  • No route matches error with application_controller spec

    - by Eric M.
    I have an application_controller spec that is failing since I removed the controller/action route from routes.rb. I get the following error: No route matches {:controller=>"application", :action=>"index"} I had many tests fail in the same way, but was able to fix them by including the correct parameters in the get call. So for instance, if I wanted to get the standard show route for posts in my spec, I had to change get :show to get :show, :id => '1' Unfortunately, I'm not sure now what to pass along for the application controller specs. I've included my test below. describe ApplicationController do it "should find the latest published posts and assign them for the view" do Post.should_receive(:latest).and_return(@posts) get :index assigns[:posts].should == @posts end it "should find the latest approved comments and assign them for the view" do Comment.should_receive(:latest).and_return(@comments) get :index assigns[:comments].should == @comments end end

  • Why can't I access a web app running on my Mac via my iPhone?

    - by bpapa
    I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator. But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server. Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?

  • how to set a tableview delegate

    - by dubbeat
    Hi, I'm trying to use a tableview without using a nib and without using a UITableViewController. I have added a UITableView instance to a UIViewController Like So mytable = [[UITableView alloc] initWithFrame:CGRectMake(22, 207, 270, 233)]; [mytable setDelegate:self]; [self.view mytable]; Also I have added the following table view methods to my UIViewController (cut for brevities sake) - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { I am getting a warning saying that my UIViewController does not implement UITableView delegate protocol. Whats the correct way to tell the table view where its delegate methods are? (This is my first attempt at trying to use a UITableView without selecting the UITableTableview controller from the new file options)

    - by Ronnie
    Hi all, Im new to Redmine. I installed redmine(with mysql) on Ubuntu 10.04. The following were the installation steps i did: $ sudo apt-get install redmine redmine-mysql subversion $ ln -s /usr/share/redmine/public /var/www/redmine In /etc/apache2/mods-available/passenger.conf, added a PassengerDefaultUser www-data directive. Configured the /var/www/redmine location in /etc/apache2/sites-available/default: RailsBaseURI /redmine PassengerResolveSymlinksInDocumentRoot on $ sudo a2enmod passenger I then restarted the apache2 server. Thats it. Now i typed http://localhost/redmine/ in my browser and accessed my redmine instance.

  • Facebook photo additions showing as separate / individual posts

    - by user1143693
    When posting additional photos to an existing Facebook album, each individual photo is being displayed on the mobile Facebook view as a separate post. Desktop display still groups them (correctly) into 1 album and shows as a single post. For instance, if I add 20 photos to an album, the people who have liked my page will see 20 individual posts in their feed from my account on their mobile devices. This has been happening for about 2 weeks now as far as I've noticed. My upload process has not changed. I should note that I've noticed this behavior by uploading via Lightroom as well as through the direct Facebook interface. Has anyone else experienced this? Did something change that I am not aware of? Thanks.

  • Best solution for language documentation.

    - by Simone Margaritelli
    I'm developing a new object oriented scripting language and the project itself is quite ready for audience now, so i'm starting to think about a serious (not as "drafty" as it is right now) way of document its grammar, functions from standard library and standard library classes. I've looked a bit around and almost every language hash its own web application for the documentation, Python uses Sphinx for instance. Which is the best PHP (don't have the time/will to install mod_who_knows_what on my server) application to accomplish this? I've used mediawiki a bit but i found its tag system a little bit hard to use in this context. Thanks for your answers.

  • Dynamically Loading a DLL

    - by TooFat
    I am trying to simply load a dll written in C# at run time and create an instance of a class in that dll. Assembly a = Assembly.LoadFrom(@"C:\Development\DaDll.dll"); Type type = a.GetType("FileReleaseHandler", true); TestInterface.INeeedHelp handler = Activator.CreateInstance(type) as TestInterface.INeeedHelp; No errors are thrown, and if I step through the code I can walk though the FileReleaseHandler Class as it executes the constructor but the value of handler is always null. What am I missing here? or even is there a better way I should be going about this?

  • Ruby on Rails - Send JavaScript to view

    - by Eef
    Hey, I am creating a website in Ruby on Rails. I have a controller action that renders a view like so: def show time_left = Time.now.to_i - 3.hours.to_i @character = current_user.characters.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @character } end end This is fine as it renders the show.html.erb as I like. I would like however to somehow pass time_left to the view as a Javascript variable as this value is use by a countdown JQuery plugin. I could put a javascript block on the page in the HTML and print a instance variable out like so: <script type="javascript"> $('#countdown').countdown('<%= @time_left =>')</script> But I would like to keep all my JS in a external file and off the page could anyone give some advice on how to implement this? Cheers Eef

  • Connecting data to a GUI - OOP

    - by tau
    I have an application with several graphs and tables on it. I worked fast and just made classes like Graph and Table that each contained a request object (pseudo-code): class Graph { private request; public function setDateRange(dateRange) { request.setDateRange(dateRange); } public function refresh() { request.getData(function() { //refresh the display }); } } Upon a GUI event (say, someone changes the date range dropdown), I'd just call the setters on the Graph instance and then refresh it. Well, when I added other GUI elements like tables and whatnot, they all basically had similar methods (setDateRange and other things common to the request). What are some more elegant OOP ways of doing this? The application is very simple and I don't want to over-architect it, but I also don't want to have a bunch of classes with basically the same methods that are just routing to a request object. I also don't want to set up each GUI class as inheriting from the request class, but I'm open to any ideas really.

