  • Using attribute text value in AngularJS directive

    - by C1pher
    Using a YouTube tutorial created by John Lindquist, I was able to create a directive using a template. See fiddle: http://jsfiddle.net/37PSs/ Now, I want to use the value of the attribute as a variable to a function call. Something like this: html: <hello-world name="World"></hello-world> javascript - directive: template: '<span>myFunction({{name}})</span>' javascript - myFunction(theirName): return ("Hello, " + String(theirName) + "!"); The closest I've been able to get is passing an [object Window] to my function.

  • Using readfile() with remote URL and SSL

    - by ColmF
    I have a php-based website that uses SSL and requires a a user to login before accessing any page. I would like to allow access to this site from another domain, so that the functionality remains the same, but the look, feel and domain changes for the user (with the added advantage that I have to maintain only one version of the code). Having done some reading, I'm using readfile() function calls in php files on the secondary server to corresponding files on the primary server. For example, the login.php on the primary server is accessed from the secondary server by a file called login.php containing readfile("http://www.primarydomain.com/login.php") (and nothing else). Now the problem - I can't even login! The login page appears fine when called initially, but when login user and pwd are entered and submitted, it's as if the remote server doesn't see the $_SERVER['REQUEST_METHOD'] variable that triggers form processing and just loads as an empty form. Any ideas what I'm doing wrong or what configuation I might need to change? Thanks!

  • EJB3 Caching Instance Variables

    - by Justin
    Hi, I've noticed some strange code on a project I am working on - its a SLSB EJB3, and it uses a private instance variable to maintain a cache of data (it even calls it dataCache or something), with a getter/setter. For EJB2 and bellow, this was a typical EJB antipattern - SLSBs are not meant to retain state in between invocations, theres no guarantee you'll see the same data on a subsequent invocation. One of my colleagues said maybe its ok in EJB3 (we don't have much EJB3 experience), but still, its a Stateless Session Bean - why is it trying to maintain state, this doesn't make sense. Can anyone confirm if this is still a bad idea in EJB3 land, or if somehow it is ok? Thanks if you can help, Justin

  • Porting from GAE to TomCat or another servlet server

    - by bach
    Hi guys, I'm unhappy from GAE because - One can't have a global variable and the 'synchronize' keyword. Instead one have to catch a basically DB transcational exception and retry in a while loop - which will eat all my free CPU time and will start costing me money as I reach the google's qouata. Is it safe to use synchronize inside a doPost() in tomcat? (i guess that it's ok as long as all the servlets are running on on 1 VM?). If not in all tomcat configurations, how do I configure tomcat to make it safe? How can I convert a GAE app to my own tomcat server? - How to install DataNucleus Access Platform on tomcat? Best regards

  • Shell Script Sequencing with Rake

    - by Haseeb Khan
    Hi All, I am working on a rake utility and want to implement something mentioned below: There are some shell commands in a sequence in my Rake file. What I want is that the sequence should wait for the previous command to finish processing before it moves to the next one. sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end sh "git push heroku master" So, in the above example what I want is that sh "git push heroku master" shouldn't be executed until the processing in the sh "git commit -m \"#{args.commit_message}\"" do |ok, res| # Do some processing end is completed. Also another nice to have would be that if I can store the output of the shell command in a Ruby variable so it can be used in further manipulation if required. Looking forward to a reply from the fellow community member shortly. Thanks in advance.

  • Consultant "branding" problem

    - by James Jones
    Where I work, we employ a consultant to do a considerable amount of work for us to hold us over until we can hire/train more staff. He has been working with us for quite a long time now, and he has always had this strange habit of leaving his initials on EVERYTHING he touches, as if its his sort of branding or advertising. And by everything, I mean: Database names Table names Variable names Web service names File names Server names etc... Is this a common practice among consultants? We politely asked if he could remove some of the branding, but he typically scoffs and quotes exorbitant time estimates to perform such 'silly' refactorings. I guess we could leave it alone, but it's really annoying to have to type out his name every time we reference something he made. Any recommendations on how to approach this problem? Edit: Our contract with him states that we "own" everything he makes for us.

