed as parameters (i.e. class fields for example), your method is less reusable, because it's tightly coupled to the state of the object/class in which it resides (or worse, on a different class entirely).</p> <p><strong>Edit</strong>: Ok, here's an example to make it more clear. I've used <code>ThreadLocal</code> just for the sake of the question, but it applies to global variables in general. Assume I want to calculate the sum of the first N integers in parallel on several threads. We know that the best way to do it is to calculate local sums for each thread and them sum them up at the end. For some reason we decide that the <code>call</code> method of each <code>Task</code> will use a <code>ThreadLocal sum</code> variable which is defined in a different class as a global (static) variable:</p> <pre><code>class Foo { public static ThreadLocal<Long> localSum = new ThreadLocal<Long>() { public Long initialValue() { return new Long(0); } }; } class Task implements Callable<Long> { private int start = 0; private int end = 0; public Task(int start, int end) { this.start = start; this.end = end; } public Long call() { for(int i = start; i < end; i++) { Foo.localSum.set(Foo.localSum.get() + i); } return Foo.localSum.get(); } } </code></pre> <p>The code works correctly and gives us the expected value of the global sum, but we notice that the class <code>Task</code> and its <code>call</code> method are now strictly coupled to the <code>Foo</code> class. If I want to reuse the <code>Task</code> class in another project, I must also move the <code>Foo</code> class otherwise the code will not compile.</p> <p>Although this is a simple example complicated on purpose, you can see the perils of "hidden" global variables. It also affects readability, since someone else reading the code will have to also search for the class <code>Foo</code> and see what the definition of <code>Foo.localSum</code> is. You should keep your classes as self-contained as possible.</p> |

Basically I have a Google map with a marker embedded in a form; the map is surrounded with input fields.</p> <p>When you tab trough the form fields, at a certain point elements within the map are focused. One of the focusable elements is the <code>area</code> in the <code>map</code> used on the marker image. On Chrome 22 and Firefox 15 I can't see any default focus styling for areas. That annoyed me, so I tried to add some styling. Even without <code>:focus</code> this is <strong>not</strong> working:</p> <pre><code>area { outline: 2px solid red; } </code></pre> <p>Is there a way to style focused Google maps markers?</p> <hr> <p><strong>Edit</strong>: Since styling areas does not work I tried to see if I could bind a focus event listener to the areas. There is no focus event available for <a href="https://developers.google.com/maps/documentation/javascript/reference#Marker" rel="nofollow">markers</a> in the Google Api. So, that's a dead end.</p> <p>When you try to add a listener on areas (without using the Google Api), you will run into the problem that markers aren't placed synchronically and that there is no callback available in the Google Api.</p> <p>You could setup a <a href="https://developer.mozilla.org/en-US/docs/DOM/window.setInterval" rel="nofollow"><code>setInterval</code></a> to add focus listeners to new areas, but I don't like that solution a lot.</p> <p>Does anyone have any other ideas?</p> |

I was hoping to use the <a href="http://perldoc.perl.org/functions/stat.html" rel="nofollow noreferrer">stat</a> function and grab all the information from there. However, the timestamp in the ls output uses the high-resolution clock so it includes the number of nanoseconds as well (according to the GNU docs, this is because --full-time is equivalent to <code>--format=long --time-style=full-iso</code>, and the full-iso time style includes the nanoseconds).</p> <p>I came across the <a href="http://perldoc.perl.org/Time/HiRes.html" rel="nofollow noreferrer">Time::HiRes</a> module, which overrides the standard stat function with one that returns atime/mtime/ctime as floating point numbers, but there's no override for <a href="http://perldoc.perl.org/functions/lstat.html" rel="nofollow noreferrer">lstat</a>. This is a problem, because calling stat on a symlink returns info for the linked file, not for the link itself.</p> <p>So my question is this - where can I find a version of lstat that returns atime/mtime/ctime in the same way as Time::HiRes::stat?