  • Making a relevant search of text in database using regex

    - by madphp
    Can anyone tell me how I could count the possible instances of a keyword in a block of text? I've split a search term up into separate tokens, so just need to run through and do a count for every instance and removing punctuation or other special characters when making the count. Secondly, if someone has inserted search terms surrounded by double quotes, i want to be able to skip explode, but just count instances of that exact phrase. It doesn't have to be case sensitive and I would like to remove punctuation from the phrase when doing the count. Thirdly, in both cases i want to be able to ignore wordpress and html tags. Lastly, if anyone know any good tutorials for relevant searches that answer the questions above, that would cool too. I've got this far. $results = $wpdb->get_results($sql); $tokens = explode('search_terms'); // Re-arrange Relevant Results foreach ($results As $forum_topic){ foreach($tokens As $token){ // count tokens in topic_title if ($token ){ } } }

  • what kind of credentials/prerequisites do you need to be a professional penetration tester ?

    does it take more than knowing Bt4 ? are there any one that just runs a scanner and no real labor involved ? would you be expected to be able to code your own exploits without having to dl from milw0rm and discover entry into a system by yourself, in other words, do you have to think outside the box even when there's so many tools that makes the job a lot easier ? would you ever be expected to be able to write your own scanners, exploits and etc ? i am also curious how people are able to write long pages of hex address, that magically causes some type of memory overflow...how are people guessing at the hex values for game hacks for instance ? are certification important ? what about formal school education ?

  • Policy based design and defaults.

    - by Noah Roberts
    Hard to come up with a good title for this question. What I really need is to be able to provide template parameters with different number of arguments in place of a single parameter. Doesn't make a lot of sense so I'll go over the reason: template < typename T, template <typename,typename> class Policy = default_policy > struct policy_based : Policy<T, policy_based<T,Policy> > { // inherits R Policy::fun(arg0, arg1, arg2,...,argn) }; // normal use: policy_base<type_a> instance; // abnormal use: template < typename PolicyBased > // No T since T is always the same when you use this struct custom_policy {}; policy_base<type_b,custom_policy> instance; The deal is that for many abnormal uses the Policy will be based on one single type T, and can't really be parameterized on T so it makes no sense to take T as a parameter. For other uses, including the default, a Policy can make sense with any T. I have a couple ideas but none of them are really favorites. I thought that I had a better answer--using composition instead of policies--but then I realized I have this case where fun() actually needs extra information that the class itself won't have. This is like the third time I've refactored this silly construct and I've got quite a few custom versions of it around that I'm trying to consolidate. I'd like to get something nailed down this time rather than just fish around and hope it works this time. So I'm just fishing for ideas right now hoping that someone has something I'll be so impressed by that I'll switch deities. Anyone have a good idea? Edit: You might be asking yourself why I don't just retrieve T from the definition of policy based in the template for default_policy. The reason is that default_policy is actually specialized for some types T. Since asking the question I have come up with something that may be what I need, which will follow, but I could still use some other ideas. template < typename T > struct default_policy; template < typename T, template < typename > class Policy = default_policy > struct test : Policy<test<T,Policy>> {}; template < typename T > struct default_policy< test<T, default_policy> > { void f() {} }; template < > struct default_policy< test<int, default_policy> > { void f(int) {} }; Edit: Still messing with it. I wasn't too fond of the above since it makes default_policy permanently coupled with "test" and so couldn't be reused in some other method, such as with multiple templates as suggested below. It also doesn't scale at all and requires a list of parameters at least as long as "test" has. Tried a few different approaches that failed until I found another that seems to work so far: template < typename T > struct default_policy; template < typename T, template < typename > class Policy = default_policy > struct test : Policy<test<T,Policy>> {}; template < typename PolicyBased > struct fetch_t; template < typename PolicyBased, typename T > struct default_policy_base; template < typename PolicyBased > struct default_policy : default_policy_base<PolicyBased, typename fetch_t<PolicyBased>::type> {}; template < typename T, template < typename > class Policy > struct fetch_t< test<T,Policy> > { typedef T type; }; template < typename PolicyBased, typename T > struct default_policy_base { void f() {} }; template < typename PolicyBased > struct default_policy_base<PolicyBased,int> { void f(int) {} };

  • Django models & Python class attributes

    - by Geo
    The tutorial on the django website shows this code for the models: from django.db import models class Poll(models.Model): question = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') class Choice(models.Model): poll = models.ForeignKey(Poll) choice = models.CharField(max_length=200) votes = models.IntegerField() Now, each of those attribute, is a class attribute, right? So, the same attribute should be shared by all instances of the class. A bit later, they present this code: class Poll(models.Model): # ... def __unicode__(self): return self.question class Choice(models.Model): # ... def __unicode__(self): return self.choice How did they turn from class attributes into instance attributes? Did I get class attributes wrong?