  • VB.net Edit-And-Continue: ignore "unable to apply this change while debugging"

    - by FastAl
    When using VB.Net (2008) and paused in debugging, Edit-And-Continue is a great time-saver. However if you change any module/class-level information (variable, sub/function signature, etc), you get the error message like this: "unable to apply this change while debugging" While I can understand the technical challenge to making this work (and why it would be hard), it leaves me in a tight spot with just a few options: 1) Restart and recompile and get the program back to the same state 2) Continue debugging without making the change, and risk forgetting 3) Type up a reminder note to make the change All of which are annoying. Now I know that option '4) Just actually make the change' may not be possible. but does anybody know how to enable the following 'technically easy' possibility? 4) Let me change the code, get it flagged with the purple squiggly underline, so I can save it, but just ignore the change until recompile I have checked the Tools|options|debug|edit and continue, nothing appears to let me do this. thanks!

  • Google's Geocoder returns wrong country

    - by 6bytes
    Hi I'm using Google's Geocoder to find lat lng coordinates for a given address. var geocoder = new google.maps.Geocoder(); geocoder.geocode( { 'address': address, 'region': 'uk' }, function(results, status) { if(status == google.maps.GeocoderStatus.OK) { lat: results[0].geometry.location.lat(), lng: results[0].geometry.location.lng() }); address variable is taken from an input field. I want to search locations only in UK. I thought that specifying 'region': 'uk' should be enough but it's not. When I type in "Boston" it founds Boston in US and I wanted the one in UK. How to restrict Geocoder to return locations only from one country or maybe from a certain lat lng range? Thanks

  • Reading Stacktrace in Objective-C?

    - by yar
    I don't like real-time debugging much, but if it's necessary I'll do it. Is there any way to figure out what line of code a StackTrace in Objective-C refers to? What about the variable it refers to? For instance: 2010-05-13 19:39:11.673 Thingers[21003:207] *** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0 2010-05-13 19:39:11.674 Thingers[21003:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString count]: unrecognized selector sent to instance 0x3b0ebb0' 2010-05-13 19:39:11.675 Thingers[21003:207] Stack: ( 29303899 ... 11130 ) I see that we're talking about sending a count message to something that doesn't have it (maybe it's a NSCFString?), but is there any way to figure out what a/the named reference to that instance (0x3b0ebb0) refers to?

  • Flash AS3: crop TextField content off at X lines, add '...' at the end

    - by matt lohkamp
    There's only room for three lines of text in the interface, but the content is external and variable, and if it ends up taking up more than three lines, there needs to be some sort of 'view all' button functionality. I can kind of think about what that function needs to look like, but I'm not quite sure what the best way to do it in AS3 would be. Something like (in pseudo code): function cropText(source:TextField, length:int, append:String):TextField{ if(source.lineCount > length){ source.text = // magic function that retuns the first length lines, // minus append.length characters, with the append value tacked onto the end } return source; } ... right? How would you fill in the missing bit?

  • cmake add_library at a custom location

    - by celil
    I need to build a library that is to be placed at a custom location stored in the variable CUSTOM_OUTDIR. Currently, I am using the following code to make sure that the library is copied to its proper location. ADD_LIBRARY(example MODULE example.c) GET_TARGET_PROPERTY(FILEPATH example LOCATION) ADD_CUSTOM_COMMAND( TARGET example POST_BUILD COMMAND ${CMAKE_COMMAND} ARGS -E copy ${FILEPATH} ${CUSTOM_OUTDIR} ) However, this is not a good solution as the copying is done post_build, and I end up with two copies of the library. Is there a way to setup CMAKE_BINARY_DIR just for the example library so that only one copy of it is kept in the proper location?

  • Is it Pythonic to have a class keep track of its instances?

    - by Lightbreeze
    Take the following code snippet class Missile: instances = [] def __init__(self): Missile.instances.append(self) Now take the code: class Hero(): ... def fire(self): Missile() When the hero fires, a missile needs to be created and appended to the main list. Thus the hero object needs to reference the list when it fires. Here are a few solutions, although I'm sure there are others: Make the list a global, Use a class variable (as above), or Have the hero object hold a reference to the list. I didn't post this on gamedev because my question is actually more general: Is the previous code considered okay? Given a situation like this, is there a more Pythonic solution?

  • How do I enumerate a list of interfaces that are directly defined on an inheriting class/interface?