31,391,581 | 0 | How to bind multiple struct fields without getting "use moved value" error? <p>I'm trying to code a generic list as an exercise - I know it's already supported by the syntax, I'm just trying to see if I can code a recursive data structure. As it turns out, I can't. I'm hitting a wall when I want to access more than one field of an owned struct value.</p> <p>What I'm doing is basically this - I define a struct that will hold a list:</p> <pre class="lang-rust prettyprint-override"><code>struct ListNode<T> { val: T, tail: List<T> } struct List<T>(Option<Box<ListNode<T>>>); </code></pre> <p>Empty list is just represented by <code>List(None)</code>.</p> <p>Now, I want to be able to append to a list:</p> <pre><code>impl<T> List<T> { fn append(self, val: T) -> List<T> { match self { List(None) => List(Some(Box::new(ListNode { val: val, tail: List(None) }))), List(Some(node)) => List(Some(Box::new(ListNode { val: node.val, tail: node.tail.append(val) }))) } } } </code></pre> <p>Ok, so that fails with an error "used of moved value: node" at node.tail with an explanation that it was moved at "node.val". This is understandable.</p> <p>So, I look for ways to use more than one field of a struct and I find this: <a href="https://mail.mozilla.org/pipermail/rust-dev/2014-January/008216.html">Avoiding partially moved values error when consuming a struct with multiple fields</a></p> <p>Great, so I'll do that:</p> <pre><code>List(Some(node)) => { let ListNode { val: nval, tail: ntail } = *node; List(Some(Box::new(ListNode { val: nval, tail: ntail.append(val) }))) } </code></pre> <p>Well, nope, still node is being moved at assignment ("error: use of moved value 'node'" at "tail: ntail"). Apparently this doesn't work like in the link anymore.</p> <p>I've also tried using refs:</p> <pre><code>List(Some(node)) => { let ListNode { val: ref nval, tail: ref ntail } = *node; List(Some(Box::new(ListNode { val: *nval, tail: (*ntail).append(val) }))) } </code></pre> <p>This time the deconstruction passes, but the creation of the new node fails with "error: cannot move out of borrowed content".</p> <p>Am I missing something obvious here? If not, what is the proper way to access multiple fields of a struct that is not passed by reference?</p> <p>Thanks in advance for any help!</p> <p>EDIT: Oh, I should probably add that I'm using Rust 1.1 stable.</p> |

22,982,007 | 0 | <p>Under windows, any perl operation that internally tries to test a file or directory for existence uses the Win32 function <code>CreateFile</code>. Under windows a filename ending in spaces is not legal (although not clearly documented), and for some strange reason the <code>CreateFile</code> function internally strips all trailing spaces before trying to open the file/directory.</p> <p>Since a name starting with space looks like a relative path, the space is first appended to your current working directory but then internally ignored by the Win32 function. This results in the directory test seeing your current directory and reporting success. </p> <p>The perl <code>stat</code> function then proceeds to acquiring additional information and seems to somewhere down the line handle the trailing space(s) differently and therefore fails to get any further information. However it seems to explicitly leave the <em>mode</em> attribute of the stat result set, because it earlier had deduced that there existed a directory.</p> <p>So yes, I would call this a bug in the windows port of perl, but fixing it is probably not as easy as it sounds, as there are lots of special cases for UNC paths, reparse points, NTFS/FAT filesystems etc. that makes correct handling of trailing spaces rather tricky.</p> <p>Your best bet would probably be to explicitly strip trailing spaces from any assumed directory name at a very early point (who needs that anyway) and croak if nothing is left after stripping.</p> |

6,190,067 | 0 | <p>Your communication classes shouldn't care what happens to the data they receive. Instead, they should either make the data available to a class that wants it. One way to do so would be to provide a getData() method, which received data and then returned it to the caller. Even better would be to provide a DataArrived event, which was fired whenever you received data. That way, any number of consumers could listen for data, but your communication code doesn`t have to know which classes are listening or what they plan to do with the data.</p> <p><strong>EDIT</strong>:</p> <p>A simple example:</p> <pre><code>public class MyClassWithEvent { public delegate void DataArrivedDelegate(string data); public event DataArrivedDelegate DataArrived; public void GetSomeData() { // Communication code goes here; stringData has the data DataArrivedDelegate handler = DataArrived; if (handler != null) { // If you want to raise the event on this thread, this is fine handler(stringData); } } } </code></pre> <p>In your listener class:</p> <pre><code>public MyListener { public MyListener(MyServer server) { // Sets MyListenerMethod to be called when DataArrived is raised server.DataArrived += MyListenerMethod; } public void MyListenerMethod(string data) { // Do something with the data Console.WriteLine(data); } } </code></pre> |

So your design pattern is not quite right. </p> <p>I think what you need is like when data is changed in ViewModel1, other ViewModels can get notified and response to it, and you may have done this work by manually refresh it and you want to find another way. </p> <p>Here is an easy way to do this in MVVM pattern, you can use the Messenger of <a href="https://mvvmlight.codeplex.com/" rel="nofollow">MVVM Light</a>, you can refer to this question on SO: <a href="http://stackoverflow.com/questions/18087906/use-mvvm-lights-messenger-to-pass-values-between-view-model">Use MVVM Light's Messenger to Pass Values Between View Model</a>.</p> |