The registartion for the handler is done as below: private void InitializeComponent() { this.dtgBatches.SortCommand += new System.Web.UI.WebControls.DataGridSortCommandEventHandler(this.dtgBatches_SortCommand); }

  • How does one refer to the game1 class's variables in XNA

    - by user1149068
    I try to refer to an array in the Game1 class by creating an object of the Game1 class with its definition Game1 gameObject; , its declaration gameObject = new Game1(); in the constructor, and its usage gameObject.tileArray[xInt, yInt].treed = true;. The game1 class itself remains unchanged in its class code other than some methods and variables. When I try to use this code in the TreeRegion class it gives me "Object reference not set to an instance of an object," leading me to believe that the game1 class is null somehow. How might one change the class or object in order to refer to game1's variables? Mind you I am self-taught and still rather new to C#. The class that refers to game1: http://pastebin.com/0chEcKfq Game1 itself http://pastebin.com/zLDVzCca

  • Oracle SQL Update query takes days to update

    - by B Senthil Kumar
    I am trying to update a record in the target table based on the record coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. I find that the Informatica code is perfectly fine looking at the Informatica session log but its in the update it takes long time (more than 5 days to update one million records). Any suggestions as to what can be done on the scenario to improve the performance?

  • Binning into timeslots - Is there a better way than using list comp?

    - by flyingcrab
    I have a dataset of events (tweets to be specific) that I am trying to bin / discretize. The following code seems to work fine so far (assuming 100 bins): HOUR = timedelta(hours=1) start = datetime.datetime(2009,01,01) z = [dt + x*HOUR for x in xrange(1, 100)] But then, I came across this fateful line at python docs 'This makes possible an idiom for clustering a data series into n-length groups using zip(*[iter(s)]*n)'. The zip idiom does indeed work - but I can't understand how (what is the * operator for instance?). How could I use to make my code prettier? I'm guessing this means I should make a generator / iterable for time that yields the time in graduations of an HOUR?

  • iPhone: TabBarController as second level of Navigation Controller

    - by Nebs
    I'm new to iphone development. I've read tutorials about implementing a tab bar controller on the window (eg as the main controller for the app). But how can I create a tab bar controller as a 'standalone' UIViewController that can be called by a navigation bar controller? Basically my navigation bar controller has an array of UIViewControllers that it displays in the table and then loads the appropriate view/controller when a user selects an item. Now I want one of these loaded views/controllers to be a tab bar controller. How can I do this? I'm not sure how to create a tab bar controller on its own without having an outlet/instance in the application delegate. Hope that made sense. Thanks.

  • Pass complex objects to MVC Get parameters

    - by VJ
    I am wanting to pass something like the following to my view from my controller via GET not POST: public class MyDTO { public string val1 { get; set; } public string val2 { get; set; } public MyObject obj { get; set; } } public class MyObject { public int SomeInt { get; set; } public string ACoolValue { get; set; } public string YetAnotherCoolValue { get; set; } } And then the controller would like like this. (Note it is a GET): public ActionResult MyView(MyDTO dto) { return View(dto) } The problem is that the instance of MyObject is coming back as null, where val1 and val2 have data. Has anyone run across this?

  • How do you PEP 8-name a class whose name is an acronym?

    - by Arrieta
    I try to adhere to the style guide for Python code (also known as PEP 8). Accordingly, the preferred way to name a class is using CamelCase: Almost without exception, class names use the CapWords convention. Classes for internal use have a leading underscore in addition. How can I be consistent with PEP 8 if my class name is formed by two acronyms (which in proper English should be capitalized). For instance, if my class name was 'NASA JPL', what would you name it?: class NASAJPL(): # 1 class NASA_JPL(): # 2 class NasaJpl(): # 3 I am using #1, but it looks weird; #3 looks weird too, and #2 seems to violate PEP 8. Thoughts?

  • C#.NET : A graphical control makes my app freeze after workstation unlock

    - by leo
    Hi, I have a graphical control that is multithreaded. Until now it worked fine, but I just noticed that whenever I'm on my application showing this control the following happens: if I lock and unlock my workstation, it freezes, like if it were in some kind of infinite loop. Even stranger, this bug occurs only when I'm not lauching the app from Visual Studio, and not attached to it. Does anyone have a clue on what's happening? For instance, if I attach Visual Studio to the already freezed app, can I see which lines of code my threads are executing ? Any help will be appreciated!

  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

  • What is the easiest way to send a Javascript array via JSON to PHP?

    - by dscher
    I have a few arrays that I want to send to process with PHP. Using json2.js I will stringify the arrays like so: var JSONlinks = JSON.stringify(link_array); var JSONnotes = JSON.stringify(note_array); but then I'm confused. Do I need to use a XMLHttpRequest object? Is there another way? If that is the simplest way, could someone please just share the most basic instance of the code needed in order to send to PHP where I can then use JSON decode? I think it might help others in the future really. I'm currently using Jquery and I know there are many options out there for frameworks and each one may or may not make this process any easier. If you're using a framework in your reply please mention why you'd choose that framework rather than just javascript.