    - by Jordan
    Given the following C# class: public class Foo : IEnumerable<int> { // implementation of Foo and all its inherited interfaces } I want a method like the following that doesn't fail on the assertions: public void SomeMethod() { // This doesn't work Type[] interfaces = typeof(Foo).GetInterfaces(); Debug.Assert(interfaces != null); Debug.Assert(interfaces.Length == 1); Debug.Assert(interfaces[0] == typeof(IEnumerable<int>)); } Can someone help by fixing this method so the assertions don't fail? Calling typeof(Foo).GetInterfaces() doesn't work because it returns the entire interface hierarchy (i.e. interfaces variable contains IEnumerable<int> and IEnumerable), not just the top level.

  • Ajax method within a added method in jQuery validator

    - by nikospkrk
    Hi, I'm kind of stuck with this pretty simple (I'm sure) jQuery/Javascript issue. Here's the code : jQuery.validator.addMethod("emailExists", function(value, element, param) { var email = value || ''; var valid = 0; $.ajax({ type: "POST", url: param, data: "email=" + email, success: function(msg) { if (msg != '' && msg) { valid = 0; } else { valid = 1; } } }); return valid; }, "* Email address already registered, please login."); This function is called where a user type his email address in a registration form, and everything seems to work perfectly, except that my valid variable returned isn't updated, whereas when I use an alert box it is properly done! It looks like it return the value before the AJAX is done, any idea? Cheers, Nicolas.

  • PHP - a different open_basedir per each virtual host

    - by Lopoc
    Hi I've came across on this problem, I have a sever running apache and php. We have many virtual hosts but we've noticed that a potentially malicious user could use his web space to browse other user's files(via a simple php script) and even system files, this could happens due to the php permissions. A way to avoid it is to set the open_basedir var in php.ini, yhis is very simple in a single host system, but in case of virtual hosts there would be a basebir per each host. Ho can I set dis basedir per each user/host? is there a way to let apache hereditate php privileges of the php file that has been requested E.G. /home/X_USER/index.php has as owner X_USER, when apache read the file index.php it checks its path and owner, simply I'm looking for a system set php basedir variable to that path. Thank in advance Lopoc

  • How do I Resolve dependancies that rely on transient context data using castle windsor?

    - by Dan Ryan
    I have a WCF service application that uses a component called EnvironmentConfiguration that holds configuration information for my application. I am converting this service so that it can be used by different applications that have different configuration requirements. I want to identify the configuration to use by allowing an additional parameter to be passed to the service call i.e. public void DoSomething(string originalParameter, string callingApplication) What is the recommended way to alter the behaviour of the EnvironmentConfiguration class based on the transient data (callingApplication) without having to pass the callingApplication variable to all the component methods that need configuration information?

  • Custom Display Form with Custom Workflow button

    - by Ifi
    I have created a new custom list form that will show 4 fields on the page from a Custom List called "Shipment". I have added Form Action button that I would like to run a custom action that is set inside of a Workflow. Currently, the form displays the fields for "Manifest Number", "Pickup Location", "Delivery Location", & "Scheduled Pickup Time". When the user clicks the Form Action button, what I want the Workflow to do is go to the ID field of the displayed content in the Form and change the value of the "Picked Up" column from No to Yes. The problem I am having is passing the ID of the displayed information from the Form to the Workflow as a variable. I can get the "Picked Up" column to update if I specify the value in the "Update List Item" window under the "Find the List Item" section, but I cannot figure out how to do this dynamically from the Form

  • Closest Approach question for math/physics heads

    - by Kyle
    I'm using a Segment to Segment closest approach method which will output the closest distance between two segments of length. These objects are moving at variable speed each, so even when it succeeds I'm currently using a 10-step method and calculating the distance between 2 spheres as they move along the two segments. So, basically the length of each segment is the object's traverse in the physics step, and the radius is the objects radius. By stepping, I can tell where they collide, and if they collide (Sort of; for the MOST part.).. I get the feeling that there could be something better. While I sort of believe that the first closest approach call is required, I think that the method immediately following it is a TAD weak. Can anyone help me out? I can illustrate this if needed. Thanks alot!

  • How to get a handle/reference to the current controller object inside a rails functional test?