35,003,479 | 1 | How to hide part of string in python <p>I am just wondering if there is such possibility to hide somehow part of string in python. I am not talking about slicing. I am talking about situation where I have "1somestring," while printing I obtain "somestring". 1 before somestring should be visible for python but not displayable. Or It could be nice to have some kind of indicator glued to string. What I want to achieve is custom sorting. I have list of strings and I want to sort them by addition of digits in front of them. Sorting will proceed basing on digits thus behind digits I can insert whatever I want, but I don’t want to have digits visible. Thanks for answers in advance.</p> |

24,701,732 | 0 | Optional parameters and method overloading <p>I've come across a library method with three parameters, all with default values:</p> <pre><code>virtual M(bool b1 = false, string s1 = null, bool b2 = true) </code></pre> <p>Method <code>M</code> shouldn't have parameter <code>s1</code>, so I want to remove it, but I don't want to make a breaking change in the DLL. Clients can obviously ignore <code>s1</code>, but I don't want to leave it there because <code>M</code> can be overridden and parameter <code>s1</code> is misleading. So here was my attempt:</p> <pre><code>virtual M(bool b1 = false, bool b2 = true) [Obsolete] virtual M(bool b1, string s1, bool b2 = true) </code></pre> <p>I figured that since optional parameters are compiled into the call site, existing clients would carry on calling the method with three parameters, whereas new or recompiled clients not using <code>s1</code> would link to the method with two parameters.</p> <p>Each call to <code>M</code> resolves okay, except this one:</p> <pre><code>M(b2: false); </code></pre> <p>The compiler reports that the call is ambiguous between "M(bool, bool)" and "M(bool, string, bool)".</p> <p>Oddly, in the parameter info (Ctrl+Shift+Space), Visual Studio is still showing the default values on the method with three parameters (despite cleaning and rebuilding, restarting VS, unloading and reloading projects).</p> <p>Obviously I can fix this by calling the new <code>M</code> something different, but I'm curious as to why it's not linking. Should it (and something's just out of step, as the out-of-date parameter info suggests), or does the compiler have a genuine issue with this?</p> <p>EDIT</p> <p>Like @p.s.w.g and as per @JonSkeet's suggestion, I can't reproduce this in fresh code, so I guess the question becomes: is there anything else I can try other than rebuilding, restarting, reloading to force VS to relink this?</p> |

18,004,680 | 0 | <p>I was actually going slightly crazy about this myself. If the data in the csv is encased in quotes, when SSIS imports csv file it includes the quotes in the output of the rows so you actually have to remove the end quotes yourself. Otherwise you are literally trying to cast the quotes and the number to a float. Passing the output of the CSV import to a derived column control will work for you. </p> <p>In the expression field of the derived column -> (DT_R4)REPLACE([Column Name],"\"","")</p> <p>This removes the quotes then cast the value out to a float.</p> |

14,801,477 | 0 | Mixing backbone.js routers and rails controllers <p>I'm currently attempting to wrap my head around grafting backbone.js into my rails application. For starters, I want to build it into a a specific part of the rails application at /applications. With that said I have a rails resource "resources :applications" which gives me localhost:3000/applications. Now when I instantiate backbone for /applications I get anchor tags for the backbone routing at that rails resource. IE localhost:3000/applications/#applications/5.</p> <p>Given that I'm only going to be using backbone at specific parts of the rails app, thus not making it a single page app, is this the right way to do things? The URL appears to be a bit redundant.</p> <p>The correct answer might be that I need to do away with the backbone router? If so, then how can :id be passed to the backbone application when attempting to look up a collection / model.</p> <p>The point of me using backbone is to help organize a particular section of the rails app that will be javascript heavy.</p> <p>I should mention that I can change the router to something like:</p> <pre><code>routes: '': 'index' ':id': 'show' </code></pre> <p>which will give me the url of localhost:3000/applications/#/1 - however I think this paints me into a corner and will not allow me to use backbone on other rails resources. If I were to have localhost:3000/dashboard with backbone invoked then the wrong backbone.js functionality would get executed.</p> <p>Another thought would be to have an invocation of a backbone router per rails resource. I could use the aforementioned routes code since the router would only be invoked for that rails resource.</p> |