    - by Dave Paroulek
    I must be missing something very simple, but can't find the answer to this. I have a method named foo inside bar_controller. I simply want to call that method from inside a functional test. Here's my controller: class BarsController < ApplicationController def foo # does stuff end end Here's my functional test: class BarsControllerTest << ActionController::TestCase def "test foo" do # run foo foo # assert stuff end end When I run the test I get: NameError: undefined local variable or method `foo' for #<BarsControllerTest:0x102f2eab0> All the documentation on functional tests describe how to simulate a http get request to the bar_controller which then runs the method. But I'd just like to run the method without hitting it with an http get or post request. Is that possible? There must be a reference to the controller object inside the functional test, but I'm still learning ruby and rails so need some help.

  • Retrieving part of a string using jQuery / JavaScript

Here are some characteristics of this name attribute. It will always be in this format string[string][string] Each of the strings can be any length How would I get the some_random_text string? I'd like to stick to the standard set of functions if possible.

  • How do I change variables from different classes?

    - by Dan T
    Before I delve into it, I'm very new to Android and I have just started learning Java last month. I've hit bumps while trying to develop my first simple app. Most of these hurdles were jumped thanks to random tutorials online. MY CODE IS VERY MESSY. Any tips are appreciated. The question above is quite broad, but this is what I want to do: It's a essentially a blood alcohol content calculator / drink keeper-tracker. Basic layout: http://i.imgur.com/JGuh7.jpg The buttons along the bottom are just regular buttons, not ImageButtons (had problems with that) Here's some example code of one: <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_marginRight="5dp" android:background="@drawable/addbeer"/> The buttons and TextView are all in main.xml. I have variables defined in a class called Global.java: package com.dantoth.drinkingbuddy; import android.app.Activity; public class Global extends Activity{ public static double StandardDrinks = 0; public static double BeerOunces = 12; public static double BeerPercentAlcohol = .05; public static double BeerDrink = BeerOunces * BeerPercentAlcohol; public static double BeerDrinkFinal = BeerDrink * 1.6666666; public static double ShotOunces = 1.5; public static double ShotPercentAlcohol = .4; public static double ShotDrink = ShotOunces * ShotPercentAlcohol; public static double ShotDrinkFinal = ShotDrink * 1.6666666; public static double WineOunces = 5; public static double WinePercentAlcohol = .12; public static double WineDrink = WineOunces * WinePercentAlcohol; public static double WineDrinkFinal = WineDrink * 1.6666666; public static double OtherOunces; public static double OtherPercentAlcohol; public static double OtherDrink = OtherOunces * (OtherPercentAlcohol * .01); public static double OtherDrinkFinal = OtherDrink * 1.6666666; public static double GenderConstant = 7.5; //9 for female public static double Weight = 180; public static double TimeDrinking = 60; public static double Hours = TimeDrinking / 60; public static double Bac = ((StandardDrinks / 2) * (GenderConstant / Weight)) - (0.017 * Hours); } The last variable is the important part. It calculates your BAC based on the factors involved. When I press the add beer button (Button01) I make it add 1 to StandardDrinks, simulating drinking one beer. The other variables in the Bac formula have values assigned to them in Global.java. The code that makes the beer button do stuff is in my regular class, drinkingbuddy.java: public class DrinkingBuddy extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button button = (Button) findViewById(R.id.Button01); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Global.StandardDrinks = Global.StandardDrinks + Global.BeerDrinkFinal; Toast.makeText(DrinkingBuddy.this, "Mmmm... Beer", Toast.LENGTH_SHORT).show(); } }); By my perception, StandardDrinks should now have a value of 1. However, when I click the Calculate BAC button (Button05) it merely outputs the variable Bac as if StandardDrinks was still set to 0. Here is the code for the Calculate BAC button (Button05): Button button4 = (Button) findViewById(R.id.Button05); button4.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { TextView texty; texty = (TextView) findViewById(R.id.texty1); texty.setText("Your BAC is " + Global.Bac ); } }); It outputs the following to the text view: "Your BAC is -0.017". This is the Bac value for if StandardDrinks was still 0, so obviously there is some problem communicating between the classes. Can anyone help me?? The other elements of the formula (weight, time spent drinking, and the alcohol %'s and such) are variables because I will ultimately allow the user to change those values in the settings. I've heard around the water cooler that global variables are not good programming style, but this is the closest I've come to getting it to work. Any other ways of doing it are very much welcomed!
